Getting Started
Alright, so I wanted to get some lights blinking in a specific way, like those flashes you see sometimes. Not just a simple on-off, but something with a bit more punch, like a fighter jet’s warning lights or something. Just a small project I decided to tackle.

First thing I did was dig through my box of bits. Found some small LEDs, bright white ones seemed right for this. Needed some thin wire, a small battery holder, and a switch. Kept it simple, no fancy controllers this time, just straight power.
Putting it Together
Okay, the plan was to get a quick double flash, then a pause. Like blink-blink… pause… blink-blink… pause. Seemed easy enough.
I started by figuring out the circuit. Simple stuff really:
- Battery pack positive to the switch.
- Switch output to the LEDs.
- LEDs back to the battery pack negative.
Now, getting that double flash without a chip was the tricky part. I decided to try a more manual approach first, just to see how it looked. I wired up two LEDs in parallel. The idea was just to flick the switch on and off real quick, twice, then wait.
So, I hooked everything up. Wires twisted together for a test, nothing permanent yet. Put the batteries in. Flicked the switch on-off quickly, then again. Yeah, okay, it kinda worked, but doing it manually was clumsy and not consistent. Not really the “fighter flash” I had in mind.

Thought about it a bit more. Maybe a simple flasher relay? Nah, wanted something more basic if possible. I remembered messing with basic timer circuits ages ago, but decided against the complexity for this quick build. Decided the manual “effect” wasn’t quite cutting it.
The Realization and Final Touch
Then it hit me. For this specific project, the “fighter flashes” weren’t about an automatic circuit, but about the visual effect I could achieve when I controlled it. The goal wasn’t full automation, but getting that specific look when needed.
So, I went back to the simple switch setup. This time, I soldered everything properly. Made sure the connections were solid. Used heat shrink tubing to keep it clean and prevent shorts. Mounted the tiny LEDs where I wanted them on my little model.
Tested it again. This time, focusing on practicing the manual switch action: quick flick on-off, quick flick on-off again, then hold off for a second or two. With a bit of practice, I could get that sharp, double-flash effect consistently.
It looked great! Exactly the kind of punchy visual I was after. Sometimes the simplest way is the best way, you know? It wasn’t about complex electronics, just about getting that specific visual cue right. Took a bit of messing around, but got there in the end. Just needed to rethink what “making it flash” actually meant for this build.
