Here’s a really cool laser matrix projector project that can be controlled via an iPhone!

The idea is to add some kind of projector capability to mobile phone (e.g. iPhone) that isn’t too complex or expensive.  Instead of using an expensive mini projector, I decided to use lasers instead to any bitmap font using a matrix of laser points, which is controlled by iPhone.

UV DIY – How to Make a UV LED Exposure Box!

I thought I’d post this cool UV LED exposure box since it “looked” super cool and there’s plenty uses for this hacked gadget.

The author of the DIY UV LED box made it orginally for PCB work and whatnot but you can also use it to “disinfect” your silverware and anything that need UV-disinfecting.

A UV exposure box is an extremely useful piece of kit. It can be used to make proper PCB’s. It can also be used to make other things such as intricate photo etched par

The Pharox LED Bulbs!

Yey, we finally have LED bulbs from Pharox that greatly increases the efficiency of light bulbs while lasting 50 times longer.  I have to say these LEDs are very handy for projects too while they don’t really product enough heat to hurt you even when you touch them.  Cool stuff.

The Pharox LED bulb produces a warm glow equivalent to that of a 40Watt incandescent bulb, but uses only 5Watts of energy. The Pharox bulb is compatible with standard fittings and has a stylish design that looks more like a traditional incandescent bulb, yet is 90 p
