We often think of analog computing as a relic of the past, room-sized monstrosities filled with vacuum tubes doing their best ...

Never miss a blown fuse again! This ultra-simple four-component circuit ensures you’re instantly alerted when a mains fuse fails, using an active flashing LED — no complex measuring needed, just smart ...

The startup is focusing on a type of chip called an optical circuit switch ... "Google is a pioneer. They led the way," said Ming Wu, one of the firm's co-founders and also a professor at ...

For a small kit in a plastic bag like our 555 LED flasher a mid-range padded envelope is fine, even when wrapped in an invoice for mailing it’s not heavy or sharp so it won’t either puncture ...

Note, there is a flasher version ... This is the basic idea of the circuit My cunning idea (now proved to be not-so-cunning) was to have constant current supply to a capacitor and load it with an ...

Note; there is a flasher ... circuit some positive feedback by turning the pnp transistor on, which in turn holds the npn on for a bit (the npn otherwise loses base drive as the cap voltage drops ...
