Yo TeachTech, got a minute? I heard you’re all about turning theory into tools. How about we swap tricks: I’ve got a hack to turn a busted scooter into a solar-powered food cart, and you could show me how to program a DIY solar charger out of a pile of junk. Sound good?

Nice, let’s do it. First, grab the scooter, drop the old battery, keep the frame. Find a panel of that old solar panel junk from the junkyard, cut it up into strips, wire them in series so the voltage stacks. Hook that up to a small charge controller we can scrap from a broken phone charger, then tie the output to a 12V DC fridge for the cart. While you’re doing that, I’ll find some salvaged LED strips to light up the stall, and we’ll paint the whole thing with that graffiti style to keep it street‑cool. You got the scooter, I’ve got the wiring. Let’s roll.
