Well maybe holoclock is a little bit inaccurate....it does use holographic dispersion film on the front to give a bit of depth.
Basicaly this instructable is an update to my previous Minidot located here:https://www.instructables.com/id/EEGLXQCSKIEP2876EE/
and re-using a lot of code and circuitry from my Microdot located here:https://www.instructables.com/id/EWM2OIT78OERWHR38Z/
EagleCAD files and Sourceboost code is included in the zip files attached.
Why? The previous Minidot was overly complex, from the Microdot I learned how to do an RTC on a PIC using only a 32.768 crystal and didn't need to use a special RTC chip. Also I wanted to get rid of the display chips from the previous Minidot. So now there is only a power regulator chip and a PIC16F88....just two chips.
The other reasons for an update were my Minidot was getting a bit un-reliable because of the seperate switch board and I wanted a soft fade between dot patterns as well as some sort of ambient light sensor to dim the display at night. The other Minidot was fixed brightness, and illuminated a room at night.
The device was constructed with the aid of the EagleCad software package and Sourceboost compiler. You'll need to have some experience with electronics and programming PIC controllers to start this project. Please note this isn't an instructable on either electronics or PIC programming, so please keep questions relevant to the Miniclock design. Refer to the instructables above or many other instructables on this site for advice on using EagleCad or programming PICs.
So here it is.....Minidot 2, The Holoclock......or Minidot The Next Generation.............
