Chumby + iPhone + Android + Mecanum Wheels

Couldn’t resist extending the software test on the mecanum wheel base…video comes later this time…

The ‘quick and nasty’ software files are still the same as in the previous post.  Pure software test only, couldn’t resist the temptation to try it via WiFi on a stock Chumby instead of USB tethering.  As such the hardware frame is a bit too flimsy and the batteries aren’t enough to power the Chumby without brown-out resets.  These will be improved upon soon 🙂

This demonstrates the ‘touch’ (initialize) and ‘swipe’ (move/offset) control on touch screens.  Will try the DeviceMotion Javascript API on iOS 4.2 devices (iPhone 4G/iPad) if I can get my hands on that filth… 😛

  2. I want to give ARM programming a try (PS WinAVR is great for programming AVRs)
  3. I found I have some spare ARM7 LPC2378’s lying around (WTF?) and thought I’ll actually complete my Chumby Speedometer on my car project!
