lased, Networked USB Lamp

New Project: Lamps

Hooray, a new project!

At work it often gets very loud in my office, so everyone wears headphones. Unfortunately this makes it difficult to get someone’s attention, because they’re all rocking out to David Bowie or whatever. Also, it gets very dark in my office because we don’t have desk lamps.

The solution, clearly, is networked USB lamps that you can make blink if you want to get someone’s attention. Someone else suggested a cheaper solution would be Nerf balls to throw at each other, but that’s way less fun to build.

Lamp prototype

Here’s my prototype for part of the first lamp. I’m making 5 lamps total, and they’ll all be different. Each lamp will have white LEDs for general lighting, and then different colored LEDs for various alert functions. The first couple will probably just use normal, colored LEDs. I’ll try some RGB LEDs later, they’re just so stupidly expensive compared to normal LEDs.

I wrote a program in Processing to generate the parts, so I can easily make models of different sizes or with different thickness materials. I’ll post it in a bit when things are a little farther along.

I’m using an Arduino to prototype the electronics, but will probably switch to something cheaper like an ATTiny when I go to build the lamps.

Just because it’s handy, I’ve written the prototype drivers for the lamp in Processing, but that’s only because I already had it open. Eventually I’ll want something that can hang out in the systray / menu bar, and I don’t think Processing allows for that. Tho one advantage of Processing its an easy way to make executables for both Mac and Windows. Or it pretends to be, I’ve had inconsistent luck getting Processing applications to run on my windows machine. Thanks, Java!

Lasering Rocks

In case you were wondering “Can you laser etch rocks?”

Lasering Rocks

You totally can.
Robo-rock was etched in raster mode at 20% speed and 100% power on a 35 watt laser.
Unlike the last robo-pet I had (grass) this one should be substantially harder to kill.

Related ideas we’ve come up with include etching a bunch with electrical symbols and casting them like runes for circuits. Of course this led to a discussion on casting bones, and then etching them.

So. Much. Laser.

Today I made EVEN MORE STUFF on the laser cutter. AND, this time I actually listed something for sale on Etsy. This is the first time in many, many months I have actually listed things for sale (excluding mindlessly hitting renew when things expire). It’s awesome to actually make things I like again.

I made the city ring in blue acrylic:

I also made it in white acrylic but there was a small problem. The white was slightly warped. This caused the laser to be out of focus when it hit it, making things generally melty.

Tri-city area

Within an hour of listing the blue ring on Etsy, I’d sold 2. So I guess they’re a hit? I also made one out of day-glo pink plastic. It’s a little blinding.

Laser Rings

Ringtown

I tried to make a tiny city on a ring. It came out OK but I’m still figuring out what scale works with what materials. Also, balsa is useless; never use it for anything.

I have been using a program called QCAD to draw out the designs, and its been kinda frustrating. The documentation for it is terrible. Bre found a guy who does tutorials which has helped a little, but its overall a slow process. In some ways its similar to Rhino, which I learned in college, but the UI is totally different and its annoying. I’m debating whether to reinstall XP on my laptop (it has Ubuntu right now) just so I can use Illustrator instead. Because apparently I have forgotten how much I hate Illustrator.

I also made another ring, but the basswood was too weak for the design, and the notches were a tiny bit too small.

Tinysaur is Tiny

First and foremost, the laser is now up and running at the hackerspace. One of Bre’s friends sent him a dinosaur pattern, and I decided that said dinosaur pattern would be more fun if it was ridiculously small.

Three tries (took a while to get the scale right) and some tweezers later… TINYSAUR

Tinysaur

Here’s tinysaur next to Bre’s dinosaur:
Tinysaur workshop

If you’d like to make your own Tinysaur but lack a 35 watt CO2 laser, you can get the pre-lased kit on Etsy or if you’d rather skip the tedium and just have a tiny T-Rex, you can get a completed Tinysaur as well.
