PSA; fuses / breakers / surge-protectors are to stop your house burning down. They will NOT stop you getting electrocuted. A GFCI will, very effectively. A GFCI has a test button on it (which literally shorts the live rail to ground). Easy option: tinyurl.com/x8znumu9
GFCI's clever; measure current flowing out of live and back through neutral wires and requires them to match almost exactly; any imbalance means some is escaping to ground - maybe through a person! Cuts power within milliseconds of detecting just a few milliamps. Saved many lives
note you can still get electrocuted if you touch both live and neutral at the same time - nothing is going to save you from that, frankly - but it's much more common for a hot wire to flow through you (or e.g. a grounded metal case) to ground; tripping the GFCI (a.k.a RCD)
My main point is you can just buy a GFCI / RCD socket splitter or extension cable (make sure it actually has GFCI) and plug it inline with all the crap on your bench and just forget about it - it literally might stop you getting killed by some cheap thing you bought online.
Running code on Raspberry Pi 3A VPU🥳. The VPU is a managment core on the Raspberry GPU, trough the mailbox interface its possible to execute code on it. Here I toggle GPIO2 directly from the VPU, the CPU just idles in Linux that moment :) Free realtime core yay !
Tidied up! - this is "pristine" by local standards. So satisfying I've scheduled a repeat session for 2031. ;-) Also; those "70w" (~30w) 12v white COB plates ($14) have very thin profile, great on manfrotto/gooseneck/coathanger as floating work light, doesn't block monitors
if you run them at a sensible (and still bright) 50% power they don't need heatsink, total about 2.5mm thick. This is my normal line of sight - the led plate fits between the bezels of the adjacent monitors
I remember seeing an interview with @bunniestudios when he mentioned the Chumby tchotchkes and what a time-sink they were; looking at them now I wonder "what were they _thinking_?" (retro shout to @xobs who worked on the firmware) ..Last thing in my house that runs Flash!
