We found this circuit in an old documentation. The integrated circuits used are specific to produce effects and do not admit equivalents, being currently difficult to find.
The figure shows how to connect a 7400 to obtain a bistable configuration. The circuit must be...
We found this circuit in an old English documentation from the 70s. The transistor can be a modern...
The purpose of the practical circuit shown in the figure is to generate a pulse of programmed...
