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 -...

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...

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...

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...

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...

Happy New Year 2016 to all of you. May the new year bring you happiness and...

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...

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...
