Simple Binary Clock

This project is a kit that is available at www.etsy.com/shop/applemountain and ebay.com/applemount

This is powered over a mini USB connection. It does not interface with a computer, it only leeches power from the USB port.

This is a great project for beginners, or anyone looking for a binary clock to build, or an easy binary clock to mod.

This project took me about an hour to complete.

Step 1: LED Installation

LEDs do have polarity. The bases are not perfectly round. There is a flat edge on the negative side of an LED.

The footprint of the LED is silk screened on the board. Not all of the LEDs are arranged with the same polarity. Check every LED for the proper alignment.

This is the focal point of the project, so we want it to look nice. Once the LED is placed in the board, I recommend a small piece of masking tape to hold it flat on the board while it is being soldered in place. If nothing is holding LEDs in place, they may solder in place at unwanted angles.

Once they are soldered in place, the leads can be clipped off.

Placing the LEDs in the four corners first, will permit an even work environment, and make placing LEDs straight and flush against the board, easier.

I GOT IT, BUT I WOULD LIKE INSTALL REAL TIME CLOCK, WOULD YOU TELL ME HOW. MAY BE WITH DS1307 AND A CRYSTAL.
THE SQUEMATIC WOULD BE GREAT. I MADE IT LIKE A WATCH WITH A 3.7V BATTERY Li RECHARGABLE. OR MAY BE YOU SALE WITH THAT RTC.
I LOVE IT,
THANKS

can you offer a schematic? do i need to program something or is it just plug and use it? thanks

The controller comes per-programed in the kit. It is pretty much a "plug and use it" setup.
