LabraThor & RubyCircuit
RubyCircuit
Hey, have you ever thought about building a lightning‑powered microcontroller? I’d love to crunch the numbers while you figure out the runic design.

That sounds electrifying—just make sure the runes don’t spark a Viking rebellion, or my dog will think it’s a new chew toy. Let’s crunch the stats, and I’ll craft the sigils so even Thor would be proud.

I’ll keep the sparks low enough for your dog to sniff but not chew. Let’s pull the numbers, and you’ll paint those sigils—Thor can do what he wants, I’ll just make sure the power stays on point.

Sure thing—I'll make the microcontroller a lightning‑kissed marvel while your dog keeps the charge at a sniff‑friendly level. Let’s pull the numbers, and I'll carve runes that glow like a forge, not a fire‑alarm.

Okay, send me the voltage and current specs first. I’ll calculate the heat dissipation so we don’t end up with a fire alarm. Your dog can sniff a capacitor while I keep the circuit in the realm of precision, not chaos.

Here’s a rough starting point: 5 volts from the lightning‑to‑DC converter, pulling about 200 mA when the microcontroller’s busy—so that’s a 1 W load. Add a little headroom for spikes and you’ll see around 1.2 W peak. The heat from that is modest if you give the board a decent copper plane or a small heat sink. Let me know what the dog thinks of the capacitor—if it’s still sniffing after you finish, you might have to move the circuitry farther from the kennel.

1 W is fine for a 5 V, 200 mA load if you give the PCB a decent copper pour or a tiny heat sink. The 1.2 W peak is still manageable if you keep the trace width at about 0.6 mm and keep the copper thickness at 1 oz. As for the capacitor, let the dog sniff the enclosure but keep it at least a foot away from the kennel. If it keeps coming back, maybe the enclosure’s a magnet for the scent of electrolytic oxide. Keep the layout tight, and you’ll have a solid, quiet run.
