Control cyborg technology and revolutionize your PowerPoint presentations - build a wearable mouse!
So you converted some video glasses to a heads-up display glass. You built a wearable Raspberry Pi, pcDuino, or BeagleBone Black. Now, how do you control your cybernetic augmentations? You make a wearable mouse, of course!
The Point Shooter turns your hand into a mouse. Draw your gun gesture to activate, aim your hand to move the cursor, and pull the trigger to click. BANG!
The Point Shooter doesn't need drivers, is easy to build, and uses about $40 worth of common hardware-hacker staples you might already have. It's seriously badass and surprisingly usable.
Step 1: Equip Yourself!
Parts and Supplies:
- 1 Teensy 3.0
- 1 Wii Nunchuk
- 1 strip Swiss machined headers (female)
- 1 strip Swiss machined pins (male)
- 1 phenolic Veroboard, at least 4"x6"
- 1 Altoids Tiny Tin, any flavor
- 2 4.7kΩ resistors
- 2 ordinary tactile switches (pushbuttons)
- 1 12mm tactile switch.
- 2 Velcro cable ties, plus more to fit
- 2" of 0.5"-diameter heatshrink
- 2" of 1.5"-diameter heatshrink
- 10ft 26 AWG wire. Stranded is better, but solid works fine.
- 1 Micro-USB cable, 5' or longer
- Hot glue gun with sticks
- Soldering iron with solder
- Optional: Primer, paint
- You could try a knockoff Wii Nunchuk, but size is important here and it may not fit.
- You can substitute an ordinary button for the 12mm button, but your mouse will be harder to use.
- Don't substitute standard headers for the Swiss machined ones. The board won't fit in the case!
- If you can't find 1.5" heatshrink, electrical tape will work but the finished project will be sloppier. Harbor Freight sells it as part of a set.
- Tri-wing screwdriver
- Flush-cut pliers
- Dremel with drills, cutoff wheel, flapwheel, sanding drum
- Heat gun
- Needle file set
If the Altoids tin still contains Altoids, this would be a perfect time to eat them.
