Logic testers are simple but very helpful devices in testing digital circuits. A logic probe can be designed in many different ways. In this particular. ... the logic tester will recognize it as a ...

Light logic doesn’t use the conventional active devices you’d expect such as transistors, tubes, or even relays. Instead, it uses LEDs and CdS cells to make rudimentary switches.

Figure 1: Light circuits. a , This circuit represents a basic two-qubit quantum logic gate. Blue beam splitters reflect 50% of the incident light, green beam splitters 33%.

This is an oldie, but oh, man is this ever good. It’s a Nixie clock made without a microcontroller. In fact, there aren’t any logic chips in this circuit, either. As far as we can tell,… ...
