Through the TTL output this circuit can be used as a shield. The sensor is a platinum probe, and the operational amplifier can be replaced by a modern equivalent, preferably of low voltage.
This shield or interface makes it possible to control power loads connected to the power grid from...
This circuit is ideal for creating a source that allows the use of automotive power devices on a...
We found this circuit in a 90's Radio Electronics. The circuit can still be easily assembled as all...
