Removing undesired reflections/spots
Log from Open Indirect Ophthalmoscope
Hey all!This is another project log to update the latest developments of OWL (Just in case you forgot, we call it OWL because, well, Open Indirect Ophthalmoscope, OIO).So, since the last time I made a log, we’ve been working on--making an elegant GUI...

proof of concept using Fischertechnik
Log from simple pick-and-place head
To see if the idea works at all I started with a quick build based on Fischertechnik and some hot glue. The small Fischertechnik gear "Riegelscheibe Z20" fits perfectly on the 4mm part of the Luer connector. It is actually a gear with 20 teeth, modulus...

DC27 DOOM SAO - Hurt Me Plenty
Log from AND!XOR DC27 Badge
We’ve been lucky this year to have Cr4bf04m on our team, aka LonghornEngineer, aka Parker Dillmann. He shared our goal of the DC27 project to make the badges free during hacker summer camp. Aside from philanthropist backers and generous sponsors (Urbane...

First Experiments - March, 2021
Log from E-TKT: anachronic label maker
Using Arduino mega, communication via serial.Carousel homing with infrared sensor + one missing “teeth” led to inconsistent results and misalignment.Testing with SG-90 servo, but it was too weak to press the tape.

Battery swap - part 1
Log from mEgaTON Radio
So it ends up two of the four batteries I got are dead. Thankfully, I have plenty of enloop batteries around to test. I wired up three to get my 3.6v (4.2v technically, but that will drop as they discharge), and the radio seems to work just fine. I do...

The Jsoknit pH meter
Log from Jsoknit
So now that Jskonit is sort of past the "hello world" (led on, led off) phase, I made a start on the next Jsoknit enabled device, a pH meter. There are plenty of well documented pH meters around and I chose this one as a base project:https://github.com/hephesto/phduinoI...

PIR checkup and Dropbox
Log from Dragon Detector
I checked on the PIR and it is working correctly. To test it, I wired an LED between the module's output and gnd. The LED was going on for about 3s each time motion was detected. I trimmed this down to around 2s which should be plenty to ensure that...

Boards Arrived
Log from RunTinyRun
The PCBs have arrived. I'm not impressed with the quality but hopefully they'll work. Lesson learned No.1: check the minimum silkscreen specifics of the fab house. I did at some point but, changes after changes, I ended up with characters smaller than...

Testing the first prototype
Log from simple pick-and-place head
I transfered the basic idea into one single 3D-printable part and -surprise, surprise - it works! This construction was my first time using FreeCAD for designing a non-trival part. Information about the new part/body model in version 0.17 isn't as easy...

SPI Low Power Success
Log from Wireless BLE Kinesis Advantage (Custom Controller)
So everything went as planned, using SPI the whole loop executes in under 1ms (compared to 8ms with i2C at 400kHz). I didn't even have to set the SPI speed, the default for the nrf52 was plenty fast. Next, I added delay(17) at the end of the loop, so...

Material Progress
Log from Tippy Timer
The battery spring contacts, 9x4.2mm passive buzzers and LED windows arrived a couple of days ago. I was able to test out the battery holder concept and the fit/finish of the case. Here's what I have right now:There is a single M1.7x6mm screw holding...

milling LED covers
Log from 110 / 230 V~ PCB Heated Bed
Yesterday, I was able to mill the polycarbonate LED covers for the heated beds on our mill at Attraktor makterspace. They turned out way better than I hoped. The necessary screws and nuts haven't yet been delivered, but once they arrive, the parts for...

Hardware
Log from Hydroponics control
Things have been moving along a bit slow on this project of late but some progress has been made this week on the circuit design. Primarily this is a NodeMCU board with a bunch of IO associated with it. Normally I would have just copied and pasted...

Installation is a Pain; Flexible GPIO
Log from Garage Security
I totally acknowledge that installation of all the software dependencies and managing configurations is a pain in the butt. Because Pi's are often single-purpose (ish), I think I'm going to remedy this by making Garage Security a .bin file that can be...

Frequently Asked Questions
Log from My Off-grid Solar System Monitoring
When I show my PV system to my friends, they often ask following questions:Q: How much did your PV system cost ?A: The total budget is close to 14 000 €Q: What about the ROI (Return On Investment) ?A: It will take 20 years to amortize the...
