Instructables

Make an electronic device in the street (IR Pen)

Sometimes you don't have enough materials and space to make any instructables so you keep reading them ...
I wanted to make some very simple instructables so anybody can do it anywhere. It won't be the most impressive instructable but may be the most basic in electronics.

This first hack can be done on the street without soldering iron or else.
Ok, I've done mine on the kitchen table and a bulky soldering iron is visible but you can definitely make it in your jungle, could be green or grey jungle. 

My motivation is a mix: my kids can try (9 and 4 years old) + I'm not equipped with good electronics anymore + I live in apartment + I prefer to invent something new than going to stores + it saves the planet and my purse too.

I needed IR pens for Wiimote whiteboard and wanted to used a dirty cheap "Wii sensor bar" ($3, in fact there are no sensors but IR leds, sensors are in the Wii remotes), it's the less expensive way I found to get 6 IR leds already soldered on a board.
I also wanted to use AA batteries that you can replace in your device.

The minimum you need for any this kind of cheap electronic device is:
- aluminum foil
- duct tape or any tape
- scissors
- an electronic device to hack, here a Wii bar
- screwdrivers to open your device
- wire cutters to cut your electronic board

The trick here is simply to use aluminum foil and tape to make: battery case + switch + holder for the electronic part.

Cut a piece of duct tape and roll it with adhesive outside the battery.
Usually duct tape width is the size of an AA battery. If it's not the case, simply cut your tape.

Keep it a little bit loose so you can change battery later.
This tape roll will be the holder of everything try to keep it sticky.
Welcome and congrats on posting your first Instructable!

I see that you wanted to show that electronic devices could be made in various places but since you walked us through how to make an IR Pen you might want to consider changing the title so that people don't get confused. Putting the IR pen as the main image may help too.

Thanks Sherry,
There are already so many IR pen projects and the point here is more about the survival way to make some electronic device from Mac Gyver's stuff.
That's why I've chosen the survival category. Actually just changing the IR led for another type of led still work in this project.
I understand your point but I've chosen this title on purpose, the way IS the mean ;-)
