It looks like the label printer is going to be key for some remote control functions.  

This is a really trashy label printer, but it was the cheapest.  The labels don't stick to anything.   The resolution is real low.  The refills are a small fortune.  

The motors are still browning out, despite using a lot less current than the 1:75's.  It could be the wire gauge.  It could be cold weather causing parts to bind.  The CPUs still aren't browning out though.

The biggest problem is the encoders drifting.  It seems the 8Mhz atmegas aren't fast enough to catch all the pulses.  The thing will have to move to faster microcontrollers, but fortunately, it's a lot easier to create a single wire bootloader for a PIC than an atmel.
