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...

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...

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...

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...

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...

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...
