*either![]()
if you mind your safety precautions, you can do quite alot safely. for example: me and some people at the local hackerspace made RFNA for decapping chips, which would be pretty dangerous if we hadn't thought out containment,PPE and waste handling![]()
I'v read a bit into x-ray safety a while ago. correct me if I'm wrong but shielding and distance is key. And it's surprising how little shielding small sources such as a dental xray actually need![]()
yeah... i think the felling is mutual..![]()
@Ben Krasnow do you still have that DeLorean, and if so isn't it time to do a project with it? Alternate power source, self driving AI, or ?![]()
@Ben Krasnow I see the projects you work on that make it to your channel.. and I know how I'm like with projects. I can hardly imagine the quantity of things you have on the future to do or back burner list.![]()
Mr Fusion!!![]()
you know, thinking about it, so many people have this problem![]()
I wonder about the actual logistics of a waste management project![]()
Noel, for both my day job and Applied Science stuff, I like to keep things in my head. I don't do much external tracking with tools.![]()
For every completed thing, there's probably a dozen in various states of being done, started, not started but researched, etc..![]()
maybe somethhing like those mycology things where they grow oyster mushrooms off oil spills![]()
@Ben Krasnow you do a lot of hand written notes as yo ugo?![]()
and then use that as fertilizer since it's not really good for human consumption but it's ok at 3-4rth hand to get those calories from oil![]()
Damnit![]()
Ben: What do you find interesting from DIY the community? the different projects that people make? Are Art projects interesting to you you?![]()
Ben, what do you see as the next steps to work on to get the plating to produce a more usable product? Do you think it's largely recipe tweaking, or more post-processing, or just unknown?![]()
@Christian yes, they're helpful. But generating as little as possible and checking the shielding work are important too. Would advise buying an x-ray sensor before making x-rays.![]()
^^^![]()
Krux, it's true! Some things never make it to the channel. But since I was shorter on time since starting at Verily, I try to "economize" such that most of my work on evenings gets put into a video (eventually) --- sometimes takes years.![]()
I agree with that!![]()
@Ben Krasnow for the sake of getting these thoughts out of your head I highly recommend David Allen's "Getting Things Done" information management algorithm, basically his whole book could be summed up in the flowchart graphic, you can pair that with something like evernote as a way to keep your 'reference' materials text searchable, and it works as a repository you can put any sort of media to![]()
My final micrometeorite plug is the facebook page of OG-micrometeorite hunter Jon Larsen in case anyone wants to see what these things look like: https://www.facebook.com/micrometeorites/ There are tons of high quality photographs in there![]()
Mike, I think the most important thing in the DIY community, is building a sense of agency and control over a person's environment and life. It's a while mindset of positivity that the early years of Make magazine captured well.![]()
particularly good if you use a 'web clipper' extension to save pages (articles, news stories, etc) directly to your evernote repository![]()
makes every cool reddit find permanently text searchable if you use it, the trick is to use it, lol![]()
love too spread positivity and a love for power acquisition amongst the upper class![]()
Spencer, I don't know. It could just be parameter tuning, or the whole thing might be a dead end :)![]()
@krux @Micah Elizabeth Scott the "dumping stuff down the drain" comment is pretty illustrative: take 3D printer resin. Toxic as hell and super under-respected. But "dumping down the drain" isn't really a practical issue until it's popular enough that LOTS of people are doing it, AND a significant number aren't respecting the safety aspect. Case in point - if everybody played around with making explosives at home, there'd be a whole lot more neighbor-caused fire and destruction, which is precisely why that kind of thing is rightly illegal. Extending that to the likes of X-rays and chemistry, certainly I'm a fan of promoting respect for the various risks to prevent it from becoming a real issue.
