I’m glad you liked it. I was a bit surprised mine was as popular as it was. I’ve been reading a lot of “One fish, two fish” lately so it was a pretty natural association…
I was a bit frustrated that I couldn’t come up with two more good lines to finish it. Was trying to work in the tattoos or something but couldn’t make it work.
I was hopeful… Aw well.

Unfortunately, as it turns out, chicks are diamagnetic.

Yes. There was no question of whether the SPI port was connected to the display - the only question was which lines of the SPI were used and which weren’t. Given that a lot of displays are write-only, there seemed a fair chance that the MISO line, accessible on the ISP header, might not be connected to the display.
But as it turns out the MISO line is connected to the display’s reset line. Oh well. I guess it’s back to QFN soldering if I want to hack this thing.
The reason I thought the SS line would be free is ‘cause when you’re programming the ATMega you wouldn’t want the display to think you’re talking to it… So I would expect some other ATMega I/O line is being used for the display’s slave select, and thus the ATMega’s SS line is probably free. 'course I could be wrong. Could be they’re programming the boards without the display connected or something.
Is the display wired to the SPI port? If not then I could wire up a pushbutton to that - assuming I can find a place to put a pushbutton. :) If nothing else I’d expect the SS line is probably free…
Personally I’d rather have the simplicity a good old fashion button or two, if there’s some input added to this thing in the future. But yeah, touch sensor would be a cool alternative, and possibly more compact.
Neat. Seems like a good compromise given the constraints of the design. Are there any other additional I/O lines accessible internally? I feel like a device like this really needs a pushbutton or two, if I can find a place to add them…
No public wish lists :(
