Accelerating data rates, greater design complexity, standards requirements, and shorter cycle times put greater demand on design engineers to debug complex signal integrity issues as early as possible. Because today’s serial data links operate at gigahertz transmission frequencies, a host of variables can affect the integrity of signals, including transmission-line effects, impedance mismatches, signal routing, […]

10-minute sewable iPod remote There are a lot of really cool iPod remote control projects: some have simple buttons, some react to  heartbeat or body motion, and others are designed to interface directly with software running on a computer. However, not one of them is truly wearable, or speaks to the unique needs of e-textiles designers.  […]

The PIC32 single-board computer is a de facto standard tool for developing microcomputer applications within the hobbyist and educational communities. It provides an open-source hardware (OSH) environment based on a simple microcontroller board, as well as an open-source (OS) development environment for writing software for the board. Here’s an approach that enables PIC32 code to […]

A BIG HELLO! and welcome to Mixed Outputs first instructable. As most of my project involve electronics of some sort, having a good power supply is essential to be able to meet the demand of different power requirements. So I built me a bench-top power supply from an old ATX power supply Unit (PSU) that […]

MediaTek expects to see the first smartphone with a mobile processor it has designed based on an ARM Cortex-A72 dual core processor before the end of the year. MediaTek of Taiwan is believed to be the first chip firm to see first silicon of the new 64-bit processor, which will give mobiles PC-class performance for […]

Introduction HD44780 based character LCDs require at least 6 I/O lines from microcontroller to display data. Therefore, they are not suitable for low-pin microcontrollers like PIC12F series microchips. In this project, I am going to show how to drive an HD44780 based LCD display with only 3 pins of a microcontroller. I am going to […]

Amazon’s Dash Button, which I previously mentioned back in late May 2015, is the ultimate in consumer convenience (or, if you prefer, consumerism gone crazy). Simply press a button on the inconspicuous adhesive-backed device (perfect for attaching to your washer and dryer, refrigerator, counter, or cabinet), and your Amazon account is charged for the purchase […]
