During the New Year Show Ken soldered a component tester. Unfortunately this did not work.
NYBill offered to fix it and he succeeded in his show hpr2591 :: International Troubleshooting. When he shipped it back he included two 555 timers with the message: Now, figure out how to make LED's blink with those 555's!
In this show Ken uses the online guide FLASHING L.E.D. USING 555 TIMER By Trilesto to do this.
