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.

What with all of those parties and all of the rich food and drink over the festive period you may be feeling a little groggy or slightly under the weather to say the least.

Forget all of the traditional remedies for hangovers etc, for you may need a touch of brain floss to clear out all of the aches and pains, or maybe not! Depends on your point of view.

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

Wow check out this “dice” video…amazing…Up until today I had no idea Dice Stacking was even a hobby let alone a sport to some people. Well after watching this video I was pretty impressed and astonished

Wow, check out this Jacobs Ladder too!

This is how I used a neon sign transformer to create my own classic sci-fi prop the Jacobs Ladder. A Jacobs Ladder is nothing more than two vertical wires attached to a very high voltage. The wires which form the ladder are close together at the base but diverge as they go up. When switched on an electric arc forms at the base of the wires. The arc heats the air above it and in doing so forms an easier path for the electricity to take. The arc moves upwards continually heating the air above itself and rising to take the easier path until eventually the arc reaches the end of the wires and leaps into the air. Once free of the wires it dies but a new arc starts again at the bottom of the ladder. The arc itself moves with a very distinctive buzzing noise. These devices are most usually seen in old sci-fi and horror films and the houses of strange people.

Here’s a cool DIY on making your very own Jacobs Ladder. I always goto Fry’s with my friend Eric and find that they have this giant Jacobs Ladder that’d go off as soon as you were about to touch motherboards and whatnot. But this is great that now I know how it’s made.

The basic construction and principle of a Jacobs ladder is that a metal vee is formed from two bits of wire and a high voltage is applied across them. The electricity arcs across at the bottom of the vee where the electrodes are closest together. The air that the spark is passing through is ionised making it a preffered route for the arc, so when it heats up and begins to rise it drags the arc up the metal vee pulling it wider as it goes. In a correctly set up ladder the arc will travel all the way to the top where the wires have a sharp outward bend in them to pull the arc apart to the point that it extinguishes and the whole process starts again at the bottom of the vee. Here’s a picture of the base of my own Jacobs ladder showing the mounting of the wires.

Yey, I finally got a magic trick down pat. I am starting to gain some 6th sense with cards…maybe I will goto Vegas soon.

Okay, this is totally unrelated with golf, you’d think… But it is totally related!

A good golfer must learn his trick shots just like in card tricks…

I need one of these touch Tetris where you can actually move your whole arm to guide your boxes. (If I can only do this in the warehouse where everything fits, we’d save a lot of space…) (thinking of our warehouse pictures, i forgot to updated with ALL our Mattress-in-a-box(es)…visit our mattress store within 26 hours and you can save 20% OFF our retail prices…) (By the way, the only tightest and best stuff get marked as “Magic” under our category section…)

SparkFun just moved into some bigger and better offices; they are still in Boulder and cranking out orders for various kits, components, and more. We dropped by the new space last week to check it out and congratulate them on their expansion - [Flickr Photoset]

Wow, this is somethin’ I’ve always wanted to make with the free laser Dragonlasers sent me a long time ago…

But here it is! Looks like he’s from the UK.

P.S. Remember we ARE giving out a FREE Dragon Laser to the top commentator this month.  So make sure to participate.  Looks like Brian is going to get it at this rate.

Basically this little device produces HHO and feeds it into your fuel line in your car. The HHO is produced by distilled water and baking soda. The only drawback is that you much keep adding the distilled water and baking soda once a week.

This is a very good idea. I’ve heard of water injection systems but this one actually injects HHO.

Looks pretty cool to me, has anyone tried it yet?

I met this guy at the Maker Faire show along with Phillip Torrone. This would be great for my SUV… :p

Check out the Water4Gas website if you wanna order one and save some gas and earth too.

Congratulations! You have just found a way to own a water-to-energy converter for your car. Water4Gas is one of the most PRACTICAL free-energy devices, marked by extraordinary simplicity and effectiveness. You cannot get anything, anywhere near this good, for even four to six times the price.

We offer devices that use a little electricity out of your car’s battery, to separate water into a gas called HHO (2 Hydrogen + 1 Oxygen). HHO, also called Brown’s Gas or Hydroxy, burns beautifully and provides TONS of energy.
