A previous Design Idea describes a circuit that uses an astable multivibrator to drive an LED (Reference 1). The circuit in Figure 1 uses a simpler alternative approach. The circuit uses a 2N3904 NPN ...
My teacher friend was looking for Christmassy technology ideas for a science + engineering club. And I said that flashing leds might be good, and if you can get three phases going, you can have a ...
While choosing an op-amp buffer, some sources of negative supply were considered, because the buffer op-amp had to provide true zero voltage on its output. In reality, a typical rail-to-rail output op ...