![]()
gree @Ben Krasnow re:early make and I always felt that was an extension of the old Mother Earth News![]()
Thanks Ben! Sometimes, that's not easy to follow.. Any support groups!! :)![]()
@Ben Krasnow : one thing i've always noticed is that a lot of citizen 'science' seems to be about expermenting but no one actually seems to bother with proper scientific method: statistics, hypothesis testing, keeping detailed logs etc. Do you think that should get more attention?![]()
is making explosives at home even illegal?![]()
@Ben Krasnow , any book recommendations?![]()
second that![]()
"science" is 99% of the time a brand rather than a method here![]()
also yes it's illegal to make explosives at home, regulated by ATF![]()
Positive!!![]()
Stay Positive!![]()
@me, the ATF says "Yes"![]()
Micah I recommend science literacy before making bitchy statements about science![]()
You should make explosives at work, with a propper risk assessment![]()
scientific method FTW indeed - I've seen some outrageous claims of 'dust sensors' packaged as 'citizen' 'science'![]()
> Persons who manufacture explosives for their personal, non-business use (e.g., making fireworks to set off on your own property or mixing binary explosive components to remove a stump in your own yard) are not required to have a manufacturer’s license. However, no person may ship, transport, cause to be transported, or receive explosive materials unless such person holds a license or permit.![]()
yeah![]()
but "explosive" is a very limited definition![]()
meaning, you can make your own gunpowder![]()
but not anything STRONGER than that![]()
I think theres a large group of ppl who use "science" to mean engineering/experimenting![]()
yep![]()
Peter, yes. And to be fair, I don't really consider myself a scientist. I am an engineer, and so the goal is not to create new knowledge, but apply existing principles in new and useful ways.![]()
Kendall: what do i have to read before i'm qualified to complain about the science-flavored branding of random folks posting "science" videos on youtube![]()
eh? you need to know the difference between science and branding![]()
Micah and Peter are saying the same basic thing here, from what I can see![]()
yeah there's tards calling their dumb notions 'science' too, that's why the WHOLE IDEA is that it's a method for HOW you know shit![]()
I like the "It's not science till you wrote stuff down"![]()
branding is just applied marketing :)![]()
so you can TEST it![]()
Applied Science? :)![]()
yeah applying not discovering new![]()
he's fine![]()
"oh that means I can do X"![]()
@Ben Krasnow: i really like how you reflect that in your channel name, using the brand but being clear about it being related but not the same ("applied")![]()
i am aware of what science is, i am trying to make a distinction between what ideally the "citizen science" movement would be producing and what it actually is![]()
oh glad the arbitrator of what is science is here![]()
@Kendall Meade none of that contradicts with what Micah says, so what your issue is kinda puzzling![]()
Or is it Applied Engineering? just kidding...![]()
it would just be cool if there was some kind of accepted trend toward responsible citizen science: something that acknowledges the power of carefully recorded data, and the impacts of any experimentation on the local and broader environmnt. basic stuff obviously, but also stuff that is often left off in an effort to seem cool.![]()
@Micah Elizabeth Scott :i've seen an interesting split between "citizen science" as in crowdsourcing data collection for scientists, citizens doing scientific investigations of issues (for example, HAMs finding out interference sources) and its maker interpretation of messing around with experimental $field stuff.![]()
micah are you against joyrides?![]()
Ben: I am curious, do you have have family members that understand some of the things that you do?![]()
so you're making sweeping and meaningless generalizations here, yeah it would be great if every would-be scientist could be part of some open source CIA for scientists, but it seems an unlikely thing to expect![]()
I think it's also fair to acknowledge that a lot of this is entertainment. I hope that my channel teaches things, and gets people thinking, but it's really a YouTube channel, and the goal is pretty much to have people spend time in an enjoyable way, and pick up a few facts that may help them later.![]()
@Micah Elizabeth Scott I wonder - when you talk about citizen science, what's the image you have in your head? Scientific method executed by citizens, or citizens participating in distributed collection efforts where a more centralized group of researchers are doing the "science"?![]()
