I made a servo motor with a 3D printer and a 4-legged spider robot.
This whole circuit is the same size as a regular poker chip, but with an added surprise: lights!
A DIY temperature controlled Hot Plate for soldering SMD components.
How to program a through-hole OR surface-mount ATtiny85 chip as a low-cost, low-power Arduino.
How to solder SMD components.
Small BLE Reflow oven controller. It has Type K Thermocouple/Fan/Heater/5VDC input terminals and RGB LED. Arduino compatible.
Build capacitive touch into your next wireless project!
I wanted to test my assumptions before making a PCB for another project. This let me test the one extra chip I had.
Populating Surface Mount Device (SMD) components is much easier and efficient with vacuum tweezers compared to basic mechanical tweezers
A miniature version of a metronome that appeared in Popular Electronics December 1981. (When microprocessors were still expensive!)
