Being not the most diligent of picture taking people, there might be a few gaps in the visuals of this worklog; ah here comes one! I don't have a before disassembly picture.
I have this nice MX1000 wireless laser mouse from Logitech. I used it for about a 2 years, but then the AC adapter for the charging station broke, and it would only work (charge the mouse) after 10 minutes of fussing. Eventually, I found that I could use one of my spare MP3 player's charger to power the charging station. This was still fiddly, but less so than before. Then one day, I walked into best buy with some gift cards and Reward Zone "money" and saw a nice Razer Deathadder for $40 (open box). So I walked out of best buy with a nice new gaming mouse; no batteries, never off, and ridiculous sensitivity and accuracy.
This relegated my MX1000 to being used once every couple of weeks to change settings on my nearly headless SSH server. The last full battery charge lasted over 3 months, and I was still using it to test the mouse during my mod.
There were two problems with my MX1000 even when I bought it:
- Its surrounded by two computers (sometimes 3) a couple monitors, a wireless router, the cordless phone, and a 15 year old microwave. It had major issues with interference.
- You had to charge the batteries, very inconvenient for someone as forgetful as I am. In the middle of a huge research paper: "oh CRAP! my batteries are dead!" or in the middle of a Counter-Strike domination spree having to switch to keyboard aiming.... The Batteries had to go.
And then along came a Mouse Modding competition. A perfect time to fix everything wrong about my mouse.
This is my workspace, an unused portion of the kitchen table.
This is the Mainboard from the Mouse(the ribbon cable goes to the thumb button's pcb):
And the PCB from the base station (sorry no disassembly pics)
The antenna trace on the PCB took up too much room, so I scraped the solder-mask off two points and shorted it with a wire, dropping the resistance a few ohms. Then I cut that section off, taking the Reset button with it (i never used it on the original station anyway... it was worthless)
Now if I was going to move the base station into the mouse, there was nowhere to put the large Lithium Ion battery pack(bright blue rectangle in the first pic), now was there? I needed to power the mouse somehow.... so I looked around and thought: USB! Its pretty darn close to the right requirements. 3.7V 1700mA is close enough to 5v 500mA.... kinda. I decided to throw another USB connector into the mix so I could use 5v 1000mA just in case.
2 plug USB set up: The original Logitech (rounded) connector carries signal and power, the blockier connector carries power only.
The Battery connector
I removed the yellow wire (signal? monitoring? charging?)
This is what the final wiring inside the mouse ended up looking like:
the black 4 pin connector will connect to the base station PCB, and you can see the power cables are split between the mouse mainboard (plugged in) and the original connector.
On to Cometics!
The original color, a bit grimy:
This is my amazing spray station, a wire stuffed into one of the screw holes on the back of the insert, and wrapped around what used to be an awning. That was after the initial 1000 grit sandpapering, and a couple coats of Duplicolor Adhesion Promoter (Clear) (random website, i got mine at Kragen)
Here after a bit of "Deep Jewel Green" paint (also from Duplicolor)
And a bit more:
I managed to get some running on the last coat, so I had to do some sanding, and more coats of color (lighter coats this time). I didn't take pictures of that or the clear-coating for some reason...
After it came down from clear-coating....
And finally I put it all back together, screws and all:
Full power break-in test last night and it works! Also, because I could, I removed the little spring wire that made the mouse wheel click, so now it rolls like the MX Revolution... As fast as you can throw it.
About 2000 pictures, sorted, photoshopped and uploaded say that my new wired MX1000 works a treat.
This is my first serious mod, so thanks for reading, and comments about my writing, or whatever are greatly welcome!
