Caller ID/telephone/alarm clock
The product:
Dual-alarm clock/telephone with caller-ID.
Our customer's need:
Design it for them.
Our solution:
Using a low-cost 4-bit controller and an FSK receiver IC, design a circuit which
operates as a combination caller-ID box and dual-alarm clock. Display the clock time
on the LCD, replacing it with caller-ID information when calls come in or when review
buttons are pressed. Offer several different alarm options independently for each of
the two alarm times.
Our involvement:
We designed the electronics and wrote the firmware.
