If you have an Etch a Sketch in the closet collecting dust, the Etch CNC may be an interesting project that could put it back into use. “I am using a retrofit machine that fit within my budget. It’s a 2-axis machine with approximately 170x130mm travel. The circuit board is my own design, using a ULN2803 per motor to supply approx. 0.3 amps per winding. The power supply is a
This Automated License Plate Recognition system makes short work of looking up massive numbers of license plates. I wonder if there is a system that will make the plate appear fine while looking at it but cause a mis-read when read in using the camera system? “Automated License Plate Recognition (ALPR) technology is made up of several elements. Platefinder – Sophisticated firmware continually searches the camera’s field of view
You might remember the article of the in progress 6 Axis PC Controller, well it is now complete. This thing is very impressive, doesn’t look like the standard weekend DIY because of the complexity. “My microcontroller doesn’t have built-in I2C or SPI, so I needed to implement one of my own. I also didn’t have interrupt pins available, meaning my solution needed to be based on polling. When all
Ok, now I know the first think I will buy after winning the lottery. I need one of these waterjet machines. I have seen them in operation from time to time on American Chopper but I didn’t realize that the machine is so versatile. I am thinking that one could easily make a very profitable business making things out of old circuit boards that would be destined for the landfill
Play the video to check out the cool effects of the VGA Expropriator. There are lots more videos and pictures in the creators site. “Video synthesis tends to be dominated by digital technology these days however analogue video synthesis techniques can still offer a great many advantages in terms of aesthetics, performance, simplicity, and adaptability. Not to mention the non-linear surprises which can come from working in the analogue
The ultrasonic sensor and computer software provide a convincing illusion of direct interaction. “Another installation exercise. Idea copied from another installation for ease. Ultrasonic range finder is used to detect distance of object form it and data is processed in flash, and displayed in form of grass. Same technique can apply to many other skin like running people (from the UFO… )”
Driving your Roomba around using your phone is so last month… Today the cool way to do it is by tilting your Apple MacBook. I wonder what Todd will come up with next? “This project shows you how to use the built-in tilt sensors of the MacBook to control a Roomba. Since Perl hasn’t been used to program a Roomba yet, it seemed like a fun task to show
