Pi Tin clear enclosure for the Raspberry Pi

The Raspberry Pi is everybody's favorite little computer, the last thing that you'd want is for something bad to happen to it. Why not protect it with one of these snazzy plastic enclosures? These cases protect the Raspberry Pi from things like rogue wires that might short it out while still allowing full access to the board! Simply snap the RPi into the bottom half of the enclosure, then snap the two sides together.

The enclosure provides slots to access the peripheral header, USB ports, Ethernet, SD card, HMDI, composite video, audio, CSI and JTAG connectors as well as feet and vents to ensure the board gets proper cooling and plus-shaped wall mounting slots. All of the status LEDs on the Pi are visible through the case thanks to light pipes embedded in the design. This is a really slick case and once you've gotten your hands on a Raspberry Pi, you'll want to snag one of these to put it in!

Dimensions : 9.5 x 6.2 x 2.7 cm

MP3 Player Shield

MP3 player shield retains the awesome MP3 decoding abilities of the last version but adds the storage functionality of the SD card shield. Now you can pull MP3 files from an microSD card and play them using only one shield, effectively turning any Arduino into a fully functional stand-alone  MP3 player! The MP3 Shield still utilizes theVS1053B MP3 audio decoder IC to decode audio files. The VS1053 is also capable of decoding Ogg Vorbis/MP3/AAC/WMA/MIDI audio and encoding IMA ADPCM and user-loadable Ogg Vorbis.

Features:

• 3.5mm audio out jack
• 0.1" spaced header for speaker out
• microSD card slot

Axon atmega640 microcontroller

The Axon was developed for robots that go beyond the basics. With the Axon, you will no longer need to worry about not having enough I/O as it has 55+ for you to use - up to 16 ports for analog sensors, and up to 18 for interrupts. You will never be wanting of UART, as there are 3 directly available, with a 4th used for a USB connection directly to your PC. No additional programmer needed due to a built in programmer (bootloader). Lastly, extensive source code and tutorials have been developed to make it easy enough for a beginner.

More specifically, the Axon is the best microcontroller on the market for multi-limbed robots such as bipeds, spiders, and robot arms. Unlike many other robot microcontrollers on the market, no additional wiring is required. It is 100% plug-n-play - no external power buses required to plug in servos or sensors, literally taking minutes to set up.

The Axon uses the powerful ATmega640 as its processor, which has typically 4x more memory than other controllers on the market (see specifications below).

Lastly, at 34 grams (a typical 9V battery weighs 40g), the Axon is the smallest and lightest of any other comparable full-featured microcontroller on the market.

BOB4-HG-Fourth generation header style OSD module

BOB-4-HG (header connector version) module for NTSC or PAL video.

BOB-4 is the 4th-generation low-cost video information overlay module. BOB-4 lets your microcontroller or PC display text and vector graphics on standard TV monitors. With huge user-definable character sets*, BOB-4 also supports bitmap graphics and multiple languages. BOB-4 generates background video on-board, or automatically genlocks to your video source and superimposes characters over the image. Printable characters and commands control BOB-4 through a fast RS-232 style data link, much like a serial printer. BOB-4 links directly to most microcontrollers. NTSC and PAL video standards are supported in a single hardware version. Field firmware upgrades are supported via PC connection.

Previous versions of the BOB family have relied on 3rd party OSD chips for part of their functionality. These chips were once common in the days of analog video systems (VCR) but have now become obsolete. BOB 4 is a complete custom design that does not rely on 3rd party technologies. This will ensure that the BOB 4 will be a stable platform for quite some time.

Features:

• Simple hookup; requires just 5VDC, serial data, video I/O
• Immediately prints plain ASCII text in default configuration
• High display density; up to 480x240 (NTSC) or 480x288 (PAL)
• Arbitrary custom font sizes and proportional font support

• Off-board memory expansion for huge fonts & bitmap graphics
• Industry-standard ANSI command protocol (ECMA-048)
• Automatic vertical scrolling
• Text crawl (single-line smooth horizontal scroll)
• Mirror-image reverse text display capability
• VBI (vertical blanking interval) data insertion
• Async (RS-232 style) and SPI control ports
• Automatic video mode control (local/genlock)
• Customer-configurable video standard (NTSC or PAL)
• Stand-alone operation for video source ID, target reticle, etc.
• Software-controlled digital logic outputs (5)
• Analog voltage inputs (two 10-bit ADC channels; BOB-4H only)
• Consumes only 1/2W at 5VDC
• Lead-free and nominally RoHS-compliant
• Designed for maximum production lifetime; no OSD chips!

• BOB-4 configuration memory management
• BOB-4 firmware upgrade utility
• One-click BOB-4 module configuration

OpenLog is an open source data logger

OpenLog is an open source data logger. Simple to use, simple to change. We wanted to create a serial logger that just worked. Power up this device and it will start logging any received serial data at 9600bps. Sending Ctrl+z three times will drop out of logging and in to command mode. 'new' will create a new file. 'md' makes a directory. '?' brings up the list of commands. OpenLog doesn't do a lot, but it does log serial streams extremely well. Example:

>new testfile.txt
>append testfile.txt
<(send large amounts of text followed by three ctrl+z characters)

That's really it! OpenLog firmware is open source and is based on Bill Greiman's sdfatlib. OpenLog currently supports FAT16 and FAT32 microSD cards (we've tested up to 16GB!).

All the design files (schematic, PCB layout, firmware) are open source released under the CC-SA v3 license and are available through GitHub.

Note: New firmware is available which allows the OpenLog to be used in Arduino 1.0 and also allows for higher baud rates. Check the links below for more information.

Features:

• Log to low-cost microSD FAT16/32 cards up to 16GB
• Simple command interface
• Edit config.txt file from a computer to change baud rate and other system settings
• Three modes:
• NewLog creates a new log every power up and immediately starts logging
• SeqLog appends a file called "SeqLog.txt" at every power up and immediately starts logging
• Command mode starts OpenLog at a command prompt at power up
• Configurable baud rates (2400 to 115200bps)
• Configure unit through config file or the menu system
• Power, ground, and RX-I are the minimum connections
• Reprogrammable ATmega328 using the Arduino IDE
• Two LEDs indicate writing status
• Input voltage from 3.3V to 12V
• 2mA idle, 6mA at maximum recording rate
• Dimensions: 0.16 x 0.6 x 0.75" (4 x 15 x 19mm)
