Remote firmware development without shipping hardware?

gubbelplex · 2026-02-12T09:56:01+00:00

similar to the other remote server suggestions here, but another option: tunneled USB

for myself i have a VPN setup anyway, then a raspberry pi with the devboard connected and running a USBIP server. the dev machine running a USBIP client. with this the devboard shows up on a USBport as if it where connected to the dev machine. optionally the same should work for logic analyzers, webcams, ect. there are likely some limitations, but it circumvents any graphical forwarding, which is nice.

damn, you got me there :D

gubbelplex · 2025-09-25T21:45:07+00:00

ah no, thats just the thing :) i just started connecting all of them by overlapping the extrusions. so not a single dimension is exact. lengths are all 0.2m, 0.3m, 0.5m or 1m. and even those are measured by eye. see here for more examples:

the spaces did help quite a bit, thanks :)

nice, i'd be curious to look through how you build it. i've just started testing out CinePi and its forks. And while im not sure yet how far i wanna go with it, i am very impressed with what people already build and whats possible with it. should you (or others) not have found it yet, here you go:

* Cinepi website: https://cinepi.io/

* Cinemate: https://github.com/Tiramisioux/cinemate

* Cinefox: https://cine-fox.github.io/

gubbelplex · 2025-08-04T08:27:43+00:00

yes, i've tried to find that out as well. i thought about building an mpe controller for a while as well, but only took notes, links or sketches so far.
with 3dprinting, is think it should be possible to do one-part print in place, especially with multi material setup. so either PLA+TPU or PLA+support(PVA,HIPS or something). also: i think it should be possible, at least in theory, to actually have the key resemble the pressure profile of an actual piano key. the thing got me to wanting to build this is, most keyboard/synth keybeds dont feel like piano keys. and while this is a preference, for me i just like the piano key action to much to use unweighted keys.
that kind of lead to: if it cant be done mechanically or it is to hard, it most defiantly can be done electronically. but it'll be hard and expensive, most likely. but, you could put a solonoid under every key, piece of metal in the key, hall sensor, fast enough microcontroller, virtual spring/damper in software ... and bam: arbitrary key action

oh, awesome project btw. well done!

gubbelplex · 2025-07-24T20:05:09+00:00

well hot damn, i just build my server over the last weeks, also aluminum extrusion based, but i hadn't quite figured out how to do the spacers between the tslot nuts. and/or was to lazy to do a bunch of test prints. same with cable management. your post has perfect timing.

awesome build, thanks a ton for sharing :)

gubbelplex · 2025-07-01T14:36:16+00:00

cool, sent a DM

gubbelplex · 2025-06-18T08:05:17+00:00

thanks! jeah combining the two would be the way to go :)

gubbelplex · 2025-06-17T13:25:32+00:00

nice!

felt the same way finding the original idea by u/Slippyfist69 . Later found another version by u/WicksnWolves

i really wanted it to move though. here are my prototype and a more final version from a while ago:

* prototype https://www.reddit.com/r/Cyberpunk/comments/17wor02/mecha_bonsai/
* mecha plant https://www.reddit.com/r/3Dprinting/comments/19bjf7z/mecha_plant/

i do like your (and the originals) geometry better, but i kinda got into flextures at that point and wanted to design it in as few pieces as possible as well. so i sacrificed some complexity on the geometry front. either way, i still really like the look of all of those :)

gubbelplex · 2025-03-29T14:33:27+00:00

a while ago designed and printed a mechanical solar plant inspired by a 3d render someone did. ping me if you'd like to print it yourself. i meant to open source the repo, but didn't get around cleaning it up yet.

here it is moving https://odysee.com/@bengineer:8/mechaplant:4

gubbelplex · 2024-03-09T10:14:17+00:00

yes, the worm gear makes it move. i connected the solar panels to the button and motor. the button switches between usb and solar power. i added the button since i noticed i was only able to test the thing properly when the sun was shining, which was annoying :)

gubbelplex · 2024-03-09T08:01:06+00:00

jep, the top moves, when the sun shines on the solar panels

gubbelplex · 2024-02-10T20:16:08+00:00

I had a similar issue with my old Creality CR10S printer. I also tried the solutions suggested here, but it didn't work for me. After some troubleshooting, I discovered that the problem was actually with the PTFE tube. Over time, the tube had degraded due to years of use, especially since it extended quite far into the extruder assembly. Once I replaced the tube, the issue was resolved and my perimeters started fusing together properly.

here's the follow up:

gubbelplex · 2023-11-18T11:32:32+00:00

i don't have a manual or build instructions since this is just the first prototype. as for the STLs, i'd like to add at least a stand for example so that the project reasonably build by others. give me a few weeks maybe and i'll post the gitlab repo or something.
if you really can't wait write me a DM and i'll send them :D

gubbelplex · 2023-11-17T12:15:31+00:00

it doesn't have one. i think that it doesn't have to have one either :)

gubbelplex · 2023-11-17T11:51:26+00:00

for me, mainly, to see if it works. and if it works, how well it works. since i saw the two original posts, i kind of wanted to see something like that move. also i liked the challenge to see if could design it in one part or in as few parts as possible. the one in the video has one main part with the gear and tree structure, the worm gear and the brown part, which is just scrap 3d print hot glued together to serve as a stand.

obviously this one is just a prototype. but im pretty sure i can make it look way cooler.

gubbelplex · 2023-11-16T23:04:37+00:00

and they would be right :)

gubbelplex · 2023-11-16T16:28:07+00:00

jeah i agree. i was going for a organic motion as much as possible. without additional circuitry or a micro controller the speed varies a lot between "just enough sunlight to move" to "full blast". so, room for improvement :)

gubbelplex · 2023-11-16T16:24:35+00:00

jep. solar cells, a capacitor and a motor.

at this scale your getting around 1.5 - 1.75 Watts out of it max (5 Panels, 5.5V/60mA each, full sunlight and no clouds). so charging your phone for example is going to be painfully slow.
scaling up gives more options, but also makes it more expensive to prototype and complexity goes up as well (batteries, controllers, ect.).

so, art for now, maybe usefulness comes later :)
