/diy/ - Do It Yourself

I'm taking a look at the digispark board here, because their feeding USB directly into two pins on the mcu is interesting. There's nothing about USB compat on the datasheet, and they're using some interesting circuitry, namely those zener diodes on the data pins, one of which also has a pullup.

I was thinking about making a dongle like the normal digispark, but without the massive 5v regulator, and with the dip8 socket like other digispark style boards. I'd make it the same width as the usb plug all the way along since my digispark has too short of a plug to work in my laptop's recessed usb sockets, and I might even ditch the pin headers and just use it for programming dip mcus. I'd call it the digidong. Thoughts?
