Very nice! I would like to build similar blinkenlights as SMD version (etch some nice round PCB with coin cell in the middle), but still haven't had enough time to study how this works.
@k0rmus I started designing exactly that but ran in to trouble when my ED package can't put devices at angles. Also being an odd number of cells makes it hard to divide the circle up into even sections when you are working with a grid. Once I discovered I couldn't use components on any angle I didn't continue working out the positioning. The other issue is the caps need to be pretty big values (so like 7313 sized) which makes the board by fairly large for anything bigger than three cells.
@k0rmus@randomgarfield sucks the software won't let you do it easily, was thinking of writing some postscript by hand to do a layout myself, easy enough to rotate and restroke N-times in PS. The circuit shown uses 10 uF caps, and in operation the base-emitter+LED drop clamps their max voltage rating to < 4 volts. Small tantalum caps with 6v3 ratings should be available pretty small?
No. Say "Math." Not "Maths". It's not a countable or pluralizable.

Looks like the nokia game "snake" in leds..;)

Great project vk2, thanks for showing us. I may just go ahead and try this one.

Might be some fun to be had with RGB LEDs :o)

@randomgarfield Thanks for your remark. Because of big caps, it will lose all of the elegance.
