Place the gear train back in the case, and re-attach the lid. Install a AA battery and hold the movement up to your ear to test it. You should hear it ticking in whatever pattern your firmware has.

If reprogramming is ever desired, you can use a pogo pin programming adapter on the programming interface on the board. If your programmer cannot overcome the coil impedance, use an X-acto knife and cut the trace between the two pads of the jumper block on the bottom right corner of the board. That will disconnect one of the coil wires temporarily. Short the jumper closed with a blob of solder once you're done programming.

INSTALLING THE MOVEMENT

If you buy a complete movement, it will come with the movement itself, 3 hands and a bag of hardware. The hardware bag will have in it a large rubber washer, a small metal washer, a hex nut, a round nut and a round cap.

Depending on your clock or clock face, the movement may be held in place on the back with clips or you may need to use the hardware to attach it to the front.

The large rubber washer goes between the movement and the back of the clock. It's optional - on the one hand it will help keep the movement fixed in place, but on the other hand, it will reduce the noise of the ticking, which is often the point of the Crazy Clock. If your movement does not clip in on the back, then use the metal washer and the hex nut on the front.

The hour hand is a friction-fit. To install it, first take the minute hand and rest it over its stem. It has a rectangular shaped hole. Rotate the minute hand until it points to the 12, then remove the minute hand and set it aside. Install the hour hand so that it points directly to an hour number (which one doesn't matter). Insure that the hand is all the way on its shaft and is parallel to the face. Next, reinstall the minute hand, pointing to 12 as it was before. Use the small round nut (if you do not intend to use a second hand, use the small round cap instead) to hold it onto its shaft. After it's tightened, you can make minor adjustments to the hands, but try to minimize the mount of torquing done to the hour hand.

Installing the minute hand is optional. If you don't wish to use it (for example, for the tidal or lunar clocks), then just install the round cap by itself.

Lastly, if applicable, press the second hand onto its small pin in the center of the shaft stack. Make sure that you install it straight. Press it on firmly, but not too hard. If you use the second hand, you'll have the small round cap as an extra part. You can discard it. If you don't use the second hand, you'll have the hand and the small round nut as extra parts. You can discard them.
