Control Freek has a new and unique tennis racquet that aims to prevent sweaty palms by including an air-conditioner in the handle. I suppose this is big news for the Tennis world because sweatty palms will lose you matches and hurt your grip.

No batteries required. It was specially designed to capture air in the handle every time you swing the racquet. That air comes out through the holes and onto your palm, hopefully improving your game. I’m not sure that this would work, but if you’re the sweattiest palmed Player on the court it will cost you $275 to cool off.

There may be a reason that older people who use canes don’t fish very often. Could be that it’s a pain in the ass to use both a walking stick and fishing pole at the same time.

Those with walking problems will be happy to now find both in one device. Though it might get them some strange looks when not fishing. It’s 35-inches tall, with a rubber foot and metal/plastic reel, and only $39.95. Obviously it could be more stylish.

Let’s say you’re riding your bike around town and suddenly you have the urge to launch tennis balls at something or someone. Thanks to this inventor, you can satisfy that urge and launch away. It’s completely eco-friendly too, built from two recycled bikes, scrap steel and wood, even a leaking water jug and a lacrosse stick.

Pretty simple but genius way to make a tennis ball launcher. As you pedal the bike, you power 2 other bike wheels that launch the balls. Perfect if you like to ride your bike to the Tennis court. Or just blast pedestrians and the like.

The dumbbell hasn’t had an upgrade in a long time, if ever. Well, now suddenly they are getting smarter. What if you could have an entire set of dumbbells in one compact design? That’s the idea behind this concept by Sang-Hoon Lee.

You can digitally adjust the weight of the dumbbell. There are tiny balls inside the dumbbell that spin. The faster the balls spin, the heavier they weigh, thereby beefing you up so you don’t look like a girly man. You can adjust the speed of the balls, which adjusts the weight, simply with a dial and pushing buttons. The set comes with a charger cradle..

The world of geek sports just got more competitive. Tetris and arm wrestling have collided and now has a name. Trestling. Not since peanut butter collided with chocolate to create the Reeses cup, has there been such excitement.

It’s got everything a geek could want. It’s competitive and violent, with two players smashing their arms against sensors that move their blocks left and right. All to the tune of “Eye Of The Tiger” of course. Buttons control the rotation of the pieces. Do you have what it taks to become top dork in the championship tournament? It actually looks pretty fun and challenging. Check out a video below of the game in action.

When you’re playing a game of catch, a radar gun isn’t exactly the most convenient way to measure a ball’s speed. The Glove Radar is an affordable way to measure how much heat your friend is throwing your way. It attaches to the back of your glove with a weather-resistant nylon cord. Sure, it looks dorky, but what are ya gonna do?

It uses microwave Doppler technology to measure the ball’s speed as it approaches. When the ball arrives you’ll see it’s speed indicated in mph on the LCD display. The Radar is powered by a single 3V lithium battery, which isn’t rechargeable, but it’s good for about 5,000 speed measurements. You’ll probably be bored with it long before then.

If I were a skater I would do all of my skating at night using the Photon Light Board. I would turn a 360 pivot into an ollie while people would swear up and down that they saw a bright neon UFO descend down that staircase.

With the Photon Light Board, I could do it too. Since all the boards have such highly customizable lighting patterns and many colors to choose from. It would be like doing tricks on a Lite-Brite. But I’d probably break my neck doing a rad stunt… So it’s probably best if I let that dream die. But you don’t have to. You can ring your board with LEDs, add drop lighting, or even skateboard headlights. Each Photon Light Board has about 30 lights.

Hardcore Baseball fans will love this device from Ambient. The Ambient Devices Baseball Scorecast. It will bring you live scores on your desk, without the need for a PC.
