Handheld Replica of Portal Gun

If you’ve ever wanted to own the Aperture Science Portal Gun from Valve’s hit game Portal? It’s possible as this tutorial will show us what and how to make your own as close as the original image.

The gun not only looks exactly like the model, but has all sorts of added touches that give it that extra bit of believability, like multiple blue and orange LED lights that turn on and off when the gun is in different modes and sound effects, which are selectable from a control panel on the rear.

This replica even shoots a real laser and uses a motion sensor to belch smoke and play an audio track when someone is close by.
