Philo has developed a new NTX LEGO sensor that is worth taking a look at. “I built this proof of concept of a light barrier using NXT light sensor and an optic fiber. Any small object passing between the end of the fiber and light sensor phototransistor can be easily detected, even if they have different color or reflectivity. The fiber I used comes from the RIS 2.0 kit, but
Nuxie1 did a great job on this PIC based USB project board. I am very impressed by the Eagle 3D plugin that was used to create the image above. “This design uses the Microchip PIC 18F2450 or 18F2550 USB enabled microcontroller. The total parts cost is around $15 including the microcontroller for a single board. The board features a USB port that can be used with a bootloader for easy
If you have some holiday money burning a hole in your pocket Dynomighty has just the thing. I have never seen like it before! “The incredible strength of these permanent magnets must be seen to be believed. Their force is so strong that under normal use the jewelry will stay on during normal daily activity. However, common sense rules apply; do not wear your jewelry under extreme conditions such
Check out this cool pen, I know it’s for kids but there is some serious technology in there! You can get your own here. “Pretty fly for an educational toy! The Fly Pentop Computer is the wave of the future–today. So…what is it? It’s an electronic pen with a brain (a built-in computer processor) and a recorded voice. Tweens (the targeted market) use a fat pen with a tiny
Check out this disco ball, it is powered by a CD player motor. Similar to this one, but spins by itself. “Here is my version of the LED Disco Ball. Its Completely portable can either be hung or screwed to the roof. It runs on 3AA batteries and has a group of gears from a CD player laser. Parts List: -3AAs -Metal Fujicolor Negative Film Control Strips Container -2 UV
If you are ever thinking about making your own voice recognition system, this project would make a great starting point. ” Firstly, we looked at the speech recognition algorithm to understand the implementation. We then prepared the microphone circuit, and then proceeded to start sampling and generate the digital data for the speech. Once we have the data, we started writing the code based on Tor’s speech recognition algorithm. We
If you have a BMW I would suggest getting a good alarm system. Have a look at the video to see why. Companies like Zieh Fix are keeping car manufacturers on their toes. Via: NewLaunches and Suprcars
