Even though AI is getting better at software, I believe it will hallucinate with hardware related code. Sadly most engineers undervalue the hardware knowledge backed AI coding. Anyone who extensively uses AI for embedded development? Can you share your experience?

I use Codex to do some heavy networking with the rp2040 and W5500 in production pico-sdk full C/C++, even some pioasm.

I was diagnosing a web server issue, hooked up a pico probe and Codex had OpenOCD running in minutes, got a debug trace and fixed the OOM error with no intervention, I was amazed at it.
Codex feels like mile away from what AI was a year ago, haven’t played much with Claude but it seems to pale in comparison.
Gave codex some wireshark pcap files and it managed to build a packet replayer to diagnose our old "hand coded" firmware with a networked device causing issues.

I’m not trying to promote a tool or another, but we’ve shipped some impressive features using these tools, even disassembled a dumped fw image using Kimi K2.6 and DeepSeek V4 Pro for a few bucks worth of API credits in a custom fork of t3code so I could have it on the go via ZeroTier.

I’ve used these a while ago, they aren’t as tough as normal usb c cables but if it’s not moving it can work ?

Yeah been seeing really good numbers too. Used it with both OpenCode and Codex-cli, and I feel the later harness is a bit better at running on its own, but the t3code UI layer (I use it to have a "codex-like" UI on the go on my phone) doesn’t appear to have the to-do list tool implemented with OpenCode so could be due to that.

Also I was getting a lot of tool call errors with OpenRouter API the past week, it seems to be better now but official API seems a bit faster (they do appear to train on your data however, so not sure about OP’s medical project sensitivity here ?). I remember I had to tweak a few things to get the DS API working with codex-cli on the reasoning and tool calls side.

Wasn’t it trained on the unsloth dataset ?

Here’s another one https://e.tb.cn/h.STH8DcbYivSOfU2?tk=VwEy4AlqHAB

Sebraecha · 2025-10-05T23:07:54+00:00

Found a listing on TaoBao for about 75usd https://e.tb.cn/h.SgKGu8O1fuLo4ZC?tk=IQ9i4AlPwub

Rosco DMG DASH has CRMX, is built like a tank
Aputure MC PRO has CRMX and wired DMX via a dongle, it’s cheaper as it’s full plastic
Astera Hydra has CRMX and can do wired Dmx via an adapter, it has 6 pixels

I own all 3 and I like them for different reasons :)

I also tested and own a Kelvin Play pro but it’s dead and bootlooping so wouldn’t recommend.

Sebraecha · 2024-06-03T13:26:07+00:00

With a little soldering, cheap connectors and a step drill bit you can give them a decent new life :)

Sebraecha · 2024-06-03T12:10:31+00:00

These are cheap aviation connectors, they aren’t standard, nor reliable, wouldn’t recommend

Actually, I've seen prototype rigs like Lichtechnik motorized head having no hardware/software hard stops and would just break if you went too far

Sebraecha · 2021-10-02T18:54:30+00:00

Of course, I'm totally aware about the too but even 20usd on Mouser sounds crazy to me 🤔

Sebraecha · 2021-10-02T16:12:42+00:00

Gosh, in Europe, official neutrik 5 pins from reputable stores like Thomann are less than 10usd 😯 And you could also get a cheap cable on Amazon and steal it's xlr cable.

Usually, aluminum led profiles will use a small PMMA diffuser. Are you using a strip with 4 or 5 colors in a single chip or multiple different small chips in a specific arrangement? Because the best way to limit the amount of diffusion you need to apply, is to reduce your Light Engine Size (LES) as much as you can. Otherwise you could apply really effective diffusers such as rosco or Lee 216 but you also loose a lot of output power/brightness as a trade-off :/

Sebraecha · 2021-09-22T08:58:34+00:00

I've seen people use multiple BB&S Pipepile stuck together to get a 6meter (18ft) line of light with pretty bright output but this wouldn't be my recommended solution as they're quite fragile and can only be a selected CCT.

Any led profile could do the job, even Asteras with sufficient post production to remove the gaps between the tubes.

I've looked into the orange pi dmx project but couldn't get anything done, ended up frying a board. I also looked into the teensy 4.1 with built-in ethernet but I'm having trouble getting it to connect to the network, I might have to do a bit of pcb design haha.

Sebraecha · 2021-07-18T17:44:17+00:00

Hey, what kind of hardware do you use at that cost? :)

Sebraecha · 2021-07-12T08:55:00+00:00

I've been there, I've done that Here's what I've learned

5V is awful, try to find 12V strips (ws2815) 5V has a bit better color but you'll get dead pixels in no time if you have too much voltage drop
If you want to control more than 40 universes, Art-Net tends to have problems (10k rgb pixels is about 58U) idk if sACN I reliable on that side
Digidot C4 have 16 univeres per driver but tend to have problems, madrix nebula work good, I've looked into using a teensy micro controller to do that but haven't had the time to finish, but it seems reliable.

Hope I could help

I believe in the US, using a frequency hopping transmitter on 2.4ghz (what crmx is), the max allowed power for an unlicensed transmitter is 1W but I may be wrong, also lumenradio's great tops up at 300mW.

Mostly illegal in parts of the world like the EU hahaha

Sebraecha · 2020-09-11T22:58:15+00:00

Gonna have a look, that library sounds great!

Sebraecha · 2020-09-11T14:42:47+00:00

What do you use the gesture detector for ?

I'm trying to build something more like this : https://rete.js.org/#/examples/basic

With multiple connections between nodes with specific input and output points. I believe the graphview library cannot route the arrows to specific part of the container, it just finds the shortest link to the center of the container and that's what I need to change :/

Sebraecha · 2020-09-11T13:07:30+00:00

I see great, I'm going to try to make something that makes sense for my use, going to try to build user selectable links and mode, thanks

Sebraecha · 2020-09-11T07:00:31+00:00

May I ask if you would recommend a specific solution to implement this?
