Thanks for the response I'm using an acceleromter for the first time and trying to understand how to calibrate it also! I wish I could be of more help but I'm still learning myself. The gyro seems like a great idea though
I was also going to suggest if you have a bunch of old plastic container tops lying around you could try using those.. and save a bit more $$$ (Noxzema tops for instance, a small vicks vapor rub top, and something that could fit between them both) thats if you have the tools to cut them approriately