Or like me, they are largely clueless..![]()
@Ben Krasnow one thing I wanted to ask you about your Hypercentric optics video do you know of these tube-projector lenses function on their own? I remember taking a projector apart and the cooling(?) liquid that couples the lens to the tube seemed to be part of the optical path![]()
alex: all of the above really![]()
Like Electro-Boom.. I see you follow him...![]()
> In their footsteps follow today’s citizen scientists, a relatively small cohort compared to the great numbers of professional scientists that universities churn out year after year. But where these credentialed practitioners are often hyper-focused on a particular sub-field in a highly specialized discipline, the citizen scientist enjoys more freedom to explore the universe, as his or her natural philosopher forebears did. These citizen scientists — many of whom are also traditionally credentialed — are doing important work, and some are even publishing their findings in mainstream journals.![]()
it's interesting that folks go right to assuming i don't know what i'm talking about here![]()
also bitching about "this bieber scientist isn't doing it as good as I would" seems like 1) if you have a point you should go show us what you mean with it rather than 2) attacking the guy we're all here to ask questions of, micah![]()
doesn't sound limited to distributed collection efforts![]()
Ben: just seeing all the tools and what can be done with it is great experience and motivation on dreaming and building one's own lab/experiments![]()
@Micah Elizabeth Scott ha, seems like @Peter Bosch might have beat me to the thought![]()
Ben: do you like his channel? very entertaining!![]()
@Ben Krasnow I like that you show how you got to what you accomplished.. covering a lot of the failures that led up to the eventual final result, and covering what else you still need to do.![]()
@Micah Elizabeth Scott Agree and that is a tennant of science. If you do not document sufficiently, in a very short time, it as though never happened. Is a youtube video sufficient documentation - maybe yes, maybe no..![]()
Have you though about doing another tools/tips video? I found some of the tips you had in the two last were really useful![]()
"I tried these things and they didn't work but eventually refined this method that gave me good results"![]()
@Micah Elizabeth Scott : I don't, I actually agree with most of what you've been saying.![]()
OK, folks, our time is up and we seem to have strayed a little far afield. I imagine Ben needs to get back to work, so we'll say a hearty thanks for his time.![]()
Noel: Shariar of youtube Signal Path has excessive amounts of RF equipment - and explains what can be done with the combinations of it![]()
@Micah Elizabeth Scott (mostly just the one)![]()
THANK YOU BEN!![]()
Thanks Ben! We appreciate you spending time with us today![]()
Very informative and entertaining :D![]()
Hi Ben, thanks a lot for your work and time!![]()
Thank you so much Ben![]()
Yeah agreed Shariar is great! Thanks for your time Ben!![]()
Thank Ben!![]()
good luck with project baseline and linking everyone's RNA to their google account, ttyl![]()
thanks ben!![]()
Thx Ben![]()
lol micah![]()
Thanks for being here, Ben![]()
thanks ben!Hack Chat Transcript, Part 2 04/29/2020 at 20:12 • 0 comments

@Abhishek Viswanathan this seems to fit neatly along those lines: https://www.seeedstudio.com/Smart-Citizen-Kit-p-2864.html![]()
Ben: Kind of shocked you haven't heard of them. Very cool series, more for teaching you _how_ to build machine tools, with the side affect of, well, building machine tools. It's hard to argue that for most of us it is a cost effective way to equip a shop, but it's a great set of skill building projects.![]()
I'll continue my monologue about micrometeorites for a little longer. Because one of the problems for citizen scientists in the field is to definitively prove that you have actually found something extraterrestrial. With Larsen's method you can learn how to find stuff and be pretty certain, but to be really sure you need an electron microscope and more importantly an electron microPROBE (https://en.wikipedia.org/wiki/Electron_microprobe/). It's similar to an electron microscope but uses Bragg diffraction to identify the constituent materials of the object being irradiated. Since you've built your own SEM, @Ben Krasnow, I'm really curious to hear if you've ever attempted or considering making a microprobe like that.![]()
