With technology rapidly evolving, light emitting diodes are in virtually every single electronic device on the market. They don’t produce any heat, consume less power, and emit brighter light than conventional bulbs. Furthermore, they are incredibly inexpensive and are easy to solder, allowing any inventor to utilize them with ease.

1. New to LEDs? Not a problem, everyone has to start somewhere. Learn how to solder them, then build a few beginner projects. These three projects are great for anyone just getting into electronics and wiring.

2. Using a standard digital camera and a few infrared leds,you can make your own, high quality Night Vision Security camera for about $5.

Cool stuff here.

Have a look at this cool Nightclub LED Lighting System. If I owned a nightclub this system would be one of the first enhancements that would be added. The company has done quite a few 3D models of their designs which provide a great idea of what the end result will look like. I would be interested in knowing what type of RGB LED element they use and how they get the color to fill the globe as evenly as they do.

Check out the Atmel AVR temperature controller hack, although I made a better one last year that can be controlled via ethernet, the case looks awesome!

Wine doesn’t like subzero temperatures, and during wintertime, my “winecellar” got pretty cold.
There was an electric heating element, but the thermostat was broken, so it was either full burn or nothing.

That’s how the temperature monitor/controller came to be.
It was an obvious task for a small processor and I’ve always wanted to test the Dallas temperature sensors.

So, I designed this little device which could monitor the temperature and control the heater.

Now this is my sort of coat! It’s made from fake fur, so there will be no problems with the angry green chasing you down the street, after all you would be able to get away in a coat that can be seen from the space station!

It has a polka dot design and is completed with over four hundred coloured LED’s which you are able to select and change the colours as your mood fits. But if that is just not satisfying enough then you will just have to go for the matching hat and scarf.

Unfortunately there are no prices yet, so I’ll have to wait!

Cool lookin’ Interactive LED table!

I purchased one of the Interactive LED Table kits from Evil Mad Scientist and built a table, it took a week to assemble, and almost two months to make the table part, but it’s pretty awesome. Tons of photos, and a few videos of the building process, and final table on the link above

This is kinda cool way to control an LCD hooked up to Ardunino with browsers including your mobile phone.

In conclusion, this code may be pretty ragged, but the concept is what is important and it should be enough to get you started. You obviously can’t do anything too intense with this. It could be used to do some simple but cool things though such as controlling your house from your cell phone, or feeding your dog or cat over the internet, etc. Once again, please e-mail me if you need help getting it working for your project.

It’s that time of year when all of those funny Christmas ideas come out, some of which will see a whole host of gadgets that do all sorts of things, but very rarely do anything useful.

The Think Geek Snowbot Features:
USB Powered (for great justice!)
Scanning LED Robotic Eye
Rate of sweeping is controllable via knob
Selectable LED Robotic Eye Colors (Blue or Red)
Authentic Snowbot Sound (on/off switch)
Rotating, articulating metal arms
Coiled (12″) USB cable extends to 30″

This is a nice but almost useless gadget which serves not purpose other than to have a good laugh while at your desk.

Priced at $9.99
