A few folks (including us) have iPhone 3Gs units that sometimes say ‘Charging is not supported with this accessory’ – it appears to be a wonky dock connector… jsappo writes –
Hey everybody! I just encountered this same problem and fixed it! It’s a wonky dock connector straight up. I have outlined the entire process for fixing it.. Hit me up with any questions.

The ‘Elektor Electronic Toolbox’ (EET) is an iPhone and iPad app totally geared the needs of electronic engineers. Elektor now offers a new version, which now has 29 individual programs. A new addition is a tool for voltage rms calculation. In addition some bugs were cleared and new components added such as USB 3.0 connectors.
EET’s established features are impressive, too: the databases for the component groups identified as bipolar transistors, FETs, triacs, thyristors, diodes and ICs are very helpful in everyday electronics developing. The left part of the display allows you to select a component from a list, based on the type number. For this, simply scroll down with your finger, which is a smooth process on an iPad. A tap with your fingertip and the pin and important electrical characteristics pop up on the right hand side of the screen – all without an Internet connection present. A total of over 45,000 components are listed in the databases. [via]

Seeed Studio launched an iPhone hardware development board call the Hijack development pack: [via]
Do we have any iPhone users here? What were you thinking when Google released ADK for Android devices? You probably want to have an equal chance to play your mobile devices with open source hardware as we did. The idea of connecting iPhone with those existing open source components is great and more importantly is achievable now with our Hijack Development Pack!
Here is a clue that what the main board of Hijack looks like. It’s a little tiny thing with cubic-inch size so that you can carry it to anywhere you like. But the project itself is a fully functional hardware/software platform for creating sensor peripherals for the mobile devices. The Hijack platform enables a new class of small and cheap phone-centric sensor peripherals that support plug-and-play operation. As we said, Hijack has been tested with the iPhone 3G/3GS/4, iPod Touch, and iPad devices.

Oscium’s iMSO-104 hardware offers to turn your iPhone, iPad, or iPod Touch into a 12MSPS digital oscilloscope with an analog bandwidth of 5MHz. For folks like me with limited desk space & shifting work environments, that’s an interesting offer indeed. Oscium sent over a test model to take for a spin, so onto the spinning!

Calcuccino from Cambridge Coders is a programmers’ calculator that uses the iPhone’s menus and swipe gestures to improve on the conventional calculator. The result is a powerful calculator for programming, engineering and scientific use, with big buttons for fast and reliable entry. Calcuccino features signed, unsigned, and floating-point arithmetic; variable word size from 2 to 64 bits; an interactive ASCII symbol table; bit shifting and rotation; Boolean logic; binary, octal, decimal and hexadecimal notation; bitwise logic; sin, cos, tan, log and square root; and IEEE-754 support.

The iDVM digital multimeter from Redfish Instruments Inc. wirelessly connects to an iPhone, iPad, or iPod Touch to enable users to acquire, visualise and share measurement data on their Apple devices. Unlike conventional multimeters, the iDVM does not have its own display or controls, but instead piggybacks on the iPod, iPad or iPod Touch screen with the aid of a special app. According to Redfish, this novel approach provides instrument users with a familiar user interface that allows them to interact with electronic test and measurement tools in a previously impossible manner.

Pittsford, NY, USA: Saelig Company, Inc. has introduced iMSO-104 – the world’s first mixed-signal oscilloscope that moves Apple’s ubiquitous iOS devices and touch-screen interface into the test and measurement world. iMSO-104 is a revolutionary new 5MHz oscilloscope adapter for iPod touch, iPhone and iPad that is intuitive and easy to use, making it an ideal solution for field service, sales and application engineers, as well as students and hobbyists.
iMSO-104 is designed with a 5MHz bandwidth front-end and a 12MSa/s sample rate, simultaneously analyzing one analog and four digital signals for versatile, time-synchronized troubleshooting. All the usual input, trigger and math features you would expect from a high quality scope are incorporated, including cursor measurements, variable persistence, built-in 3.3V 1kHz reference signal and more. iMSO-104 also adds novel features such as computation power and instant emailing of screen captures. In addition, simple measurements of frequency, period, duty cycle, and reference signal capture are just a touch away. Timebase range is from 2uS – 1S/div, with input voltage display from 50mV – 2V/div. Maximum input voltage using a 10x probe is 40V.
The Hoz writes to inform us of another Arduino related iPhone app known as OTOduino. This free app allows you to interact with an Arduino and monitor/control analog and digital IO ports in real-time via a simple audio jack interface. It’s currently available from the iPhone app store.

To show that iPhone is not just a fashion accessory, as many like to say, read below how to make it a useful device. It is a frequency generator with solid characteristics. Quality will satisfy the needs of amateur electronics and it will be sufficient for the basic measurements and adjustments in audio technology.
