Since the device comes out of the wrist strap, maybe you should make a charging dock for it, if you're using a rechargeable battery.

We'll see. As for now there is no space for an internal battery since I used DIP components.
If you like my work: why not give me an internet?

Where did you get your LCD? I'm looking for a small 4 line by 10 character LCD (for my project, which is similar to yours, and my 2 line by 16 character display is just a bit too wide).

My lcd is called nokia 5110 lcd module. I got mine from ebay. There are a lot of people who sell it. Just pick the cheapest one :) Don't forget to check the rating of the seller.

Thank you! My device will be somewhat like yours, but have a simple BASIC-like language on it. Actually, this device will probably be some kind of handheld, so my wider LCD would work. I could have it work with 6 buttons. 5 in the front: 2 soft keys, 2 directional keys (left and right arrow keys) and an OK button. On the side there will be a button that brings up a menu of functions (clock, stopwatch, programming, and system info).

That too will be included in system info. When I get home, i will start programming this. Once I figure out how to orient the LCD correctly on the bread-board :P

It has been a while since I worked on this. I found some nice and flat 3,7V lithium batteries which are perfect for a project like this! However: My wireing job was a mess. I am much more skilled now than I was a couple of months ago, so I'm going to re-wire the whole thing and add the fancy new battery pack. We'll see how it goes.

Good luck with it!
I hope you'll still remember where which wire goes :P
And I hope the battery'll be worth it :)

The battery was inside a gifted 3rd party ps3 controller, so of course it's worth it!

Cool to hear. You should post more pics of it or maybe a video of it in action when ready for showcase :)

That really sounds awesome. I'm impatient to see it in a finished state. :D
