New distributor

The weekly Sparkfun new product post is approaching so I checked their new product page in anticipation ... well, they sure look familar!

So we can now add the magnificent Sparkfun Electronics to our list of distributors - look for HUB-ee wheels in their robotics section.

Now back to work - We are developing some new accessories for HUB-ee wheels and making good use of the tutorials on using the Arduino IDE to program ATTiny MCU's.

The ATTiny 44 is nice and small so it will fit on a PCB inside the HUB-ee alongside the motor driver IC where it can read the sensors, listen for control signals (I2C or a servo pulse), pass them through a PID loop and set an appropriate motor speed.
