Binary wristwatch for every nerd

Jordan started this binary watch project to gain more experience in programming PIC MCUs for low power applications. But it turned out pretty successful that after wearing it for about a month he started selling them for everyone. As we mentioned, binary watch is based on PIC18F24J11 microcontroller which drives bright LEDs on display for each binary digit. Having bright LEDs installed he was able to dim them and this save power without loosing brightness. Watch is powered by CR2032 coin cell battery which is enough for 3 months of usage. Special care is taken to make watch as low power as possible by combining several MCU sleep modes. He found interesting solution to watch clasp. He used same programmer ribbon cable and secondary non electrically connected header on other edge of board. It really looks great and there are no redundant parts. Continue reading

Binary digital wristwatch for real nerds

It is said: “There are 10 types of people in this world, those who understand binary and those who don’t”. If you choose understanding side, then you might want to wear binary wristwatch. Building such watch is fairly simple and easy, because you only need few components and even simpler code. Elias watch is based on PIC microcontroller which comes in SSOP-20 package. With few difficulties on soldering it to small PCB he had it running. Watch is powered from coin cell battery CR2032. With smart software solution combined with sleep modes this watch can last long. But the main point of wearing this watch to be identified as nerd. I’m not suggesting to replicate this one, but build your own version. Continue reading

It is Fun to Hack Binary Clock!

Clock is use to show the exact time to the people and can you ever imagine the life without the existing of clocks? Yep, it must be a terrible and horrible situation indeed. Today, you’re very lucky, as you’ll have the chance to get involve hacking the binary clock! Oh, I can sense some doubts here. Ok, I’m going to try my best to clear out the mystery here… For your information, a binary clock is a clock that displays traditional sexagesminal time in binary format. In the very beginning, it only shows each decimal digit of sexagesimal time as a binary value, but it also present in true binary form in nowadays. It’s nothing hard to hack binary clock. First of all, you have to use three pieces of acrylic, and cut a hole on each of them. The top piece has four holes for the mounting screws, where are holding the whole thing together and the “Time to Hack” etch. The extra space on the square piece of acrylic is being used to cut out spacers that can… Continue reading
