[roelh] has built a flip-flop circuit using only one transistor and some ... The weirdest, by far, is [Ted Yapo]’s Diode Clock, a digital clock made with diode-diode logic.

It is made by adding a potential step, which emulates a semiconductor junction (the boundary between p-type and n-type solid-state materials), to an energetically-flat optical lattice Atomtronic ...

If you have an analog VOM, you may be surprised how high the short circuit current is on the Rx1 range. Mine runs 120mA. Note that this is sufficient current to destroy a sensitive germanium ...

[Hales] has been on a mission for a while to make his own diodes and put them to use and now he’s succeeded with diodes made of sodium bicarbonate and water, aluminum tape and soldered copper.

This differs from the circuit shown in Figure 1 by not only the value of the limiting R but also the 2.2kΩ protects from voltages above +Vs. This is an example of the intricacies that must be fully ...

Innovations such as quantum thermal diodes, capable of directing heat flow ... behavior can be effectively captured and explained using a simplified, yet powerful equivalent model composed of ...

The drain voltage reaches about 2 kV using this test circuit when the snubber is removed and avalanche does not occur. If the snubber diode is conducting reverse current when it turns OFF ...
