Super Capacitors have become more popular over the past 5 years and are beginning to replace batteries in some applications. Charging a super cap can be tricky especially if you want to avoid damaging it. Here is a basic circuit that will allow you to charge a super capacitor with a solar panel. For […]

Push-buttons resistant to dust and water, moreover with the well-visible LED backlight, will manage even rough handling. If you have an application, where you need sturdy push-buttons and ideally even with backlight, then the Schurter MSM19 may be the right for you. Dust- and water-proof push-buttons can be advantageous not only in an expressly demanding

Voltage conversion from 24VAC to 5VDC is quite useful, because a lot of home automation devices use 24VAC, including sprinkler solenoids, home surveillance systems etc. Having a conversion module makes it easy to use a single power supply, without a separate 5V adapter for your control circuit. There are plenty of resources you can find
