Default Re: Turntable Stroboscope

After a somewhat lengthy diversion to build a Raspberry Pi Wireless Print Server, now deployed and working, I'm back to looking at the 300Hz strobe.

I carefully followed the design for a Typical crystal oscillator circuit shown in the HEF4060B Product data sheet (page 8) and wired up all the required components on a Breadboard - see attached picture.

Couple of questions though: -

1. Will 4.5V be enough to get the whole thing oscillating?

2. How will I know that it is working at this stage before I go any further?

Thanks in advance...
