Rapid Fire Mod For A Wireless Mouse

Rapid Fire Wireless Mouse

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. [Jon] bought an awesome wireless mouse that he really likes but it is missing one critical feature: rapid fire for gaming. He previously modded his old wired mouse to have a rapid fire button using a 555 timer. That worked fine as the mouse ran off the USB’s 5 volts, and that’s the voltage the 555 timer needed. The new wireless mouse has a 1.5 volt battery and can not support the 555 timer. What’s a gamer to do?

[Jon] searched around the ‘net but could not find any wireless rapid fire mods. Eventually, he did find a low-voltage variation called the LMC555 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 LMC555 timer activates the transistor in order to ground the mouse button signal pin. This happens to the tune of 1236 times a minute! That is a lot of rapid firing.

The few components were soldered up neatly and packed into the limited spare area inside the mouse. A hole drilled in the side of the mouse’s housing holds the new rapid fire push button in an ergonomically pleasing location.

Earlier, we mentioned [Jon] has done this mod before on a wired mouse. He learned about that project here on Hackaday. Check it out if your wired mouse is craving a rapid fire button.

Simple Xbox 360 rapid fire mod

Back in May we mentioned AcidMods’ spitfire mod that enabled rapid fire (amongst other things) and was undetectable by Xbox Live. The parts list was quite low, needing just a PIC16F84A and a few other components, which led to third parties selling controller mod kits on eBay. The AcidMods team has figured out a new way to enable rapid fire using just a momentary switch and the necessary wire to hook it up. All you need to do is wire in the switch between the ground on the controller LED and the middle pin on the trigger. The only caveat is that because it’s hardwired to the LED, you can only use the mod on the particular port you’re using the controller on.

The reason it’s so simple is because the Xbox 360 controller uses pulse width modulation to “dim” the LED on the controller, creating a rapid high/low signal. When the momentary button is depressed, it routes this rapid high/low signal to the trigger input on the controller, which is then input to the Xbox 360. Hit the read link for a couple more videos explaining this hack.

While this modification is undetectable by Xbox Live, it does create an unfair advantage in multiplayer gaming and could result in your account being banned.
