Huge Smoke Ring Generator

I could see myself building one of these smoke ring generators. Too bad they need calm air to operate, I could imagine building some automated ones that would be great for ballparks, fairs, birthday parties… But it looks like if there was anything other than absolutely still air they would not operate as expected… Videos and more pictures after the jump. “Made from a discarded compost tumbler measuring 80 cm

Cooler Master’s GeminII

How much cooling do we need? This looks more automotive than a computer part… “So you think that your computer may be “heating up” a bit too much? Doom 3 and Half Life 2 are renowned for intensely heating up your PC. Even if you don’t have those and you feel a bit too much heat roaming inside your box, you could get your worries deleted with this massive boy.

Multigate FET technology creates faster, more efficient ICs

Is there any limit to how small circuits can get. It seems that whenever there is an obstacle a solution is found. Source: Electronic Products “Addressing the challenges in ever-shrinking ICs of maintaining functionality while consuming less energy in a smaller space, researchers at semiconductor solutions provider Infineon (Munich, Germany) have developed what is presented as the first complex circuit fabricated using 65-nm multigate FET (MGFET) technology. With a footprint

Kuka Juke Bot, the Robotic DJ

Want to be a DJ? You can go hands on with a modified Wiimote called the WiiJ. But when you get serious the Kuka industrial robotic DJ is the only way to go! Videos and more pictures after the jump. “The Juke Bot is a pair of Kuka industrial robots; each is surrounded by a set of platters (you know, vinyl LPs). The two bots act independently, deftly grasping an

100psi Hand Held Self Contained Air Cannon

Part of this video that we featured a short time ago was this Hand Held Self Contained Air Cannon. Now we can see some close up pictures and a detailed description of how it was made. What will come out of the FastMHz crazy high voltage lab next? We will have to wait and see… “This is a relatively simple device bodged together from junk I had around. Take some

Scanner Lamp

Transform your old scanner that is just collecting dust in the closet into a cool tech lamp. “This instructable shows you how to make a desk lamp out of scrounged scanner parts and a few extras from Home Depot. I have set up a small solar array, controller and a storage battery. I wanted to make some low power lighting that I can use in my office that would not

How is the fake candle power trick done?

Ok, I am not going to insult anyones intelligence here and claim that this video could be true. I am curious how it is done though. My theory is that during one of the early cut scenes the nails that are inserted into the candles are connected to power from under the table. Or longer nails are inserted and there are hooked up to power from the back of the
