The Ard-Vark is a basic electronics box that can be remotely controlled by an app on your iPhone, iPad or Android phone. It is Arduino compatible. Have you ever wanted to build a project that needed electronics but you didn’t know how to start? Would you like to add motion to one of your creations, and be able to control it with your phone or tablet and not have to learn electronics, soldering, programming and a few hundred other things? Then the Ard-Vark is for you.

A modular device, NODE communicates with smartphones via Bluetooth. Bluetooth requires less energy than Wifi and can send information directly to your Bluetooth enabled device. With new Bluetooth Low Energy, NODE can communicate with iPhone 4S and some Android phones at up to 50 meters with even less energy than conventional Bluetooth. With multiple NODEs networked in your home or office, you can control the different devices by your location.

Tiny, cheap, and dangerous: Inside an iPhone charger. Ken writes – [via]
I opened up a cheap phone charger and examine how the circuit works. In the process, I find that the manufacturer cut a lot of safety corners, and it’s nowhere near US safety standards. There’s a reason that name-brand chargers cost a bit more.
Since you reverse-engineered the protocol for Apple chargers, you will probably be interested in reference #15 from my article… which documents the resistances used by Sony and Apple chargers – their values are
very close to the ones you found.

Will O’Brien developed this project allowing him to remotely start his car via an SMS sent to a jailbroken iPhone. The additional hardware involved is an Arduino, iPhone breakout board such as the PodBreakout Mini, 4x 10k resistors, 1x TIP120 and a 5 volt switching supply cell charger.
All the details, including source code and schematic are available on Will’s Biobug website

A new internet controlled lighting project called SplashLight is being developed. It has 4 relays to turn lights on and off, and 3 PWM outputs to drive RGB LEDs. The core of the project is a Cortex M3 uC with an Ethernet PHY/MAC from Texas Instruments.
The project includes iPhone, Android, and web applications to control the board over the web. It looks like the PCB and schematic files will be made available in the future, but the license is still unannounced. Might be ripe for a remake.

SAN FRANCISCO – Apple Inc is famous for relying on low-cost Asian manufacturers to both source and assemble its popular gadgets, but the consumer device giant recently started receiving a critical component in its iPad and iPhones from closer to home – Texas.
The A5 processor – the brain in the iPhone 4S and iPad 2 – is now made in a sprawling 1.6 million square feet factory in Austin owned by Korean electronics giant Samsung Electronics, according to people familiar with the operation.
One of the few major components to be sourced from within the United States, the A5 processor is built by Samsung in a newly constructed $3.6 billion non-memory chip production line that reached full production in early December.
Nearly all of the output of the non-memory chip production from the factory – which is the size of about nine football fields – is dedicated to producing Apple chips, one of the people said. Samsung also produces NAND flash memory chips in Austin…

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 »

Yep, that’s right, the book of iPhone schematics. I snapped that baby up for $4. My feeling is that these schematics probably come from leaks of original Apple sources, because many of the annotations couldn’t be divined from a clean-room reverse engineering job. For example, the above schematics annotate that the AP_UART connection on the dock has a dual-footprint option for a possible drop-in DisplayPort upgrade. Anyways, these schematics are useful as a sourcing guide for cheap components. Any part found in this book has been made in millions-per-week quantities, which is a handy fact to keep in mind when bargain hunting for stable supplies of cheap components.

RGB LED turn signals… StarfireMX writes – [via]
Well I posted a video of my finished turn signals, everything seems to be working well and have over 6000 miles driven with them through about 10 states, not one problem. I would ultimately love to control them from my iPhone, and I am looking into ways of doing this use WiFi or even the cell network (I would incorporate more in to the system if I did this with cell connectivity) I tend to lean to the WiFi system it’s cheaper and draws less power. I might end up switching the system to a keyed power source so it is inactive when the car is off but for now this works.
