[DIY] I accidentally made a Flash Joule Heating reactor and used it to turn pencil lead into single-layer graphene.

So… uh. Long story short, I think I just invented an energy material production rig that can turn biomass (or anything with carbon) into monolayer graphene.

Here's what I did:

Power supply: Corsair RM 750e I found in a junk shop • I manually removed all safety protections (Yes. All of them.)

Electrodes: Scrap copper (just rubbing shoulders together like homies)

Substrate (original): Styrofoam (please don’t do this) Substrate (current): Ceramic tile

Fuel: Pencil lead at first, now burnt banana peels

Trigger: Manual button at first, later replaced by a smart socket that recorded my pulse pattern (I treated it like a rhythm game and saved the sequence. If you wanna recreate it, try the beat from Doodle (Zachz Winner Remix)

Absolutely no idea how I made this. I was just messing around with a junkshop PSU tbh.

In the end, all I really did was: Send pulsed high current through biomass across copper electrodes on a heat-retaining insulator At voltage/current/resistance conditions that just so happened to be physically perfect

And with that, I got consistent signs of Flash Joule Heating:

Instant sparks Localized carbon vaporization Conductive residue And most importantly: layered graphene on copper foil

Idk if I'm gonna live to see tomorrow after making this post, but the contraption I made is:

Reproducible Confirmed single-layer graphene (visually, structurally) Able to store and dump charge • I’ve already made a basic energy carrier from it • I can replicate it Voltage/current monitoring was pointless since the PSU ran at default settings anyway.

Later I'm probably gonna replace the banana peels with other biomass, build graphene energy carriers with layered copper foils, keep optimizing for power output, etc, etc.

Not gonna leak the full build (yet). I’m keeping this until I perfect it.

I’ll maybe release this in 3-4 years, but not now. I'd die if corporations see how little it takes to make supercapacitor-grade graphene.

TL;DR

I accidentally built a Flash Joule Heating machine with: A PSU I hacked the safeties off, copper scraps, pencil lead, styrofoam (later changed for safety reasons, don't wanna inhale toxic smoke), and a smart plug playing back taps. And now I can create single-layer graphene!1!1!1!1

Let this be my first trace. If I go missing, you know why.
