“Diamond plate” industrial fixture plates on the cheap
My favorite laser-cutter is offering these switch/outlet covers in faux-aluminum diamond plate acrylic. $4 for a single, $6 for a double. [Thanks, Angus!]
DIY Projects
Arduino Nerf sentry gun build: Primary Arduino enclosure
For the primary Arduino enclosure, I started with a cast aluminum project box. It has a few holes in it from a previous project, but that’s alright, consider it ventilation. I marked and drilled holes for screwing the Arduino in place, as well as three large holes on the side for wiring, USB access and power plug access.
Train whistle doorbell
MAKE subscriber Pete Mills of Plymouth, MI wrote in with this excellent project: a Lunkenheimer steam engine train whistle pressed into service as a doorbell. (H)ave you ever missed the doorbell ringing? Perhaps you were in the shower or vacuuming the floor. Well, fear no more; you won’t miss hearing this one. I was given […]
MAKE class at Parsons produces awesome DIY projects
This semester at Parsons the New School for Design, I had the pleasure of teaching a group of inspired students (both undergrad and graduate) about DIY projects online. The students were interested in everything from electronics to crafts, and their final projects are tutorials across a very wide spectrum of topics. Here are the project […]
Sweet function generator build
After checking out the last installment of our Circuit Skills series, Mark Warwick went to work building his own take on the function generator project using a Pelican case + a custom laser-etched front panel. As you can see, the results are quite awesome! Additional infos after the jump – I’ve had quite a bit […]
Arduino Nerf sentry gun build: Making the stand
I designed a stand to support the gun and the distance sensor, Arduinos, and firing circuit. Using some 20mm >80/20 t-slot aluminum and connectors, I built this. It’s not really a tripod, but it started out that way, so that’s what I’m calling it.
Musical table plays melodies with Arduino
Haeyoung Kim made a “musical table” with two Arduino boards and a very interesting switch design (using conductive tape) on the bottoms of several interchangeable toys that play along the top. She provides source code, schematics, and the rest of the how-to over at Instructables. Here’s a little iPhone video of the project:
