LCD clock with 4 display 1

LCD clock with 4″ display

The time keeping is provided by DS3231 RTC chip with an integrated high accuracy (± 5ppm) MEMS crystal. This makes PCB design very simple, as one does not need to take care on special traces design around the crystal. The chip is powered via the VBAT pin with VCC pin being grounded. This way its

Large 7 Segment Clock

Large 7-Segment Clock,

Since it was one of the first things I ever built, I decided to put it in an enclosure of its own and consider it too as a finished product. The problem was that the prototype never ran properly. It worked, just not as well as it should. Needless to say, I tried to fix

DIGITAL CLOCK CIRCUITS

DIGITAL CLOCK CIRCUITS

A Digital Clock can be made easily by using PIC Microcontroller, DS1307 and a 16*2 LCD. I have already posted about Interfacing DS1307 RTC with PIC Microcontroller. The DS1307 RTC can work either in 24-hour mode or 12-hour mode with AM/PM indicator. It automatically adjusts for months fewer than 31 days including leap year compensation

The holoclock

Minidot 2 – The holoclock using PIC16F88 microcontroller

Minidot 2 – The holoclock 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: http://www.instructables.com/id/EEGLXQCSKIEP2876EE/ and re-using a lot of code and circuitry from my Microdot located here: http://www.instructables.com/id/EWM2OIT78OERWHR38Z/ EagleCAD

6 Digit LED Clock

6 Digit LED Clock

I recently found six 2.3″ red 7 segment displays in my collection which I purchased from Rapid Electronics when they were clearing out non-RoHS stock. Since I have no clock at my work bench I decided to construct one from some prototyping pad board, a Microchip PIC18F26K20 microcontroller and a Dallas DS32KHZ temperature compensated 32.768kHz
