special timer circuit - Electrical Engineering
I need a miniature circuit designed (and possibly built) with an LCD digital clock timer display (showing both date and time) that does the following: Push a button and the correct date and time freezes and pulses on and off (although the time display freezes, the internal clock keeps running and keeping accurate time). When the button is pushed again minutes or hours later, the new,correct time freezes and pulses same as before. Must be small voltage battery powered. Also, digital clock must have a date and time manual reset function built in. ------------------------------------------ Added 9 FEB 2012, 7:35 AM EST Note additions and changes to project description: 1.) Entire miniature circuit (except battery) must fit within an area of 2cm x 3cm x 4cm. 2.) Clock display must be on 2cm x 3cm side. 3.) Battery to be 3v coin cell type ( CR2032 or similar). 4.) CHANGE push button (date and time freeze) to a gravity switch (activates only when circuit box is turned upside down). 5.) Must have a red, LED low battery indicator within circuit. 6.) Must submit working prototype with schematics. Everything else in project description remains the same. Desired Skills: Electrical Engineering, Integrated Circuit, Electronics, Circuit Design Keywords: Electrical, Electronic, Circuit, Engineering, Integrated, Design
