A very simple PCB with 48 flashing red LEDs and a power connector.

Dab of super glue on the underside prior to insertion stops the connectors yawing.
pfff, bet you can't overclock this supercomputer!
Pretty cool idea. The LEDs flash at different rates because the resistors that determine the frequency vary slightly. It is basically a comparator, which is the basis for the 555 timer.
I use the BigClive technique to hold my parts in the board and tinning wires and things.
To stop the spillover, 3D print a mask to fill in the space between the LEDS, and block the light. You also may want to put the power connector on the back of the PCB.
This will work awesome, if you catch my meaning, if you catch my drift. 😉😉 Nudge, Nudge. 🤣 I Love it, Julian!!
What a funny coincidence. I've just designed & 3D printed the side panel of WOPR (War Games) for this purpose. No PCB for me, just 5mm holes with friction fit. I'll probably still throw in some resistors to dim them down a bit.
Any idea why it' seems to be impossible to find slow flashing single colour LEDs these days? I find the 1 Hz rate too fast.
Oh, You Dog! You did it! A bit spicy but excellent! You are right to get on (with) the JLCPCB "wagon" and show those youngins just what you're made of! 😀
I think it would be pretty neat, and more organic, if you put a good light diffuser over it.
Temperature is not the issue its how much of it you've got that counts. As you say a bigger thermal mass is what you need, if your iron has a bigger mass than the pad the tip Temperature wouldn't drop so much on contact.
My technique for holding components is to 3D a blank. Do it right and you can hold all of the components at the same time.
It looks like they are coupled – not random. Do they interact?
You use DHL for delivery ?
How quickly the boards arrive after ordering usually ?
Reminds me of the days playing with the LM3909. It was revolutionary at the time! Allowing you to flash LED's with 1.5v.
