Happy Valentines Day!

A few years ago I created a little valentines day project, shown in the video at the end of this post.  It’s basically just a multi-vibrator circuit with two groups of LEDs, arranged as an inner and outer heart:

The full schematic is shown here, click on it for a full enlarged display:

Finally, if you want to download all the project information, you can get it here.  This project is considered to be in the public domain.

I’ve thought about doing a new version actually, with a MCU for the LEDs to control brightness fade in/out etc.

Maybe next year!
