Woodworking Contest

Step 1: Materials Needed

For this project you will need three pieces of wood.
Dimentions:
- .75 x 1.5 x 2.25 in.
- .75 x .5 x 1.5 in.
- .75 x .75 x 4 in.
(If you already have these peices you can skip to step 6, if not i will show you how I cut them out from a peice of wood that is 1.5 x 1.5 x 24 )
(Try to get the a hard wood that doesn't split easily down the grain)

As for the actual tools, you will need:
- A ruler
- A pen
- C clamps (optional)
- A saw (hand held, table, or band saw)
- Grinding sticks and/or sandpaper (optional)
- A drill
- A wood 3/32 inch drill bit
- Screws that can be 1" or 1 1/4"
- Wood glue (optional)

Step 4:

Now get the 4 and 1.5 inch peices and draw a strait line separating the 4 inch peice in half ( .75 of an inch ) and draw a line on the 1.5 inch peice that is .5 inches away from the edge.

(The pen marks should be drrwan on the freashly cut surface or the one on the opposite side )

Then cut

Step 5: The Wooden Peices

Once you've cut them you have the 3 basic peices :)

Step 9: The Final Peices

PICTURE 1
Now that you have your final peices you can put them together and see them start to form the key turner.

PICTURE 2
Now we need to see were we are going to insert the screws

PICTURE 3
Draw a line down verticaly from the top peice onto the lower peice

Draw a line from where the bottom of the 4 inch peice of wood hits the 1.5 inch peice of wood

PICTURES 4 & 5
Follow the line around both peices of wood (Make sure the lines are straight)

PICTURE 6
This should make a recangle. Draw two diagonal lines from the corners. (This is ment to help you find where to place the screws)

Step 10:

PICTURES 1 & 2
Use a clamp to hold the big pieces together.

PICTURES 3, 4 & 5
Use a small drill bit to drill two holes into the wood (This prevents the wood from cracking and helps guide the screw into the wood)

PICTURES 6, 7 & 8
Repeat the last step for the other two peices that got together

(You can use only one nail and you can even use a suuuper strong glue)
(If the wood splits you can always glue it back together)

Step 11: Screw Time

Now insert the screws

(You can use only one screw if you want and you can even use a suuuper strong glue)

(If the wood splits you can always glue it back together)

Step 13: The Key Turner in Action

We have a be nice policy.
Please be positive and constructive.

Introduction: Wiimote Modification for Persons With Disabilities

This instructable will show you how to rewire the button of the Wiimote to bigger buttons so that persons with disabilities will be able to efficiently use the Wiimote by not having to press the small buttons on the Wiimote. The buttons that will be rewired will be the A button, B button, the directional pad (up, down, left, right), and the Home button.

Update:

An updated wireless version of the adapted Wii-mote using an Arduino board and Xbee wireless circuits can be found here.

Space Challenge

Step 1: Soldering Tips Before You Begin

To solder very small items follow the following procedure:
1. Spread some soldering flux on the components you wish to solder.
2. Gather a bit of solder on the tip of your iron.
3. Touch the components together.
4. Give the components a kiss with the soldering iron. The solder on the tip should transfer to the components.

Take care not to put to much solder on the tip of the iron, doing so may result in the bridging of two or more components you don't want soldered together

Step 2: Disassemble the Wiimote

Begin by removing the batteries. Remove the four triangular head screws. For best results use a triangular-end screwdriver. However the screws can be removed using a small enough miniature flathead screwdriver. Crack open the case with a miniature flathead screwdriver by releasing the pressure clip at the front part of the case. Take out the circuit board.

Step 3: Remove the Nintendo External Port

To begin secure the circuit board in a clamping base or on the edge of a table. The idea is to use the heat gun to heat the soldering points inside the red square shown and then yank out the port. The heat gun should be held close to, but not touching the circuit board. Aim the gun so that only the area within the red square gets hit with the hot air. Use pliers to grab the Nintendo External port as to not burn your hands. Make sure you have a good grip on the External port before you begin. Also remember to WEAR EYE PROTECTION. Depending on the strength of your heat gun it will take 30 seconds to a minute. Do not pull on the External Port until you visually see all of the target solder points liquefy. Once the solder points liquefy, removing the External port will require minimal effort. Once you successfully removed the External port let the circuit board cool for a couple of minutes.

Step 4: Drill Holes for the 8P8C Female Port

To mount the 8P8C Ethernet Female port onto the circuit board you will have to create three holes. Securely clamp the circuit board. Line up the 8P8C Female port with the circuit board so that the pegs of the Female port are close to the edge. Make two small guide hole in the circuit board using a hand drill. The center of the holes should coincide with the center of the plastic plugs of the 8P8C Female port when properly lined up. Increase the hole diameter incrementally until the holes fits the plugs. Test your holes by plugging in the 8P8C Female port.

Next make a third hole whose center coincide with the center of the rows of pins of the 8P8C. Increase the diameter of the hole until the two rows of the pins of the 8P8C could fit the hole without touching the sides of the circuit board. Then using a Dremel Rotary Tool grind the sides of the hole until all of the pins of the Ethernet Female port pins fit without touching the circuit board.

