Maybe SparkFun would be willing to add some under $20 products or a $20 gift certificate to the list, which would then be allowed.

I always used the water analogy.
- Resistors are pieces of skinny pipe.
- Inductors are long lengths of pipe, it takes a bit to get the water flowing, once the water is flowing it has momentum and doesn’t want to stop (which is why you have water hammer arresters in your plumbing).
- Capacitors are tubs or tanks with a membrane in them (like the one that protects your water heater from over pressure). You can push water through, but as the membrane stretches it gets harder until none flows. Release the pressure and it flows back out because of the membrane.
- Diodes are check valves, water only flows one way.
- Transistors are just water activated valves, a small amount of water will turn the handle allowing a large amount to flow.

I still have a mystery I’ve haven’t figured out. When the batteries in your flashlight are half-dead and dim, why does whacking it help, if only briefly? It clearly does, but why?
“Wire color = Different action?” Sometimes it DOES. Why is enameled wire used in coils? And of course if parts of the insulation are black and crispy, there is (now) a different function of the wire inside compare to other wires….
I didn’t have a TRS-80, but the local Radio Shack would let me work on their display model if they didn’t have any customers, so I’d ride my bike 10 miles to the store and work on theirs.

I’ve never had a problem of finding the replacement items for retired product, the big, bold link that says “This item is retired and has been superceded by this new item” was always pretty obvious.
No public wish lists :(
