Control of up to 680 pixels on any of the popular LED strips from any device with a USB port! One controller to rule them all!

Working with addressable LED strips, we’ve found that the extra components required to communicate with and power them complicate designs and limit the options for how they can be used. Each chipset requires its own special protocol and supporting hardware components. This is where the AllPixel comes in. Think of it as a video card for your LED strips.

FTDIusb3.0

by elektor.com:

The FT600 and FT601 are both USB 3.0 to FIFO interface chips supporting the USB 3.0 Super Speed (5 Gb/s) and USB 2.0 High Speed (480 Mb/s) data transfer standards. The FT600Q has a 16-bit wide FIFO bus interface and comes in a 56-pin QFN package while the FT601Q uses a 32-bit wide FIFO interface, packaged in a 76-pin QFN outline. The FT601 and FT600 support both the single-in and single-out 245 FIFO interfacing standard and the multi-channel FIFO mode which can handle a total of 8 channels (4 INs and 4 OUTs). The FIFO interface can support multi-voltage I/O (1.8 V, 2.5 V or 3.3 V) and an operating frequency of 66.67 MHz or 100 MHz (100 MHz only for 2.5 V and 3.3 V).

High power of the UDOO “asks” for usage. One of many occasions to make it is to use various available periphery thus gaining a truly universal platform.

Favorite powerful embedded SBC called UDOO (S975-G000-2100-C2) already found many fans. Maybe also because of its compatibility with the Arduino Due platform (hardware and software) and mainly, it´s possible to connect it with various accessories. Thanks to a wide range of interfaces (USB, Ethernet, bluetooth, WiFi, …) is a connection of periphery flawless, what´s also a case of the 5MPx camera (autofocus).

Despite miniature dimensions this camera provides very decent resolution and speed – for example VGA (640×480) @90fps or 1080p @30fps, or QSXGA (2592×1944) @15fps. Also beneficial is recording of a video in a full 70°field of view (FOV).For a practical usage and application development with UDOO also serves the „Starter kit EU” containing an adapter for the third USB, RTC battery holder, HDMI cable with the UDOO logo, USB/ Micro USB Type B cable, SATA power supply cable, power supply adapter and an 8 GB micro SD card.

Perhaps the biggest “attraction” is the spacious 7“ display KIT LCD 7”–Touch 800×480 px RGB with a capacitive touch panel. By connecting of this display with the UDOO microcomputer, we get a ready-made platform usable to control various processes, with a power, which easily suits to majority of applications. Detailed information about the UDOO can be found in our article: Do you want a microcomputer which will „handle everything“?.

rftoy_annotated-1024x543

RaysHobby build a project called RFToy:

it’s an Arduino-compatible microcontroller board for interfacing with radio frequency (RF) modules, such as the popular 433/315MHz transmitter/receiver, and the nRF24L01 transceiver. The RFToy has a built-in ATmega328, USB-serial converter (CH340G), 128×64 OLED display, three buttons, and a coin battery holder. Programming is done in Arduino through the on-board mini-USB port. It has three sets of pin headers to directly fit RF modules, and an audio jack to output RF receiver signals to a computer’s sound card. Using RFToy you can build a variety of projects involving RF modules, such as remote control and wireless sensors.

In this world exclusive episode, Shahriar takes a close look at the all new Tektronix Real-Time USB Spectrum Analyzer. The RSA306 has an RF bandwidth from 9kHz to 6.2GHz with a real-time analysis window of 40MHz. While being entirely powered form a single USB 3.0 interface, it provides a 100% Probably of Intercept for any signal event of at least 100us in duration. The RSA306 is compact, lightweight and shock resistant. At the same time Tektronix has made its Signal-Vu PC software with 17 measurement capabilities free and significantly reduced the price of other Signal-Vu advanced applications!
The SFDR, linearity, noise floor and phase noise of the instrument are all measured and presented. The unit is then used to capture and analyze an intermittent RF interference, analyze and demodulate an RF FM signal using an antenna as well as demodulation a 256-QAM signal with -65Bm of total power.

Tektronix-RSA306-652

by elektor.com:

In a break with tradition Textronix have announced their first USB-based item of test equipment. The RSA306 is a spectrum analyzer with a 9 kHz to 6.2 GHz frequency range and a 40 MHz instantaneous bandwidth. According to the press release this is just the first of many test instruments the firm will be launching which takes advantage of the availability of affordable desktop computers and laptops with sufficient processing power to handle complex test and measurement analysis along with high-speed USB 3.0 interfaces.

charger detector figures 3 RGBx600

by Mohamed Ismail @ edn.com:

Other than generous helpings of coffee, what helps industry decrease time to market, drive down cost, and focus more of the design cycle on innovation? Hint: standardization. By defining protocols and operating characteristics, standards have impacted all aspects of technology: device package sizes, pin outs, data and communication interfaces, software drivers, connectors, ESD ratings, environmental compliance, test fixtures. The list goes on and on. The more detailed a specification, the better equipped are developers for defining products that serve the marketplace. If there is any doubt about the value of tightly defined standards, go into any two clothing stores and buy the same size shirt.

Microkite is a DTX module built to utilise the great potential of the new PIC32MX1xx/2xx microcontrollers. It integrates a power supply able to provide power to the external user circuit as well, a microSD connector for data storage and a USB-UART bridge for easy communication with a PC terminal.

The module is intended for inclusion in various control systems and follows the DTX standard pinout which opens the possibility for a trouble-free upgrade with newer models in future. The module fits into a standard PLCC-68 socket and significantly optimises the end user circuit and the later software development process.

Paranoia abounds! well maybe a bit – we are in a situation where we don’t trust our tools – especially our crypto tools – this project is an attempt to create a cheap open source entropy generator that’s open enough that one can verify and trust it.

We’ve based our design on an existing platform – our Cheap RF system – mostly because it’s cheap to build, we had existing hardware, and had just finished bringing up a USB stack for it

Our simple device is a USB stick, it is open source hardware, you can build your own, runs open source firmware – and you can physically open it to make sure that what’s inside is what you expect. With an external programmer you can also program it with your own firmware.

We generate ~350kbits per second of entropy packaged at ~7.8 bits/byte – if you use the entropy data at a lower it accumulates and we quickly approach 8 bits/byte.