I want to do https://amzn.com/0596514921 and https://amzn.com/1449396593 but understand others have had legal problems. I guess it's not hardware hacking really.![]()
how would you collect them?![]()
@alexwhittemore nothing too bad, have to write a reflection essay, formal warning, etc... I think having it associated with that lab might have been worse actually because I've already been politely *corrected* for having some chemicals and things in there![]()
@Ben Krasnow For your diy SEM, did you have any issues with the outgassing of the materials you used?![]()
gingery home workshop, informed by developments since then like cheap graphite for air bearings and cheap industrialized flat granite for reference surfaces, means more people could do the dan-gelbart micron-accurate grinders too Mark VandeWettering![]()
Ben: When you have done your difference project, did you have a plan for the different equipment needed? For example the SEM, and the sputtering project..![]()
@me ah I thought you only meant hardware as in electronics![]()
FYI, I'll be posting a transcript of the chat directly afterward, in case anyone misses a link or something.![]()
For example did you plan ahead the need?![]()
Kendall I'll be googling for those improvements :-)![]()
Peter, yes! I originally used acrylic (PMMA) parts, it was too much. I could tell the parts were outgassing since the pressure would go up, the more parts I put into the chamber. I switched to PTFE, which was much better, and luckily mechanically good enough for what I was doing.![]()
And the metal? what was the base plate made of?![]()
@Sam Zeloof Reflection essay thesis: "Ultimately this experience has shown me that my decisions were largely optimal given the scenario, and others would not have achieved goals as effectively" :)![]()
Aluminum. I've never had problems with metal choices in the realm of vaccum that I need.![]()
@alexwhittemore haha perfect, thank you![]()
I haven't worked with vacuum but I have heard that epoxy resins particularly have a problem of off-gassing![]()
seeing as I'm looking to start some high vacuum experiments of my own when the lockdown is over, and I've just been hearing a lot of conflicting stuff about aluminum being usable or not![]()
@Ben Krasnow how did the spark plug feedthroughs work for you? were they sealed with a crushable metal gasket or o-ring? seems like a nice cheap trick![]()
You can get away with more than what you'd believe reading the forums. Buna-n O-rings are perfectly fine, which is what I used to seal the sparkplugs. Pretty much any metal will be fine. Any plastic that smells strongly like PVC or "vinyl" tubing, should be avoided.![]()
Good evening, @Andy Geppert ! I loved to play with your magnetic core memory touch-screen at the hardware happy-hour event in SF back in February :) (I am Simen, btw)![]()
anyone else think it's worth reflecting on "citizen science" as it interacts with your neighbors' rights to safety though...![]()
@Ben Krasnow , what vacuum levels were you hitting?![]()
large rubber stops with needle pressed through was also used in some experiments![]()
@Micah Elizabeth Scott well sure![]()
Epoxy can be very good. Hysol 1C is known as a good vacuum sealant.![]()
I believe that you can get low-off gas expoy.. they are just expensive..![]()
@scanlime : thats common sense isn't it: don't do anything you can't reasonably assume is safe to the environment around you![]()
@Micah Elizabeth Scott I do - BUT I also thing it substantially comes down to "safety first" - as long as you're conducting yourself rationally and mitigating risk for yourself, that naturally extends to others.![]()
Torr Seal works well, but quite expensive. Still less expensive than off the shelf vacuum fittings.![]()
i mean, yes, but i'm also just seeing a culture of "safety third" for this stuff a lot, and this chat hasn't been taking the "reflection" seriously it seems![]()
Could this be an experiment? measure the different off-gassing of materials?![]()
@Micah Elizabeth Scott Oh well - if you work at SpaceX, sure.![]()
and point your particle accelerator only in the direction of your least favorite neighbor ;)![]()
Micah, I take it seriously. My neighbors actually discovered my channel organically, so they know what I'm up to in, at least what makes it onto YouTube, which is mostly every project.![]()
i mean, in my experience diy culture is full of folks talking a big talk about safety and then doing risky experiments in apartment buildings![]()
lab safety 101: determine the risks (worst case) of your experiment and determine the failure modes of your mitigations![]()
