I have recently been reading about the use of timers on AVR chips over at Max Embedded and thought this would be a perfect opportunity to update my binary clock once again. I decided to make use of the CTC option, whereby it clears a timer on compare, you set a value for the timer to…
Well I finally soldered it all up after finalising the board layout and ironing out bugs in the software. Final Schematic: Final Board Layout: Here are the parts: BOM: 1 x Perfboard 1 x ATtiny44 MCU 17 x LEDs 2 x switches 2 x 10K resistors 2 x 7 pin female headers 2 x 12…
Well I finally wired this all up on the breadboard and left it running for about half a day, but it has some serious time loss issues. As you can see it is running with the internal clock at 8Mhz as there is no external crystal. Writing this then made me realise why it is…
For a while now I have wanted to build a binary clock, simply because they are cool, but not wanted to pay the price of some of the shop bought items. I decided that I would not use the classic binary coded decimal, but instead use binary coded sexagesimal, as it makes use of fewer…
