Introduction Power supplies are everywhere these days. With the advent of switching power supplies, the cost of high-current supplies has radically dropped. Maybe you’ve noticed how the large, heavy, wall-wart style adapters are no longer lurking around your baseboards, falling out of their sockets? Or occupying several of your valuable power-strip positions? But not all

Introducing the Mobilinkd Bluetooth APRS® TNC. With your radio, your Android phone and this TNC, you have everything you need to get started with APRS — all at a fraction of the cost of a dedicated APRS® radio, and with a better user interface than any APRS® HT on the market. Why a Mobilinkd TNC?
USB Power supply Active Load Tester or short PAL Tester is unit designed for testing the quality of the power supplies. Idea was to create low-cost, precise device for simultaneous measurement of Voltage and Current drawn from the device under test. This is one of my weekend projects that I have decided to release to
PORTLAND, Ore.—Today Yole Development predicted that power transistors would radically shift from silicon wafers to silicon carbide (SiC) and gallium nitride (GaN) substrates—to achieve higher power in smaller spaces, according to its GaN and SiC Devices for Power Electronics Applications report. One of the big drivers behind the shift is the electric vehicle (EV) and
DISCLAIMER: This is an extremely dangerous project, and it should only be attempted by people with experience in electronics, and specifically, High Voltage. If it’s your first time seek help for your own safety. Homemade High Voltage supplies are unlikely to meet any international standards, the safety and correct operation is NOT guaranteed at all,
Cypress Semiconductor has introduced what it believes to be the lowest-available-power PMICs that enable an integrated module size of 1 cm² for solar-powered wireless sensor node (WSN) designs. Intended to manage solar-powered wireless sensors for Internet of Things (IoT) applications, these parts are said to be the lowest-power, single-chip Energy Harvesting PMICs, and can be

General considerations: There are several types of dimmers generally available. These are used for resistive, and inductive loads, such as incandescent,cold cathode and low voltage (inductive) lamp sources. Note that not all electronic transformers used for low voltage lamps are suitable for dimming by Triac or Thyristors dimmers. In case of Thyristors you need

The latest buzz in the information technology industry regards “the Internet of things”—the idea that vehicles, appliances, civil-engineering structures, manufacturing equipment, and even livestock would have their own embedded sensors that report information directly to networked servers, aiding with maintenance and the coordination of tasks. Realizing that vision, however, will require extremely low-power sensors that
Universal connectors for interconnection of leads (wire-to-wire) as well as leads to a PCB (wire-to-board) are necessary every day and practically everywhere. In industrial applications we usually need various connectors. “Various” usually means almost uncountable amount of types, that´s why it´s usually a big advantage if it´s possible the same connector for several applications. This
