    I saw this kit recently, It’s really cool but for a college student like myself It’s a bit expensive.

    I made a clock bomb when I was a kid that used a 1 lb. can of black powder (filled with sand)with curly wires coming out of the lid to a small pcb with a junk lcd watch on it. It scared many people who visited my room. After I had left for the Marines, my mother found it and was freaked out.

    I build my first clock back in the 70′s from parts
    and a homemade circuit board.
    At 29.00 UK this one you’re selling is a tad pricey.

    i’m not selling this, i bought it myself and reviewed it.

    I have been looking for an interesting clock kit to buy as a gift and I really like the look of the Nixie clocks, but they’re so expensive. This one, at $70 US dollars after s&h seems a little pricey too. Do any of you know of a similar kit around the $50 or less range?
