HP C200 Digital Camera Teardown

Teardown of the HP C200 Digital Camera, a 1 Megapixel camera!

Most of the chips in it are so specialized that I couldn’t find any info on them, but I try to go over what I can with it, as well as show how much power it draws.

Custom Expansion Bay Adapter

 

 

Using a USB card reader every time I want to transfer files is annoying. Let’s shove a card reader into my PC with some cardboard!

My PC case only has 5.25in bays, and I have only 3.5in card readers. Instead of buying an adapter, I just make one with cardboard. It sure looks good!

TI-55 Calculator

TI-55 Calculator Battery Replacement

 

How I made my TI-55 calculator work. THE THING HAS AN LED BUBBLE DISPLAY.

Want to breath new life into an old calculator? The TI-55 was one of the best in the line of scientific calculators with statistical capabilities back in the 70’s.

The TI-55 has an LED-stick using LED chips mounted and bonded to the printed circuit board, and has some 12-digits instead of the 9-digits of other calculators from the same time period.

The TI-55 calculator used a rechargeable battery pack rather than using a 9V battery, so when the rechargeable no longer worked, your battery was dead. However, the voltage and current used in the rechargeable works out to be still, 9V capable, so this video shows how one can easily adapt the TI-55 for use with a standard 9V battery.
