Lead Acid Battery float charger
https://www.electronics-lab.com/battery-float-charger/
Nobilis @ instructables.com has build a lead acid float charger out of an old phone wall charger: If you do not use your motorbike on the winter or your car stands for weeks — you better have a float charger connected to the battery. Otherwise you probably encounter engine starting problems, and your battery’s lifetime […]

https://www.electronics-lab.com/maxim-reference-design-wearable-galvanic-skin-response-system/
The MAXREFDES73# reference design from Maxim Integrated is a wearable, mobile galvanic skin response (GSR) system featuring the MAX32600 wellness measurement microcontroller. his battery-powered platform takes high-precision AC impedance measurements while consuming minimal power. The MAX32600 microcontroller features the industry-standard ARM® Cortex®-M3 32-bit RISC CPU that operates at up to 24MHz, while integrating multiple high-performance […]
Better 3D graphics on the Arduino – ILI9341 LCD
https://www.electronics-lab.com/better-3d-graphics-on-the-arduino-ili9341-lcd/
M Rule @ crawlingrobotfortress.blogspot.com discuss about ways to optimize 3D rendering on ILI9341 LCD and Arduino: Both optimizing ILI9341 LCD drivers and rendering basic wireframe meshes have been done before. XarkLabs provides an optimized fork of Adafruit’s library. Youtube user electrodacus has also implementd an optimize driver for the ILI9341 communicating over SPI. Better 3D graphics on […]

A very close look at the new Raspberry Pi, include a die-dcap of the SOC (system on chip) and looking at what some of the silkscreen text means Raspberry Pi Zero Extreme Teardown – [Link]
Building a piCentr home media center
https://www.electronics-lab.com/building-a-picentr-home-media-center/
mjrice @ instructables.com shows us how to build a Raspberry Pi home media center. The layout of the enclosure is meant to keep all cabling tidy and inside out of view, with accessible ports for everything you need. A 3D printed internal chassis is part of the design, which holds the Pi 2 and up […]
Isolated USB-to-UART converter
https://www.electronics-lab.com/isolated-usb-to-uart-converter/
Jacob Beningo shows how to build an isolated USB to UART converter using Sparkfun’s modules. A simple isolation circuit that costs only a few dollars could have been used to protect the USB port on the computer. Embedded system developers get used to plugging strange hardware and components into their computers on a daily basis […]
Inside the ALU of the first ARM microprocessor
https://www.electronics-lab.com/inside-the-alu-of-the-first-arm-microprocessor/
Dave @ daveshacks.blogspot.co.uk takes a look inside the first ARM microprocessor and explains it’s design. With that in mind I embarked on my own attempt to reverse-engineer parts of the armv1. Some background knowledge of the processor’s architecture is helpful, and googling for “ARM Architecture Reference Manual” will lead you to very detailed descriptions of […]
INA219 current sensor DIY Breakout board
https://www.electronics-lab.com/ina219-current-sensor-diy-breakout-board/
Juan Ignacio has designed a INA219 current sensor DIY Breakout board: Another small board, this time for a INA219. The INA219 is a high-side current shunt and power monitor with an I2C interface. For testing I used Rei VILO library with a MSP430G2553 and Energia, and I measured the power consumption for this simple circuit. […]
