Tutorial: Arduino and Push-wheel switches - Birds on the Wire. Welcome back fellow arduidans! In this article we go back to the past via the use of push-wheel/thumb-wheel switches with out Arduino systems. Here are some examples sourced from somewhere on eBay: For the uninitiated, each switch is one vertical segment and they can be connected together to form various sizes. You can use the buttons to select from digits zero through to nine. There are alternatives available that have a wheel you can move with your thumb instead of the increase/decrease buttons. The switch’s value is made available via binary-coded decimal. We have common on the left, then contacts for 1, 2, 4 and 8. By now you should realise that it would be easy to read the value of a switch – and you’re right, it is. From a hardware perspective, we need to take into account one more thing – the push-wheel switch behaves electrically like four normally-open push buttons.

Example 40.1 The function readSwitch() is the key. So there you have it. Remote-controlled fiber-optic Ceiling Light with Arduino. , who wants to partecipate to our iniziative “ ”, sent us his new application with Arduino to demonstrate his skills in this field: a . Mauro decribes himself: The idea was to built a ceiling lamp that lights with a little surprise: a starry sky in my living room, even in the dark nights. To achieve my goal I used a wood table with many holes with different diameters that house the optical fibers. The size of the ceiling lamp (90 cmx 60 cm) did not allow me to use a single bundle of fibers and this is the reason of the two beams I used, each of which comes with a LEDs illuminator as shown: Each element is made with four LEDs connected in common anode way as shown in the figure: The schematic with Arduino and its control circuit is shown in the figure above: it is a very simple circuit that I built on a breadboard.

The transistor connected to the white LEDs is connected to pin 10 of Arduino, the TIP122 of the red LEDs to pin 9, the green LEDs to pin 6, that of the blue LEDs to pin 5. DIY Stroboscope using a Three Phase DC Motor - Hacked Gadgets - DIY Tech Blog. We have seen some Stroboscopes in operation before, for this DIY Stroboscope that uses a Three Phase DC Motor which eLabs put together I think the actual stroboscope is the simpler part of the build.

Since the project is using a three phase motor actually getting the motor to run is in my mind a huge part of the project. I love the reuse of computer related stuff in this build which is great since most of us normally have that stuff available for free! The code and schematics are available at the links below. Part 1 of the Project Build Part 2 of the Project Build Part 3 of the Project Build “With three driver inputs it is possible to create only two levels at the ends of the windings: LOW and HIGH. Using three different levels – LOW, HIGH and OPEN could have enabled us to disable one of the windings on each of the steps, which results in more torque and also enables rotational speed feedback via measuring voltage induced on the disabled winding by the permanent magnet of the rotor”

Focus stacking assistant for EOS cameras. Focus Stacking Assistant [EDIT] Here is a build log of mini-variant of this device. [/EDIT] One of my favorite shooting techniques is focus stacking. Many pictures on Circuits@Home site are made using this technique. I use Helicon Focus for post processing and even though this program has camera control built-in, it obviously requires a computer close to the object of shooting. Finished circuit can be seen on the title picture. The controller can also be set to “free run” mode. A single LED shows states of the controller. Even while connected to the camera, Focus Stacking Assistant allows camera buttons to function as usual. The control software is hosted on gitHub. The code has been extensively tested with Canon 5D Mark II and XSi cameras, it should work with any Canon DSLR with LiveView function.

We hope you are as excited about revolutionizing the bike light industry as we are. With your help, we will morph the Revolights bike lighting system into an innovative solution used worldwide. We recognize these lights are different, but we're from the Bay Area where different is, well, sometimes better. People aren't used to wheel mounted lights, but simply put, we intend to change that. Today we have a product (patent pending); a product we're proud of and believe in, but it's not complete!

Our goal here on kickstarter is clear... we must further the revolution; the bike lighting revolution. What is the Revolights bike lighting system? (Battery holding device and battery are not pictured, but they will be located on the hub. Where's development at? What's the money for? How long are we thinking this will take? A bit about why we are doing this, and why we believe...

Let's use a few stats to paint a picture… In 2008 [1]: Using an LED cube as an audio visualizer.

Arduino user projects How Did I Improve My Central Heating Control with Arduino? - Before I started this project, my central heating was controlled with Danfoss TP7000 room thermostat only by switching heating pump ON-OFF. Then I heard about Arduino, get interested, and decided to make an advanced control system for central heating: weather compensated heating controller, room thermostat, web-based remote control for the whole system, and web logging. Here's the result...
