I recently discussed with some friends about sensors to record jump heights and hang time when kitesurfing. They are really expensive and requires to wear a phone in a waterproof case. As it is a useless sensor and I just wanted to have some fun: I tried with a cheap sensor, an ┬ÁC, and some EEPROM, no need to be accurate to the centimeter…

As a part of my future home automation called NoteRF, I need some devices other than a Raspberry Pi grabbing weather and pollution data from the internet: I designed a PCB and throw some lines of code on it.
Currently, the devices are only sensors, but I plan to implement some actuators later. Everything communicates wirelessly with the help of HopeRF RFM69hw, I will write something on the PCB and publish them as soon as I have the time to do some minor corrections to the Eagle files.
