We have the technology (to quote The Six Million Dollar Man), but commercial tools for exploring, assisting, and augmenting our bodies really can approach a price tag of $6 million. Medical and assistive tech manufacturers must pay not just for R&D, but for expensive clinical trials, regulatory compliance, and liability — and doesn’t help with low pricing that these devices are typically paid for through insurance, rather than purchased directly. But many gadgets that restore people’s abilities or enable new “superpowers” are surprisingly easy to make, and for tiny fractions of the costs of off-the-shelf equivalents. MAKE 29, the “DIY Superhuman” issue, explains how.

Root Beer Pong Bot

By Bob Knetzger

Here’s a “noninvasive hack” that takes advantage of ReCon 6.0 Programmable Rover’s cool features while adding a fun new function to make a “Root Beer Pong Bot.” (Page 161)

Code Sheet

Rover-pong-code

Here’s the code sheet for the game program I wrote. Each numbered box is a step in ReCon’s instructions. ReCon beeps, announces the game and 10 points, turns around (so that he presents the cup to you), backs up, stops to announce 75 points, turns and backs up, turns and backs up again, stops and announces 50 points, turns and backs twice again, then if you haven’t yet gotten the ball in the cap and triggered the kill switch, Recon blows his horn and announces you lost, as he does a victory dance to a dance beat.

What kind of game program can you create? Can you use the LOOP command and HOME command to make a more elegant routine?

The weight of the ball trips the switch, cutting off power to the ReCon which stops in its tracks, and also illuminates the “kill” bulb. Your score is the last point amount ReCon announced. Remove the ball and play again. ReCon’s non–volatile memory keeps your program!

If you do open up and invasively hack a ReCon inside you’ll find a really cool module with twin geared motor drives, each with interrupt wheels and opto emitters/detectors for counting partial rotations.  What else could you make with this?
