IOS Terminal Debugging Tool

September 13, 2012 by Mike Szczys 8 Comments

This is a simple iOS debugging tool that will take no time to solder together. There’s even a chance that you already have everything you need on hand. The hack simply connects an RS232-to-USB converter to a breakout board for an iPod connector.

The hardware is aimed not at stock iOS systems, but as an aid to those who wish to run alternative operating systems on them. When the OpeniBoot package is run on an iPod Touch or iPhone it enables a serial terminal on pins 12 and 13. The FTDI breakout board takes these as RX and TX and makes them available to your terminal program of choice via USB. Speaking of USB, you may already have noticed the black cable leaving the right side of the image. Using the terminal doesn’t limit your ability to use the device’s USB functions.

Using A Raspberry Pi As Your Travel Computer

September 11, 2012 by Mike Szczys 29 Comments

Do you think you could travel for the entire summer and leave your laptop at home? [Gef] did just that. With the help of his Kindle he used a Raspberry Pi as his travel computer. This was an easy association to think up, since he planned to bring the Kindle along as his reading material anyway. All it was going to take was some creative hacking to get it working as a display for the single-board computer.

The Kindle is merely connecting to the Raspberry Pi through a terminal emulator. This happens via USB, and requires that you Jailbreak the kindle and install a package called USBnetwork. The problem with the technique is that you’re going to go crazy trying to use the tiny keyboard that is built into the eBook reader. [Gef] decided to take a USB keyboard along with him, but how is he going to use it to control the terminal screen on the Kindle? The answer is the ‘screen’ application. We’ve used it a lot to keep programs running on a machine after we’ve exited from an SSH session. It turns out it can also be used to host multiple users on the same terminal session. Pretty neat!

Retrotechtacular: 1983’s Answer To Information Overload

August 21, 2012 by Mike Szczys 37 Comments

We can’t say we ever really thought that the problem with the early 1980’s was too much information in the hands of the people. But this promotional video for the Sceptre Videotex Terminal claims that it is the solution to the information overload of the time. The entire video is embedded after the break.

You use your TV as a display, connecting the hardware to a phone line and using a keyboard for navigation. Perhaps our favorite bit is when the announcer informs us that the secret behind the system is its “vast sources of information”. These include the Miami Herald, the Associated Press, the Wall Street Journal, and Consumer Reports. Just remember that at the time you’d need to hit the local library to access all of those resources. Also, searching them wasn’t a possibility.

But wait, this wasn’t just conceived for news. The system — which was backed by Night-Ridder (a huge Newspaper conglomerate) and AT&T — boasted commerce and banking abilities as well as education services. It’s the vision of the Internet which Ma Bell would have preferred to be in place today.

Android Phone Serves As Arduino Terminal

September 13, 2011 by Mike Szczys 9 Comments

Looking to use his Arduino when on-the-go, [Oleg] has been working on a way to use the Android ADK terminal emulator with the Arduino. The Android side uses ADK features along with a custom application. [Oleg] received help from his friend [Victor] when developing the program for Android (you can check out our own Android Development tutorials if you’re interested in learning how this is done). The .apk file is available for download, but they’re waiting to release the source code until they can clean it up and get some of the gnarly bugs out of the beta version.

A USB host shield for the Arduino is needed to connect to an Android hand set. You’ll be able to send and receive strings via the terminal, with support for carriage return and life feed characters. Unfortunately this doesn’t allow you to change, compile, or write sketches to the Arduino. But it might come in very handy when trouble shooting a project when a computer is not around, or just for using an Android phone as an output.

Add A Real Life Hardware Terminal To That Newfangled Computer Of Yours

If you find a crusty old IT guy and give him half a chance, he’ll probably regale you with stories of how things were done “in the old days” where no one had their own computer and everyone worked on mainframe-connected dumb terminals. [JSTN] yearned for a true to life terminal display that he could attach to his 2010 Mac Pro, and since there’s no chance anybody is bringing one to market any time soon, he pieced one together on his own.

He dug up a digital VT220 terminal, and got to work trying to interface this office relic with his shiny new Mac. He found a few helpful tips from someone

I Am Root! – IP Camera Shell Access

June 3, 2011 by Mike Szczys 26 Comments

[Shawn] emailed us some pictures and a description of his latest hack. He cracked open a Rosewill RXS-3211 IP Camera because the output of the web interface made him certain that it was running Linux and he wanted to unlock some more potential from the device. These cameras are used for security, and offer a browser-based interface via a WiFi connection. After studying the circuit board he started poking around an unpopulated set of four pads and managed to get a serial connection up and running. The device’s serial terminal operates at 115200 baud using eight data bits, one stop bit, and even parity.

He wonder where to go from here and we have a few ideas. You can see in the terminal readout above that it announces when motion is detected. We think this motion detection would be quite useful with a small rover while adding live video broadcasting at the same time. An embedded Linux system should be able to interface with the device and we think that a bit of creative coding would open up the WiFi connection for other use as well. Not bad for a module that can be had for as little as $29. We’ve included all the images [Shawn] sent us after the break and we’d love to hear your thoughts on what you’d use this for in the comments.

Kindle Terminal With Secret Key-press Activation

December 10, 2010 by Mike Szczys 26 Comments

[Luigi Rizzo] has been working on some hacks for his 3rd generation Kindle. There is already a Python based terminal emulator called AjaxTerm but he wanted a lightweight standalone so he reimplemented the program in C. The 100k binary monitors the keyboard, launching the terminal emulator when it detects a Shift-T sequence. It also uses alternative key mapping to fill in for some of the keys the Kindle’s keyboard is missing.

We haven’t seen a whole lot of Kindle hacking since it was hacked to run Ubuntu. Seems like this terminal emulator is a useful and unobtrusive hack to try out on the beloved reader.
