binary pocket (now wrist) watch
Moderator:Moderators
Hey guys, I haven't posted here in ages, but I've finally finished a new project: a binary pocket watch! I figured that's portable and geeky enough to be appropriate here.
And here's some pictures:
This is using a chip intended for nixie clocks because I'm too lazy to program my own microcontroller. It runs on 4AA batteries, which will hopefully last a while.
The time displays when you hold down the bottom button, and the 2 on the side are for setting the time.
Here it is turned on. It's 12:06 because I took this picture before setting the time.
The back is an embarassing mess of chopped up ide cable.
Looks pretty cool in the dark.
And here's a chopped up nimh 9v battery I'm considering using to make it a wristwatch, albeit a really huge one.
I'm pretty sure this is the coolest thing I've ever made.

Optomists say that the glass is half full.
Pessimist say that it's half empty.
Engineers say that it's twice as big as it needs to be.

That is pretty cool.
Give it a tinted glass cover so that only lit LEDs are visible.
Also, try powering it with a 9v button cell or two.
AAs are TOTALLY overkill.

omg! the back, I don't know how you stand doing that without color coded wires, I mean come on, it is so much easier to follow a wire of a different color than a gray one in a tangle like that

It really wasn't very hard to keep everything organized since it's so small. I didn't even go in any particular order. Though I did occasionally have to desolder and move some wires out of the way temporarily because they covering up something I was trying to get at. And I forgot to attach the top left LED, but it never lights up anyway.

I replaced the batteries with 3 nicd AAAs (cuz I'm too cheap to buy nimhs), and added some pin headers to attach a (currently nonexistant) charging cable to.

Too cool,man. Too cool. I like the USB idea. I like the whole thing in general. And nice sig.

I got the sig from a 10 page packet of engineering jokes my dad brought home from work one day. Guess it runs in the family...
I finally made a charging cable once the battery died (only lasted 2 days ). I ended up hooking it up to an RC battery smart charger, which can fully charge it in ~15 minutes. And I'll probably pick up some nimhs the next time harbor freight has them on sale. Those should last 4 or 5 days.
And there's another slight problem: it occasionally resets the time to 12:00 for some reason. Dunno why that happens.

Re: binary pocket (now wrist) watch
you can put the squematic and the hex file and program asm or c for made some for me thanks for help me
