- orthecreedence 11y agoI think relays are a lot slower in general. They are more binary as well, being either ON or OFF, where a transistor is actually amplifying a signal based on its input (so it's possible to have a transistor output a range of voltages, between the current of its main source and pullup resistor being used to drag the off state to 0). Not sure how that affects in total, but I think using transistors lets you vary the voltage needed to drive the system without switching out all the transistors.
- JamesNewman 11y agoI never really thought of using relays, just not into them. There's a chap called Harry Porter someone mentions below who has built a processor out of relays which looks very impressive. My starting point was that I was trying to learn about transistors and was looking for ideas of something to build.
