A well known power supply circuit is the capacitance multiplier. It doesn't regulate, but instead reduces ripple & noise while the output tracks at some fraction of the input voltage. The R1/R2 voltage divider determines VOUT (a VBE below VB), and must be chosen to account for the maximum ripple on the minimum VIN. If VIN is regulated, the circuit can be used purely for low-level noise reduction. In thi ...

AIM To control a relay switch using esp8266 in standalone mode(without arduino,pic or any other Micro-controller) via Web-UI The ESP broadcasts its own SSID.It does not connect to a router.local IP address of esp is 192.168.4.1 Step 1: Gather Hardware ESP 8266 (There are a lot of variants available in the market.for this tutorial lets just use the esp-01).If you are curious about the different variants clic ...

DC Output Solid State Relay 10Amps 60V DC (Optically Isolated Input) This project has been designed around TLP250/352 which is Opto-Coupler IGBT/MOSFET Gate Driver from Toshiba and Mosfet IRFP260 from IR, This relay consists of optically isolated gate driver and low impedance Mosfet. The combination of low resistance and high load current handling capabilities make this Relay suitable for a variety of switc ...

Among my recent electronics purchase spree was the amazing Teensy LC from PJRC. It has a nice ARM Cortex-M0+ processor, real hardware USB, and what’s the nicest part, an Arduino add-on called Teensyduino which enables easy programming with Arduino, but with support for many of the hardware features. Now I started playing piano a while ago, and just a few weeks ago bought a Pianoteq license to send notes via ...

It’s been a while since I posted a new article, a delay at least partly due to me herniating a disc in my neck which left me completely unable to look downwards for any length of time and as you’ll know all too well you can’t work on circuit boards without peering down at them. Look after your neck and back folks, and I mean that seriously. Well I’m back now and I’ve got a lot of ideas for articles spinning ...

Up until now, we have talked about working with a lot of low-power devices. Sensors, LEDs, ICs, and the like are all capable of being powered directly from your Arduino, but as many awesome 5 and 3.3v components as there are, eventually you will find yourself holding a 12v solenoid, motor, or light and wondering “How the heck am I supposed to control this from my Arduino?” Well today we are going to talk ab ...

The GS66540C (the picture is of a prior, lower-current part) high current power devices will be revealed for the first time. Part of the company’s family of 650V gallium nitride power transistors based on its proprietary Island Technology, these high density devices achieve extremely efficient power conversion with fast switching rates of >100V/nsec and ultra-low thermal losses. The GS66540C is supplied ...

PORTLAND, Ore.--Purdue University researchers have demonstrated a CMOS-compatible all-optical transistor capable of 4THz speeds, potentially over a 1000 times faster than silicon transistors. Nano-photonic transistors processed at low-temperatures can be fabricated atop complementary metal oxide semiconductors (CMOS) to boost switching time by ~5,000-times less than 300 femtoseconds (fs) or almost 4 teraher ...

PORTLAND, Ore. -- A new type of transistor harnesses a new effect--called the quantum spin Hall effect -- to create a topological field effect transistor (TFET) according to a Massachusetts Institute of Technology (MIT) researcher who recently moved to the newly formed Department of Materials Science and Engineering at Texas A&M University where the Texas Advanced Computer Center (TACC) confirmed the re ...

I've been browsing this forum and the internet now for a couple of days and what I thought would be an easy side project turned into a (for me) quite complicated matter. I'm planning to build a mood light that consists of 12 common cathode rgb LEDs with each colour being controlled by an Arduino's PWM pins. In this diagram that has been posted here a while ago I found pretty much the outline for all that I ...
