The company which [Eric Wright] works for recently bought a Nintendo VS. It had Ice Climber installed as one of the titles but they asked the vendor if it was possible to swap it out for the Duck Hunt ROM. They had the ROM but not a light gun that would work with the system. [Eric] suggested they buy it with Duck Hunt and hack an NES Zapper to work with the VS cabinet.
Let’s take a step back for a moment. The Nintendo VS was a coin-operated gaming cabinet you would find in an Arcade. Luckily there’s quite a bit of information about the original hardware on the web. Some research helped him discover that electronically the only difference between the arcade and home versions of the Zapper is that the sensor capture is inverted. This was fixed by replacing a transistor in the gun with a jumper wire. The next challenge was figuring out how to wire the gun up to the second controller port. And finally he patched the ROM to work with the incorrect PPU as the right chip was not easily sourced.

Here’s another project that reminds us of the shooting games at a carnival. This was actually inspired by the video game Duck Hunt, and was undertaken as a class project between four students at San Jose State University. It uses moving glass targets that look like rubber duckies. The player shoot sensors at their base with a laser-tipped gun. A direct hit is indicated by the duck glowing blue.
[Lananh Nguyen] is a Business Marketing major, but he’s also minoring in Studio Art and has been blowing glass for years. We think he’ll always have a side job making and selling glass because those ducks look fantastic. [Michael] and [Chris] worked together, building out the oscillating platform which moves the targets back and forth, as well as wiring up light sensors to the Arduino. A green laser diode was added to an acrylic gun to complete the project. Check out the game play video after the break to see how it all comes together.
If you missed the other laser shooting range when we featured it last week, you’ll want to revisit that project which uses tin cans as targets.
