Fluke/Philips PM66xx Frequency Counter OCXO Upgrade
https://www.electronics-lab.com/flukephilips-pm66xx-frequency-counter-ocxo-upgrade/
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 550MHz. The design feels dated compared […]
Arduino IR remote and Software controller
https://www.electronics-lab.com/arduino-ir-remote-software-controller/
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 have sets of speakers and […]

Rechargeable batteries with nanowires last forever
https://www.electronics-lab.com/rechargeable-batteries-nanowires-last-forever/
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 eliminate the need to replace a battery made from this material during the lifetime of the […]
LTC4380 – Low Quiescent Current Surge Stopper
https://www.electronics-lab.com/48785-2/
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, capacitors, transient voltage suppressors (TVS), and fuses with a simple IC and series N-channel MOSFET solution, saving […]
USB to UART Converter with GPIO – MCP220
https://www.electronics-lab.com/usb-uart-converter-gpio-mcp220/
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 EEPROM. The MCP2200 has eight general purpose input / output pins. Four […]
3.3V to 30V DC/DC converter using SN6505A
https://www.electronics-lab.com/3v330v-dcdc-converter-using-sn6505a/
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 […]
DIY 32ch FPV 5.8ghz LCD
https://www.electronics-lab.com/diy-32ch-fpv-5-8ghz-lcd/
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, so I made my own DIY […]
Simple crystal tester
https://www.electronics-lab.com/simple-crystal-tester-3/
Dilshan Jayakody build a simple crystal tester based on Colpitts oscillator. He writes: This is simple Colpitts oscillator to test commonly available passive crystals which range between 2MHz to 27MHz. This unit must connect to an oscilloscope and/or frequency counter to get the frequency of the crystal. This circuit is design to work around 9V […]
