paper

Okay, not really lasers… just LEDs in straws that look like lasers. I’ve been working on some paper circuit projects for Brown Dog Gadgets and after we talked about the Darth Vader card and other “laser” cards I mentioned Shark with Lasers and Laser Cats… so we had to make them. (Find these and more in the Paper Circuits section of the BDG site.)

These cards use drinking straws with LEDs and a bit of hot glue to give the laser effect. Check out this Shark with a Frickin’ Laser Beam…

Maybe you prefer cats to sharks? We’ve got that covered… Here’s a Laser Cat! (Not to be confused with Laser Cats, the short film.)

The diagram on each card shows the circuit, which is activated by a switch mechanism on the other side of the card (not shown.) More downloadable paper craft circuit projects can be found on the BDG Dozuki site. I’ll highlight some of the fun work we do every now and then.

It happened innocently enough. I had some index cards, and I started writing things on them. They were better than scraps of paper because they were more sturdy, and when I tossed them in my backpack, they didn’t get all crumpled up.

I kept putting these loose index cards into the front pocket of my backpack, and every now and then I’d take them out, look through them, rearrange them, and put them back. No problem.

Then I thought, maybe if I put a binder clip on them, they’d all stay together, and I could even put them in order. Wham! That was it. Before I even knew it, I was a Hipster Doofus with an index card/binder clip PDA…

Of course mine does have 1GB of flash memory, which I find quite handy…
