I used an ESP8266 to build an air conditioning "remote" that I can control with my Home Assistant setup. I was pretty surprised when I moved and it still worked at the new apartment.

I also bought some LED matrix displays that I'm going to use to display information about when trains are due at my nearby station.

There is a wide library of IR remote glue code at

Thanks for teaching me about SPI, I might have a play around and see if I can get that working.

Thank you! Glad you liked it :)

Have fun!

The way I saw it, I'd rather have a memento of the past that I can actually use than one that will sit around in a drawer.

With an adapter you still can use the controller (or you can also use a snes)

Thanks for the tip to turn off interrupts when working with precise timing!

I had a feeling the polling rate was probably to do with the frame rate of the SNES rather than some requirement of the controller. I'll try out a higher polling rate and see what happens.

Yeah I wouldn't be worried about the hardware at all. The only chips on there are two 8-bit shift registers and according to the datasheet at 5V they can run up to 3MHz. You're much more likely to run into the limits of the USB protocol than the SNES controller hardware.
