This dead-bug style 555 blinky light is one of those projects, undertaken just to see how small a circuit can be. Pretty small, as it turns out, and we bet it can get even smaller. [Danko]’s ...

Although not currently as robust as typical printed circuit boards, this research shows that ... soldered circuitry and support organic light-emitting diodes, or OLEDS. Of course, the main ...

The two diagrams above are of the same circuit for a simple night light. How it works: when darkness falls on the light dependant resistor (LDR), its resistance increases causing a higher voltage ...

They’re basically wearable circuit boards. Produced by [Chaotic Moon ... they mount an ATiny85 connected to temperature sensors and an ambient light sensor on the skin. A simple device like ...

In the dark it has a bright green appearance while glowing, but in the light it has an off-white yellowish tint. The Circuit ...
