This board is intended to lower the cost of getting the arduino connected to the internet. I will upload the board drawing to my github after I have fully tested it and corrected my mistakes. The foot print for the arduino is a standard pro...
Uploaded v2r2 to github with the copper pour. Sparkfun got new SD card holders in stock so I will redraw this board starting with the schematic and start over for r3.
While I was waiting on boards and parts I started assembling this. My answer to the Nest thermostat, ugly isn't it. Since I got an email yesterday that sparkfun is filling my order for sd card holders and I have 9 more boards to use up I...
ok so this project has been resurrected, the following is a list of things I would like to do / add to this project1) Cross platform support (windows, mac, linux)2) Allow command line arguments so i can run a script without a UI using java -jar DuckyEmulator.jar...
A lot of embedded/home-automation server demos and tutorials with WiFly and arduino use html forms with submit buttons on their websites to send HTTP 'GET' or 'POST' requests to change an output on the arduino, and in turn reload the entire page with...
So I have been quiet of late, and I thought it was about time I explain myself.DistractionsTo start with, I have this little cheeky girl growing her first few teeth:Which has been a bit more stressful than normal, with less sleep and less time to work...
Sorry to say, the SD card slot transplant for the Pi failed, and the poor thing never woke up from surgery.(I should stick to through hole!).So in its place, I am digging out this old little system to stand in for the hub for now:It wasn't what I had...
Stepper driverI have finished the firmware for the stepper controller. This is a separate microcontroller which receives commands from the main microcontroller over UART. Each command consist of which axis to move, which direction and how many microsteps...
One of the advantages to using the Pixhawk is the ability to create custom control configurations. This is necessary for Goliath since it's using a single engine with variable pitch propellers. Previously, having a custom mixer wasn't necessary...
The emulator now lets code access the SD card using I/O instructions. One of these instructions tells the Arduino to load a binary file into the emulated memory. This is nice, however the memory array is stored in RAM, so it is very limited in...
Similar in spirit to the label maker, I am adding another incidental machine to the network to allow more flexible and complex usage. A simple garden watering valve. It broke, so instead of replacing it I thought I would use the opportunity...
I've been holding off on an official component list until I can stabilize the build a bit more, but I wanted to mention a few things that have occurred since the original plan was hatched, and some of the design decisions involved.Without delving too...
I downloaded the latest raspbian (that's 2014-01-07-wheezy-raspbian), dumped it on an SD card and the pi was running immediately. Also configured the I²C bus following the adafruit description. After attaching a PCF8574A to the bus, I could successfully...
I would like to take this project further by adding more features to the computer and would like to get the communities opinion on the sort of features which should be included in a future version. Adding more features most likely means moving away from...
USB: The camera is USB powered, there are lots of app notes on USB interfacing to read, but here are some tips that I've learned: match the deferential pair, use terminations(1) , use a ferrite bead on VBUS, limit the inrush current...
