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 […]
Raspberry Pi Zero Extreme Teardown
https://www.electronics-lab.com/raspberry-pi-zero-extreme-teardown/
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. […]

Happy New Year 2016 to all of you. May the new year bring you happiness and prosperity.
UCload new PCB build
https://www.electronics-lab.com/ucload-new-pcb-build/
Sjaak has published a new PCB build, uC controlled dummy load: With no snow outside I finally got around to solder the 3rd PCB. It is the second revision of a microcontroller dummy load. It is loosely based on the arachnidlabs uc:load. It uses the same base ciruit and adds a microcontroller (PIC16F1825), rotary encode […]
Adding a USB power port to a switch for IoT
https://www.electronics-lab.com/adding-a-usb-power-port-to-a-switch-for-iot/
Jesus Echavarria @ jechavarria.com has tipped us with his latest project. In this project he adds a USB power port to a switch. Also I need a power supply for the Arduino board, and I think that, better than a external USB AC wall adaptor or power supply, is modify the switch to add it a […]
Converting from Eagle to KiCad
https://www.electronics-lab.com/converting-from-eagle-to-kicad/
lachlanA @ github.com has published a Eagle SCH/LIB to KiCad SCH/LIB ULP conversion script: The following 5 ulp (eagle user script file) and one ulp include file, work together or stand alone to convert Eagle sch/pcb version 6.xx(7.xx maybe?) file(s) and any version of Eagle lib(lbr) to KiCad sch/pcb and lib/mod files. Converting from Eagle to KiCad […]
