The purpose of this project is to show, how you can build a surveillance system with web-page interface. The webcam can be moved vertical or horizontal through the interface, but only in the area that border sensors will allow. The control page is secured with login system, where the user types in an user-name and a password.
On the control page the user can control how the webcam will turn and how many steps it will run. The user can also turn the webcam on and off via web interface. Information about the states will immediately update on the screen. User can also turn the motion detector online, if the camera detects motion, it will automatically save the frames. Naming of the pictures is done with “timestamps”, so it is possible to find out when the picture was taken.
The part that interests me on this project is the servo, because a few years ago i was thinking to something like this, but i never build it. Now it’s nice to see, someone actually build it. Webcam With Servo And Web Interface:[Link] - [via]
This is my first AVR project. After going trough the tutorial i was telling you about a couple of days ago and after testing the “Blinky” project i decided to make my own Blinky. So i came up with this idea that the led’s should start lighting from the middle and move to the sides, when they reach the sides blink a couple of times and come back to the center.
I was actually quite easy to do it, i expected to be harder. I used the 8 LED board i designed in the avr butterfly starting guide.
Here is the LED’s in action:
Here is a zip archive containing both the source and the compiled hex. The code was written and compiled in AVR studio.
LCR meters used to be relegated only to professional design labs. Not any more. This portable LCR meter makes it easy for you to analyze the analog performance of virtually any device under test, whether in your lab or on the job. The dsPIC30F4012-based meter uses DDS techniques and DSP methods to condition the resulting voltage and current signals. Its handy user interface and graphic LCD make it easy to operate and read.
The project its cool and it is a great debugging tool for any electronics lab, but i still like more the commercial LCR tweezers.
The Electronic Mini-Badge is a PIC24FJ64GA004-based electronic badge that displays color slideshows. Many electronic badges display scrolling text using a matrix of discrete LEDs. This low-power system features a graphical OLED display and can be easily upgraded to handle animation, video, or RF communication.
I’ll have to take a look over this circuit’s schematic to see if i can easily adapt it to a Nokia 6100 LCD display, because i happen to have one, and it would be a nice project.
The dsPIC30F4012-based Doppler Radar System enables you to track speeding motorists in your neighborhood. The well-designed system generates a microwave energy burst with a 10-GHz transceiver. The microwave signal bounces off of a moving vehicle and the frequency (Doppler) shift is measured to determine its speed.
I must say this is the first DIY Radar system I’ve seen well documented. It’s definitely worth a try if you’re into this kind of projects.
