So I started designing the #LoKiPad by basically making a cheap clone of the adafruit nanopad, that @todbot used in a project. I removed the mechanical keys and just used 12mm buttons instead. Then I sold my pocket operator and thought, I can just do some changes and so I ended up here. I guess there's a hole in the universe for mechanical keys on pocket operators now :) would extend the PCB size a lot, too.

May I present, the next version of the #LoKiPAD - this can be a lot of things, but hopefully something musical. 25 buttons, 25 LEDs, Display again and one encoder.

Oh yeah and I still have to route it, hehe. Just 200 and something wires.

for no other reason than "because" I soldered remaining 3 LoKiPads

having some fun with midi controller code I found for adafruits macropad. Just had to change a few pin definitions.

Sorry for the breathing noises!

Found something to try on my #LoKiPAD - wait did I ever use a hashtag for that project before?

I mean I could also try to combine these 2, just need to figure out if I can add I2C to any left over pins, if I have any :D

This Sunday I'm taking things slow, allow my brain to rest. So why not document - as in move things in a folder - and upload stuff to github :) Happy hacking everybody.

got some nice resonance going here, definitely enjoying the lokipad so far, after the hick-up with the LEDs. I want battery and an amp now :D #MacroPadSynthPlug is a win :)

ordered another run of LEDs, more 12mm smd buttons and a second display just for fun and maybe because I've soldered a second pico to a pcb to test the pcb for shorts.

PCBs arrived this week and just today I got almost everything else. What I didn't realise was that I ordered SK6812 3535 LEDs instead of WS2812 3535 LEDs.This meant I had them 90 degrees off on the board, didn't realise that and swapped the regulator (successfully) on the Pico first. To remove the LEDs I then basically almost melted down all the buttons, ugh. But they still work (11.5/12). Got the display to run (yay) and sound comes out (yay) and the encoder works :)
