fun things you can do

I wrote a python generator for KiCAD for this, I hope you did too.
if this is the x-axis, it has a y-axis too...

Raspberry Pi is bringing out new silicon, the RP2350.

At boot time user can select whether she wants it to be a dual-core RISC-V or a dual-core Cortex-M33 ARM.

https://www.raspberrypi.com/documentation/microcontrollers/silicon.html#architecture-switching

Silicon has become cheap as dirt so they decided to leave 50% of the CPUs dormant.

Oh, and there's no FPU in RISC-V mode.

But it comes with a glitch detector.

Still it's a performance boost at a similar price. But I challenge you to break down all those barriers: get all four cores running simultaneously through glitching and use the FPU!

fun fact: the website still contradicts itself whether the FPU is single or double precision.
