Have you ever been skiing and reached a cliff and wondered how high it was?
Have you ever been moving furniture and needed to figure out how much space you had but didn't want to deal with the annoying tape measurer?
Well worry no more! This is the Southpaw. A tape measurer and a glove all in one!
Using simple modern technology this wonderful new device may just be exactly what you are looking for.
The Southpaw is a fairly simple device in theory but much more difficult to actually make work. It collects data from a sonar range finder, converts that data to a distance, and displays the distance on the built in LCD screen. Lights on the tip of the fingers indicate that the microprocessor is receiving power and provide a very esthetically pleasing addition to the Southpaw.
Step 1: Cut Open the Glove
Next, sew a zipper (you can find one at any hardware store) into the slit, so that you can access the internal components for troubleshooting/repair.
Step 2: Inventory
Lilypad Arduino + Programmer and USB Cord
Two Coin Battery Holders with Two 3v Lithium Batteries
White on Blue 16x2 LCD Screen ( 5v )
Ultrasonic Rangefinder ( 2.5-5.5v )
Spool of Conductive Thread
Pair of Winter Gloves
Different Types and Colors of Fabric for "Flare"
Various Sizes of Needles for Sewing
Four AAA batteries
A battery pack for the batteries
Common copper wiring
Attached are some pictures of some of the hardware and materials needed.
These pictures were taken from the SparkFun website...sparkfun.com
All materials were purchased from sparkfun.com as well, aside from the gloves.
Step 3: Set Up the LCD
We also found that soldering the screens connections to the Lilypad helps a lot with connections. The stronger the connections, the better the LCD screen will work.
Step 4: Connections
LCD - Lilypad
Pin 1 - Ground
Pin 2 - Power
Pin 4 - Petal 11
Pin 6 - Petal 12
Pin 11 - Petal 5
Pin 12 - Petal 4
Pin 13 - Petal 3
Pin 14 - Petal 2
Range Finder - Lilypad
PW Pin - Petal 9
+5v - Power
GND - Ground
Step 5: Implement the Other Components
Attach the lilypad to the range finder using soldering materials, as well as the LCD screen connections. Ensure these connections are in the right spot using the connection numbers from step 3. If they are incorrect, you could cause catastrophic damage to the arduino. You could also cause multiple issues in the coding since it thinks certain connections exist while those connections dont actually exist.
Step 6: Set Up the Battery
Solder these leads to the lilypad, and place the entire setup (the lilypad/LCD/range finder setup) inside the glove. We found that putting the battery pack into the wrist section of the glove kept it out of the way while also keeping it easy to turn the glove on.
Step 7: Write the Code
If you want to learn the Arduino code further, here is a link to the Arduino Language Index:
Attached is the code that we used to program the Glove.
Step 8: Uploading the Code to the Arduino
The picture is taken from the internet, but is exactly the same as what you do to upload the code from your computer.
When you purchased the lilypad arduino kit, it came with an uploader, which is a USB cord, attached to an adapter, which plugs into the lilypad. To upload the code, very simply plug in this adapter between the lilypad and your computer, and click upload in the top left corner of you arduino software. Once the program indicates that it's complete, you're done :)
