This is the supercomputer panel that appears in the background of the weekly live streams on the BigCliveLive channel:-

Thanks to the wonders of eBay being China's electronic component dumpster, a fully factory sealed antistatic bag of 1000 flashing LEDs managed to have quite a high failure rate.
It was suggested that I exchange the faulty blue ones for red ones to show the progressive failure across the panel over time.
The piece of silicone tube I'm using to grip the LEDs for extraction while heating both pads simultaneously, is standard aquarium style silicone tubing. It's perfect for removing 5mm LEDs.
The PCB is single sided to facilitate easy maintenance. Which turned out to be a good thing.
Here are some of the links I mentioned:-

This also keeps the channel independent of YouTube's advertising algorithms allowing it to be a bit more dangerous and naughty.

So far I’ve finished 3 Supercomputer A4 boards. Green, Blue-Red alternating, and pure blue. The flashing pure blue LEDs seem to have the highest failure rate. That figures since I decided I like the blue board best. I’ve seen two modes of failure. One where they are just lights out, totally dark, and one where they are just solid blue, constant-on, but no blink. There were so many failures I started testing each one before I installed it to avoid the need for replacement. Even then there were some that failed after that point. Also many had dangling epoxy snot aberrations that prevented them from sitting squarely on the PCB and those had to be removed and trimmed or replaced altogether. Good old eBay. I Just received a reel of 5000 1206 SMD 470 resistors that I ordered with the hope of speeding up the building process. Not sure if there was a stencil option from JLCPCB when I ordered my boards but either way I have a hunch I’m going to wish I had one. Thought it might save time vs. fiddling with the axial leads. Now that I see how tiny they are I’m not so sure. Almost think it would be worth the time to build a small CNC machine that would squirt a dab of solder paste on each resistor pad. For now it looks like my patience is about to be tested with the manual process. At least the fine end product is worth all of the time and effort. When night falls and darkness is all around, it’s fun to fire them up and watch them go!
Radio is better than TV because the pictures are better. TV shatters illusions.
In the 1960's we had Gay Byrne, Charles Mitchell (no relation), Maurice Doherty rty and Kathleen Watkins on the Radio.
When we got our first black and white TV in 1969 these individuals "looked like" their "Radio Image".
The human eye has a maximum sensitivity to daylight at a frequency of 555 nm and at night this changes to 507 nm.
This refers to a colour of greenish yellow by day and bluish green by night.
So if you are looking at a red, green and blue lamp at the exact same intensity red and blue will APPEAR to be reduced in intensity relative to green.
Please note that the Sun has a maximum output of about 500 nm at the Earth's surface which is bluish green (cyan).
I made a Blinking light computer from your design. A total of 15 4 x 6 panels together in a 18 x 20 frame. Would like to send a video of it but don't know how
Where do you get the boards? Or, are these custom ones you have made? I don't know anything about having custom boards made.

Not happy with color yet, work in progress.
Do these leds go out of sync naturally? If so, what should I search in ebay/aliexpress to get those?
So why are they not all on or off at the same time?
Yup, ambient sound to help me sleep. If I am anxious nauseous or whatever, your videos are a god send if I am honest!
Fantastic content been watching for years now!
You look lovely.
Each time one fails change its colour again, so all failed blues become red, all failed reds become green, greens to yellow, etc.
See if we end up with a multicoloured board or a fairly flat board.
Thanks for making the livestreams. 🙂 Whenever I'm feeling down, I tend to put one on, makes me feel less lonely.
