It normally takes two transistors to build a blinker circuit (in order to make positive feedback possible). However, you can also use a photo-resistor (LDR) that is illuminated by an LED. The feedback ...
Fairchild Semiconductor has introduced a programmable LED blinker, the FAN5646, which is designed to eliminate the need for a microprocessor to be in continuous operation mode. The new device enables ...
Description: LED Blinker is an Android app that aims to make it much easier to help you figure out which notification is which. Using the LED light on your Android device, you can choose from a range ...
/:16 While your computer has on-screen ways of notifying you of new email, IMs, and other messages, they aren't much use when your display is asleep. DIY web site Instructables show us how to create a ...
[Eric Wasatonic] had a box of SWB2433 transistors that he had very little information about. In order to discover their properties, he fired up his curve tracer to compare these transistors with more ...
