Logic probe is circuit that indicates the logic state of the node of any TTL logic circuit. It will work if we must supply the probe with the same power of the circuit that we want to analyze, in other words same Vcc and same GND. The “Test” wire of the probe must be connected to the desired node of […]

We can use a voltage-controlled current source to implement a laser diode driver. Compared with a a Switched (PWM) drivers, this simple linear laser diode driver provides cleaner drive current. Here is the schematic diagram of the circuit: As the basic of this laser diode driver, this circuit uses a Howland current pump with a current booster. The output of […]

To optimally control the charge and hold cycle for sealed lead acid battery, UC2906 series of battery charger controllers is used by all of the necessary circuitry. These integrated circuits control and monitor both the output voltage and current of the charger by way of three separate charge states; a precision float-charge, or standby state, a controlled over-charge, and a […]

To get a position control that are low cost, accurate and simple we can use stepper motor. To drive it we can use a circuit mounted close to the motor, and to control it we can use remote control circuit via long cable. The power for both motor and the driver circuit is carried over two wires the same wires […]
