Blog - 10 awesome things you can do today with iBeacons. 10 awesome things you can do today with iBeacons iBeacons have been getting a lot of press lately about how they are going to transform retail, but iBeacons are much more than that. You can use them for a bunch of cool stuff with your iPhone, your Mac, and a couple of iBeacons. First, a bit of background. iBeacons are Bluetooth devices that broadcast to your iPhone or iPad to let them know the beacons are nearby.
Here are 10 awesome things you can do right now using iBeacons. All of these work with any iBeacon, but they work great with our Bleu Station iBeacons. Here they are: Most of these tips make heavy use of Geohopper for iOS, since it is a great general purpose tool for making things happen when you are near an iBeacon. Geohopper for Mac is the sibling of Geohopper for iOS and, as the name states, runs on your Mac. Let’s get started. 1. Wouldn’t it be nice to have your Mac go to a locked screensaver whenever you leave your office space? Video 1 Video 2 2. 3. 4. 5. Get a webcam. 6. 7. SumoBotKit. Multiply the robotic arm and electronics | J-J Shortcut's Blog. Posted: August 17, 2010 in Electronic, Mechanical Since I build my robotic arm and the electronics, there has been some progress. 2 friends of mine are busy with the programming, the are making a program in JAVA to control the robotic arm. I have been busy with making more arms, a friend and I did go to a Fablab in utrecht.
There we made 8 robotic arms from hardboard 4mm on a lasercutter, it only took about 6 minutes to make one! Below a picture of the lasercutted arm: I really want a lasercutter now! :p its such a usefull and fast tool! But since we now all got our own robotic arm, we wanted to test it. The circuit has the following features: External feed option Power-on LED 3 switches or 3 LEDs IR receiver module plugin Controlling of 7 servo’s (6 steering signals) Analog read of the potentiometers of 6 servo’s 2 extra i/o pins With this shield we are able to control and read the servo’s and also use some switches and LEDs for a friendly interface.

This is a circuit whose light will turn on once it is exposed to darkness. So it's a light that will come on when it gets dark such as at night time. This is extremely useful for people who may live in a house that have vision problems and need the lights to automatically turn on when it gets dark. It's also very useful for elderly people who live in a home who may have difficulty walking to turn on lights when it becomes dark. In our circuit, we will turn on a lamp as soon as the level of light reaches a certain level of darkness.
Thus, the place where we place this circuit will always be illuminated, either by the natural light of the day or by the lamp of this circuit turning on when it becomes dark. Components Needed Photoresistor100KΩ Resistor2N3904 NPN TransistorLED2 AA batteries or DC Power Supply What we will use for this circuit is a photoresistor. Any type of LED can be used for this circuit. How to Build an Infrared (IR) Detector Circuit. In this project, we show how to build a simple infrared (IR) detector circuit. This is a circuit which can detect infrared light. To build an infrared detector circuit, we will need the following electronic components: Parts IR Phototransistor330Ω ResistorLED9-volt Battery Here you can find a wide variety of IR phototransistors at Jameco.
The circuit we will build from these parts is: IR Detector Circuit This circuit is very simple. When the IR phototransistor isn't exposed to any infrared light, there can be no current flow through the transistor, because infrared light is what produces base current in the transistor. When the transistor is exposed to infrared light, a base current is produced. And this is how the IR detector circuit works. Testing the Circuit Again, when testing this circuit, the sunlight will make this circuit work, since the sun emits infrared light, as do flames as well.
An infrared LED is an LED which emits infrared light. Related Resources. Raspberry Pi Plexiglass Case - WFFwiki. From WFFwiki Introduction I recently got my hands on the new Raspberry Pi single-board Linux computer, however it comes as a bare board with no case. I wanted to make a case for it which was both simple to construct and attractive to look at. Obviously you can jump over to ebay and buy one of the many laser/CNC cut cases available, but I like to remain in the spirit of the hacker community and make my own.
I recorded the whole build process as video, so you can simply watch the following video for details of how the case was made YouTube Video Design The case is made from a single sheet of plexiglass (acrylic) which is fairly easy to source from local hardware stores. The case is open-sided which makes construction very simple. To smooth the edges of the plexiglass (and give them a 'frosted' finish) I used a course file followed by a fine file to remove as much of the markings from cutting as possible.

DIY: Make a $3 Laser Diode Driver! Green Laser | Visible Laser | OSRAM Opto Semiconductors. 5 beginners projects that work in the first attempt | BUILD CIRCUIT. Just started electronics ? And you don’t know any engineering behind your projects and you are afraid of failure….then just read this article. Usually, success in initial projects plays important role in electronics amateurs and engineering students’ career.
Many students quit electronics because they fail in their first, second projects. After few failures, student keep a misconception that electronic projects working today might not work tomorrow. All the recommended projects have been tested by several students and most of them succeed in their first attempt. The 5 projects for beginners: a. Two years ago, I had published a video on youtube that shows all the steps required for making a dark sensor. WATCH THE VIDEOb. This is a very interesting circuit. You can see one more version of this wonderful project.
