During the New Year Show Ken soldered a component tester. Unfortunately this did not work. 
</p>
<p>
NYBill offered to fix it and he succeeded in his show <a href="https://hackerpublicradio.org/eps.php?id=2591">hpr2591 :: International Troubleshooting</a>. When he shipped it back he included two 555 timers with the message: <em>Now, figure out how to make LED's blink
with those 555's! </em> 
</p>

In this show Ken uses the online guide <a href="https://www.instructables.com/id/Flashing-LED-using-555-Timer/">FLASHING L.E.D. USING 555 TIMER</a> By <a href="https://www.instructables.com/member/Trilesto/">Trilesto</a> to do this.
