Sanjit's Summer Project list

This contains a bunch of cool projects that I think are summer-worthy.

Is the sourcecode available somewhere?

Are you sure? yes | no

Edge connectors for SPI - that's my stuff :)

I always solder the pins to those small parts like that, even if they have through-holes.

Are you sure? yes | no

nice project. I was thinking of doing something similar for the 1kBit challenge. But so far there is not enough to design it. Now I had to think about wether my project will be different enough to yours. But this is a nice additional challenge.

Are you sure? yes | no

I want try make game console with attiny85 + 4x5 led matrix and use RESET pin ADC and 2 ..3 buttons ... with more memory usage, can be more hardcore. Digispark is good for this because can be reprogrammed with disabled RESET :)

Are you sure? yes | no
