Progress Report No:2

Finally our studies are finished about the exact road plan about the project and it's components.

Considering the limited capabilties of the drscheme environment Ali is studying alternate ways to complete the project in case anything goes unexpected. That means we have an 'incomplete' backup plan.

Current assignments for the time being is as the following:
Aytaç: Manipulating world-bilgi.ss teachpack so that it can read inputs from the linux wiiremote driver.
Fırat: Connecting the Arduino board to drscheme in a linux environment.
Gökhan: Studying the architecture of the arduino board and doing the assembling work.
He did a damn good job about the IR-pens.

board marker to IR-pen

This is the second type of IR-pen that I made

CAUTION: Be careful while using soldering iron and hot wax gun. Accidentally touching the hot parts may cause serious burns.

-Find a board marker (you can steal one from your teachers :) ) and disassemble it. - Ready the parts that you will use: IR-led, a 22 ohm resistor, a button, a spring and some cable. - Cut the back of the board marker and put the cable soldered spring from the back. You may prefer to not to cut the back and put the spring from the front but its a bit difficult.

-Use some hot wax to fix the back end and the spring.- Mount the button on the body of board marker. You can use the soldering iron to melt the body but it will smell bad. If you use soldering iron to melt the body, don't forget to clean the tip of soldering iron. Also solder the resistor to any leg of the IR-led. (I prefered "+")


-Solder the cable from the spring to button. Also solder a small metal string(i used the part that i cut from the IR led) to the other leg of the button.

-Insert the IR-led and the resistor trom the tip of the board marker. Leave one leg of the IR led out. Use some glue and conductor foil(I used cigarette paper but aluminium foil is more suitable) to wrap the leg that you left out.

-Re-assemble your board marker. You may also want to use some insulation tape for the make-up.

How to make a simple IR-pen

We needed a few IR-pens to use with wiimote. So after a few reading I made some samples.

If you don't want to work with a soldering iron and a hot wax gun, you can always use a simple lighter with a LED lamp instead of an IR pen. If you prefer this just change the LED with an IR diode.

CAUTION: Be careful while using soldering iron and hot wax gun. Accidentally touching the hot parts may cause serious burns.

-Buy a simple flash light and dismount it.












-Use soldering iron to heat the metal part of the lamp and detach the glass part from the metal part.




















-Mount the IR-led to the place where you detached the glass part and solder it. Be careful about the poles of the IR-led. In standard leds, long leg is connected to the anode(+) of the battery.














-Cut the parts that you don't need. need.












-Just re-assemble it and your first IR-pen is ready.




Note that most of the flash lights use switches. If possible change the switch with a button.
