Ultimate Nerd...

Post by EcoTeam » 04 April 08 6:09 pm

Gawd, I haven't been on here forever... I almost forget what caching is! :lol:

Totally un-geocaching related, but I thought a few of you might like (or laugh at) my latest gadget:

Yes, I am the world's ultimate nerd, and now have the gadget to prove it!

Yep, much nerdier than my old Casio DB-102!

Did you get one of those MSP430 watches at a TI MSP430 Day a few years ago, Dave?

They weren't as sophisticated, of course (mainly lacking the buttons) but were still pretty cool. I've got one going into a midnight-only cache sometime Real Soon Now...

So, what's it based on? An MSP430 or a PIC?

It's a PIC 24FJ64. The actual schematic is the background pic.
Didn't go to the MSP430 days, haven't heard about that watch. Got a pic?

That's like the proverbial piece of sting question :shock:

First prototype from concept to working prototype was about 30 hours work all up. Not much at all.

How long does it take to actually make one? A few hours work I guess.

Here's a crappy phonecam shot of one:

At the MSP430 Days, I usually ran one of these off three lemons with copper (20c coins) and zinc (galvanised iron) electrodes, just to show that it was really low power. One's been running off a 2032 battery for almost 5 years now.

Hey, what's the LCD used in that one? A custom thing? or something off-the-shelf?
That one looks to be 8 characters plus some extra stuff?

Would love to know more details about this!
