STEM Turtle
| Links:
Designed in KiCAD, this AVR training board includes an ATMEGA32, live control via laptop/android phones, many sensors, motors, and RGB LEDs to make STEM learning fun.

It's here! ππ Gold and green turtle!
Looks quite good too. Except for the serial number that some buffoon at the fab thought would look good if placed smack dab in the center π₯Ή pic.twitter.com/Ad8yJccrPf— Jithin B.P., Ph.D. (@jithinbp_) May 30, 2025

Why shouldn't it crawl as wellπ#stemturtle https://t.co/keMataoRNf pic.twitter.com/5VqOmDp5Z7— Jithin B.P., Ph.D. (@jithinbp_) June 13, 2025
Made a little rotary sample holder for the missus' PhD work. Pogo pins+half a spring from a pen.
Hollow shaft stepper motors are awesome - Won't have to drill another hole in the EM shielding, and the wires will cause minimal bother during rotation! pic.twitter.com/stQW91wh0n— Jithin B.P., Ph.D. (@jithinbp_) June 13, 2025
