This sketch is an Arduino program which acts as an simplified hardware I/O server using a simple readable message protocol. The intent is to provide an easily modified and extended real-time embedded hardware controller which can interface easily with a non-real-time client running on a laptop or Raspberry Pi. The following documentation was extracted from […]
I got my son a tiny whoop indoor FPV drone for Christmas, specifically an EMAX Tinyhawk II. We’ve had fun creating small obstacle courses in our basement, but one thing was missing – a timer so we could compare flight times. This instructable (my first) is for a drone gate with an automatic timer that […]
Recently, I decided I would like to attempt to make a passcode lock with my newly acquired Arduino Uno, but all the tutorials I could find made use of a modified keypad, something that not every Tom, Dick and Harry has lying about. I therefore decided to set out and make a version using only […]

Do you ever find it a hassle to manually level your 3D print bed every time you make a print? Even seasoned 3D printing pros need to level the printbed after every couple prints. We’ve created a device that helps tremendously improve this procedure. This project, codenamed OmniLevel, helps you level your 3D printer bed […]
I was strolling down the candy aisle at the supermarket and there it was: the PEZ dispenser, conjuring up sweet (literally) childhood memories served up by my favorite cartoon characters in squarish sugary pellets. Then, all of a sudden, an LED went off in my head. PEZ meets Arduino. In this age of over-automation, where robots […]
