My Bookmarks for 11/06/2010

  • Get the guide and the Arduino all in one! Includes our best-selling Getting Started with Arduino book by one of the co-founders of the Arduino project, plus an Arduino Uno microcontroller.

  • Every MadLab kit includes a professionally-manufactured printed circuit board, quality components, and full assembly instructions.

  • Electroids are electronic hobby kits; you probably figured that much out already.
    Each Electroids kit comes with all the components needed to build fun and useful projects and include informative, easy-to-read instructions that explain the why, not just the what. Ever look at a recipe and not been content with just being told what to do and not being told why? I have, and I make sure that all my instructions leave nothing as a mystery. Every step is described plainly and its purpose is outlined expressely.

  • In order to get raw parsed data out of a magstripe reader, we first experiemented with a MAGTEK Centurion Keyboard Encoder (PN-21073062). We found that although we could get all 3 tracks of data, it was not possible to have it parsed out. We then purchased a raw magstripe decoder head with track 1 reading, the Omron V3A-6 (Datasheet here). By writing some parity checking code, we were able to read the raw data off of the magstripe, and parse it into output that would be 'typed out' as an emulated keyboard using a USB-enabled Teensy. An Arduino can also be used, and the data would be output as Serial which may also be useful.

  • This is a basis for how one may go about setting up an electronics workbench in a company or well-equipped home shop.

  • This project documents my adventures in learning how to wire up my home for wireless power monitoring. I live in a rented apartment so I don't have hacking-access to a meter or breaker panel. Since I'm still very interested in measuring my power usage on a long term basis, I built wireless outlet reporters. Building your own power monitor isn't too tough and can save money but I'm not a fan of sticking my fingers into 120V power. Instead, I'll used the existing Kill-a-watt power monitor, which works great and is available at my local hardware store.

  • Serial ports are being phased out...but USB microcontrollers are still hard to use, and require custom drivers. Using a USB to serial adaptor board overcomes both of these issues, as USB ports are standard on every computer, hubs are inexpensive, and these boards use a chip that is supported by MacOS/Windows/Linux.

  • This project details how to build a Smart/SIM card reader/writer for experimentation and investigation of SIM & Smart cards.Once the reader design is built, the open source software can be used to read from and write to the card. Together they can be used to backup/restore stored SIM card data, recover deleted SMS's and phone contacts, examine the last phone numbers dialed, etc.

  • This tool lets you simulate keyboard input and mouse activity, move and resize windows, etc. It does this using X11's XTEST extension and other Xlib functions.
    Additionally, you can search for windows and move, resize, hide, and modify window properties like the title. If your window manager supports it, you can use xdotool to switch desktops, move windows between desktops, and change the number of desktops.
