Soaring up to 1350m with my Topmodels CZ Fascination glider.
Another project was added: PPM to Analog Converter
This hardware will convert a standard RC PPM signal into an analog voltage of 0-5V. Mainly intended to convert the RSSI and Link Quality of the EzUHF receiver but can be used for other purposes as well.
