I made another digital chaos, does it works? I know it is missing the radio reciever circuit, that is connected through designated connector. The board has an emergency beacon in case of getting stuck somewhere or power failure, additional research is needed for the frequency permitted for this application (the frequency on the project is permitted for amateur use in Estonia though). I added .zip compressed .pcb file from ExpressPCB program used to do it for better overview of it. I planned it to be a remote control vehicle to dispatch for longer periods outside, so solar panel for charging is planned on top of the device. The oddly placed pins are for LED board from some soviet TV control panel. The schematic was found from internet and is modified a little bit.
