If you have something that needs to be turned on and off why not do it in a unique way. This Sound-Activated Outlet project lets us use an Arduino to monitor for sound patterns and then control an outlet accordingly. “The circuit for this project can be divided into two main parts: A microphone assembly and a relay driver. The microphone assembly is composed of an electret microphone element, two
Darbin Orvar built a cool tech electronic Christmas Tree. Best of all the above video will show you how to make your own. For more inspiration you can have a look at her blog. “My version of a DIY Christmas Tree made with redwood and plywood. Perfect for an apartment and easy to move around. As a bonus this tree is powered by an Arduino and LED strip lights playing
If your computer keyboard looks a bit plain why not kick it up a notch? NeIdan built this Airship Captain MK-I – Steampunk Keyboard that was built around an every day keyboard and by spending a bit of time and a few extra pieces you get an amazing data entry device. “Tools used: scissors and x-acto knives also used heavy duty cutter for cutting the plastic keys screwdrivers Materials:
Peter Marchant is going to have a wonderful Christmas with this MIDI Christmas Tree. As you play notes on the MIDI keyboard the tree lights in a cool pattern. “Using an Arduino and a SparkFun MIDI Shield to control Christmas Lights with a MIDI keyboard. The lights cycle colour (green, red, blue, orange) for each note or chord. Improvisation based on the minor blues scale on D.”
This Reverse Geocache called the Captain Herrmano’s Mystery Box packs a ton of sensors into the box and some slick programming brings it to like with a full on treasure hunt. “The housing – that is, the box itself – came from a Nanu Nana store (which is a German chain of stores). Inside of the housing, an Arduino Mega controls and receives information from different sensors and boards
 The prize this week is a wireless transmitter for your next project. This contest will run for one week (Dec 21 – Dec 26, 2014). Ending time is based on central standard time. To enter, identify the item above and what it can be used for. Don’t need a make or model, just what what the thing is used for. Please do not give the answer in the
If you have a bunch of boards to program and test you have probably thought to automate some of the steps. Wiring all the connectors, hooking it up to a computer, programming in test firmware, running the system through a battery of tests and finally programming in the release firmware can be a tedious task. snifikino shows us how he made a test jig that is connected to a
