The New Hotness

  • Raspberry Pi Model 2: Canakit Case Reset Button Mod

    Being a Linux box, a Raspberry Pi requires a tidy shutdown, but, because it uses so little power after that, I decided to forego a power switch and just blip the CPU reset line to start it up again. Canakit cases require a bit of flush-cutter hackage to accommodate a crude socket atop the RUN header:

    The switch originally had three terminals, but turned out to be SPST NO with one unused pin. Flush cutters and some hot melt glue to the rescue:

    Canakit RPi Case – reset switch – interior

    The end result looks OK, modulo a few scuffs on the shiny black plastic:
