Making a Twittering laser tripwire with webcam capture is quite easy. If you want to know how to make a laser trip wire that is capable of twittering and capturing an image from a webcam, you can use an instructable from instructables.com. This instructable will also show you how to create a laser tripwire that can execute any bash script command that you want it to any time you want it to. You do not have to be a pro to understand and use this instructable. Beginners will find it easy to use the instructable to create Twittering Laser Tripwire with Webcam Capture.

For you to create this kind of tripwire, you will need a GNU/Linux or Mac operating system that supports that has a Processing IDE and Arduino IDE that is fully functional. Windows OS that has a more complex processing application can also be used for the purpose of creating a Twittering Laser Tripwire with Webcam Capture. The hardware that you would require include an arduino board, a Laser pen or pointer, a resistor that is light dependent and another 100Kohm resistor. You can also get a Webcam and a breadboard though these are not important. The software that you need include arduino IDE, Processing IDE, Curl, Linux OS and Webcam. You will also need a mirror, soldering iron, hot glue gun a wire, a ball point pen and a hacksaw or a knife.

Have you ever thought of a portable arduino environment that you can carry with you anywhere you go, and still rely on it to tell you the time? Makerbot has come up with an amazing piece of technology that is a makerbot watch. The watch has got 12 LEDs which are used to mark the hours. It also features an LED at each of the 12 five minute points. There are four minutes that are excluded, but there are other four LEDs included in the Makerbot watch. The LCD will light up to show what time it is.

The Makerbot watch has an amazing array of specs that make it possible for it to work. For instance, it has an atmega328 chip that contains an Arduino bootloader. The header used for bootloading has 6 pins, as is the case with the header used for programming. The bootloading header has 4 I/O pins, power as well as ground. Other features include a 16 MHz crystal and a Piezzo buzzer to alert you of the time. The watch also has switches that work with three pushbuttons. There is another header that has 4 extensions and it is used as a plug in for shields, sensors and other things that are necessary for the watch to work.

Probably you still remember the times when TV games were popular. Now most of these games including Tetris, Snake can be found on most mobile devices. But if you want to play the magain on TV screen, then it’s time to make a simple console based on Atmega168 microcontroller.

Whole simplicity is that circuit is very easy to build it uses very few components couple resistors and push-buttons for control. Here is a video how this thing works:

This is really easy to build project which uses couple external components, Arduino and an old photo frame. All you need is to store 720 pictures with actual time words – for each minute in 12- hour cycle and then let the circuit to hit next button every minute.

First of all in order to hit next button you don’t have to build some kind of mechanical actuator – simple optocoupler will work fine. And probably the hardest thing is to think of generating 720 images with different words on it. No problem with that – a processing script can do this for you – just select right parameters and run script. After images are generated – upload to photo frame memory and start a clock. Someone wants to change frames every second – that’s only a 43200 frames to generate
