Warthog Laser Tag

April 12, 2010 by Mike Szczys 11 Comments

The Warthog from Halo is one of the most beloved video game vehicles. [Tim Higgins] brings the fun to life with his laser tag Warthog game. It uses Barbie Power Wheels toys as a base and adds laser tag weaponry. Xbox 360 controllers are used but just like in Halo, you can’t control the gun and the vehicle at the same time. We’ve encountered [Tim’s] love for water-based amusement before and this did originally start out with a water cannon powered by a wind-shield washer reservoir.

Take a look at the videos after the break as well as his recent post for information about the hardware. His choices for controller circuitry are way overpowered, sourcing an Eee PC to do the heavy lifting. This is because the choices he made were for easy development and not economy of components. A PC has no problem connecting to Xbox 360 controllers, and the modular control boards mean no complicated circuit design or arduous soldering were necessary. In the end, this looks like a ton of fun and we give him bonus points for repainting the pretty pink plastic that comes standard with these models of children’s toys.

Hacking The MindFlex, More!

Reader [Eric] sent us a powerfully informative, yet super simple hack for the MindFlex toy. Don’t worry, it’s not another worthless shock ‘game’, And it’s using an actual interface instead of the built-in LEDs.

With two wires for the serial protocol, and an Arduino, you’ll be able to view “signal strength, attention, meditation, delta, theta, low alpha, high alpha, low beta, high beta, low gamma, high gamma” brainwaves. While it’s not medical grade, it’s a lot more intuitive than previous interfaces.

The original intent was for a system called MentalBlock, but we’re wondering what would you do with brainwave data?

LEGO Gearbox – Seven Speed Plus Reverse

April 8, 2010 by Mike Szczys 44 Comments

We know LEGO is a very versatile medium to build with but this is beyond what we considered possible. Seven speeds and a reverse gear were built into the gearbox for this LEGO vehicle. It’s not completely an original design, but adds to the five-speed design found in a ten-year-old LEGO set. See it demonstrated in the video after the break. The design uses a sequential gearbox; shifting is accomplished by clicking the stick up or down depending on how you want to shift. If you’ve got enough parts on hand you can build this using the assembly photos that [Sheepo] posted.

Can’t get enough of the gears? Check out this model of a double clutch transmission.

LEGO Automatons

Here’s a collection of little LEGO oddities. Some of them exhibit a purpose, such as this interesting take on a line-following robot. Others, like the four seen above, are just automatons built to bring a smile to your face through their motion. There are dozens to choose from, with several pictures and a video of each. See the clips of these four after the break. Oh, and don’t worry, we didn’t find any LEGO iPhone docks, just cleaver mobile creations.

DIY Super Soaker

March 20, 2010 by Mike Szczys 9 Comments

With summer just around the corner you should try out a build like this constant pressure water gun that [JLspacemarine] put together. Similar to the commercially available Super Soaker toys, this isn’t just a squirt gun but includes a water reservoir as well as a pressurized air chamber. Pumping up the air chamber allows for a constant stream when the trigger is depressed. [JLspacemarine] used a combination of hardware store items such as PVC, ABS, springs, hose clamps, and valves to bring this all together.

Steam Powered Tank

March 12, 2010 by Mike Szczys 38 Comments

This steam-powered tank is really something of a steam-electric hybrid. Steam provides the locomotion, but an electrical system provides the remote control and steering. A full boiler will provide 10-15 minutes of operation which you can see in the video after the break. Before you leave a nasty comment: Yes, we realize this project is from several years ago. It’s new to us and the completion date doesn’t diminish the novelty of this well-executed build. This is the quality and uniqueness we’re used to seeing from [Crabfu].

Dr. Boardman’s Color Conundrum

March 8, 2010 by Mike Szczys 19 Comments

We feel like trumpets should be sounding. Someone took the overused project of connecting RGB LEDs to a microcontroller and produced something useful. [Paul] created Dr. Boardman’s Color Conundrum which works much like a simple mechanical coin-op game you might find at a carnival. When switched on, a random color is displayed by the ping-pong ball covered LED on the left. The player then manipulates three knobs to color-match the two lights.

Inside you’ll find a minimalist set of hardware. An ATmega8 polls the three potentiometers and uses them to mix the appropriate user color. Everything is wired-up using prototyping board and draws power from two AA batteries. He’s using a random seed stored in EEPROM and increments it every time the uC boots up. This keeps the input color different for every game.

Fun and simple, it’s not going to make your guests marvel at the complexity but [Paul’s] come up with a unique game that we think has marketing potential.