Ben Krasnow what would it take to convince you to do an AR15 build on the channel? :D![]()
OMG..![]()
Do mean risky as in harming themselves or others?![]()
I'm not really into guns, but don't hate them either. It's just not what my channel is about.![]()
Ben: what about Antenna projects?![]()
:)![]()
they aren't for everybody, but at a time when so many people are impulsively buying beyond their competence, it'd be nice to see level heads weighing in on them![]()
christian: yes. i mean like producing fumes in enclosed spaces, producing x-rays in a dorm room, that kind of thing. it's a risk that people nearby don't know about or consent to.![]()
Ben, is there an experiment or project you've been eager to do but have had to put off? Even a dream project.![]()
Or another way.. what are your next big Projects in mind?![]()
i'm not trying to be a pest to any one person i just see this celebrated a lot in the diy community- folks venting acid vapour out their balcony or whatever and the replies are all "lol sucks to be your neighbor" in a way which doesn't actually discourage this sort of thing at all *shrug*![]()
I think guns are an interesting "ultimate beating swords into plowshares" industrial test case, if you can manufacture a modern firearm you can basically perform all of the precision operations that are necessary to also be able to make things like car engines and electric motors and generators. I'm not some crazy "everybody should have an ak47" nutjob but I also think they can't be un-invented.![]()
Ashley, yes, an MRI machine ! Alan Yates and I had been planning it long ago. It's still on my list. There is also nuclear quadrapole resonance spectrometers, which are sometimes callled "zero field NMR".![]()
yeah, the problem is that if you make a gun...well.. you have a gun. What use is that?![]()
ben: what about building a DIY STM?![]()
I'd rather have an electron microscope.![]()
oh yeah an STM would be interesting, or AFM![]()
what non-medical uses can such MRI scanners provide ?![]()
eh? can be nothing but a fun bangstick in the best case, and used only for shooting cans, there's plenty of sports leagues for this stuff, IPSC and all![]()
guns aren't magical violence wands![]()
this isn't harry potter![]()
i've seen some people claim to do it using COTS piezo buzzers![]()
anyway, @Ben Krasnow any recommendations on the sort of TV to find that can make the best electron microscope?![]()
Whitequark was doing some STM experiments with MLCC surface-mount caps. I don't have a link handy, but it was on hackaday![]()
Ben: Are you open to the idea of a DIY community Projects?![]()
I know I need some kind of CRT with an in place and not-discharged magnetic ring![]()
you can use a gun to shoot a few balloons so you can descend https://en.wikipedia.org/wiki/Lawnchair_Larry_flight![]()
@Ben Krasnow on the topic of citizen science, I really enjoyed your research on electroless plating. Did you find the circuits you produced to be robust enough to replace other home-produced PCBs? I recall you had some peeling issues, at least at some point![]()
Or even Mentoring..![]()
https://hackaday.com/2015/08/20/using-a-capacitor-as-an-actuator/ ?![]()
I'm trying to work my way back into telescope making/optical fabrication, and an interferometer is on my list of todos.![]()
I just built a face mask sanitizer using an old EPROM eraser UVC lamp![]()
oh yeah also on the subject of projects, @Ben Krasnow do you have a github that you can put up so that people can build along or maybe even make submissions to?![]()
Spencer, no. It needs more work to be ready for beta testing. I haven't developed it since presenting at Supercon.![]()

duuuuh thanks, I'm a googletard, lol![]()
followed :D![]()
@Mark VandeWettering - beats the plant pots I'm presently printing![]()
@Micah Elizabeth Scott when I think about it I've seen some really stupid stuff that's dangerous to others/the environment. But on the other hand I think that most regulations are meant for commercial applications ie doint stuff all the time. So the causal chemist or the hardly used x-ray source should not pose a too great risk. but you are absolutly right I rather like to know it when someone is opperation an x-ray source nearby![]()
Ben: Are you open to the idea of a DIY community Projects? Or Mentoring projects?![]()
how much can you mitigate the risks of Xray stuff by either a) doing it in a basement with shielding over the top so that it's insulated by the earth, or b) doing some kind of rammed earth arrangement to bring that 'earth shielding above ground' in something like an earthship?![]()
