Thursday, 06/07/2023, 12:40.(I wrote this project log before copy-pasting it here) Anyway, back to DIY electric motors: I can't simply use two 10:1 reduction ratios (which would give 100:1 in total) simply because if I want to reach 30 rpm with...
As Michael mentioned, he somewhat nerd sniped me with the the idea of squeezing a Towers of Hanoi solver in not the Science Fair Microcomputer Trainer. As an avid fan of both the Gakken FX R-165 and the Science Fair Microcomputer Trainer, I could't let...
As the amazing online GPRS Weather Station project continues, we have yet another upgrade to the vast array of sensors with a professional analogue wind vane, kindly donated by Vector Instruments. This device will eventually be hooked into the new, upgraded,...
Full video on this subject (this is literally the script): https://www.youtube.com/watch?v=Psy6lRcdGtk Introduction Old houses, like my parents’ home, comes wired with simple electromechanical doorbells. They’re a simple electromagnet with a metal...
I started wiring up the Memory sub-system board and realized quickly that I needed the display board to show the state of the various registers. I first had to create a backplane to connect the boards into. The backplane carries all the signals...

Days until deadline: 16→InsertImageI still don't have the correct tag in hand yet (ntag203). But today I was able to write an NDEF formatted message to the MiFare Classic tag that came witdh the NFC reader. This was all thanks to the Seeed Studio PN532...
Days until deadline: 13→InsertImageI have had a few productive nights of coding and now have a working proof of concept. After arriving home from holiday at in-laws house I was happy to see the NTAG203 samples I had ordered had arrived while I was gone....
I'm happy to report that I have finished the hardware prototype and have the first full version of the firmware done.→InsertImageThat turns out to be a lot of wires. From left to right is the PN532 NFC reader, Arduino, and breadboard. On the breadboard...
Now with everything built and wired up to the Arduino, I had one last step. I needed to get my PC to share its processor utilization data with the Arduino. I figured I would be writing up some software in C# to do this, but found an even simpler way....
