Prove Your Geek Cred With A Binary Watch

Binary Wrist Watch

After just one prototype, [Elia] has finished his super awesome Binary Wrist Watch.

He designed the PCB in KiCad, using a template for the PIC he found in a standard library — unfortunately it turns out the SSOP-20 PIC footprint in this library was actually a TSSOP-20. Confusingly enough, there was also a TSSOP-20 footprint in the library. Luckily it’s just a few millimeters off so [Elia] was able to just bend the pins in a bit before reflow soldering it in place.

The trickiest part of the project was actually making the wristband. He tried several different styles before settling on a paracord braid design he found on Instructables.

We especially like his quote at the end of the project:

Although not having worn the watch in the presence of normal humans, I can already guarantee that now everyone will be able to easily identify me as a nerd.

Acceptance is the first step in realizing you have an addiction, right?

    Cool, I always liked those. I especially liked the one on HAD last year that had a POV mode that when you swept your arm, displayed the numbers for non-nerds. It had terrible battery life though.

    Side note, I will never wear a cloth watchband again (I believe the paracord falls into this). It’s like a sweatband that has to be removed from the watch whenever it needs washing.

    I’d hate to try to get one of these through the TSA.

    Pretty cool. Most commercial ones are damn near the size of hockey pucks and way too unwieldy to wear often. This one looks a better size.

    Msp430 vs PIC. I know Elia was just wanting a project to use to get familiar withe the PIC family, but who currently holds the low power crown, TI or MicroChip?
    (btw – top row 6 bit hour, bottom row 6 bit minute)

    Looks great! Does not surprise me in the slightest the problems with Kicad libraries though.

    I don’t see how to read the time.
    How does the first and second row interact?
