Shrediquette - a multirotor MAV by W. Thielicke. EasyDriver v3.1 Tutorial. Update: I've posted a new Easy Driver 4.2 Tutorial for those who are using the new design. A quick tutorial on how to get things up and running with the EasyDriver v3.1 Stepper Motor Driver Board. A big thank you to Brian Schmalz, the designer of this board.
It's obvious why he has called it the EasyDriver. It was indeed, an "EasyDriver" to set up ;) PLEASE NOTE: some people have overlooked the extra (ground) pin on the easydriver board. WARNING Easy Driver v4.2: Please do not attempt this tutorial with new Easy Driver v4.2 board.

Teensy USB Development Board. The Teensy is a complete USB-based microcontroller development system, in a very small footprint, capable of implementing many types of projects. All programming is done via the USB port. No special programmer is needed, only a standard "Mini-B" USB cable and a PC or Macintosh with a USB port. Update: Discussion / Support Forum Teensy 3.1 changes from Teensy 3.0 Teensy Loader Application Software Development Tools WinAVR C compiler.
Teensyduino, add-on for Arduino IDE. Simplified USB Examples or Dean Camera's LUFA library. Breadboard Usage The Teensy is available with header pins, for direct no-soldering-required use on a breadboard, which can also be run from the +5 volt from the USB cable. The 128x64 Graphics LCD can be used with Teensy 2.0 and Teensy++ 2.0 and Teensyduino using this GLCD library. Submarine Cable Map. Freebox Open Source Software. GSM/GPRS. Blog » GM862-GPS. Interfacing Arduino with a Telit GM862. The Arduino can talk over a wide range of networks. Ethernet, Bluetooth, Wifi, XBEE and GPRS to name the most known. I had a Telit GM862-GPS module laying around, unused for some time already. It has GPRS and GPS capabilities, both accessible with AT commands. So I decided to port some of my code to the Arduino. Schematic Connecting the Arduino Mega to the GM862 is rather easy. Tx3 – TxRx3 – RxPin 22 – On/OffGND – GND The GM862 is accessed with a breadboard fiendly breakout board from Sparkfun.
The logic pins of the GM862 accept only CMOS 2.8 Volt. The bad thing for this setup is the power supply. Software First I wanted to use an Arduino Pro mini, that runs on 3.3 V. The following features are implemented: Starting and stopping the moduleInitializationSending of SMSRequesting GPS position and parsing the resultOpening a socket, writing and reading (used to talk HTTP) over GPRS The software is an really early stage.
Log Here is a log, that I recorded within the Arduino IDE. Outlook. [Linux] Beagleboard GPS+GPRS (cellphone) Module. – 08/06/2011Posted in: General, PCB, PCB, Space Camera This is my design for a GPS/GPRS module that integrates and stacks upon a Beagleboard. You can talk to it and power it through USB (or alternative). You can request GPS positions, place calls, textmessages, post to HTTP/FTP servers, HTTP requests, the whole shabang. The PCB design in currently in production in shanghai [white PCB color], due to arrive the end of July. They cost around $2 a piece, i ordered 10, so i have too much (any volunteers can have one if they like).
Anyway, the GPRS/GPS module itselfs costs around $90, and the rest of the chips around $10~$15. Ofcourse, you’d have to solder everything yourself. Module This is the module it is all about, it’s a fairly cheap integrated GPRS & GPS module. GPS/GPRS module ~$90 Printed Circuit Board Design Top Bottom (Oh yeah it's Rembrandt on the silkscreen.
Schematic Schematic FYI: prototype Fully operational prototype About Tim Zaman. [Linux] Beagleboard GPS SMS Cellphone Module ready! This board i made for the Space Camera Live project, as a backup GPS system, that can also send SMS messages and make some calls. Most importantly, it can get python scripts loaded to it. For instance, you can call it up (it takes a sim card) – then ofcourse it will not pick it up, but it will send you back an SMS message immediatelly containing its GPS coordinates! This module is spaced such that it can be hooked up to the Beagle Board easily, it has the same hole dimensions and sizes as the board. Also, ofcourse, this board can be used with any machine that has USB (every machine); so it can also be used as an evaluation board. Not bad for just $3 production costs.
If you want a bare PCB board (this white one) you can have it, i’ll send it over regular email. Prototype without flaws, works 100% This prototype worked out of the box. Module design, schematics, internals, etc I designed this module myself. Rembrandt is pleased Bottom of the module Short Introduction Video Pictures! Close-up. Arduino based DIY time-lapse dolly / intervalometer - Unknown Pixels. The purpose of this post is to provide some basic information about my intervalometer / time-lapse dolly project.

Earlier this year I stumbled upon Arduino and it caught my attention immediately. I was and I am still pretty new to electronics. Code and documentation (electronics) The project’s code is open source and it’s licensed under MIT license. I found it pretty hard to get information about certain things while I was building the dolly.
Technical specs Controls Costs The electronics should stay under 110 USD / 80 EUR. The time-lapse dolly I will not provide detailed instructions how to build the dolly. Geekaphone. Pica Pic | retro handheld games collection. Greg's Cable Map. The Verbalizer - An open source board to use with Google's Voice Search for Desktop. With Google announcing the launch of Voice Search for desktop, we couldn’t help thinking that there was even more fun to be had with talking to a computer. So, we went ahead and built an open source dev board to inspire people to build their own useful and wacky contraptions to take Voice Search to another level.
Out of the box, the Verbalizer connects wirelessly to your computer via Bluetooth and when triggered, opens google.com in a new tab and activates Voice Search. An audio notification is played signaling google is ready for your query, which is spoken into the on-board mic. The board is Arduino compatible and we left some I/O pins open, so it's easy for anyone to jump in and create something nutty with it.
To show off the extent of what can be created, we invited some electronics newbies out to our first ever Make 'n Break workshop to share some toys we built with the Verbalizer, as well as to let them have a play. See how it all went down in the video below. COPENHAGEN SUBORBITALS - OPEN SOURCE AND NON PROFIT SPACE. 555 Timer Contest entry – Le Dominoux | Junk'n'Stuff. Winner of the 555 Timer Contest: Artistic category. www.555contest.com Winner of a Fluke Multimeter donated by 555 Timer Contest entry video: Description: Le Dominoux are “LED dominoes”, a blinking LED that propagates from device to device.
Each Dominoux comprises a coin cell-powered 555 timer circuit configured as a one-shot, triggered either by a photo transistor or CdS photocell. Using a bunch of Dominoux enables creating various lighting patterns, trains, and continuous loops. For construction I chopped up RadioShack protoboards into small squares and placed the 555 on the component side and direct-soldered all other components on the solder side. When operating (with the LED off) the power consumption is around 100 microAmps, depending on ambient lighting. I also found that the CdS photocells responded better to red light than green, and they’re more sensitive to ambient light. Improvements: GPS datalogging shield for Arduino.
Would you like to use your Arduino to create geo-locative art? Or make a custom GPS device that can log sensor data along with the precise time and location? Perhaps you're looking to make a tracker, or want to make your own geocaching hardware. You are in luck! Here is my design for a Arduino shield that is perfect for any sort of project or artpiece that requires GPS precision time or location data. This shield supports any of four popular GPS modules and stores data on a standard DOS-formatted SD flash memory card. Simply plug it into your computer when you've finished your data capture and the plain text files are ready for importing into Google Earth, GPSvisualizer, or a spreadsheet. You can build a waterproof GPS logger by putting the shield, Arduino and small power supply in an Otter Box! This photo has notes.
