Shown above is the Christmas tree version but it is the same for the other versions. It mounts on the side without the picture on the silkscreen. Ensure pin one is oriented correctly.

Again the Christmas tree version is shown. The Easter Egg version is different in that it has two battery holders. Note that positive and negative ends are pointed out and the positive end of the battery holder is the one that has the square back.

Shown is the Christmas tree version, but the other versions are very similar. All resistors are the same except for the timing resistor with is 10M Ohm.

Again shown is the Christmas tree version, but the other versions are similar. The are two capacitors one polarized (the timing capacitor) and the other unpolarized which is connected to the control pin. See the schematic for more specific information.

Again shown is the Christmas tree version, but the other versions are similar. It can only be placed the correct way as far as I know so, place it where it is in the photo.

The LEDs listed in the necessary parts are for the easter egg version and shown is the Christmas tree version which uses different ones. Either way, using lights with a voltage drop of 2V will work well.

The YouTube video that I shared in an earlier post shows how it works. Keep your eye out for posts going deeper into the math of how it all works, but for now you can check out the schematic that was previously loaded for that math.
