That's why we make it a point of honour that everyone can express their uniqueness through their style.

Imagine the excitement of reading the time in binary mode, a language appreciated by science and technology enthusiasts. There were a limited amount of ICs that provided such features and one of the cheaper options was the BQ29700 IC. The TPS61220 required minimal external components, was fairly inexpensive and was able to satisfy the current and voltage requirements. This variety, which one might not expect at first sight with Binary watches, speaks to men and women alike.There are 5 LEDs to show the hours, there are 6 LEDs to show the minutes, and there are 6 LEDs to show the seconds (which aren't used in clocks with 11 LED lights). This meant that I had to route all of the traces on a single layer while making sure to keep the "noisy" parts of the circuit away from the sensitive signal traces. Who knows what the watch does on day 365 or the extra day for a leap year which is in week 53 officially. Each part of Logo has been individually designed and manufactured, including the case, strap and uniquely programmed display.

I connected the battery to the PCB and placed the battery and the PCB inside the 3D printed enclosure. Binary-Watch-SK contains: Binary-Watch Kit, plus a metal stencil, plus rubber squeegee, plus solder paste jar of 50 grams (good to solder 20-30 kits). With a mirrored LCD interface, a stainless steel and acetate case and strap, Logo features time, date, alarm, EL backlighting as well as binary time, for the geek within.It is a very small (2mm x 2mm) addressable LED with a wide range of colors and is fairly inexpensive. I am aware that there probably is a cheaper microcontroller that I could have used but knowing that the Atmega328 would have full support for all Arduino libraries was a big factor in choosing it for this project.
