resistors

It's currently much simpler, supporting just resistors, inductors and capacitors, but it's very useful for teaching students electronics.

These cubes could be thought of as integrated circuits but were actually composed of discrete transistors, resistors, capacitors, etc.

Now days you are stuck with an smd board with multiple microchips and tons of miniscule resistors.

Did you have to use any passive components in your design (like resistors or capacitors)?

Or to find the resistance between two points on an infinite grid of resistors.

It might still be possible to use series/parallel constructions to cancel out the 5 and still save resistors vs' some other numbering scheme.

I think by rainbow color codes the OP was referring to the color codes on through-hole resistors.

Some (all?) amp designs place resistors and capacitors in the signal path.

The proper electronic components transistors/resistors/LEDs not as dominant as you might expect.

Finding that resistance in the grid of resistors involves performing a computation.

The second reason is that it may have picked up some of my mistakes such as transposing the outputs or missing off some pullup resistors.

For some reasons this reminds me of the somewhat common hack of soldered together resistors attached to the parallel port used as a simple DAC.

By this line of logic a "real programmer" should be soldering wires or building their own CPUs and resistors.

Reliable printing on curved surfaces wasn't possible at the time when "miniture" resistors were being produced, and a paper wrapper would be an undesirable extra element.

Discrete electronic components (resistors, capacitors, transistors, simple ICs and sensors, etc) are sort of the "assembly language" of electronics, but the vast majority of programmers never touch assembly.