if everyone believes they're not doing "too much harm", you make a lot of collective harm![]()
Mike, I guess it depends on the project specifics![]()
also speculating on the exact intention of laws seems dangerous![]()
shiz, the problem is that if everybody can do 'no harm' nothing gets done![]()
*citation needed![]()
I am back.![]()
Can we make a Proposed Project Web Site?![]()
that's a rather sweeping statement without any backup![]()
so was yours, lol![]()
I agree you have to not be short sighted on what do do with waste products, what electrical emissions you are producing, etc.. that's a being good to yourself, your neighbors, and the planet kind of thing. A lot of people don't think of that. Can't just dump random chemicals down the drain type of stuff.![]()
@Kendall Meade http://www.radprocalculator.com/Gamma.aspx is excellent for working out dose rate calculations![]()
Take in Idea's and choose?![]()
noice, thanks phil :D![]()
Mike, yes I started a reddit for the purpose of voting/generating project topics. It's been a while since I checked in...![]()
oh really? wow..![]()
do you have a link.. or would a different forum work better for you..![]()
electrical emissions are worst on low frequencies and long wires - the higher the frequency, the less problems in the long range![]()

OK everyone, let's get started. We're excited to have Ben Krasnow on the Hack Chat today. Welcome Ben!
![]()
Hello!![]()
Hi!![]()
how's it going :D![]()
Hello everyone :-)![]()
Hey hey![]()
I think everyone knows you pretty well, but maybe you could give us a little about yourself?![]()
Hi, Ben! Good to see you![]()
Sure. I work at Verily (Google Life Sciences) doing hardware prototyping. The goal is to make devices that detect disease earlier in progression when it is often cheaper and easier to treat. I also host the Applied Science channel on YouTube, where I show interesting and practical applications of scientific principles. Thanks for having me on the chat.![]()
dude thanks for being here :D![]()
Thanks for being here![]()
Hi Ben!!![]()
so, WHAT ABOUT hydrogen blimp quad drones, lol![]()
Are you currently working on anything for the Covid-19? or you can;t say...![]()
hi ben your my hero!![]()
always love seeing your videos and thought process!![]()
I have mostly been focused on early cancer detection projects.![]()
ah .![]()
nanotech stuff?![]()
hang on, are you one of the guys using radar as a medical imaging technology?![]()
is this the right language![]()
As it turns out, in order for cancer cells to continue their rapid growth, they end up burning fuel in a less efficient way that creates literal dirty exhaust in the blood stream. Detecting trace amounts of this would be a very good way to search for latent cancers.![]()
Ben, can I ask you to take a look at a few seconds of this video? It's a droplet of water on a film of carbon black, which you can make by just putting a candle underneath a glass slide. It has some really interested properties that reminded me of your graphite air bearing![]()
In your experience, what have you found as a significant stumbling block for people to start or sustain a local-scale citizen science project?![]()
woo, back! Hi ben!![]()
Are you working on any sensors for detection of alkanes and aromatic compounds generated by malignant tumors.....from the canine reports?![]()
What are these 'dirty exhaust' exhaust you are looking for and how do you detect them?![]()
regarding applied science, given 1000 different interests, how do you manage to finish any darn project? Any tips?![]()
And does this method work for all types of cancers?![]()
I think a very common stumbling block for any type of project is building consensus of setting goals. For market-driven companies, it's a little more clear because customers ultimately decide with their wallet. For efforts that are not pushed by consumerism, it becomes more difficult to assess if a goal is being met.![]()
DrG, yes along those lines!![]()
Is your laboratory at your residence? If so, have there been any zoning law problems?![]()
heh, or fed visits...![]()
Wish my garage was tidier (and a lot bigger), would be awesome to have a similar setup![]()
Ahron, that's cool!![]()
lightning phil just start with tidying the garage up and fitting what you can in there, and actually doing the stuff you can do![]()
all this media hype and you can still make an ar15 at the average kitchen table![]()
Yes, my lab is my home garage. I used to work here full-time when I owned my own MRI devices business.![]()
