Texas Instruments Watch Claims It’s A Computer Mouse

[Jack Toole] and his team [Aaron King] and [Libo He] sent in their computer interface dubbed the Chronos Flying Mouse. The video above explains the concept very thoroughly, but we’ll reiterate some of the highlights here. The project uses a Chronos EZ430 with its accelerometers to wirelessly transmit delta positions of the user’s wrist. Add a little open source software and you have a regular PC mouse, a video game joystick, a game wheel, and a few other different devices in one. We just love the suave feeling of snapping to click.

Mouse Controlled Manipulator Arm

[Oleg] worked out a way to use his USB mouse to control this manipulator arm. Using a Lynxmotion AL5D (we’ve seen the AL5A previously) he drives the six servos with an Arduino servo shield. A USB host shield handles the HID end for connecting the mouse. The video after the break says it all, [Oleg] has no problem picking up that figurine quickly and accurately. Sliding the mouse controls horizontal movement in all directions. The scroll wheel moves the claw up and down. And holding the left or right buttons what using the control wheel closes or rotates the claw. All we can say is: Bigger, BIGGER!

Hands-free Input

This is a concept input device that [Tech B] built for disabled users. The device uses an accelerometer along with a piezo sensor (right click) and a push button (left click) to function as a mouse. The Arduino that resides in a breadboard on the side of the hat communicates with the computer over a serial connection, using PySerial to translate the microcontroller data into cursor commands with the power and ease of the Python programming language.

During development [Tech B] made a proof-of-concept video using a Basic Stamp which you can watch after the break. He found that this input device was less complicated, more accurate, and much less resource intensive than his webcam IR tracking system.

Super Quick And Cheap Trackball

[Elgatoandaluz] has posted this guide on how to tear apart a standard optical mouse and build a custom trackball. He’s using a ping pong ball , mounted above the laser as the trackball itself, which seems like it would be a little lite, but functional. The case is scrap cardboard. We really like that you could toss this together relatively quickly and have a custom layout. He recommends using Sakasa Mouse for inverting the axes and X-control for mapping the buttons(direct download).

Custom Controllers For PlayStation 3

[Matlo] worked out a way to use a PS/2 Keyboard and USB mouse with a PlayStation3. The hard work is handled by a Teensy board, which is becoming a popular choice with controller hacks. It interfaces with the keyboard and mouse, translates their input, and sends joystick button commands to the PS3. He is limited to mapping the inputs from a PS3 controller but that is still enough options to work beautifully with first person shooters, especially if you’re used to gaming on a PC instead of a console. If you want to give this one a try, head over to the google code page to download the source code.

DIY Scratch Controller

There’s something viscerally pleasing about simple solutions. [Kip] came up with one in the form of a scratch controller. The spindle from an optical drive is used to hold a CD in place, which acts as the LP for scratching. The sensor from an optical mouse is mounted upside down below the CD and detects the rotation of the disc. From there it’s just a matter of setting up your software to get the reading from that mouse. He’s had some trouble finding disc surfaces that the mouse sensor will read reliably.  We’d recommend trying some of those stick-on inkjet CD labels.

This is similar to a scratch controller we saw in 2008. That one was actually repurposing the IR encoding from inside of a mouse. We’re not sure which method would work better, but either controller will make a nice addition to a Flexi Knob setup.

Will This Mouse Get Me Kicked Out Of The Coffee Shop?

This [Dwight Shrute]-esque project will let you try out your taxidermy skills. Apparently you can acquire a ‘wetware’ mouse fresh or frozen from pet stores. We just need to wait until fall when our pantry is visited by the less-domesticated variety.

A travel-sized optical mouse acts as the replacement guts. Some creative dremeling brings the plastic housing down to a more acceptable shape. The furry bits need to be processed using the mouse taxidermy guide before they are fit over the electronics. What you end up with is a creepy peripheral that nobody wants to use.
