Hand soldering Surface Mount Devices (SMD) scares a lot of DIYers and Makers, but it is easier than what it looks like. Even sometimes, it’s easier than soldering Through Hole Components. Really! Continue reading How to Hand Solder SMD→
If you want to power up your Mini Dual Power Supply, you need to supply it with an AC voltage on its input.
You can either use a simple tranformer or, safer and easier to manage, use a AC/AC wallwart adapter.
It’s not easy sometimes to make distinction between an AC to DC adapter and an AC to AC adapter. They share the same form factor, the same look and feel. But there are clear indications to help you determine the type of each one.
Here’s a quick comparison between the two types with two example closeup pictures, one AC/DC adpater and one AC/AC adapter: Continue reading Choosing a suitable adapter for the MDPS→
Connecting your module for the first time can be tricky. There are chances to destroy it.
Ok, what to do then? Well, you need to check the following points before pluging in anything, and most important : Never trust the red stripe.
Basics of Ferrite Beads for Filters, EMI Suppression, Parasitic oscillation suppression / Tutorial
This video discusses the basics of ferrite beads, and their uses for basic filtering applications. It discusses and demonstrates how ferrites act as resistors at high frequencies, and how this is used for EMI/RFI Suppression, improved power supply filtering, parasitic oscillation suppression, and others. The affect of the frequency dependent resistive characteristic of the ferrite beads is demonstrated by showing its effect on a swept RF signal, its effect on the rise/fall time of a digital signal, and its effectiveness of eliminating parasitic oscillation.
