With the new device Lantronix xPrintServer you can print documents on your network printer from any Apple iOS mobile device.

Imagine, in your company you have a visit with some Apple mobile device like iPod, iPhone or iPod touch and your visitor from any reason needs to print some document. A problem is, that with a probability near to surety, in a given mobile device no drivers for your printer will be installed.

This problem is elegantly solved by a new device from company Lantronix – xPrintServer. It is a literally „plug´n´play“ or „plug´n´print“ network device. xPrintServer serves as an „interface“ between a mobile device and a printer. Apple iOS device communicates with a network through your company´s WiFi and the xPrintServer sends data to a network printer through an ethernet cable.

In comparison to other common net devices, a configuration is unbelievably simple. Connect the xPrintServer into your LAN through an ethernet cable (to a router, switch, hub or any place in the network), power up the xPrintServer, and the xPrintServer will auto-discover and auto-provision all printers in the network. No other configuration is necessary, no applications or any other software. All that is necessary to do to print is to sign into you company´s WiFi with a mobile device, open a desired web page, e-mail, photo etc. and choose the icon to open the native print menu. Then from the printer options menu, choose a printer through which you wish to print. Finally, select a number of copies and choose „Print“.

Detailed information will provide you the Product Brief, user guide – Quick Start and the List of supported printers.

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.

Mike Colagrosso created Avviso, a Processing and Arduino library for sending push alerts to iOS devices using the Prowl API. This would make projects such as Snail Mail Push Alerts a much easier task because a PHP web server is not needed in the set up. The libraries, example code, and set up guide are available on Github.

This is a cool project with comprehensive explanations helpful for newbies. [via]

Mike’s app melds Apple iOS stuff with an Arduino: [via]

I wrote an iOS app find my Arduino over Bonjour and talk to it. It’s call Ciao, and the App Store approved it last Thursday.

Ciao makes it easy to talk to your Arduino from your iOS device. Load one of the example sketches onto your Arduino, and Ciao will automatically find it over Bonjour. You can use Ciao to control your Arduino or get live information from your Arduino.

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.
