A defective parking sensor can be expensive. Here is a small circuit that you can use to quickly and easily detect defective ...

This circuit prevents us from making power supply errors, using a different cable for each single output voltage. Let’s see how the PSU works.

The environment in a rainwater tank is very hostile to electronics. Sooner or later, the high humidity destroys e,g, the plug connections. Here my newest solution to avoid this, using better material, ...

This Pre-Amplifier circuit is a minimalistic design, a.o. inspired by valve design, which should help sound clarity. The circuit counts 5 transistors, has 0.1% distortion (expected from 60dB loop gain ...

Explore how the integration of a standard ultrasonic sensor, a vibration motor, and one or two microcontrollers resulted in a functional enhancement for a mobility aid. The developed ultrasonic ...

In the professional analog audio field not only the inputs and outs are differentiel. Also some internal processing like driving an ADC and receiving the signals of DACs. I develloped four small PCBs ...
