Arduino Nerf sentry gun build: Soldering the relay
The next step in making my autonomous Arduino Nerf sentry gun is to move the relay circuit from the temporary breadboard onto something more permanent.

Arduino Nerf sentry gun build: Relay firing circuit
I’m building an Arduino Nerf sentry gun. In the previous post, I showed how I wired and mounted the trigger connector. Next, I needed a circuit to fire the gun from the Arduino microcontroller. To me, the most straightforward way to do this is with a small, 5V relay wired to a digital pin and ground of the Arduino.
Collin’s Lab: DIY iPad Stylus
Fingertip input is great for most touchscreen usage like typing, web-browsing – all sorts of virtual button-pushing tasks. But for many people, drawing remains an activity best approached with a pen, pencil, brush, etc. With a bit of conductive foam and wire, it’s surprisingly easy to make your own conductive stylus, suitable for use with […]
Arduino Nerf sentry gun build: wiring the trigger
I’m building an Arduino-controlled Nerf sentry gun. Rather than build it and present the finished project all at once, I decided to chronicle the build here on Make: Online. The first step was to add wiring and a two-wire connector to control the trigger circuit. I opened up the Nerf Vulcan (about 30 screws) and soldered an 1/8″ female jack to the fire selection mode switch.

Every useful circuit board deserves a good enclosure. Providing a proper case for your circuit can protect it from accidental spills & falls – plus give it a cool look you can proudly show off even to those unfamiliar with soldering and such.

Homemade scuba-BORG costume in ‘Trek Nation’ documentary trailer
I’m going to see this Rod Roddenberry ‘Trek Nation’ documentary the moment it comes out. I’m hoping the maker of the scuba BORG costume reads MAKE and can post some more photos and what went in to it, love it.
Dust hood-to-lathe adaptation
Gary is a friend of a friend of mine. He is a master of building high-quality solutions to problems in his shop. Just watch how he adapts a dust hood to his lathe. The notched stick he crafts for adjusting the hood angle is a thing of beauty.