hold up you made mri's as a business?![]()
what's that like![]()
I see you use a Source Measurement Unit for some experiments, do you have any suggestions for measuring really low, complex impedances, like Lithium ION cells, Electrochemical impedance spectroscopy or Dielectric spectroscopy ?![]()
I made MRI-compatible computer peripherals (keyboards, mice, etc) for use in cognitive experiments.![]()
Any trouble with the government?![]()
I remember , no metal parts... whatsoever![]()
oh that's cool :D![]()
Cool. The Fiancee does cognitive experiments.![]()
fiber optics based..![]()
Since the topic of this chat is "citizen science" I wanted to bring up a concept that has been stealing a lot of my attention lately: micrometeorites. Their existence has been known for a long time, but until around 2015 it was assumed by most scientists that they corroded away almost immediately upon landing on earths surface. This was disproved by a (literal) Norwegian Jazz musician named Jon Larsen when he was able to develop a method for finding and identifying these tiny objects in urban environments. Now, he (and other scientists in the field) is calling upon more citizen scientists to do like him to help improve those methods as it can make a huge impact on the field. Has anyone here ever considered doing or done something like that?![]()
so you did stuff for active brain imaging as people were performing tasks or undergoing neurological events or whatever?![]()
I remember the concept of the computer mouse it's both simple and ingenious![]()
Other than that funny X-ray problem, I haven't had any trouble working here.![]()
does a faraday cage work for xrays![]()
Ah, the backscatter X-ray machine chicken experiment ? :)![]()
or can one be made to?![]()
Ben, I love your work and excellent explanations. Are you based in Palo Alto?![]()
lead?![]()
Thanks ben! Glad you got to me in this torrent of fans :)![]()
Ben, I have a lot of surplus HV kit. It's in the UK, which isn't convenient, especially now. Happy to figure out a way of overcoming that though.![]()
Sigh... why isn't there a central moderator to funnel questions to? This is a messy free-for-all.![]()
Do you still have your delorean car? :)![]()
@Applied Procrastination - I think The Thought Emporium did a video about that, collecting micrometeroids from rooftops.![]()
I spent a couple of afternoons searching for iron tektites in at the bottom of downpouts in my house by using a magnet. I didn't discover anything that I thought positively was a tektite, but my attempt was half hearted.![]()
what was your x-ray issue? i recently got into trouble from my university for having an x-ray in my dorm room, they were not happy about this one![]()
hahaha sam![]()
I was just about to ask about that, when I was doing vacuum experiments I noticed that one time when my vacuum became too soft and gas discharge occurred it seemed (according to my geiger counter) to start producing a bunch of Xrays even though the largest voltage differential was only about 500 V![]()
That was probably noise pickup![]()
I wonder where the cheapest place without legal impediments to hardware hacking is![]()
I have this book, which has some interesting pictures: https://www.amazon.com/Search-Stardust-Micrometeorites-Terrestrial-Imposters/dp/076035264X![]()
hardware hacking in general or stuff with x-rays?![]()
@Sam Zeloof IIRC, a neighbor caught wind that he had an X-ray source in the garage and he got a visit from a nice government man who decided his shielding precautions were sufficient?![]()
@Dan Maloney That is probably true, Hackaday has even written an article about it a while back :) I'm considering making a YouTube video on it myself as well (well, I will probably do that at some point to be honest). It's just a field where I see sooo many potential projects and improvements that can be made that actually have the potential to make a scientific impact![]()
Applied Proc, that's pretty interesting. I hadn't heard of this. There is always a sort of tension between "leave it to the experts", and just doing things because they seem interesting and useful. It's a pretty fine line, and even before covid, there is a lot of room between too much emphasis placed on experts, and too much wild west.![]()

Fantastic Micrometeorites And Where To Find Them
Space is very much the final frontier for humanity, at least as far as our current understanding of the universe takes us. Only a handful of countries and corporations on Earth have the hardware to readily get there, and even fewer are capable of reaching orbit.

