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
Looks like the DREAD could be a popular future weapon. “Imagine a gun with no recoil, no sound, no heat, no gunpowder, no visible firing signature (muzzle flash), and no stoppages or jams of any kind. Now imagine that this gun could fire .308 caliber and .50 caliber metal projectiles accurately at up to 8,000 fps (feet-per-second), featured an infinitely variable/programmable cyclic rate-of-fire (as high as 120,000 rounds-per-minute), and
Don’t know much about this, Targit posted a link to his creation in this Hackaday article (comment #16). If anyone knows about some construction plans I would be interested!
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 rubber band LEGO crossbow isn’t as dangerous as this one. But I wouldn’t want to be standing in front of it when it goes off!
Once you have a look at this EM Pistol, and watch the video you will probably want to get in line to buy your own! “# Two coils are precisely pulsed in sequence (350 Amp peak) to fire a steel projectile # Two infrared sensors detect the projectile position within the firing tube # Controlled by a PIC microcontroller # Powered by 8 AA NiCd battery pack # Built-in battery
