This circuit operates at a voltage of 1.3 V from a single mercury cell. We found in an old documentation and for the components used the frequency is 500 kHz.
Found on a Radio Electronics, but also on other sources and placed elsewhere in this section, this low...
Here we show how a Constant Current Source can be created in the Multisim Blue using a common BJT...
We found this light-effect circuit with LEDs using the well-known 4017 in a 1987 documentation. All...
