Some notes on flashing tinyprotos (or other ATtiny85 based boards) with micronucleus.
Without disabling reset pin:
avrdude -c usbtiny -p attiny85 -U flash:w:micronucleus-1.06.hex -U lfuse:w:0xe1:m -U hfuse:w:0xdd:m -U efuse:w:0xfe:m
With disabling reset pin:
avrdude -c usbtiny -p attiny85 -U flash:w:micronucleus-1.06.hex -U lfuse:w:0xe1:m -U hfuse:w:0x5d:m -U efuse:w:0xfe:m

Thank you!
Components arrived from Digikey this morning! Not having the final boards, I printed off a paper copy. And found my first mistake.
Apparently SOIC packages come in three different widths. Updated to reflect the SOIC-8M size.
Lesson learned: double check packages before ordering boards. I didn't catch this in time for Seeed to swap out the order, so I've sent another order in. At $10USD for ten boards, it won't break the bank. The old ones will be usable as just plain proto boards anyhow.
These boards are 5cm square, so they're large enough to accomodate a simple circuit in the prototyping area, and small enough to be cost effective to build.
There's no programming header on this board. I'd like to program them through the I/O pins. If all goes well, I'll make a pogo pin rig to do that.
I've sent the boards off to Seeed for fabrication. In about three weeks, I'll get to see if they work or not.
