JLCPCB.COM – EAGLE GERBER EXPORT AND QUICK PCB REVIEW

We recently placed an order on JLCPCB.com for 5 pieces of a PCB design we have done here at electronics-lab.com. The project we were dealing is a 60V to 5V @ 3.5A buck converter based on TPS54360B and we are going to publish it soon under Projects -> Power. The PCB design has 2 layers and was done on Autodesk Eagle. In […]

Radioactivity detection using very simple ionization chamber and a single J FET transistor

Radioactivity detection using very simple ionization chamber and a single J-FET transistor

Today I will show a very simple ionization chamber that can detect radioactivity. I was able to detect with it ionizing radiation from a smoke detector (Am241 isotope). It’s also immune to electromagnetic interference (EMI) due to a good shielding. This device doesn’t explicitly use any power supply. It’s connected to a multimeter set to measure resistance,

THE TOP 10 LINEAR VOLTAGE REGULATORS ACCORDING TO SNAPEDA

THE TOP 10 LINEAR VOLTAGE REGULATORS ACCORDING TO SNAPEDA

In electronics, linear voltage regulators are commonly used to stabilize voltages. Regardless of the input voltages or load conditions, they will provide fixed output voltages, thus protecting devices from fluctuating outputs, which can cause inefficient performance or even damage. When designing a power supply for an application that requires a small difference between its input
