This circuit is from American documentation from the 70s. The circuit makes use of the operating system of the time, but it can be implemented with more modern equivalents.
The load current can be adjusted up to about 1 A. The transistor can be TIP32 or TIP42. The...
With this step the motor is energized when the TTL or CMOS input is high. Motors up to 1 amp and...
The diodes on this power supply are 2.5 V x 1000 V. The circuit provides a very high voltage for...
