How To Select an Inductor
https://www.electronics-lab.com/how-to-select-an-inductor/
Sanket Gupta pointed us to his latest article, on how to select an inductor and discuss about the various types of them. Inductors are two-terminal components used for filtering, timing and power electronics applications. They store energy in the form of magnetic fields as long as a current is flowing. Inductors oppose a change in […]
ArduCAM Introduces tiny Raspberry Pi compatible board
https://www.electronics-lab.com/arducam-introduces-tiny-raspberry-pi-compatible-board/
ArduCAM has introduced a tiny Raspberry Pi compatible module based on Broadcom’s BCM2835 Processor, the same chip found in the original Raspberry Pis A, B, B+ and Zero. This module is tiny, measuring only 24 x 24mm and it is compatible with all of the software that makes the Raspberry Pi so popular. It comes with 256MB/512MB […]
VXO – based PLL frequency synthesizer for 7 MHz
https://www.electronics-lab.com/vxo-based-pll-frequency-synthesizer-7-mhz/
Vasily Ivanenko made a VXO-based synthesizer: To make a VXO to mix with a ~7 MHz VCO, you’ll need a crystal that is higher in frequency than the highest frequency you want to synthesize. Some rummaging revealed a bag of 21.4773 MHz crystals that I could divide by 3 to garner 7.159 MHz. To afford a […]
The future of IC design
https://www.electronics-lab.com/future-ic-design/
R Colin Johnson @ edn.com discuss about the future of IC design and the different technologies that can extend Moore Law. Such technologies include 3D memories, superconducting, quantum, neuromorphic and photonic mixed-signal devices. To celebrate 60 years of EDN, we’re looking into the future to predict what advancements will be made in IC Design in […]
Memory upgrade for ESP8266
https://www.electronics-lab.com/memory-add-esp8266/
Pete show us how to upgrade your ESP8266 with 32Mbit memory chip. Some time ago I passed comment in here about converting an ESP-01 to 32Mb (or 4MB). And here it is in the flesh – a 32Mb ESP-01 – and also – at last – Sonoff Upgrades. Now, why would you want to do […]
Build an Arduino boost converter
https://www.electronics-lab.com/build-battery-boost-power-supply/
Lucas Reed has a tutorial on how to build a boost converter using an Arduino. Have you ever needed to power a project that’s not near an outlet? Have you needed to test using different voltages? Are you curious about analog circuits and power? Using Autodesk Circuits and a lead-acid battery, you can create a […]
HC-12 433MHz wireless serial communication module configuration
https://www.electronics-lab.com/hc-12-433mhz-wireless-serial-communication-module-configuration/
Dziku show us how to configure HC-12 wireless module using AT commands. HC-12 are cheap 433MHz wireless serial port communication modules with a range up to 1800m in open space. Each costs about $5 when bought from China, and 2 of them can create wireless UART link that can be used, for example, to transfer […]
Optogenetic hardware setup
https://www.electronics-lab.com/optogenetic-hardware-setup/
How electronics and neural systems can work together, amazing! Arthur English’s group at Emory has developed a custom device that they have used for stimulating peripheral nerves optically in anesthetized mice using a standard optical fiber. The device is compact, rechargeable battery-operated, and controlled either manually or by computer using an analog input. Optogenetic hardware […]
Arduino UNO Components library
https://www.electronics-lab.com/arduino-uno-components-library/
pighixxx.com has published Arduino UNO components in vector format. As promised, I publish the first components library to make pinouts. In particular it’s a library dedicated to Arduino Uno Boards, clones and related projects. The file contains several vector formats and any component can be expanded (For example the Atmega328 with and without socket) Arduino […]
PCB Business Card
https://www.electronics-lab.com/pcb-business-card-2/
alex.puffer @ hackaday.io designed a nice PCB business card with onboard 555 timer IC. I decided I was tired of paper business cards, and wanted something more fun (and more impressive to show off). Having a PCB business card is also a perfect portable portfolio, showcasing my design and layout skills. This project will span […]
