JellyScope: Open Source Android Oscilloscope
This circuit consists of two parts: the analog frontend, which prepares the input signals for the A/D converter, and the digital pre-processing stage, which quantifies the data and organizes it for transport via the USB interface. Key components include a Xilinx Coolrunner CPLD and a Cypress FX2 microcontroller. The display can be viewed on an Android tablet or smartphone.
HDMI to VGA: USB-Powered DVI/HDMI-to-VGA Converter with Audio Extraction
HDMI converters are abundant, but those with separate audio paths are rare. This article presents a complete solution for converting HDMI/DVI to VGA with an analog audio output. It includes an HDMI receiver capable of processing video streams up to 165 MHz. The converter supports resolutions up to 1,600 × 1,200 pixels at 60 Hz.
WEB-ArBYTER: Control Embedded Projects via Smartphone
Microcontroller projects are no longer isolated systems. Once you've enabled your microcontroller projects to communicate with the outside world via Ethernet, you won't want to go back. This opens up an almost endless variety of new possibilities. With an ARM-based microcontroller module, connecting your own projects via Ethernet or WLAN is straightforward. This article guides you from creating your own web service to implementing smartphone app-style control.
USB 2.0 and 3.0 Port Monitor with MSP430
This monitoring circuit with a microcontroller enables current and voltage monitoring on USB ports according to USB 2.0 and 3.0 standards. To achieve the intended measurement accuracy, certain tricks are necessary.
Nimm Zwei: Dual USB Power Supply
A dual USB connection? Simply add a second socket in parallel. This is one of those practical solutions that often works but is not always reliable. This article shows how it should be done to ensure it always functions correctly.
Install Linaro Android on the PandaBoard
A step-by-step guide to setting up a Linux build environment, compiling Android sources (Linaro Android Build, 4.1.1 Jelly Bean), and starting development on an Ubuntu 12.04 (64-bit) computer. The target platform is a PandaBoard, and the installation is performed on an SD card.
Develop Qi-Compliant Wireless Charging Station
Wireless power supplies are an attractive method for charging batteries in all types of mobile devices. Wireless Power Transmitters (TX) according to the Qi standard are the central elements of this new technology. This article supports developers in building these energy transfer systems. In addition to a step-by-step guide, it covers what is permitted and what is not.
Prêt-à-porter: Market Overview of Embedded CPU Modules
Off-the-shelf embedded systems account for half the market. The other half is custom-designed. However, 'off-the-shelf' can indeed be worth considering. So-called Computer-on-Modules can be relatively small, typically have a full complement of I/O, and often run Windows or Linux, which can simplify software development.
The Better Flash Memory: FRAM - Function, Quality, and Reliability
FRAM: the unknown memory? Yet, this technology has the potential to be a real insider tip, as it combines the fast access and low power consumption of volatile RAM with the ability to retain data without power. It offers the speed of RAM and the non-volatility of Flash.
Transit-Chip LPC-800: 32-Bit ARM in 8-Bit Guise
With the LPC-800 family, NXP is making a new attempt to draw users of 8-bit microcontrollers into the 16/32-bit realm. The transition is described as "revolutionarily simple."
Don't touch: E-Field-Based Gesture Control
Operation without haptic feedback: Microchip aims to make this possible with its contactless, gesture-based operating interface, GestIC. The technology is based on a configurable 3D gesture controller that evaluates E-fields.
