Simple circuit indicates a low battery
The Design Idea indicates a low-battery condition in an audio test instrument that is powered by four AA cells. As the instrument was otherwise an all-discrete design, this same approach seemed more in keeping with the spirit of the project than the use of a single-sourced integrated circuit...

Build Your Own Personal Drone
When I was a boy I loved flying model airplanes. I’d laboriously build them from balsawood kits; cover them with tissue; and add a noisy .049 gas engine. Then I’d go to the neighborhood schoolyard and get dizzy flying them in endless circles at the end of control cables. Today for under $100 you can buy a Styrofoam plane with a battery-powered engine and wireless remote control – a cheap radio-controlled aircraft. I bought one recently and took it to the neighborhood schoolyard where my son and I had a lot of fun with it...

Toshiba Introduces New Low-Height Transistor Output Photocoupler
Toshiba America Electronic Components announced the launch of a new transistor output photocoupler in a low-height SO6L 4 pin package – the TLP385. With its low-height of 2.3 mm (max), 45 percent lower than DIP4 packages, the TLP385 can be used in situations with strict height requirements. Applications including motherboards, programmable logic controllers, AC adapters, I/O interface boards, inverter interfaces and general purpose power supplies are suited to the new photocouplers...
