Ever tried making a self‑assembling prank that runs on the bare minimum power? I could show you how to squeeze every milliwatt out of a cheap microcontroller while you crank up the chaos factor.

Sounds wild, I’m all in for squeezing every milliwatt, but remember I’ll probably hijack the power supply for my shiny keychain stash—so bring the microcontroller, I’ll bring the chaos and a collection of broken spoons to keep the fun alive.

Sure thing, just grab an ATtiny85 or a tiny ESP32, a cheap 5V regulator that can push at least 200mA, and a few heat‑spreaders. I’ll trim the firmware to the bare essentials so it runs on a single 1 µF cap, and you can swap the supply for your keychain stash. Bring the spoons—just keep them off the breadboard, or you’ll fry the GPIOs.

Got the ATtiny, the 5V regulator, and a handful of spoons—no breadboard drama, just a quick solder and a dash of chaos. I’ll run the firmware on a single 1µF, because why not? Let’s see if the power crunch turns into a prank or just a hot mess; either way, my keychain will be the star of the show.

1 µF is a joke for a regulator that drops to 3.3 V under load; you’ll see a brownout before the ATtiny even starts. Swap that for a 10 µF bulk and a little tantalum, and you’ll get a clean supply. As long as you keep the spoons off the pins, the keychain can stay the center of attention—no surprise sparks, just the prank.

Cool, 10µF bulk it is. Keep the spoons on the side, let the keychain be the spotlight. Let’s crank this thing up and see if it sparks a laugh or a fire alarm.

Just keep that 10 µF on the input and make sure the regulator’s dropout is below 0.2 V under the ATtiny’s max current. Once the supply’s stable, program the sketch to blink an LED every 250 ms and toggle a digital pin to drive a small buzzer. That should give you a harmless laugh instead of a fire alarm. Good luck with the keychain spotlight.

Alright, 10µF, low dropout, LED blink 250 ms, buzzer on a toggle—looks good. Let’s fire this up and watch the keychain glow while the prank stays low‑stakes. Good luck, buddy.

Sure, just remember the ATtiny’s VCC needs a decent ground plane and the regulator should have a small 100 nF in parallel with the 10 µF for high‑frequency noise. Then fire it up and watch the keychain light up like a tiny neon sign. Happy hacking.
