So long tank; fun while it lasted

      No Comments on So long tank; fun while it lasted

So it’s been A LONG time since I wrote here.  This will probably not make sense as it’s been ages since I played about with the tank project….

The tank project was fun while it lasted.  The final state was:

  • Turret rotated – this was done using another stepper driver chip.
  • HTML/JavaScript interface kind of worked
  • Including touch!

I carted the tank into the office and had it driving around.  Pretty cool, especially with the webcam.

But there are/were a number of problems:

  • Battery life was dreadful. 15 mins if I was lucky, on a decent 7.2V RC car battery.
  • This was down to the high drain of the motors combined with the relatively high drain on the BifferBoard with WLAN gear, etc
  • And the crappy 5V regulator didn’t help.  It got VERY HOT (burn’ya hot).
  • My HTML/JavaScript abilities are not up to the task of doing things nicely.

And, mostly because I’m somewhat bored of “modern software development” the Linux-in-a-tank project is shelved indefinitely.  I can’t reommend the bifferboard’s enough, however.  With all the attention on the Raspberry Pi, it’s easy to forget these little beauties.
