We're making our own Wireless LEDs! Once again thanks to PCBWay.com/?from=atomic for sponsoring the channel.

We had a look at these cool wireless LEDs in this video: youtu.be/xJc-Dkvh4Q8

And I said - "It would be really easy to make your own"...

So here you go - a complete working set of DIY LEDs with the driver circuit knocked up on some Breadboard.

I am cheating slightly and using one of my ESP32 as the oscillator, but I'm sure you've got a supply of these ready to hand if you watch the channel regularly.

The ones I got from Aliexpress are available here (affiliate link): https://s.click.aliexpress.com/e/_A4gUEH

To make your own, you'll need some 2.2mH inductors, 220pF capacitors and some LEDs.

I'm sure you've probably got these already - but just in case (and for the affiliate clicks!)

Capacitors: amzn.to/3oAgn7R
Inductors: amzn.to/3kBw6SH
LEDs: amzn.to/3cdh3KH

And if you are in need of an ESP32 board - the TinyPico is a great option: amzn.to/3nglR8k

The code that generates the signal from ESP32 is here: github.com/cgreening/wireless-led-driver
