#lokipad — Public Fediverse posts

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.

The project that inspired all this: https://www.youtube.com/watch?v=kLwP-vyvtLM&t=19s&ab_channel=todbot

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

#LoKiPAD

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!

#LoKiPAD

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 :)

#LoKiPAD

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.

#LoKiPAD

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 :)

#LoKiPAD

After a friendly nudge on the problematic name, I'm now calling it LoKiPad, just because it's low-key and a key-pad and I don't know it's a project not a product thankfully :)

#LoKiPAD

Having fun putting together a "ghetto" version of the adafruit macro pad, just because @todbot wrote such cool sound stuff for it. I want to recycle some components and this is fun to design till 3am apparently.

I'm integrating his macro pad that uses the qwiic port for audio out and midi-in. Using up some simpler parts like 12mm buttons, 5mm neopixels and I might have ordered a 7-pin OLED display. On the back is a RP2040 PICO.

Need to remove some through holes.
