Fi-enabled wall switch that lets you control traditional light fixtures with your phone, voice, and other smart home devices.

With the addition of a homemade dough that substitutes sugar for salt, the dough becomes resistive instead, and complex circuits can be created to power all kinds of objects. We use battery packs, LED ...

Electrical synaptic transmission relies on neuronal gap junctions containing channels constructed by Connexins. While at chemical synapses neurotransmitter-gated ion channels are critically supported ...

The circuit itself is quite simple, especially because it uses an Arduino. You could accomplish the same thing with a 555, but that ... then the two LEDs will be lit. We love the frosted acrylic ...

[Danko]’s minimal circuit is about as small as possible for the DIP version of the venerable 555 chip. The BOM is stripped to the bone: just the chip, three resistors, a capacitor, and an LED.

Ready to turn your house into a smart home? Replacing your dumb bulbs with smart ones is perhaps the easiest way to start. Many smart bulbs can be screwed into existing light sockets, and they can ...
