It Works!
I had neither Arduino nor batteries. So I made do with an atmega168 with an Arduino bootloader burned and connecting to a power supply with the servos running off the 5V regulator, which got very hot.

Homemade Arduino
This is a fully Arduino-compatible setup based on the Arduino breadboard except with a USB to serial converter and an RS232 level shifter instead of the FTDI chip. I used the parallel cable I’d made previously to burn the bootloader, then I was able to program it and to communicate with it via USB. This was all done using the normal Arduino software on Linux.
