Remember my Green Laser Projectr DIY?  Well, here’s a similar DIY project except it uses a speaker to send vibrating pulses to the end-results beams instead of a motor.

So how does one go about making one of these things? Well, I made every effort to make construction as simple as possible for two reasons. One, electrical engineering is far from my speciality and I didn’t want to kill myself/ruin a laser I could only afford one of. Two, I always hated seeing incredibly awesome projects on the internet that I never had any hope of building due to funds and bizarre parts. That’s not to say you don’t need some basic soldering and construction skills, as well as a healthy respect for the power of laser light, but it’s definitely doable if you put your mind to it.

Thinking of making your own box kite?  Here’s a cool set of photos you can refer to making your own box kites!

I’ve been making these [box kites] for few years, and tomorrow I’m getting a bunch of people to make them at gas works park in Seattle. So I figured I would spice up my usual instruction set and put it on flickr.

Here’s a really cool NES Hack that shows you how to build an NES USB Controller that can be plugged into your computer via USB to play the games and load NES games/emulator from the controller itself!

Ok guys, ive gotten waaaaaaaaay too many requests to make a tutorial on this to ignore. Sorry it took so long. I recently made 3 more controller, each a little different from the other. I may make tutorials on those later. Next NES controller I make will need to be wireless, if someone does this before I do please email me at jaykaye2k9 (at] gmail [dot) com

Here’s a really cool DIY on how to build an automatic fish feeder.  This would be great to have around if you happen to be gone for a few weeks without having to worry about feeding your fish.

This is the fastest and cheapest way to build an Automatic Fish Feeder.

It automatically turns the light on, feeds your fish and turns the light off.

It can run for months by itself.

Here’s a really cool underwater ROV project that has detailed documentation on how to build one yourself.

The ROV submerging technique was originally using part of a bicycle inner tube and a car windscreen washer pump. However this method was very slow to respond and difficult to control and ended up either dropping the ROV like a stone to the bottom or rising to the top. Probably a little worrying having water pumped into the same chamber as the electronics but I tried to make it as reliable as possible and with this in mind I  incorporated a leak detection unit which alarms on the GUI and automatically surfaces the ROV. I gave up on this submerging method when  pumping water inside caused excessive internal pressure and blew off the end cap on the ROV despite being held in place with two clamps.

Check out this cool DIY on how to build your own 3D motion sensing controller.

Make a 3D interface using an six resistors, aluminum foil, and an Arduino. Take that, Wii.

The basic goal here was to make a 3D position sensing system that most people can build, while still preserving some semblance of functionality. To get an idea of possible applications, check out the demo video. If you think you can build one that is simpler and equally accurate, or slightly more complex and more accurate, share in the comments!

Here’s a really cool Chumby hack that will allow you to use a bigger 640×480 pixel LCD on your favorite little gadget.

Chumby is different; it is open source, and designed to be hacked. For example, the serial port is spelled out on the silkscreen for you and there’s a backdoor to enable sshd, so it’s not big deal to bring up the console. Because of its hackability, you are enabled to do significant modifications due to the availability of all levels of design documentation—hardware, drivers, and application software. While it would be an enormous task to, for example, open up a Zune and put a larger screen on it, here, in this post, I will show you how to hack a chumby to have a larger, higher-resolution screen without too much effort. The native chumby screen is a 3.5” QVGA (320×240) display, but after you complete this hack, you will be treated to a 5.7” VGA (640×480) display.

Remember they Chinese guy who made the helicopter? Well, here’s another Chinese guy who made a freakin’ submarine out of old metal barrels.

Talk about eco-friendly, this submarine probably is the most green submarine ever made.

Way cool huh?

I am gonna go make mine too now and start a new business.

Tao Xiangli made the 1.6 tonnes submarine mostly from metal barrels and improvised parts by hand, reports Zhong’an Online.

“Metal barrels are possibly the best material for me because of their low cost,” said Tao, a migrant worker in Beijing.

The 20ft submarine is cramped inside with room for only one person but it features pressure metres, monitoring cameras, a TV set, oxygen supply and headlights.

Do you think you will be directing any home-brewed movies anytime soon?  Well, if you are, here’s how to make a mobile tripod for those action shots.

Here’s a really cool USB Data Gloves.  I am not sure what you can use it for, but here’s the link to instructions on how to make one.

This is the reconstruction of a “Fakespace GL-8001” device with fully compatible serial interface via USB. This device fits into a very small SubD adapter housing, consumes low power (max. 20 mA), supports USB standby, may support a USB remote wakeup feature later, is much faster in responsiveness than the GL-8001, and the electronic components are fairly cheap, lower than 5 €.
