Wireless optical mouse hack

I fired up the soldering iron, removed the microcontroller chip, and soldered links in to the PCB at the locations marked in red above. After doing this, the top view of the hacked mouse now looks like this Top view after hacking Now just screw the cover back on the mouse and, to all intents and purposes, it doesn't look any different to when I started.

Something like this Now breathe a big sigh of relief, because from now on it's all software, with which I'm much more familiar Take a look at the code and you'll see what I mean - you can force the LED to be permanently awake necessary to get a good image , switch it back to normal mode where it will sleep after 1.

Note that the pixel values are all in the range 0 to 63 because two bits of each 8-bit pixel are used to indicate data validity and start of frame - refer to the datasheet for the gory details. Now, almost but not quite the final picture - here is the mouse attached to the Arduino, and all that's needed is to plug the Arduino into the USB port of the computer and try to get some output Just add USB cable You can download the streaming version of the sketch here , but I'm going to hold off on releasing the source code for the viewer for a bit because I have some more cunning plans for it in a later blog post There are plenty of alternatives, of course, like touchpads and trackballs, but they never seem to catch on to the extent that the plain old mouse has.

One interesting variation is the pen mouse. These do rely on a pre-computer analog: a pen or pencil. You can buy them already made and they are surprisingly inexpensive , but what fun is that? The main parts of the pen mouse include a cheap mouse with a failing scroll wheel, a bingo pen, and the base from an old web camera. The project is mostly mechanical rather than electrical. The rest of the build is a construction project.

The result appears to work well. Sometimes changing your computer mouse can be uncomfortable for a while until you get used to the replacement. It may also take some time to get used to new features or the lack of features the new mouse has. He previously modded his old wired mouse to have a rapid fire button using a timer. The new wireless mouse has a 1.

Eventually, he did find a low-voltage variation called the LMC and ordered a few for his project. The new wireless mouse was taken apart in order to find out how the mouse buttons work. In this case, the signal pin is pulled low when the mouse button is pushed. Now that it is known how the mouse button works, just a couple of resistors, a capacitor, an NPN transistor and a push button switch are all that are necessary to finish up this mod.

When the push button is pressed, the LMC timer activates the transistor in order to ground the mouse button signal pin. This happens to the tune of times a minute! Bastille is now working on an app for Android that could find vulnerable computer peripherals in its vicinity. However, there have already been calls for an automatic tool that could be used to exploit this vulnerability by hackers and criminals. Experts recommend to update the firmware of your device or using Bluetooth or wired devices only.
