I have a passion for tweaking things. Whether it be modding video game consoles, creating custom laser displays, or any creations with lights I love solving problems through unorthodox means. I like to go wherever life ends up, often on some unexpected adventure with new ideas and the willingness to have fun. Since things never go as planned in life, it helps to be adaptable.

    Four-Motor Laser Spirograph

    If you are going to use lasers in a public display, you should really find a specialist to correctly set everything up to not hurt people. To give you an idea of how it works, for public displays in the U.S., if the power is over 3.82mw (extremely weak) the laser projection can never go into the crowd itself. It can go *above* the audience's eye level (usually higher than 12 feet), but never into the crowd. The reality is a little more complicated. Tons of clubs violate these rules by shining laser projectors into he crowd, usually with beam-splitters included to cover more of the crowd. The legal limit is not the power (in mW) of the laser. It's the amount of light (power) at a certain point (someone's eyeball), received at a certain distance (how far the crowd is from the stage).

It's the amount of light (power) at a certain point (someone's eyeball), received at a certain distance (how far the crowd is from the stage). A professsional installer measures the power at different spots in the crowd. =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Personally... Get a fog machine to make the beams more visible, and buy or make beam expanders. They are also called: biconcave lens, double concave, or a diverging lens). It makes the laser beam WIDER!!!! Which makes it look MUUUUUUCH better than a very narrow/thin beam. =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Profesionally made beam expanders are expensive. Because most people purchasing laser lenses need extremely precise parts (think university experiments). For a common display, it really doesn't need to be accurate. Go buy a double concave lense, and place it in front of the projector and see how it turns out :-) Another option, is a diffraction grating, also called a laser matrix grating. It splits the power of one laser beam into 100-1000 beams, and they're pretty cheap (generally $10 + shipping). I hope that helps.

  • Xbox 360 Wireless Controller Ring of Light

    The flashing simply means searching for device.You are trying to use a 360 controller via a USB Micro adapter correct? 360 controllers use XInput, which is a custom interface system. You'll need to use another device, most commonly people use PS3 controllers because Bluetooth is a common standard.I doubt you'll be able to get the 360 controller working with Android. Even if you can plug it in. Good luck!
