So, does it look like they’re doing the same thing you were hoping to do?
Yes, looks similar
After taking a second look at the photo, I noticed they’re using (more expensive) tantalum capacitors instead of electrolytic. You can get tantalum caps in the same values that are on my panels with package height of 3mm, vs 6mm for the typical electrolytic. Doing that sets a new low bar for overall height on the back of the panel.
BTW, I’m working on my own wearable panel project, and I gather you’re working on your next iteration based on some of the questions you’ve been asking. If you want to trade ideas while we’re both working on similar things, let’s do it, maybe in a new thread (I’m too tired right now to figure out the right thread to post to…).
I want my project to use P2.5, maybe P3 panels, as I want to create a diffused look - hiding all pixelation - and the fine pitch allows for the diffusion layer to be thinner, making the wearable overall thinner.
I like the idea of using a flexible panel that can conform to the shape of my chest, back, or the shape of a backpack and not stick out so much. I haven’t actually tried flexing any flexible panels though, and don’t know how realistic that is. Maybe the flexible panel needs to be attached to a rigid rounded frame. I haven’t found any P2.5/P3 panels that are easily purchasable with delivery to the UK yet, plus I haven’t had a need for them recently, so I haven’t ordered any yet.
Another problem for flexible fine pitch panels is the minimum size. Looking on Aliexpress, I can only find 128x64 P2.5 flexible panels, 320mm wide, and that’s too wide for my purposes (I’d like to make this look as much as possible like a logo on a shirt, not a billboard).
There’s another option with a high cost and high minimum, but good to know that someone’s at least making 96x48 pixels P2.5 flex panels, 240x120mm. My ideal at the moment is P2.5 64x64, but 96x96 might be OK if curved enough so it doesn’t stick out away from my shirt. I got a price list from this company, and they also have the 240x120mm panels at ~$50/ea, but not as easy to order as Aliexpress, and I haven’t seen if they have a minimum: SHENZHEN UNIT LED CO.,LTD-LED Display Lighting Manufacturer
I just ordered one of the 160x320mm panels, so I’ll at least have one flexible panel to play with. I got this one which cost a couple bucks more but seems like it might come with the flexible frame, where the other one I linked doesn’t(?). (Took a while to order as my bank decided my ~2000th Aliexpress order might be fraud, though the ~1999 before it were all fine)
I’m also not sure on what scan panel to use, to get the right brightness. The P2.5 64x64/32 panel seemed a little dim to me at full brightness, but I was working in daytime with thin curtains drawn. 2x P2.5 64x32/16 was better. I think you posted already, but if you don’t mind reminding me, what brightness setting are you using in the clubs, and what scan rate are your panels?
Also, have you had any problems getting through security with your panels? I could see depending on the show and venue getting a hard no to bringing even a small electronic setup to a show. I read something about someone bringing macetech LED shades to a show and security making them check them for later pickup.
