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.

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.

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.

I finally finished the next version of my TinyLoadr AVR programming Shield – and it’s not a shield. It’s a standalone USB programmer, so you no longer have to have an extra Arduino laying around. The best part? It’s the same price as the shield was!

Banguino brings the most popular hobby and DIY development platform in the world into a single chip DTX module and offers full backwards compatibility with the most used worldwide Arduino board – the model ‘Uno’.
Bonus features include an on-board power supply to generate +5V and +3.3V to the user’s external circuit, a microSD connector and additional 10 configurable digital I/O ports. There are also two software controllable LEDs on board as well as a USB-to-UART bridge. Banguino provides a highly integrated solution for building simple or complex circuits and benefiting from the large variety of already existing Arduino-compatible code.

Espruino Pico has everything you need pre-installed. It can be used from virtually any device with a USB port so you can get started in seconds.
Today, we’ll be discussing Rigol’s MSO2302A Mixed Signal Oscilloscope from the MSO2000A series. Starting at $1,239, this oscilloscope features 300 MHz bandwidth, with 2 giga-samples per second, a memory depth of 14 megapoints (Mpts), with an option up to 56 megapoints. The large 8 inch high resolution screen typical to Rigol scopes allows for easy review of your data. 2 channel input and has an ethernet connection for networking and USB ports to interface with computers, save waveforms to USB storage devices, or print directly to printers.

Ever wanted to visualize your brain activity in real-time? Move an object on a screen with your mind? EEG devices are fantastic fun and allow you to do such things!
This tutorial will show you how to make an illumino: an easy-to-use recreational EEG device hidden inside a comfortable beanie, that turns your brain activity into an array of colorful light. Colors and brightness are manually selectable and adjustable via a small discreet pushbutton switch. The custom Arduino software is accessible via a USB port, allowing you to easily change it as you wish. The hat also works fine without the lights, should you wish to use it only as an EEG device. I recommend using Processing to create beautiful real-time moving graphical visualizations of your brain activity (code included in tutorial).
