Laser Etching an iPhone 5

Laser Etched iPhone 5

CrashBangLabs in Regina recently got their hands on a laser cutter. The Full Spectrum cutter was donated by a local company, who were upgrading to a larger machine.

With no laser cutting experience, [Brett] decided that his first project would be laser engraving his iPhone 5. This is a bit of an ambitious first project, since the power and speed would have to be set correctly to get a good contrast level, and you only have one try to get it right. Also, using too much power might have turn the phone into a laser etched brick.

[Brett] used an older aluminium iPod for testing. Once the laser speed and power was dialed in, he loaded up the artwork for the real thing. The cutter did a pretty good job at etching the art, but as the etching started it became clear that an alignment error had occurred. Fortunately [Brett] decided to not interrupt the cutter, and ended up with a good looking phone, with a slight alignment issue.

After the break, check out a time lapse of the laser cutter doing its thing.

Laser etched PCB production

Like most of us, [reonarudo] isn’t satisfied with the current methods of homebrew PCBs, so he put a laser on a reprap and started burning some boards.

The basic procedure is to cover a copper clad board with matte black spray paint. A laser was installed on the X carriage of the reprap. [reonarudo] used cad.py to convert the board files into g-code and fired up his laser. The quality of the boards is highly dependent on the accuracy of the laser so after working through some mechanical problems [reonarudo] managed to make some passable boards.

We’ve seen just about every manufacturing method imaginable applied to PCB production. Etch resist and toner transfer do the job and a reprap milling machine is pretty neat, but lasers are so much cooler. While it may not be perfect (yet), printing PCBs with a laser shows a lot of potential. Check out a video of [reonarudo]‘s bot burning some copper after the break.

DIY DS Lite RumblePak


This one’s been making the blog rounds, but it really fits us. Nintendo makes one, but this instructables tells you how to make your own for a DS lite. It uses a PIC 12F675 to read the input line and activate a vibration motor from an old nokia cell phone.

Oh, speaking of instructables, I forgot to mention that they finally picked a winner for their laser etching machine. Of course, if you lack the budget, you can make your own for $60.
