I have also made the OSD inform Watt usage and mAh with one sec resolution, the fly timer start when the current use is over 1.2A or what ever level I set it to.īut what do we need a timer for ? when we have an accurate realtime mAh display ? With the microcontroller I use it is possible to get full range of 68A and 0.1A resolution. ![]() On one side the hi resolution current sensor, the other side a lineary powersupply strong enough to handle the OSD and GPS and even small can and tiny TX module So a total of 40MIPS are executed here, nice nice !Ī screenshot made in low res - Real fligt top speed of my 2m stick 213km/hrs (132mph) 213km/hr video clip, check the soundĬurrent sense is done with this tiny board: I use a two chip in parallel solution, one AVR AtMega88 is the OSD and one AVR Atmega168 is the serial NMEAĪnd analog and txt setup controller. Here is my OSD design hardware version 2.05 from 2008 Trouble Shooting, FAQ at the bottom of this page Then you will know what this OSD project is good for, see bottom of this page for VIDEO clips ! ![]() (with GPS height and speed) for model RC planes ![]() OSD, On Screen Display for RC planes Start page
