    My biggest memories of the 150 in 1 electronic project kits is a hand-me-down with missing parts, where any project was hit-or-miss whether I'd be able to complete it successfully.

    If i had all the time in the world, i might try implementing some of the circuits in spice. Of course there would be limitations. I don't think spice can receive radio transmissions. :-)

    Can you also simulate the little springs with one or two strands of the wire connected and other strands snapped? The 150 in 1 kits had some special properties like this. :)

    Ha! I do remember the original stranded wires and the springs, which would make a little twang if you flexed then let them go. After the technician worked on the phone box down the street, i would check out the ground there
    and collect solid copper wire scraps. They remind me of the individual conductors in twisted pair Ethernet cables, except i remember the colors
    were predominantly blue and orange, no green and brown. Kind of like in
    this diagram. Seemed to work perfectly with the 150 in 1 kit. The part
    that makes me cringe is that i used to strip off the insulation using my
    teeth.

    Precious, precious wires! I know exactly the kind you mean. I feel like I became jaded later on once I realized how cheap it was to buy literally HUNDREDS OF FEET (or many metres!) of wire and stopped collecting the scraps. :)

    It felt novel at the time, similar to those Science
    Fair 150 in 1 Electronic Project Kits.

    I used to buy thousands of feet of cross-connect wire when I was a telecom manager - pretty sure it was the same guage as the wire in electronics kits, maybe a little thicker.
