You love to shoot all the marvelous photographs, especially the insects in flight motion. However, the ordinary digital camera doesn’t allow you to do so. Thus, you’re a little bit upset about it?
Well, it’s time to sweep all the frustration away! With this incredible setup for insects in flight, you can take pictures of insects in flight as easy as ABC. This unit is works on reflected laserlight, so it doesn’t require any laserbeam, or long arms to put the receivers on the top of the system. The full distance is now free between camera and insects.
The units can work perfectly, either in full dark or even in full bright sun! You can adjust the lens sensitivity by mean of a simple potmeter. In order to work in full dark, 2 to 4 extra high power LEDs are added. Two of these high power LEDs are UV LEDs at 405nm. For your information, this UV light can be used to attract some insects in flight.
Beside that, an optical extra lens system is added to look for insects in focus. With this extra system, you’re only need 40 usec to check if there are objects in focus!
If you born in 70s and 80s, you’ll probably one of those Tetris game players that spent a big portion of time everyday, just to create the highest game record and conquer the game.
Do you know that Tetris is actually a puzzle video game, which it’s designed and programmed by Alexey Pajitnov in June 1985? The Tetris name is derived from the Greek numerical prefix “tetra-” and tennis, Pajitnov’s favorite sport!
Instead of playing the Tetris alone, this parallel Tetris can double up the fun! This idea is to have each player playing the game on his own screen, by simply using the PS/2 keyboard for input. The interest part about this parallel Tetris, when one of the players has cleared his/her lines on the game, his/her opponent would go up a predefined number of lines in the game!
In order to add the fun of this game, you need to use two Altera De2 Boards, where these two boards can be used to communicate over the serial port. The main objective of this project is to do a project that had a visual components and how to utilize a variety of the resource offered by the DE2 Board.
When you’re doing this project, you’ll find out that it has a lot of fun and you can also learn many new C code for the NIOS and the VGA controller logic as well!
If you want to have a stylish and deluxe Arduino that compatible with the open source, you’ve came to the right place. The project that we’re going to discuss here is about the Illuminato – the elegant and able-bodied open source gadget.
This Illuminato using the ATMega645, where it has twice the code space and much faster code download speed than other ATmegas. The main purpose of this project is to keep the Arduino in shape and in the same time, it can allow to work with the TouchShield Slide, Stealth and other shields without any further medications.
If you refer to the above figurine, you can see a row of gold-lined aerodynamic holes up at the front of the board server. It has two functions, which as:
- It can reduce drag when the board flies over 200 mph.
- They also double as in-circuit programming pins, so that you can program the Atmel chip with the initial bootloader.
Beside that, it also has 42 I/O pins in a configuration, where it can accept any shield that was made for the Arduino’s pin header arrangement. The best part about this Illuminato is it 100% open source and GNU GPL’d as well!
You’re always wanted to build a RDS decoder, but you’re afraid that it won’t work for you here? Well, you don’t have to worry about it, as you’ll have the chance to develop a RDS decoder today!
RDS is the short acronym for “Radio Data System” or RDS is a communication protocol standard from the European Broadcasting Union for sending small amounts of digital information using conventional FM radio broadcasts. The use of more and more frequencies for radio programmes in the VHF/FM range made it increasingly difficult to tune a conventional radio to a desired programme. This kind of difficulty is being solved with the Radio Data System (RDS) that has been on the market since 1987.
Whether you believe it or not, the RDS has by now conquered all receiver price classes and is nowadays a must in the standard functionality of any radio receiver!
Basically, today’s project is a very simple RDS decoder that based on TDA7330B RDS demodulator and AT90S2313 controller. The RDS data is being displayed on a 2×16 character LCD. It will show program service name, RDS clock, TA flag status and scrolling 64 characters long radio text. The decoder needs a Stereo multiplex signal to act as input, where it’s normally found at the input pint of a Stereo decoder IC in many radios.
