For a full tutorial on making a generic arduino clone, check out the perfduino . The plantduino is an customized version of the perfduino.

Tip #1 : Breadboard before you solder! Make sure your parts can work before you melt them to metal. Tip #2 : Go through the pictures and read the tags.

Tip #3 : I chose a large perfboard for this project because of all the external connections. Make sure you leave room in your layout for the LCD. Tip #4 : Analog inputs are on the right. Digital outputs are on the left. I did this because the analog pins are all on the right of the atmega chip. Tip #5 : Start with the power supply. This will determine where you place other components.

Tip #6 : While soldering the male headers to the LCD ribbon cable, keep them set in the female headers. This will prevent them twisting around in the heated plastic. Tip #7 : While every component is important, the 100nF capacitor and 10k resistor coming from the reset pin (pin 1) are absolutely vital! Your plantduino will not program without them!

Tip #8 : Connect the LCD wires on the back side of the board! It will save a lot of space and make it possible to examine your board for more than five seconds without losing normal human cognitive ability.

Tip #9 : This power jack will save you space. I got the large one for the sake of shipping costs.

2. DO not forget this 100nF capacitor! you need it to allow programming communication.

Step 18: Birdhouse: Creation and Installation

We bought a birdhouse from Michael's Craft Store to put all of the electronics in. You can use whatever enclosure you feel works for your home or environment. Here is what we did.

Materials:

1 wooden house cd holder- unpainted- Micheal's Craft Store

Oil paint Paintbrushes Drill Screwdriver Nails (any size) Screw (any size) Hacksaw

Plywood Sheet (16 inches by 14 inches)- from Micheal's craft store Hinges- bought from home depot

Magnetic door clasps- bought from home depot Clear Plastic Portfolio envelope

Steps:

1) Paint the Birdhouse: We used oil paints because they are harder for the rain to wash off. Be warned, they take a very long time to dry. 2) Cut the doors: Using a hacksaw I cut the doors out of a piece of plywood.

3) Attach the hinges- I bought a pair of really small hinges at home depot. The screwed on side of the birdhouse and then on the side of the doors.

4) Glue on the Magnetic Door Clasps- The magnetic clasps keep the doors shut. However, the magnets are very strong. You can increase and decrease the force of the magnet by limiting the exposure the magnet and the clasp have. We just hot glued these two pieces on.

5) Weatherproof the birdhouse- We used the plastic from a clear plastic portfolio envelope to coat the windows and other exposed areas of the birdhouse.

6) Cut holes- We used a drill to drill two holes into the bottom of the birdhouse and two in the second story floor. The holes on the bottom floor of the birdhouse are for the wires from the nails and the thermistor in the greenhouse that are connected to the Garduino microcontroller. The wires connecting the relay box to the micro-controller go through there too.

7) Nail the birdhouse to a sturdy spot- We nailed the birdhouse to the support beam on my deck. We nailed the bottom and the back to make sure it won't blow away. 8) Put the relay box into the birdhouse. We put it into the bottom floor. We strung the power cord through one of the windows of the house.

Step 19: Creating the Birdhouse Motherboard

Image Notes

1. We nailed the board to pieces of wood that are offset from the back for easy access to the screw terminals

2. Relay box goes into the bottom shelf of the birdhouse

3. Wallwart that is connected to the solenoid valve (make sure it is plugged into the right outlet!)

4. cord from relay box going to outdoor extension cord

Image Notes

1. LCD screen displaying temperature and watering status of the greenhouse, including Celsius and F readings.

Image Notes

1. Transparent plastic protecting the screen from water damage 2. snake cords through the windows

Image Notes

1. make sure to snake the irrigation tubing in the garden so that all the plants are watered equally

Image Notes

1. oil paint not running even in the rain!

Image Notes

1. place the moisture sensors in a place that is representative for the entire garden

Step 21: Final Thoughts/ Additional Reading

Adding Light and Temperature regulation:

This link shows how to include photoresistors and 10K thermistors as analog inputs. Using these tools you can regulate the light and temperature of the greenhouse. For more information:

The EyeWriter 2.0

by thesystemis on December 1, 2010

Intro: The EyeWriter 2.0

The EyeWriter is a low-cost eye-tracking apparatus + custom software that allows graffiti writers and artists with paralysis resulting from Amyotrophic Lateral Sclerosis to draw using only their eyes.

The original design, as shown here, featured a pair of glasses as the basis for the eyewriter design:

Since that first video, we've been hacking on and developing the project, and we have a new design, which we've called "eyewriter 2.0" which improves the accuracy of the device, and allow for people who's heads are moving slightly to also use an eye tracker. The original eyewriter, designed for a paralyzed Graffiti artist TEMPT1, is designed to be worn on a completely motionless head. The 2.0 design, which uses a camera and LED system mounted away from the head, can be used by people whose heads are moving slightly, such as MS patients, and people who wear glasses, etc.

This eyewriter system is cheap, and completely open source. At the moment, it costs about 200$ in parts. Traditional commercial eye trackers costs between $9000- $20,000, so this is a magnitude of order cheaper, and is designed to help anyone who wants or needs an eyetracker.

This fall, we've been showing off and demoing the 2.0 device -- check out the eyewriter 2.0 in action -- we even hooked it up to a robotic arm, to draw the artwork people make with their eyes:

(The 2.0 device was designed with help and input from Takayuki Ito, Kyle McDonald, Golan Levin and students of the eyewriter collab at Parsons MFADT. Thanks also to the Studio for Creative Inquiry / CMU for hosting a session for development)
