well the avrdude code is based on libusb 0.1 whereas termux has 1.0 and it's pretty slow to code over tmate.io on a phone; i think it makes more sense to program the arduino elsewhere and use a serial interface to preprogrammed code on the phone for now. There's an example in c and python for serially interfacing with arduinos via libusb at https://github.com/tytouf/libusb-cdc-example . so that's the essentials :s :s :s i think it makes sense to acquire a power supply next to make the motors run, but i'll slow down now we'll see how it goes. a day trip today for this might involve: - visit cricket and put a data plan on this phone, or get a phone anywhere - get a power pack (ideally solar) to run everything - get bare wiring for the power pack sufficient to power a motor - get general hobby wiring and wire cutters and optionally a soldering tool - get party balloons - get some prototype construction materials, umm i guess: twine, duct tape, hot glue, some rods - get hobby wiring and optional soldering tool now, i have a toy fan and a servo gimbal. this might not be sufficient to move something around in the air :s continued work seems presently conditioned a functioning result :s :s
