For testing old Computers you will need a lot of different power supplys with AC and DC Voltage.
I put them together and we got one to rule them all 
Meanwell RT-65B and a 9V AC Power Supply
9V /2100mA
5V / 5,0A
12V / 2,8A
-12V /0,5A
So it works @:
I used a Competition Pro USB (bad USB lag) and changed it into a UWRC Controller.
It uses Button, A,B,Select,Start (on the triangle Buttons). With the small black switch you can select the triangle Buttons between Select,Start and Button X,Y.
I bought some Competition Pro Mini and most of them have brocken microswitches 
I found some replacements here:

It was very tricky to add the Universal TX PCB in this tiny stick but after all it looks great 
After removing original parts I add a Led and two more micro switches for Select and Start.
The chrome switch to swap between Layout Select/Start and Button X, Button Y
I must move the electronic of the LiPo to put it between the two fire Buttons
I want to make a wirless optical mouse with the authentical look and feel
For this I Used a small PC optical Wireless Mouse.
Opened it removed the uneeded stuff and take a amiga mouse with the help of some dremel it fits into it
Here you can see some pics from the progress
Have fun
you can use this mouse at PC via USB, Amiga via Jerry Adapter, Atari ST via Jerry Adapter
3 in 1 Mouse
I want a Amiga 600 in a like new state but the common prob is yellowing over the years
With cleaning and some retrobright fluid I done the following:
First a lot of work, to dissasemble the amiga and keyboard *puh*
Have a look to the yellowed ASDF Row…
After this cleaning in Dish Washer, Brightener for 9 Days + a lot of SUN.
Reassambling, and it looks like new:
Have fun
My goal is to have a good Amiga Mouse working on every surface and without needing of a mousepad.
The only solution is to make it optical.
After some research I found a mini optical Notebook USB Mouse and tried to rip of the original amiga mouse:
(The black box is a complete PC USB Mouse)
I removed the optical stuff to make room for the optical mouse:
Now its time to open the tiny PC mouse:
pcb only :
For testing I am using some tape to hold the lens in right position. The final version will hold via clue:
The USB Cable Connector is to big. Instead I found some better solder points for direct connect of a cable:
for fitting into original Amiga Mouse you need only to remove this pcb peace:
here you see how it fits. brown and red wire are left and right button signal
brown and red wire to the buttons and a ground wire and some screws to make it hold:
I changed the USB cable to make it look more authentical
openend the original cable holder and placed it to the usb cable
some clue and pressure
and now it looks like a real amiga mouse with cable but its working on PC
and with the help of this little device from Pawel Burdzy http://www.ebay.de/usr/electronika4you
it is working on amiga too
you can order it here
