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.┬áConfusingly 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?

      1. Well stay tuned and perhaps you will.

        My interest is in building one myself. I’ve prototyped a 12 hour version with an am/pm led but I quite like the 24 hour version, if I can read it correctly.

  1. 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.

  2. 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.

  3. 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)
