The core element of any electronic device is the power supply. Any instability or malfunction of the power supply causes the device to malfunction or demonstrate weird behavior. In some sensitive applications, we need a dual voltage-rail power ...
Replace your old 78xx voltage regulators with this much more efficient pin-compatible buck converter. Efficiency test. 7805 replacement. Input: 12 V. Max power: 11627 mW. Max efficiency: 93.2%. Efficiency test. 7805 original (L78S05CV). Input: 12 ...
It is often difficult to design an effective thermal-management scheme that minimizes the risk of meltdown or fire. System orientation, placement, or both complicate matters by generating hot spots at varying locations on a PCB (printed-circuit ...
An inexpensive piezoelectric wafer is used to detect vibration and when the vibration is sufficient a switch is activated. Materials on the topic Datasheet Texas Instruments CD4069UB discovercircuits.com
An ultrasonic range finder is a useful tool in a variety of real-life and robotic applications, such as in obstacle avoidance and distance measurement systems. The ultrasonic range finder measures the distance by emitting a 40 kHz pulse of ...
It’s a challenge to interface a resistive bridge sensor with an ADC receiving its power from a 5 V single-supply power source. Some applications require output-voltage swings from 0 V to a full-scale voltage, such as 4.096 V, with excellent ...
Simple circuit saves hard-working fingers from unnecessary wear and tear. Digital potentiometers (DPOTs) with manual up/down increment/decrement interfaces can have real utility as versatile substitutes for traditional electromechanical pots. But ...
There are times when you would like to flash a LED through a thick plastic case without wires. The circuit below performs this feat. It can be powered from a supply ranging from 3 V to 6 V. It draws about 300 µA of average current at 5 V. It ...
Disclaimer: Some parts of this circuit carry dangerous Mains voltage. If you are a beginner, seek guidance from experienced users. Dealing with the 110 V/220 V AC mains voltage and measuring the AC load parameters are regarded as a challenge for ...
Some folks prefer pushbutton switches to take effect on push instead of release. These buttons do that very thing. I suppose it’s really just a matter of taste, but I’ve always liked momentary contact switches that act when you push ...
