Fashion police

Apparently co-ordinating accessories is a minefield. There is a thin line between a hot new trend and a fashion faux pas. Bags, shoes and belts have been discussed excessively.
But should your hat match your walking stick?

argh now I have to get back to that project. Let me think about it some more.

(Weird and seldom-discussed characteristic of LED's: they work in both directions. If you put power on them they shine light, but if you shine bright light on them they put out a bit of electricity. So, you can use them for bidirectional communications, and if you're flashing them fast enough nobody can tell visually that they're sending signals and others are, in their off time receiving those signals.

Unfortunately it gets very complicated very quickly when you have a dozen of them all trying to talk at the same time, when some can't see the others.

Wow, I had now idea. It is amazing.
OK. I now need to buy me some LED's. A lot of them actually.

If you can buy in bulk from china you get way better prices. I had a friend who made a bodysuit covered in ultraviolet LED's once upon a time, 18 years ago when they were scarce as hens' teeth, so he bought 1K of them for the price 20 would have cost in the US. Be prepared for 10% of them to not work.

Hm. Now I have to think about a good way to generate 12,000 pwm signals for that cube. I wonder how they did it.

I think I will order them from China indeed. And will add some more cool stuff to the shipment.

A friend of mine is bringing a couple of huge super strong magnets for me from somewhere soon. The kind that cannot be flown on airplanes and can fly to each other across the room and kill people I think. That will be fun.
I also need to get some gallium to play with. And now I have to add LED's to the list too.

I have some smallish supermagnets. Those things are kind of terrifying. I've read about the large ones. YIKES.
There are some alloys like wood's metal that have gallium-like characteristics, as well, that may be cheaper.

Oh wrong thread. If you're not trying to build the cube:

would be a pretty good starting point for jewelry. Those things are like 1.5mm by 1mm each, so you can get several in a very tiny space.
