Introduction: Rapid Fire Mouse Mod WITHOUT Adding an Additional Button
I did an rapid fire mod to my battered Logitech MX500 mouse. There are many howtos around, i used this one: www.instructables.com/id/Add_a_rapid_fire_button_to_your_mouse_using_a_555_/
The difference in my approach is: I did it without an additional switch. So the mouse is not cutted and the mod cannot be noticed from the outside. It is a clean mod.
But the circuit does need a button to activate the rapid fire, i used one of the existing buttons of the mx500.
See the pictures.
Step 1: Overview
Step 2: The Button Used
The Picture shows the button i have used for rapid firing.
I desoldered it and interrupted the circuit points with a piece of electrical tape.
(The red piece on the left side)
The two soldering points on the right side of the button were originally used by logitech for keeping the button in place. I used these to connect the wires. One wire is coming from the rapid fire circuit, the other one is going to the left mousebutton switch. (See next step)
Step 3: The Switch
The picture shows the downside of the left mousebutton switch.
The cable comming from the rapid fire button is connected to the pin on the right.
So when the rapid fire button is pushed, the rapid fire signal goes straight to the out pin of the left mousebutton.
Step 4: Summary
The button for rapid firing is a button i never used, so i added a nice little feature to my mouse, without altering its look and feel.
My little instructable ends with some pictures just showing the circuit which is explained elsewhere.
