When an alternator is used to supply constant current, it needs an adjustment that must be made as shown in the figure. The potentiometers are of low wire value with high dissipation.
The circuit shown in the figure makes use of an LM3909, a low consumption and low voltage IC. The...
This timer circuit was found in a 1980s documentation. The integrated circuit is the 555, which...
This very high voltage (VHT)generator was found in a 1995 documentation. The transistors must be...
