In this post Dan Watson documents an OCXO upgrade board he designed for the Fluke/Philips PM66xx line of frequency counters. A few months ago I purchased a Philips PM6674 frequency counter on eBay. It's an older 9 digit counter with two channels that has a maximum input frequency of...

This is a DIY Infrared remote for speakers, replacing the original. Arduino Nano and controlled via a custom .NET application and placed in a laser cut enclosure. This one is an interesting one, it’s something we’ve been looking at for a while and figuring out how to solve it. We...

geekrex @ instructables.com shows us how to use ESP8266 Wifi module for home automation. He writes: ESP8266 is a great thing for starting to Wifi And IOT. It is also cheap and be used for making cool projects connected to the Internet .Learn how to make a simple IOT Project with it...

by Harry Baggen @ elektormagazine.com: Researchers at the University of California (USA) have developed a nanowire-based material that allow a rechargeable battery to be charged and discharged hundreds of thousands of times without any loss of capacity. This would virtually...

The LTC4380 is an ultralow quiescent current (IQ) surge stopper, providing compact overvoltage and overcurrent protection for always-on 4V to 72V electronics in automotive, industrial and avionic systems. The LTC4380 replaces traditional shunt circuits composed of bulky inductors,...

The Module is based on The MCP2200, which is a USB-to-UART serial converter which enables USB connectivity in application that have a UART interface. The device reduces external components by integrating the USB termination resistors. The MCP2200 also has 256-bytes of integrated user...

Bob tipped us with his latest project. It's a 3V3/30V DC/DC converter using SN6505A from TI. Recently I'v got my samples of SN6505A, it's a really nice IC, so I decided to make a simple DC/DC converter to get familiar with it. What I like in this chip is that it can operate on input...

Spikey made his own DIY 32ch FPV 5.8ghz LCD. He writes: If you’re like me, you don like buying stuff that’s ready-to-go, but rather build one yourself. We usually spend more money, but it’s way more satisfying I really didn’t want to buy an overly expensive FPV LCD receiver,...
