Shorted it out? … Or did the excess voltage on the super caps and heat from soldering burn it up when you soldered it back. Either way, your super computer has a bug in it 😀
Losing one LED is only just over 1% drop in "processing power", so I wouldn't be too concerned about that. I imagine gluing the LEDs will help with the reliability, since the joints won't be experiencing as much stress from movement.
I really should get around to finishing my supercomputer project. Bought a huge pack of the LEDs and started designing the PCB, but I got stuck when I decided to change the design.
Originally I wanted to make a modular panel that could be expanded by joining multiple panels together, either linearly or in a square, but then I got the idea of building a buck regulator onto the board to run them at a lower voltage. That would allow a 10×10 grid to use a standard 5V 1A phone charger and not have it running flat out. Or it could run off a power bank and last more than a few hours.
I got stuck because I couldn't work out a nice way to route the power between the boards. Maybe I was thinking about it too much. Rather than having sets of traces running from the power input jumping around all the LED power traces to each edge of the board, it's probably easier to just have unconnected solder pads at the edges of the board to join multiple panels together, then just an extra set of pads next to the incoming power connections that you can use to jump between boards with wires. That way I'm not trying to route thick power traces all over the board.
69, nice!
Wen solar run BTC miner when excess solar?
Julian. Can you tell me how you calculate the fwd voltage if unknown of a led panel? I have several here and would like to build light projects
Um, you UV'd the dead LED!
I wondered what was happening in the shed.
Will the ant miner provide enough heat to keep away the Winter Is Coming freezing the shed?
Super computer lives matter.
Change that LED.
Shed's got that nice 'Worked In' look about it now…cheers.
nice !
