DIY Pocket binary Alarm Clock

Binary Alarm Clock provides an original and innovative method of displaying the accurate time. Instructables member linux-dude shared his compact binary alarm clock that uses an Arduino Duemilanove (which fits perfectly in the tin) to keep time and control the indicator LEDs. The LEDs are arranged in two rows as you would expect, representing hours and […]

DIY LED based Analog clock

Hackedgadgets member Alan Parekh shared various versions of LED based Analog clock. You can build your own analog clock using the following materials: One homemade clock uses a PIC16F877 Microcontroller with a 20MHz clock, it also has a DS1307 real time clock with battery backup. 169 x 700mcd diffused white LED’s connected in a matrix […]

DIY LED Clock

You can build your own Atmel ATmega16 microcontroller based LED clock. The open-source softwares like interactive printed circuit board (pcb) editor and schematic capture program/tool like gschem can be chosen for your design. A Geekysuavo member shared the circuit schematic, layout and copper etch pattern. The required bill of materials can be collected from here and the […]

Radio-controlled LED clock

A radio clock or radio-controlled clock is a clock that is synchronized by a time code bit stream transmitted by a radio transmitter connected to a time standard such as an atomic clock. You can design your own radio-controlled clock using DCF77 atomic clock. To know about DCF77, it is strongly recommended to visit the […]

Crazy Hard Drive Clocks

  Hackedgadgets member Alan Parekh shared some amazing works on hard drive clock designs. Various designs are: Alan Parekh Hard Drive Clock Jason Amsel and Konstantin Klitenikfrom Hard Drive Clock Ian Smith Hard Drive Clock Waldeck Schutzer Hard Drive Clock (translated version) Baidu Hard Drive Clock  (translated version) You too can build your own design with […]

Cool LED clock with Analog readout

You can build an amazing LED based clock where both analog and digital signals are involved. This ‘mixed signal’ based clock has an analog readout, with all the digital signal processing involved.  Dos4ever member Ronald Dekker has shared his design so called as ‘A Mixed-Signal LED Clock‘ can be taken as a reference for you […]
