External Power Supply



History:

-My plan is to construct an External Power Supply for my Ti-92!
-I have tested my EPS (switch version)and it works perfectly but Iīm still searching for the best way to build it into my Ti-92. Tips, comments and ideas to mr.smile@bigfoot.com.
 

Schematic:

Itīs possible that the layout of your Ti-92 is a little bit different because this plan is only a schematic!!!

Future:

-I am going to built it into my Ti-92
-There will be three version:
 +A "light version": It will only work with rechargeable batteries because the esp will load the batteries while being connected!
 +A "standart version": It will work with the help of a switch, so itīs possibly to choose the way of power supply (EPS or batteries)!
 +A "comfort version": It will work with the help of an electronic switch!

The schematic shows the standart version!!!

If you have any questions, tips, ideas please contact me!!!
