I made a little LED Matrix and everything went wrong

I designed this matrix 5 years ago and finally took some time to assemble and test it. All went wrong but I manage to make it work anyways. ...and it's bright!

“I put it in a box and forgot about it”. Hey, get outside of my head! 😂
-
every time, it's like a mirror of my own life. As always, thanks for showing every bump in the road. Much love from one geek to another. 💜

A human pick and place machine is a thing of beauty!! :)
-
Very Cool! See you at Maker Faire!
-
Why i like Jlpcb over pcbway isnt so much the 2 vs 5 dollar, but the shipping cost. Somehow jlpcb seems to have cheaper shipping options
-
I used these same LEDs in a number pad PCB project, and they were a hassle. The top plastic layer would always detach from the LED, and they were so hard to solder on properly without rearranging multiple times. If you're going to want to add RGB to a project, consider getting bigger LEDs haha.
-
Handy hint when bit-bashing WS2812 protocol - you can usually leave gaps between bytes, varies with exact part but tens of microseconds is usually OK
-
I made a 8x6 version of this and had JLCPCB assemble it, it doesn't melt, but I do put heat-sinks on the back because they do easily reach 70-80c
-
Hah, I did this soldering with a 6 leg without a microscope and it was a nightmare! I now own 2 scopes. Lol
-
I really should find a use for that string of ATTiny10s.. that I’ve also had in a box since 2019 😂 BTW USBasp does TPI quite nicely.
-
The thing with that board is that it is so small that practically, and fortunately, everything is next to everything else allowing for many opportunities to have "happy accidents" LOL BTW: Funny thing is that I was watching Bob Ross' channel painting when your video came on and I thought I was have a "Happy little brain fart" when you cut that video footage in.

At least you're in good company with the rotated SAO header, the SAO that Digikey put in the swag bags was like that too. It took an embarrassingly long time to realize it was a sideways 'D' and some weird boxy smile or something.
-
I love it !!
-
Great project. I tried using those little things in a project before I had a microscope and never did get it working. I ended up making a new board and using the next bigger size. After seeing this I may go back and retry it.
-
If you're using the attiny10, you can use unused peripheral registers as additional memory. Clever trick I found out a while ago
-
Very cool
-
If there is no space for buffer for 25 RGB pixels, then you should try to calculate RGB values on the fly. Or do it in group of 5 pixels.
-
Miss You !

yesterday found tiny 8x8 rgb led matrix, 25 x 25 mm. with esp32 $8, only leds $4+. i have idea to make rgb cube
-
I love the idea of mounting the microscope to the wall using that monitor arm! Desk space is always at a premium and then you also get the benefit of easily moving the scope to where you need it. What model microscope is that? Is it common that they have mounting points like that for a wall mount? I have an old cheapo one that only has a screen and is monocular, so looking to upgrade to a similar setup as you have here.
