This looks like a lot of fun (and an simple kit to make) - "This very unusual kit emits random pops and random explosions of bright white light when it is in the dark (kit has a CDS cell to sense the absence of light). This kit produces one of the most unusual "out-of-this-world" effects. Features SCR and CDS circuitry with 3 bright lamps and a piezoelectric speaker. Easy to build and creates a spectacular display. It may even cause speculation as to whether or not it was left here by aliens! We put four of these into a darkened room and the resulting sound and display was amazing! Size of PC board: 2.9" x 2.4". Operates on 2 AA batteries (not included). Complete with all parts, PC board and instructions." - Link.

I just purchased this project (thanks to make), but have some questions as I am new to electronics. I've started a discussion thread in the make forums... please check it out, and if you bought one of these too, maybe we can start a tutorial or instructional for it...
