On the other hand I’m patiently waiting until I could buy those at almost any price :slight_smile:

I’ll see if I can setup a page on my website where people can pre-order modules for a second production batch.

Finally got this working. Very cool. Don’t know what was wrong, but I ran OpenRGB for the first time in ages and the RGB’s sprang into life. The rename script only worked on one LED strip, so I had to manually edit it.

Hello everyone!

Here is a Google Form survey to help me gauge the interest in a second batch of my RGB LED Matrix modules.

Email address to be notified if this batch ends up being ordered. I will not send you any spam or sell your data. If we don’t get enough people interested for a batch, then I’ll email you saying so. Then I’ll delete all the submitted emails.

Note:

Each RGB LED Matrix module will end up costing between $100 and $200. I have not nailed down the pricing yet. It is subject to change if the batch has enough people interested.

Btw I didn’t want to install python, and found I could copy the layout shown in video with these steps in the “Edit shape” window:

For single module, like led-reordering-script.py

  1. Click “Reset” if needed to revert to the starting default horizontal line, numbered from 0 to 288
  2. Click “ZigZag” and enter size “9”
  3. Click “Rotate”
  4. Hold the “Ctrl” key and drag and select a box around every other row
  5. Click “H-Flip” to swap the LED order in every other row.

Edit – after attempting an RGB color wheel, I realized the last two steps are necessary because the row numbering must always increase from left to right, but “ZigZag” reverses the numbering on every other row.

On Win11 24H2, I had to use the Experimental build as well. The stable 0.9 wasn’t working for me.

249

Version 0.9 seems to be very out of date. I still recommend using the experimental build.

250

Is there enough interest for this bach2?
Can we still add ourselves to it?

251

Hello, the batch 2 interest form is still open. You can complete the form here.

It looks like there will be enough people interested for me to order a run of 50 modules.

I can’t recall if I’ve filled out the form yet. Are you able to check for me or should I submit again and presume your form handles duplicates gracefully?

You can either message me your email address on the forum or on discord and I’ll check.

Can I get opinions on this?

Can’t PCBway fabricate the plastic and metal parts, as well, even if the final non-solder assembly is on us?

Also, I couldn’t see pricing info on that page. Perhaps because I don’t yet have an account?

Beyond that, if the opinion you’re asking is, “would we be fine ordering this stuff from PCBway directly,” then I don’t see any problem with it, as long as we have a way to get the plastic and metal parts we need, as well.

I remember reading that for the first run you received some custom parts from Framework - the plastic top shell and the magnetic connector.

I am only interested in getting the final product, not the PCB that I would have no way of turning into a good-looking final assembly myself. So the question is, would that order come with all the parts to get to the final product like it was shipped in the first run, or not?

258

I only get /dev/ttyACM0. No matter which places I put the modules in, one of them works. The other does not. Is there a setting or some magical incantation I should be utilizing? I fear one of them is just not working as I would expect them to show up as USB devices, no?

259

Can you please test on Windows 11?

Do any Penguinistas know: If the kernel doesn’t see my matrix, is there any hope at all of the matrix being alive if dmesg never shows it coming up? There should be some sort of USB device recognized by the kernel, I presume. Meaning: I’m 95% sure. Does anyone have any ideas that I can try?

In short: One of the matrices shows up in dmesg as /dev/ttyACM0. I see this in dmesg:

usb 1-3.3: New USB device found, idVendor=2e8a, idProduct=f00a, bcdDevice= 1.00
…etc…

But I don’t see similar entries for the other matrix. If I swap the slots for the matrices, the problem follows the matrix. I think this means that it’s not powering up or communicating on the USB bus. Are there any BIOS or other settings you can think of that I can try?

Joseph, I’m pretty sure this one is not good so if Linux can’t find it, it’s a goner. So I’m reluctant to go through the exercise. I may be putting in a Batch 2 order; that would give me a spare, too. I’ll continue to debug for the next few days.

261

Probably not…I assume you put one in at a time and one of them prints nothing in dmesg? The only thing I can think to try is flashing the firmware again. But if you aren’t able to get any response from it, I would say it’s broken.
