My 4 years old son wanted a wand to play. First, I've decided to alter some wands available in Thingiverse and make room for the electronics.

It was a daunting task and didn't work as expected.
So, I've decided to create one from scratch with all the room needed for the electronics.

INSTRUCTIONS

What we need

• A 2mm LED (your choice of color)
• A push button (those that come with arduino kits)
• A 110mAh 3.7v lipo battery
• 2x 2.5x20mm screws to screw the bottom of the wand to the base.
• A XH2.54 2P male to connect the battery.

Just wire everything together like in the image and you're done.

Assembly

The assembly of the wand is easy:
Cut the legs of the LED almost to the end (see photos).
Wire the LED with two long 1mm wires - long enough to reach the end of the base.
Isolate one of the legs with thermal sleeve.
Force the LED inside the top.

Glue the top and the base with a strong plastic glue.
Wire the push button and insert it into the hole - put a dab of glue to hold it in place.

Wire the battery connector - ATTENTION TO THE POLARITY - and you're set.

Just put the battery inside the base (it will not fit all - the bottom has room for it to) and insert the screws.
