I used a TLC555, but any 555 should function OK. In this circuit, the 555 timer is applied as a Schmitt trigger driver. This circuit detail is further described in the previous article: 555 (TLC555) ...

The signal is then passed onto a 555 timer configured as a Schmitt trigger that (indirectly) drives the led strobe light creating animation that is synced to the speed of the turn table.
