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 […]
“Sensor Retouch” touch sensitive interactive instrument which allows to play Water, Fruit, Plants and Conductive surfaces as a musical instrument by your touch. All you need is Arduino and few upgraded touch sensitive sensors, i’ll teach you how to put together everything and let start playing with your new interactive instrument ! A project by […]

Simple project to check the air quality in your house. Since we stay/work from home a lot lately, it might be a good idea to monitor the quality of the air and remind yourself when it’s time to open the window and get some fresh air in. Step 1: Parts and Tools Parts BME680 CJMCU […]
An impedance-meter evaluation guide: identify the real converter, require documented timing and calibration, and separate phase processing from accuracy.
