We don’t want your brains to explode, so just trust us that this is a truly one sided circuit. Being a mobius strip means that this circuit has uber geek bragging rights. Beware, your friends who have never heard of a mobius strip will argue until they are blue in the face that there are two sides to it. The circuit they chose was fairly appropriate, an LED “chaser”.
that has two sides!@!

I got a belly ache from laughing at this. More please!

genius, i love it.

AWESOME! That is so cool!

So when do we get to see a klein bottle variant?

Genius

I’ve seen plenty of single-sided circuit boards.. I’ve never seen a single-edged one before now though!

WOW

It has two edges.
Maybe if the paper were infinitely thin it would be one edge but it isn’t.

that is so cool!

Way to collapse the universe in on it’s self.
No really good job though I don’t know what made you think to do that, but yeah.

@ClockSmith : look again, one side, one edge !
cool !

It’s a trap!
It’s all done with diodes and tape!
your brain isn’t prepared for mind bendingness of this magnitude!

It does have a single (topological) edge, but then again, so do most other circuit boards (unless you count drill holes). Topologically, a rectangle boundary is the same as a circle, is the same as any other closed curve. I guess a cylinder “board” would have two edges.
Still, neat project.

Cut it in half down the middle… trust me.
way to bet for free beer, obvious when you think about it but a little unexpected.
Oh and nice fun circuit!

Oh my sweet, holy, jammydodgers! That is the sweetest thing I’ve seen on Hackaday for ages.
Just about to start my own with an SMT 40106 and 4017.

Where do I get that sweet conductive ink? It looks awesome!

my brain hurts now.

so a donut board would have 0 edges?

Awesome,
Also, google has no relevant results for “spherical circuit” **rummages around for a sphere to electroplate**

Great hack! Simple, creative and unique.
An appropriate application of ingenuity indeed =)

@wolf:
Why not use something like a racquetball with your electronics stabbed into it (or glued on), and conductive ink to connect them together? It probably wouldn’t be all that durable, but it would be a spherical circuit, wouldn’t it?

Similar conductive paint is used to repair rear-window defrosters.

yeah, you can make through hole connections from one side of the board to __the same side__ of the board. i have to think about circuit for such a routing …
