QS's Blinkie Thingie

While waiting to verify the result of my Solar Charger, I starting thinking about ways to use the fully charged CR2 lithium rechargeables I had.

  I came up with this 'thing', which just sits there and blinks, so I'm calling it my 'Blinkie Thingie'. Using just an inexpensive 74HC04 Hex Inverter, it provides a Color wheel or maybe a disco light for small pets.

Step 1:

Here is a short clip of it in action:

your notation for parts leaves something to be desired The battery and battery holder are not included; and, R1-R3 use nomenclature that makes this instructable less approachable. Otherwise, this is completely awesome.

Hey can you help me with the IC's

I was looking at the parts list, and I noticed it needed 3 resistors all over 7.5m. Can I substitute these for all 1m? I have about 40 1M resistors, but none higher than that.

Where do you connect the batteries?

The IC chip has a (+) and a (-) connection on pins 7 and 14. That's where the battery connects to.

Hey, that works, too.  I've never been able to get glue to stick well to PVC, though.  This evening I made a holder from a single AA cell holder (from Radio Shack) and a spacer.  The spacer is a 4-40 by 1 inch screw, two washers and three nuts.  Works, but it's longer than I'd wanted it to be.
