Nikon Programmable Remote

Photographers always want to own a very high tech yet sharp lenses, as it enables them to catch those magnificent photographs. However, if you personal own an entry-level Nikon DSLR, you might be a little bit frustrated with the lack of certain features. In this case, it can be disappointing, as those self-claimed, “High-end” cameras are very expensive. If you’ve already bought the Nikon DSLR, don’t be too upset with it. We can still do something to overcome the downfalls. For your information, the cameras have an infrared sensor, where it can be utilized with great success using a remote control. With this feature, it allows you to take pictures and control your camera in a very far distance. We’re going to enhance the capabilities of the camera and makes it into the maximum with the help of programmable remote control! Basically, the project is based on a small remote control and an Atmel Atmega168/328 microcontroller as the main core. Beside that, it has a bunch of 3mm LEDs, capacitors, resistors, three switches, a battery holder and an IR LED.… Continue reading

The Magical TV Gadgets – Super TV-B-Gone!

Do you love to watch television programmes when you have free time? Are you a vivid fan of some of the famous television shows or series? Well, no matter you did or did not, as today you will have a closer look on this incredible Super TV-B-Gone gadget! Some of you here might have seemed this stuff before at other place, but for those that haven’t heard of it before, you should pay attention on this project, because it will need some high concentration here! With this Super TV-B-Gone, you can turn off TV from a very great distance. First and foremost, you will have to standby 48 IR LEDs and an Atmega8, as you’re going to apply these electronic components into this project! Also, please make sure that you’re buying the 860nm IR LED, as it will have 100 mW/sr, which it’s 70 mW/sr more than the 940nm IR LED at 50mA. Beside that, you have to arrange the LEDs in 4 rows of 12 pieces and the resistors fit quite nicely between the LEDs. You might also need… Continue reading

The Combination of Laser Modem with an Arduino Microcontroller

Can you ever imagine that what is the combination of laser modem and Arduino microcontroller looks like? Well, you might think that it will be a hard task and requires many complicated steps to get these two different components assembled, but it is easier than you’re thinking of… Let’s cut the long story short and get this project started right away… You’ll need to apply the serial data transition from an Arduino controller using a standard red laser, photo transistor and an instrumentation amplifier. Before that, please do make sure that you’ve ordered an IR LED and phototransistor pair from the local electronic store with some spare ATMega168 microcontrollers. After that, is time to start the first experiment by simply using the IR LED to transmit 2400 baud serial to the phototransistor. Therefore, you have to program the Arduino Diecimilia with the sample serial program, which it’s altering the baud rate and will allow it to run in a continuous loop! This is surely an interesting and challenging project, hope you all will enjoy it and having fun with it! Continue reading
