First, you need to know that a lightstrip is a bunch of LEDs daisychained together. The three contacts are +5v, GND and DI (data in, AKA DIN). If you are using the same lightstrip, you can solder just 3 wires… Now on to building Step 1: Tinning Your Contacts Before soldering anything, you need to […]

Ricoh Electronic Devices launched RP516 and RP517 series, buck (step-down) DC/DC converters featuring ultra-low output voltage (0.3 V to 1.2 V) and ultra-low quiescent current (typically 0.3 ”A). The new converters are designed for IoT systems. As the IoT market expands, IoT devices with sensors, MCUs, communication ICs, etc. are required to correspond to low voltage to prolong the operating time of the

Introduction Driven by the need for untethered mobility and ease of use, many systems rely on rechargable bat- teries as their primary power source. The battery charging circuitry for th ese systems is typically implemented using a fixed- function IC to control the charging current/voltage profile. The C8051F30x family provides a flexible alterna- tive to

Researchers at the University of Houston reported in the journal Nature Communications the discovery of a new design that significantly improves the development of a battery based on magnesium. Magnesium batteries are considered as safe resources of power supply â unlike traditional lithium-ion batteries. They are not flammable or subject to exploding â but their ability to store energy is
Rechargeable Magnesium Batteries â Safer And Cheaper Than Li-ion Batteries Read More »
Lithium-sulfur batteries are suitable for both vehicle and grid applications as they are ultra-cheap, high-energy devices. Sulfur is a very low-cost material and the energy capacity is much higher than that of lithium-ion. So, lithium-sulfur is one chemistry that can possibly meet the demand for energy storage at a cheap price. However, the serious problem is, lithium-sulfur
