This video shows my new DIY tool for adding a fixed capacitance to any circuit. Way easier than digging through the bin for X value of capacitor. Really handy for debugging or prototyping.
I finally got around to designing and manufacturing my own breakout circuit board for the WIFI enabled ESP8266 microcontroller! This works perfectly for what I need in basic projects.
You probably have never seen this little ESP32 microcontroller- You should and it is GREAT! For all my recent projects this board has more power for less cost than a basic Arduino 328!
The K40 enabled me to do basic laser-cutting and manufacturing right at home during the pandemic. These are the simple mods I did to turn the K40 in to a semi-pro tool at a budget price.
