I am still without a third FSR for my auto calibration Z Probe system! I need 3 because 3 points define a plane and also that is what my heated bed rests on, I have the FSRs installed with a quarter inch rubber foot on top of it as an insulater and it...
PCB Rev 2 is working quite well.I have written the "drivers" (I guess thats the term!) for the Graphical LCD, barcode, Keyboard, RFID and Wifi. All said modules are working (though not in any way cohesively) however mechanically the LCD alignment needs...
I will admit to committing a cardinal sin of electronic device design - I picked the enclosure before designing what needed to go in it. This is one of the reasons I'm designing another hardware iteration, and had a few implications that can be seen...
The first step in constructing an autonomous buoy is to design a suitable-rugged enclosure for the electronics. This enclosure should be easily replicated by anyone anywhere at a low cost point. Here are three possibilities:A 500ml Coke bottle cut...
NOTE: This post is also published here on my blog (more details/photos).Bulk made enclosures are useful when you just want basic underwear on your Pi but what if you need to put something else in there and it won't fit? I've built a Pi enclosure for...
Since the microscope in question was actually a pile of broken microscopes (dumpster find), with just about enough parts to make two working 'scopes, the majority of the work in this project was spent cleaning repairing and re-assembling the optics and...
At this point, "Haptic Feedback" seems more an art than a science.One of the central challenges in this project is the communication of sensor data to the user in an intuitive manner. Now, blind people are often described as having significantly enhanced...
Over the past several months I've been doing a lot of traveling with my PIvena. I've been working on some cool projects at home and then carting it along with me to work to show what I'm working on. With the LCD facing out the PIvena is a little vulnerable...
Both brakes are at least stuck partially engaged. Battery is completely dead (0V) so the car battery was used for testing. Battery needs replacing (new one ordered). Smoke from exhaust is oil-rich and smells like the carburettor needs...
We’ve been a little behind on the documentation train and are trying hard to catch up. We just finished up the docs for FarmBot Genesis V0.6, check em out! Notice that these docs are now hosted on this website rather than the community wiki. Don’t worry,...
People often want to know how much electricity FarmBot uses. Sometimes they’re wondering if FarmBot can be run on solar power (which it can be). Though more often they are actually searching for an answer to this (slightly more complicated) question:...
I am going to use the HRM-2511E fingertip pulse sensor manufactured by Kyoto Electronic Co., China in the prototype of this project. I have worked with this sensor before and I have found it very easy to use, and provides stable output. The HRM-2511E...
I started this project 2 years ago by wrapping some polymorph around a small transducer and hooking it up to a desk mixer. It didnt work great but it was compelling enough for me to keep interested in it and come back to it when i have a eureka moment....
I'll start off with the money shot. It's a 35-key keyboard, probably originally intended for handheld inventory computers or something else used in an industrial setting. Pretty normal and what you'd expect, but check it out, doubleshot caps.Now for...
