Simple products are often less exciting than complex, high-tech ones, but provide an opportunity to learn about smart and efficient design. Robotwist is an example of a product that understands ...

Using simple components such as oil, salt water, lipids and proteins, plus routine genetic engineering techniques, it is possible to create simple nanofluidic circuits.

Circuit design A simple DNA strand displacement motif called the seesaw gate was developed to scale up the complexity of DNA circuits 22 and was used to demonstrate digital logic computation 12 ...

When I was recently debugging a design, I discovered that a short circuit existed from a ground plane to a power plane. I did not have access to a milliohmmeter or an equivalent tester for locating ...

Acquire practical skills of coding hardware description language Verilog/VHDL for modern digital design. Know how to use modern EDA design tools to perform simple logic circuit design. Perform simple ...

Most circuits that require current loss detection use expensive isolation amplifiers. This circuit solves that problem with a simple and low-cost method to detect current loss of 4-20 mA.

Moving air provides a better conductive path and cooling method for hot components than stagnant air. Therefore, airflow is a critical parameter in systems where heat build-up ...

The Design Idea in Figure 1 indicates a low-battery condition in an audio test instrument that is powered by four AA cells. As the instrument was otherwise an all-discrete design, this same approach ...

Consider this simple common emitter amplifier (I modeled it in PartSim, if you’d like to open it): In this particular case, there are several key design parameters.

When reaching for a power supply design it’s normal here in 2022 to reach for a switching design. They’re lightweight, very efficient, and often available off-the-shelf at reasonable pr… ...

A Simple Over-Voltage Protection Circuit for LED Drivers This boost circuit implements current mode control and senses the LED current via resistor R14. The output voltage is boosted to just over 30V ...
