Free Fresh Article: Capaci-Meter

With the compliments of the Elektor Labs and Editorial teams, here comes another fresh-out-of-the-lab article that's free to download by all registered Elektor e-zine readers. "Free Fresh Articles" are published at two-weekly intervals in the Elektor e-zine, alternating with "Free Back Articles". This time we have a DIY capacitance meter that’s remarkable for its accuracy, low cost and beautiful PCB design. It has a two-digit Dekatron-style display made from discrete LEDs, and zero (0) microcontrollers inside, yet achieves 5% accuracy across its range of 200 pF to 9.9 uF.

This is a submission from Keysight Technologies, Inc. on new 5G channel emulation capabilities that enable the deployment of seamless connectivity and end-user experiences.

Want to introduce your electronics-related startup to the global market! Would you like a chance to bring your young company to the attention of potential customers and investors? electronica fast forward, the start-up platform powered by Elektor, offers you a unique opportunity to present your startup and technology to the world.

This is a submission from Rutronik on Infineon‘s NFC-PWM (Pulse Width Modulation) series consisting of NLM0011 and NLM0010. It provides fast and cost-effective implementation of Near Field Communication (NFC) programming for LED drivers. Contactless exchange via NFC replaces the labor-intensive plug-in resistor current setting method, thus improving operational efficiency and maximizing flexibility in the value chain.

It’s well known that electronics engineers never have enough power supplies. I’m no exception to this rule, as you can see from a photo of the home lab in my basement. The neat PeakTech 6080 A power supply is unusual amongst all the PSUs on the market today. It has been designed using linear technology with a traditional power transformer. The result is a quiet output voltage, highly accurate displays and all for not much money at all...

This is a submission from Microchip Technology Inc. They announced TÜV SÜD certification of its MPLAB® XC compilers for functional safety, significantly simplifying the functional safety qualification process for Microchip’s PIC®, AVR® and SAM microcontrollers (MCUs) and dsPIC® Digital Signal Controllers (DSCs).

In the previous instalment we looked at the simplest possible radio receiver: the diode receiver. And in order to tickle a little bit more sound volume out of it, we added a small amplifier stage. Nevertheless, such a diode receiver has its disadvantages. Here we will try to do something about that.

This is a submission from Power Integrations on the launch of its automotive-qualified SID1181KQ SCALE-iDriver™ gate driver for 750 V-rated IGBTs. The new part expands the company’s range of auto-qualified driver ICs, following the introduction of the 1200 V SID1182KQ driver IC.

STMicroelectronics has made available a software expansion package (I-CUBE-LRWAN) for developers working with LoRaWAN® STM32L4 microcontroller-based systems to implement the latest FUOTA specification...
