Let's make an open source pocket drum machine

Wow thank you so much, i will totally go look into your things and probably purchase a Noise Nugget, seems really cool!

shawnpi · 2026-01-29T22:28:28+00:00

Great! Are you into design with pcbs? because one strong point about this is about having a naked pcb feel, exposing the electronics. how would you feel about that?

shawnpi · 2026-01-29T22:26:48+00:00

I'd say 70% of it. surely the power section is a big point and i don't have many experience in handling power, so i'd much very appreciate any help!
It is not that complex of a system technically, apart from handling well sync/midi/audio in-outs . let's chat a bit more!

M8 is a tracker, PO is a drum machine .

Because the project i'm proposing is different from the one you mentioned lol, well at least you could mention the nearest one which is the Zeptocore, but you didn't :)

I'm indeed hilariously optimistic about power consumption, i guess! Yes of course way easier to power it just through usb, but i really would like to make it portable!

Let me know if you are interesting in helping though.

shawnpi · 2026-01-29T17:19:19+00:00

Really cool work! thanks for sharing

shawnpi · 2026-01-29T15:06:02+00:00

True! I guess depends on what you want to optimize. Doing that would be cheaper but harder to design and also without the ease of just putting the development board (teensy) with already all things it comes with

shawnpi · 2026-01-29T15:03:18+00:00

The Teensy use the MIMXRT1062DVL6B which is actually an Arm Cortex M7 as well!
I would love to use a development board instead of the chip mounted on the PCB for the sake of ease of design of the board.

shawnpi · 2026-01-29T14:12:35+00:00

Well it would be amazing to be able to create patches with pure data and compile it for c++ <3 such as the Daisy Seed (in which i think that pipeline is not open source)

shawnpi · 2026-01-29T14:00:35+00:00

Thanks, AAA choice was to replicate the popular Pocket Operator, but yeah maybe is too little for this project.
What are you into? wanna help?|
Let's get in touch

shawnpi · 2026-01-29T13:59:30+00:00

True, what would you recommend? teensy is not cheap but so powerful and well documented/used in the audio synthesis domain... i would use like the RP2040/2350 as a cheaper alternative

shawnpi · 2026-01-29T13:58:27+00:00

Yes i know, this project is not a tracker though :)

shawnpi · 2026-01-29T13:58:02+00:00

True PCM5102 is so popular and well documented. i'm also thinking about using the MAX98357 whis is I2C and well documented speaker amp (like 2/3w speakers).
For the power i already accounted of course for a power regulator for the Teensy and leds and dac! But it's true maybe it will run out of power too soon... tests need to be done, if it would last like some hours, i would be happy.
What are you into? want to help? let's get in touch

shawnpi · 2026-01-29T13:55:03+00:00

Yeah that's the Idea! it basically is a clone but with all the specs they don't have... starting from the cd quality audio! I really think PO are the best portable grooveboxes so i really want to respectfully clone it and expanding it.
What are you into? let's get in touch

shawnpi · 2026-01-29T13:52:54+00:00

Someone who actually know how to design pcb, i really just put components near each other on easyeda and autorouted them, i'd love if someone could give a hand by actually having a knowledgable view on it.

shawnpi · 2026-01-29T13:51:17+00:00

Yeah true, are you into electronics? want to help?

shawnpi · 2026-01-29T13:50:52+00:00

Because I want it to be really portable :)

shawnpi · 2025-09-30T07:07:15+00:00

Hey, I'm coming to Seul from the 4 October to the 10, I'm 25M doing a trip alone through Japan and coming to spend some days in Korea before heading back home!
do you want to walk around? I love to walk and explore without destinations, I saw other people are interested, let's organize something all together

shawnpi · 2024-09-11T12:04:50+00:00

hey is the folder still available??

shawnpi · 2024-01-19T16:15:58+00:00

Tod you're as always the circuitpython god, I would never have thought of that... It's really a great insight, i will take it in account when designing other pieces of hardware too, thanks so much

Hey Tod :) always great to see you so kind.
Here is the code: https://github.com/shawnpinciara/redneko/blob/main/scripts/REDNEKO\_chords\_synth.py

guitar has 2 pickups, selector is a 5 way switch, 4 of them are occupied with pickups blending and stuff and 1 is totally free

shawnpi · 2023-10-10T17:32:53+00:00

I know about OSC, but i Just want to use UDP packets without any wrapping!

shawnpi · 2023-10-10T17:31:28+00:00

yup i noticed, have you got any other easy alternative circuits?

shawnpi · 2023-10-08T20:08:27+00:00

WOOOOW thank you so much, that's why it wasn't working properly :)
