classic mistake though, i like building things, i like blinky things.
i make keyboards, synths and add ons because that is the part i like.
some of us like making tools, some like making tools that make tools,
or just purely for the fun of making, maybe it'll get used maybe it

for instance i have a TKL keyboard (a regular pc keyboard that you
type on, not a synth though it could be) that has 1 key per GPIO  and
2020 rgb leds made on a double sided board because someone made an off
hand comment to a friend that it couldn't be done, it is pointless
even though i can read 32 keys in one go and the whole keyboard in a
few instructions since hid usb isn't fast enough to keep up, and the
debounce is what limits the speed if you manage to fix the usb,
optical keys next!.

but regardless i made it anyway, and i like it a lot.

the whole one must suffer for the art is fine and dandy, but sometimes
the art is creation of a device. after all if you don't use a
paintbrush and paints, and make your own paint you are not a painter
;) this whole computer thing will never catch on sir!
