    Default What happens when you give me a "Snap Circuits" set...

    There's this children's toy called "Snap Circuits" that has electronic components attached to plastic blocks with metal "snap" buttons on them. The point is that you're supposed to connect the parts in different ways as shown in a little booklet, and watch the blinking lights or make a radio or whatever, and you might learn a little about electronics.

    (see first picture)

    Well, this is what happens when I get into stuff like this:

    (see second picture)

    I'm not 100% sure, but I think that's a switching power supply. There are no plans to build this in the manual, which might be because it generates voltages high enough to deliver an uncomfortable (but not painful) shock when under no load.

    Unfortunately, I think that's what an EE would call a "mess".

    Those look like fun though. When my niece and nephew are old enough and come back from Japan (it's a military family), I might give them a kit.

    I wonder if it has a 555 block? You can make a 50mA DC voltage doubler with one of those. One of the first "PSUs" I built.


    EDIT:
    This schematic:


    You get better results with schottkies than the 1N4004s they suggest; less diode v drop. The 1nF cap can be 10pF to 10nF, anywhere in-between, and still work. The 22uF serial cap can also be a bit larger, but don't go higher than ~100uF. The other 22uF cap can be anything; I used a 470uF. It's for ripple, so ESR is more important than capacitance.

    No, but there is an 8-pin DIP socket block. It's designed for a PICAXE IC (in another kit), but a 555 should fit. The markings just won't be correct.

    I've always thought these things were cool, even if I did have the old 300-in-1 radio shack electronic kits. What I'm really curious about now, is because of the layers, couldnt someone make a processor... Forget this nm cpus, the future is in cm cpus the size of rooms!
