Multifunctional alarm clock with internet connectivity

We continue to go through circuitcellar 2007 16-bit PIC design contest. Next project (second place winner), developed by DJ Delorie, is a cool multifunctional alarm clock that is connected to internet. Along with cool look of this clock it also has several nice features like automatic time setting on power up, can play streaming MP3 music and of course clock can be remotely managed from personal computer that is connected to internet. Alarm clock runs on PIC24FJ64 microcontroller. Internet connectivity is made through ENC28J60 IC. Clock also is equipped with graphical display, volume control and seven buttons for local control. Full project files are here. Continue reading

Math alarm clock will wake you up in the morning

If you have problems with waking up in the morning- this alarm should help. This alarm clock isn’t so easy to turn off as it requires some brain action. Alarm clock is equipped with LCD screen where a math problem is displayed when alarm is triggered. So you have to solve a problem like 23×17+6 in order to turn off and alarm. Project is based on PIC16 microcontroller. Project is presented as open source. Download source code and project files including schematic and PCB, if you want to build one for yourself. Author also provides suggestions for improvements like adding backup battery, or single chip radio. Really cool project that can be made from parts available around. Continue reading
