Home made GPU escalated quickly [video]

Very cool project.

A great advice one gets at around minute 9 is to place footprints for anything you consider remotely possible or that you'd like to test. You can always leave them unpopulated and the tradeoff between area lost and time lost is usually worth the area, especially in the first iterations of a pcb.

So much in there: so much hand-soldering of SMD, the way he made an SMD resistor bridge to bodge his MOSI/MISO mixup, using the Bambu 3D printer as a test harness (with pogo-pin attachment) to test his "blades"…

(I thought he was going to end up with R2-D2; the way the design was going…)

Im curious what FLOPS and per CPU bandwidth this has. It might be okay at running compute intensive shaders!

This is great. It somewhat reminded me of Steve Ciarcia's build of a Mandelbrot-generating supercomputer from around 1990. That was also made from microcontrollers (Intel 8052 in that case).

The determination to pull through a project of this scale is mind blowing and the joy is contagious.

@3:10 “you need to consider 99.9% of the power is converted to heat” uhm that would be quite an efficient heater you designed there!
