This guy took the spinning POV idea one step further and added them to his helicopter’s rotor. There’s good control over the display as you can see in the few videos he has posted. The article has the source files of the software and hardware used to build the project, so take a look and build your own!

“The unit is designed to function (user configurable) either as a temperature alarm or a thermostat – the only difference being that with an alarm an intermittent beep is produced when a limit is exceeded.” The open source hardware schematic and PIC software are provided in the article, along with an in depth explanation of how the system works.

Don’t let the phantom power scare you away, this mic is powered by the music flowing into it. “The circuit is constructed on a Radio Shack Multipurpose PC Board (Cat # 276-150) which has been modified by snapping off about 1/2″ of its length to provide clearance for the two DIN sockets.”

“September 2009, Quattrino’s project started as our Mechatronics Engineering graduation project in the German-Jordanian University. Quattrino or Quadrotor (which is the common name for it) is an aircraft classified as rotorcraft, lifted by four rotors and able to vertical take-off & landing (VTOL).” The project article has all the hardware, electrical and software details so go build your own!

To go with my other vga oriented projects here’s a VGA interface that is built entirely with TTL discrete logic chips. I built it primarily for the 7400 contest over at dangerous prototypes, so give a comment over there if you like the design. This interface outputs the proper Hsync and Vsync signals using some 74193 counters and uses an 8-state machine to output different color signals to an LCD.

Another data logger! This one uses a PIC to load GPS points into an EEPROM and when you’re done you can unload the points into your PC through a serial port, put them into google maps and get a map of where you (or the data logger) traveled. Would be cool to put one of these into the mail and see how efficient the mail system is. The article is in dutch so use google translate for english.

“This cheap and easy to build NiCd/NiMH Battery Charger is suitable for automatically charging a wide range of batteries for many applications. Proper chargers are usually expensive and cheap chargers supplied with the original equipment often incorrectly charge the cells and dramatically shorten their life.”

“Using the super awesome TouchOSC app for the iPhone connected to Processing for converting Open Sound Control signals into serial commands send out via USB to an Xbee…I am able to drive a small tank.”

“After visiting some web pages about 2.4 GHz ISM band spectrum analyzers based on the CYWM6935 module, I tried to build my own analyzer, but with some improvements. The references I found on the net used the parallel port or a serial link to a host computer. I want the analyzer to be portable, and easy to transport, so I will use a microcontroller and a graphical LCD.”

The Basic Stamp is nothing much more than basic. Because of this, it offers a unique opportunity for anyone who wants to learn about embedded devices because it’s functionality is so simple. This article takes a look at how to get started with Parallax’s Stamp-1 module and what to expect from this little guy.
