Here's a video of the Z axis lower limit optical detector in operation. Upper is similar. On the lower, I had to swap the 3-pin connector to the outside, else the router base plate would hit it on the way down. I made the interrupters from 3/4 x 3/4...
Update: I added that stubborn LibreOffice pie chart at the end ;)What does it take to be a winner? Getting an entry in early sure helps.I think projects with pictures, videos, and clear details, look like they get more attention.Here is the competition,...
A new and improved spreadsheet is now sorted by project, instead of by contest, making it easier to sort and analyze (no more double entries!) Get the spreadsheet, it looks much better. Download the new one here. It has presorted sheets for most Skulls,...
Friday, 13:25, 02/12/2022 - Yes, "02/12", it took my two days to finish this Project Log since I had to rewrite it time and time again.At first I thought this was a waste of time, but after doing this, I feel like I have a better idea...
As I found in the last post, the isolated UART bus daisychained through the Tesla modules is running at an odd frequency, 612,500bps. This is problematic as it is not a standard PC baud rate. I had an FTDI board lying around so I had a peek at the datasheet...
Here's an electrical schematic. It really is very simple. I wanted to have another one or two LED rows, but I want separate pwm for each one and the servo library eats up two of my pwm pins. Oh well, four will still look cool.I have been making the various...
Today, the NeuroBytes project takes its first baby step into the 21st century.Okay, ignore the extremely sketchy construction techniques. It's an STM32F0 Discovery board, chosen due to its extremely low cost (under $10) and built-in ST-LINK programmer....
The first step was to build a prototype as a first PoC, to verify that the concept works (it adds up on paper, but generating electricity from microbes living in moss is incredible!). So I went to pick up moss nearby and built an experimental setup similar...
The most important component of the profiler is the PAR sensor which is using to measure downwelling irradiance at the surface and through the water column. In order to measure downwelling irradiance the sensor must measure light across the entire upward...
Saturday, 15:08, 26/11/2022 - This is a bad idea. "Why a human-sized mech, and not a exoskeleton?" Well... Sigh... Because the biggest limiting factor of any exoskeleton/power-armor/exosuit is the squishy meaty "pilot" inside of it. The machine...
From everything that was learnt from the hardware development a real / custom actuator had to be developed. After some research the best/easiest solution for me was the 3-Phase driver DRV8305 paired with 6x N-MOSFETs and the PSOC4 Processor. ...
Now it's time to assemble the driver and LEDs in the case. First, I dismantle the original parts from the case. Eight screws in total. Six screws for the LED panel and two screws for the controller.However, I still had to solve the problem of audible...
OK, so I've start this project before submitting it. Best bring it up to date...Firstly I got myself a beefy heatsink (one that was supplied with an AMD Phenom2 I bought ages ago) that would fit into the enclosure and drilled and tapped 2 holes for 2x...
The tedious part is mostly done. Let the fun begin! I now have a robust system for monitoring. Basically I have a data-stream running in a MQTT-topic. I then run mosquitto_sub on that topic with '| tee log.json' on a pi which gives me a nice log. For...
Everyone respected my hacker alias and called me 'crip' when I arrived...even got a nametag: "Crip Lishus" - hellyeah! (Given names are so boring and prescribed. It's nice to reinvent ourselves and our identity to match what we like and...
