Pittsford, NY, USA: Saelig Company, Inc. has introduced WiPry-Combo – the worldʼs first dynamic power meter and spectrum analyzer accessory for the iPad, iPod Touch, and iPhone – offering a modern touch interface not available on PC-based instruments. WiPry-Combo turns an iOS device into an ultraportable spectrum analyzer and dynamic power meter. WiPry-Combo brings RF power measurements to a graphical interface to show RF waveforms like an oscilloscope – instead of showing voltage, RF amplitude is displayed on an iOS portable device. Actual power output can be triggered, captured, and recorded for protocol verification or for troubleshooting wireless devices. Data is collected at up to 12 MSa/s, allowing analysis and verification of the smallest protocol level on/off times. WiPry-Combo offers data logging in csv format, while screenshot results can be instantly emailed via the iOS host phone.
In its Spectrum Analyzer mode, WiPry-Combo offers a practical solution for identifying interference or open channels in the 2.4GHz ISM band, or for identifying unauthorized WiFi access points. Operating in the frequency range: 2.400 to 2.495 GHz, it measures signals from -40dBm to +20dBm with an amplitude resolution of 2.0dBm and a bandwidth resolution of 1MHz. The band sweep time is 200ms. Read the rest of this entry »
I needed to charge an iPad, but I couldn’t do it the “normal” way because it was stuck in a wall! I had mounted 2 iPads in walls at a customers house. I did this by cutting a big iPad sized hole in the wall, and then building a custom mounting dock for it. I also embedded an arduino bootloaded ATmega 328 in there along with a MAX3232 (RS232 to TTL) chip for controlling the iPad via RS232. Now all I had to do was keep it charged. I found Ladyada’s mintyboost resources a huge help.

It provides a quick reference manual for the two most popular Hardware Description Languages (HDL): VHDL and Verilog. This app is written by engineers, for engineers. For every construct in VHDL, our app provides the nearest equivalent in Verilog, and vice-versa (or indicates if there is no direct equivalent).
Experienced custom digital logic designer for FPGA or ASIC? Electrical engineering student just learning the ropes? This app (which runs on iPhone and iPad) includes the following features
Searchable dictionary of every keyword, operator, and data type for both languages.
Handbook provides simple example for every single reference
Common functions in each language
All pre-defined attributes for VHDL (e.g., ‘leftof’)
All primitive gates and drive strengths for Verilog
Filter by language (VHDL, Verilog, or both)
Filter by language elements (keywords, operators, attributes, data types, etc.)

For iOS device owners that mess around with electronics, Oscium recently announced the release of the iMSO-104 mixed signal oscilloscope for the iPhone, iPad, and iPod Touch. The hardware, which connects via the dock connector, doesn’t ship until the end of April, but you can download the iMSO app from the App Store now and try it out in demo mode.

While most people would simply throw away an out-of-warranty iPod with a broken play/pause button, Craig gave his a new lease on life by attaching a custom-hacked dock connector. Inside the connector, he stuffed an ATtiny 13 microcontroller with a few other passive components. Now when he pushes the button on the connector, the ATtiny sends the appropriate serial command to the iPod to start or stop the music.

Especially for electronics enthusiasts, students and professionals Elektor now offers an App they cannot affords to miss on their iPhone, iPod Touch or iPad. The Elektor Electronic Toolbox is a collection of no fewer than 28 electronic tools that can be picked from a comprehensive set of icons.
The toolbox includes extensive databases for bipolar transistors, triacs, thyristors, diodes and ICs. Of course you can scroll through the long lists with one finger, but it is also possible to run a search. After touching a part number, key specifications of the relevant component appears including the connection details. There are more than 45,000 components to be found. There is also a separate database with connection data connectors for audio / video, computer and telephone applications. [via]
