Apologies if off topic, but I have searched google and found nothing...Perhaps someone here can lead me in the right direction... I am looking for the following...an LED or LCD minute clock ( just 2 digits)
4-6 inches in height and is high visibility, prefer AC power.Perhaps a link to a kit or schematic so that I can build it myself.
Thanks for any info. Brandon

Google "digital clock schematic"
and another from this newsgroup
Digikey makes large LEDs of about 5" that come in red or green, CA or CC. They're not cheap at US$38.70 each. Then all you need is a few logic IC's or a microcontroller and some drive power of 40 to
60mA/segment continuous or PWM'd at up to 180mA/segment. Some cheap transistors and resistors would take care of the LED driving. I would use a microcontroller such as a PIC rather than fuss with discrete counter and decoder chips, but I'm prejudiced like that. ;-) For a power source, I recommend you use a regulated wall wart that's capable of putting out about 10W (5V at 2A).michael
Thanks for the replies folks. I appreciate your time and efforts Brandon
