Sensor circuits that connect to thermocouples ... I built and bench-tested this circuit using an InterFET IF170. I hand-wound the inductor on a ferrite core that I salvaged from a Bourns 1120-1ROM-RC ...

Have you ever noticed how shopping malls, parking lots, or event venues seem to track the number of people or cars… ...

Have you ever wanted to build your own IoT-based Weather Monitoring Station? Imagine monitoring real-time temperature, humidity levels,… ...

The circuit he’s building here is a solar charger ... and they aren’t limited to small applications either. For example, this RC plane was converted to run with super capacitors.

In this paper, an analog-based phase calculation readout circuit with a 3 μs row time for an indirect time-of-flight (i-ToF) 3D image sensor is proposed. The circuit achieves the calculation of ...
