Can confirm, here’s a small BOM:
8x 8x8 WS2812 Matrix $2 each = $16
ESP32 $3
1x some acrylic to laser-cut a case in a makerspace $5
So $24 total. The screen would be much larger than the Busy Bar version, which could be a pro or a con, depending on what you want.
If you need the smaller back screen (I don’t see the use because I would control it from a computer anyways), that would add another $3 or so. The buttons are basically free but if we assume $3, that’s $30 like you said in total.
- shadowpho 2y agono, that's not how much that costs at all lol
- echoangle 2y agoEver been on Aliexpress? I was roughly converting prices from € to $ and adding some spare for tolerance, here’s what I actually paid: LED Matrix: 5 for 6,33€ (that is 1,27€ each) ESP32 C3 Supermini: 3 for 3,56€ (1,19€ each) There’s scrap acrylic at my makerspace so I was guessing, make it 10€ and I’m at 23€ or so. What numbers do you not believe?
- shadowpho 2y agoWho’s doing the case? Who’s doing the buttons? Who’s gonna put it together? Testing? Programming? Flashing? How about handling returns? Packaging? Design for all of the above?
- echoangle 2y agoWell that’s the point of a DIY project, you are going to do it (if that’s the kind of project you want). I wasn’t saying you should build this thing yourself because the busy bar is bad, I was just giving some more data to the original commenter who said you can build something similar yourself for much cheaper.
