Before assuming that the title should be “web crawler,” just shush your shussins’ and check out the video after the break. The Pinoccio, as previously noted, is a board in development as a sort of web-enabled by default Arduino. This makes it perfect for a project like this one where a little rover is controlled from 10,000 Kilometers away, or around 6000 Miles for those of us that dwell in the US.
This setup uses a cell-phone accelerometer in Brazil to allow control of this robot in Nevada. Although close, the control isn’t quite real time, so that has to be accounted for. Something like this could be easily used for a telepresence ‘bot.
If you want to build your own, the assembly time is estimated at 1 hour. Instructions, as well as source code can be found on their page after the video. Although the Pinoccio board won’t be available until at least this summer, maybe this will give someone inspiration to try something similar in the mean time! Continue reading “Pinoccio Web Rover”
This cheap and easy hack will let you use your old smart phone to take pictures and videos of the view through a telescope. [Xobmo] built the connector for just 55 cents. Apart from our concerns about scratching the lens when inserting the phone in the bracket we love the idea.
He was given the Celestron Powerseeker 70AZ as a gift from his wife last Christmas. He looked around the Internet and saw that there are already some solutions for recording video using an iPhone 3GS. This design on Thingiverse would be perfect, but he doesn’t have access to a 3D printer and ordering it form a service would cost almost $50. But when he got to thinking about it, all he needed was a ring to fit on the telescope and a way to connected the iPhone to it. He headed down to the hardware store and picked up a PVC coupler. After working with a hack saw and drill he ended up with a slot with two wings on it. Just slip the phone in and slide the ring on the eyepiece. You can see some action shots, and get a look at the mount itself, in the clip after the break.

Just the other day we were reading a Reddit thread asking about how to control a television with a smartphone. The conversation started by talking about adding an IR LED to the phone. Then it was suggested that there should be standalone Bluetooth devices that convert commands to IR, and came around to the ideas that TV’s should ship with native Bluetooth hardware. We couldn’t agree more but we’re also not about to replace our TV just for this option. That’s why we were delighted to find this project waiting on our tip line. It’s a method of controlling a camera shutter from a smartphone using Bluetooth. But the technique will work for any device which uses an infrared remote control.
The video after the break shows two different devices controlling the camera shutter. As you can see in the diagram above, the iPhone is the master controller, connecting to a Bluetooth headset mounted on the camera. That headset was altered to feed the speaker connections into an IR LED pointed at the camera’s receiver. The iPhone plays an encoded audio track matching the IR remote command, resulting in the properly formatted message flashing on the LED. The watch doesn’t have the ability to playback audio, but it can send a message to the phone, which then plays the proper audio track through the headset.

[Becky] wrote in to tell us about her latest hack for Adafruit Industries. This hack will allow you to light up the Apple symbol on the back of your phone, and as she notes, it will definitely void your warranty. From the looks of the video, it requires some extremely good soldering skills, and optionally mid-level tape skills. If you’re up to the challenge, and have the stomach to see your iPhone on the operating table, the results are quite good.
One other challenge of doing this hack is that it uses a kit that Adafruit isn’t going to sell since it uses knock-off Apple parts. They exist somewhere, but where to source them would be a challenge. On the other hand, from a purely experimental/engineering point of view, the video after the break is quite interesting. Many of us would be very hesitant to take apart a several hundred dollar phone, much less solder to a power supply on it!

The Raspberry Pi foundation is in a somewhat unique position. They always test the units that get returned to them in hopes that they can improve the design. They often request that the power supply also be sent back with the RPi unit, as we know the board will not work well if the PSU can’t source enough current. And so they’ve been able to get a look at several counterfeit iPhone chargers. This is not one of the recommended ways to power the RPi, but their ability to collect failed hardware means that they have identified three different fakes on the market.
Seen here is a genuine Apple product on the left. The others are fake, with the easiest way of spotting them being the shiny chrome plug connectors. The genuine part has a matte finish on the connectors. There is also a difference in the chamfering, and even a variation on the orientation of the USB port on some of them. Unfortunately we don’t get a look inside, which is what we really wanted. But you can see in the video after the break that weighing the adapter will also give it away as a fake, showing that the components within probably vary quite a bit. This reminds us of some other fake PSUs that have been exposed.

[Will Powell] sent in his real-time subtitle glasses project. Inspired by the ever cool Google Project Glass, he decided he would experiment with his own version.
He used two Raspberry Pi’s running Debian squeeze, vuzix glasses, microphones, a tv, ipad, and iphone as the hardware components. The flow of data is kind of strange in this project. The audio first gets picked up by a bluetooth microphone and streamed through a smart device to a server on the network. Once it’s on the server it gets parsed through Microsoft’s translation API. After that the translated message is sent back to a Raspberry Pi where it’s displayed as subtitles on the glasses.
Of course this is far from a universal translation device as seen in Star Trek. The person being translated has to talk clearly into a microphone, and there is a huge layer of complexity. Though, as far as tech demos go it is pretty cool and you can see him playing a game of chess using the system after the break.

At the beginning of the school last year, [Ryan] needed to come up with a project for his master’s thesis. Having a bachelor’s in mech. engineering and doing his graduate work in software engineering allowed [Ryan] to do something really cool for his thesis; he decided to turn an iPhone into an autonomous robot with live video streaming, remote control, and object detection.
[Ryan] started building his ArduiPhone last October with an Arduino, motor shield, and a Magician Chassis. The software is based on an iPhone network programming tutorial that opens a socket connection to a desktop PC and relays commands to an Arduino serial port.
One of the more interesting features of [Ryan]’s ArduiPhone is the ability to stream video directly from the phone to a Java application. Instead of FaceTime, [Ryan] streams videos by converting an image from the front-facing iPhone camera to a byte array, sends it over the network, and decodes the image in a Java app. It’s low-level stuff, but the video quality is excellent and something we’ll probably be seeing more of in the future.
As always, videos after the break.
