Six Digit LED Clock
I have found this kit very useful. I actually don't use it with the AT89C2051 but connect an Arduino small board computer to it in place of the AT89C2051. It is good value as it provides the printed circuit board and all the components I need to provide the LED display and connect to the Arduino.
Using the Arduino I then connect to a NTP server and then have it update the clock display to give accurate time within a second. This clock is used at our community radio station so the announcer can accurately switch into the news service on the hour.

Krone Punch Down Tool - good value
Very nice solid tool. Much better than the cheaper tools on the market.