Step 5: Solder Wires Onto the 8P8C Female Port

Please wear safety glasses when soldering. To begin cut 8, 28AWG (or smaller) wires to about 8 inches in length (these will be cut down to a shorter length later). You can also use 28AWG ribbon cable as a substitute. Simply peel 8 wires from the ribbon cable, 8 inches long and you're good to go. In total 8 wires should be soldered to the 8P8C, one for every pin. Unsheathe the wire about 1/4 inch on both ends. Then solder one end of the wire to the 8P8C taking care not to bridge any pins on the 8P8C. (For tips on soldering see Soldering Tips section below.) Then use 1/16" heat shrink tubing to make sure that no short-circuiting occurs.

Step 6: Mount the 8P8C Female Port

Attach an Ethernet port to the circuit board with the wires coming through the hole towards the top of the circuit board. Make sure to put in the 8P8C on the bottom of the circuit board.

Step 7: Solder the Wires Onto the Circuit

To begin you must first designate what Wiimote button goes with which cable. The cable designation on the 8P8C. This table will be useful when making your External Connector Box.
8P8C
(Port Number) (Button )

1 A-Button
2 B-Button
3 Home
4 Up
5 Down
6 Left
7 Right
8 Ground

Please wear safety glasses when soldering. While keeping track of which wire you solder to which button in relation to the Ethernet port, solder all wires to the contacts indicated. It is important to solder to the correct side of the button contact. Cut the wires so that the wires run along the edges of the circuit board as far as possible. Extra wire will make it difficult to put the case back together, and could disable the buttons on the Wiimote. (For tips on soldering see Soldering Tips section below.)

Step 8: Grind the Case

The newly installed 8P8C port is larger than the original opening on the bottom piece of the Wiimote. In order to reassemble the Wiimote the opening must be made larger to accommodate the 8P8C port. Please wear safety glasses. Clamp the bottom piece of the case. Using the Dremel Rotary Tool slowly grind away the case's plastic until the circuit board lies completely flat against the case. Be sure not to grind the tab that holds the battery case in place. If you do grind the tab, simply superglue a thin piece of plastic in place of the tab. This should be sufficient to give the battery case something to grab onto.
Once the 8P8C fits in the Wiimote case where the circuit board is pushed in all the way, you will see that the battery case will not close. In order to fix this a small part of the 8P8C will have to be grinded with the Dremel Rotary Tool.

Step 9: Assemble the Wiimote

Finally the Wiimote is ready for assembly. To begin place the buttons in their original slots in the top case of the Wiimote. Then lower the circuit board in place while using miniature flat-head screwdriver to maneuver the wires. Depending on the diameter of your wires you will probably have to make a few modifications to the top of the case to make enough room for the wires. Once the circuit board is flush with the top case bring in the bottom case. Making all of the everything fit within the small space available on the Wiimote will require a lot of patience and finesse. But don't be discouraged, it is possible to fit everything within the Wiimote.
Once everything fits in place, tighten the triangular-head screws back on the case. Finally put in the batteries and try out your Wiimote. If your Wiimote doesn't work make sure to try it out with brand new batteries before disassembling it.

Step 10: Assemble the External Connection Box

To operate the modified Wiimote with external buttons you will need to create an External Connection Box. The external connection is box is simply a project box, available at any RadioShack, with and input 8P8C Female Connector and a number of output connectors for varies user devices. Only passive, normally open, pushbuttons can be used with the modified Wiimotes. However this type of button comes in a wide variety of forms featuring different connector types. You are going to have to customize your case based on pushbuttons available to you. For this Connection Box we use two individual pushbuttons with 3.5mm mono plugs, and a directional pad with a DE-9 Serial connector.

The insides of the Connection Box were wired so that the Blue and Yellow buttons, be the A and B buttons, the brown button, in Figure 20, be the Home button, and the directional pad be the Cross Buttons.

We have a be nice policy.
Please be positive and constructive.

Assistive technology is a generic term that describes tools used by people with disabilities to accomplish tasks.

The following technologies help people use computers to access the web:

Screen readers: Software used by blind or visually impaired people to read the content of the computer screen. Examples include JAWS for Windows, NVDA, or Voiceover for Mac.

Screen magnification software: Allow users to control the size of text and or graphics on the screen. Unlike using a zoom feature, these applications allow the user to have the ability to see the enlarged text in relation to the rest of the screen. This is done by emulating a handheld magnifier over the screen.

Text readers: Software used by people with various forms of learning disabilities that affect their ability to read text. This software will read text with a synthesized voice and may have a highlighter to emphasize the word being spoken. These applications do not read things such as menus or types of elements - they only read the text.

Speech input software: Provides people with difficulty in typing an alternate way to type text and also control the computer. Users can give the system some limited commands to perform mouse actions. Users can tell the system to click a link or a button or use a menu item. Examples would be Dragon Naturally Speaking for Windows or Mac. Please note both Windows and Mac have some speech recognition utilities, but they cannot be used to browse the web.

Alternative input devices: Some users may not be able to use a mouse or keyboard to work on a computer. These people can use various forms of devices, such as:

Head pointers: A stick or object mounted directly on the user's head that can be used to push keys on the keyboard. This device is used by individuals who have no use of their hands.

Motion tracking or eye tracking: This can include devices that watch a target or even the eyes of the user to interpret where the user wants to place the mouse pointer and moves it for the user.

Single switch entry devices: These kinds of devices can be used with other alternative input devices or by themselves. These are typically used with on-screen keyboards. The on-screen keyboard has a cursor move across the keys, and when the key the user wants is in focus, the user will click the switch. This can also work on a webpage: the cursor can move through the webpage, and if the user wants a to click on a link or button when that link or button is in focus, the user can activate the switch.