Hah, I was just about to link to that article![]()
@Christian hardware hacking in general![]()
re "experts" vs everyone-for-themselves, it's worth considering your impact on local environment and on the supply chains. if you can build one of something in your garage but you need a hundred thousand of them, it's unlikely the work you did to figure out materials for that one is going to help![]()
Ben: that's a line you walk really well. I admire the thoroughness and discipline of your approach, but even more your ability to just actually do the hard work, rather than be intimidated by it.![]()
me: what sort of legal impediments? don't know about US law but if its not professional scale you should be fine doing it at home, right?![]()
plenty of amateur scientists have been raided![]()
except for radiation/hazardous materials![]()
especially with the rise of meth labs etc![]()
Long ago, someone reported me to some kind of authority for showing an X-ray (CT scanner) in my video. I eventually was contacted by state officials, and they were very polite and helpful. :)![]()
how's the cookie machine?![]()
@Ben Krasnow You are an inspiration to many of us and I really want to thank you for your efforts, your channel, your excellence.![]()
Ben: did the person contact you first before reporting ?![]()
One of the really intriguing projects I see in Micrometeorite research is attempting to implement a visual classifying algorithm. This is not my expertise, so I'm not sure if I'll attempt it, but something like that would make a huge impact on the field (the field is quite small obviously). Even if the classifier is heavily biased towards false positives it would still be massively useful as the main point of Larsen's method is to increase the signal to noise ratio when searching through a batch of rocks in the microscope![]()
What's funny @Sam Zeloof is that your second-hand machine is WAY less scary than the one @Ben Krasnow got reported for![]()
@Ben Krasnow did you make the gingery home workshop machines, or am I remembering this wrong?![]()
It is my very future goal to do automated scanning for large fields of potential micrometeorites and then sort them out automatically. make a conveyor belt of sorts.![]()

Although TBH, when it comes to universities "ask forgiveness not permission" is a hard rule.![]()
@me hm I wonder why? I mean hardware hacking in most cases does no involve chemicals that could be considered dangerous or used to make drugs.![]()
or am I missing something![]()
decapping may![]()
/delayering![]()
Ben: if it's ok, when you converted your mill. did you use servo motors.. or steppers?![]()
@alexwhittemore agreed... cabinet x rays are pretty safe. but that didn't seem to make a difference in terms of action on the school's part. also you still have to register cabinet x-rays in most states![]()
Mike, I used the original servos. Tidy upgrade.![]()
ah ok..![]()
hmmm that could be! btw heat decapping curious marc showed a while back works great - but it smells![]()
I was recently exploring how citizenscience might fit into the GIS realm - especially with tons of civic data and satellite data out there for free. Feel like it would be fantastic for local scale environmental monitoring. Other than the somewhat steep learning curve, it would be a good way to introduce people to CS. Any easy tools out there? I know NASA has a couple of online interfaces to produce timelapses of an area.![]()
@Sam Zeloof What was the ultimate outcome? I was lucky to live in an extremely hands-off corner of campus where just about the only thing you'd get nicked for was throwing stuff out the window, which the administration looked down on VERY harshly.![]()
biohacking too![]()
I hadn't heard of Gingery home workshop. Looks cool.![]()
@Sam Zeloof but then, don't you now have a lab on campus you could stuff it in anyway?About Us Contact Hackaday.io Give Feedback Terms of Use Privacy Policy Hackaday API
