If you need a precise time, you could use a microcontroller. Of course, then all your friends will say “Could have done that with a 555!” But the 555 isn’t magic — it uses a capacitor and a comparator ...

LTspice makes it easy to create and simulate schematics quickly. Sometimes the best starting point for hashing out a design is to use ideal circuit elements. However, a circuit designer will need to ...

If you enjoy simulating circuits, you’ve probably used LTSpice. The program has a lot of powerful features we tend to not use, including the ability to make custom components that are quite complex.
