Larson scanner

[SecretReeve]

Okay, I know im new around here but I have a problem.

I'm really struggling to find a GOOD larson scanner schematic that is relatively easy to put together with readily available parts, runs on 12v and can be small enough in size to go inside a cylon centurion model.

I dont suppose anyone around here can help out with this?

Primarily it needs to operate 6 SMD leds at 12v.

I dont mind so much if its a digital chip like the ATtiny2313 but basically just need the schematic and if its on a chip, the code to operate it and possibly some instructions on how to go about it.

thank you in advance.
