Kinect, Mouse, And Nerf Gun Combine For House Of The Dead

March 21, 2011 by Mike Szczys 5 Comments

[Tony Blanch] built his own motion controller for playing House of the Dead. It should work with any shooter that follows the ‘rail’ type of game play (your character is not free walking, but moves along a set path beyond your control).

Two parts come together to make this happen. The first is the Nerf dart gun that you see above. The circuit board fitted into the top portion of the plastic housing is from a five-button wireless mouse. The buttons are used to sense trigger pulls from the player. The second portion of the controller is a Kinect. It has been set up to work with a Windows 7 machine. [Tony] used the Flexible Action and Articulated Skeleton Toolkit (FAAST) to bind and track the gun controller, moving the mouse cursor on the screen to match the movements of the weapon. Check out the video after the break to see how responsive this system is.

This is a very interesting departure from the gun controllers we’ve seen before.

Digital Measuring Tape

February 2, 2011 by Mike Szczys 17 Comments

You’ll never come up short with this measuring tape. That’s because there isn’t actually any tape in the device; it measures distance based on the rotation of a wheel. Roll it across the room and you’ll get an accurate measurement of the distance the little bugger traveled. Like the Etch-a-Sketch from Monday this uses the encoder wheel from a mouse as the input. The IR emitter and sensor from the ubiquitous peripheral find a new home on the PCB that hosts the PIC 16F819. It monitors the rotation, turns it into inches, then spits that number out on a 7 segment display. Handy, and cheap!

555s For Your Mouse And R/C Airplane

February 1, 2011 by Noah Dunker 18 Comments

[lenny] decided to build a 555-based auto-firing mouse based on a 555 after seeing a similar PIC-based project we posted earlier. Lenny’s version is self-contained in one mouse without requiring a second mouse to act as the rapid-fire button. It uses only a handful of components, costs less than $5 to build, and doesn’t require any programming.

But then, [wfdudley] shakes things up a bit. He added a 4022 counter IC and some diodes to act as logical “OR” gates in order to create a unique blinking pattern (short-short-long) for the lights on a friend’s RC airplane. While this project involves more components, it’s definitely a trickier problem to solve with a 555 timer IC. We love seeing people choosing simplicity in design over popular off-the-shelf microcontroller frameworks as these two have done.

Don’t forget, the 555 Design Contest is still going strong, and you’ve got the entire month of February to submit your awesome designs. We wanted to highlight two of the more clever 555-based hacks that we’ve had in our backlog for a while, though.

Etch-a-Sketch Computer Is A Surprisingly Simple Hack

January 31, 2011 by Mike Szczys 12 Comments

We’re not sure whether to call this an Etch-a-Sketch upgrade or a computer interface downgrade but either way it’s unique. [Martin Raynsford] added a familiar red frame to his computer monitor with classic white knobs that control horizontal and vertical cursor movement. There’s even the click option by pressing the buttons in and, as you can see after the break, the modifications result in a perfectly usable digital Etch-a-Sketch. We’ve seen a lot of computer controlled versions of the toy which use fancy parts and take quite a bit of skill to build. This mimicry of the functionality is easy to build and the idea is genius in its simplicity. [Martin] separated the encoder wheels from a mouse. He placed each on one of the knobs and ran wires for sensors and micro-switches back to the original PCB which is stuck to the back of the monitor. From the computer’s point of view it looks and acts like a normal mouse but this is so much more fun (and less productive). Continue reading “Etch-a-Sketch Computer Is A Surprisingly Simple Hack” →

Security Audit Kit In A Mouse

January 29, 2011 by James Munns 23 Comments

Sometimes it helps to have an entire set of tools with you to tackle a problem, and sometimes it helps to take the discreet route. [StenoPlasma] took the latter of these approaches, and stuffed a USB hub, a 16 GB flash drive, and an Atheros based USB wireless adapter into a regular looking USB mouse to make a Linux bootable system in a mouse. Because he chose the Atheros adapter, he is also capable of doing packet injection with tools like Aircrack-ng, which can invaluable in a security audit or (white hat) hacking situation.

This is the only photo we have, so it could be possible that the mouse is no more than a mouse, however we know all of what [StenoPlasma] claims is 100% possible, so we’ll give him the benefit of the doubt, and hope this inspires others to hack up your own mouse kits. Be sure to check out the full parts list after the break.

Adding Auto-fire To A Computer Mouse

December 20, 2010 by Mike Szczys 49 Comments

[Peter Skaarup’s] been re-living the past by playing old-school games in DOSBox. He’s using a mouse as the controller but longed for the auto-fire button that many joysticks used to have. Instead of looking around for a gamepad with this feature he decided to add an auto-fire button to the mouse. He incorporated a PIC 10F200, along with a momentary push switch and a transistor. The push switch enables the autofire feature, causing the transistor to short the left mouse button about seventeen times a second. Problem solved, and with a couple of other pins on the microcontroller there’s room for this project to grow.

Interested in an auto-fire feature for your gaming console? Perhaps this Xbox 360 rapid fire mod will give you some inspiration.

Sluggy Wind Speed Sensor

December 4, 2010 by James Munns 7 Comments

Sometimes when we look at a hack, its to see how someone chose those parts for the project. In this case, it would have been hard to see it coming. [Janne Jansson] decided to combine a set of measuring cups, a hacked Linksys NSLU2 NAS, and a PS/2 Mouse together to make a self-contained Wind Speed Sensor for his roof. The measuring cups act as wind catchers, which in turns drives the rotation of one of the mouse ball sensors. This data is then logged and transmitted by the NSLU2. The NSLU2 is running a custom Linux based firmware, similar to how OpenWRT works for wireless routers.

To calibrate the device, he also made the best logical choice: to duct tape it to the hood of his car along with a much more expensive wind sensor and use that data to make his own device as accurate as possible. When placed atop his house with a 1500VA 220V UPS, the device managed 250 days of uptime before meeting its demise. Those 250 days also included 5 days of being frozen solid, yet still transmitting (somewhat meaningless) data. All of the relevant code and build instructions are available, for those of you with similar parts to spare.
