Fresh hacks every day
For their senior ECE 4760 project, engineering students [Brian Harding and Cat Jubinski] put together a pretty impressive portable face recognition system called FaceAccess. The system relies on the eigenface method to help distinguish one user from another, a process that the pair carried out using MatLab.
They say that the system only needs to be hooked up to … Read the rest
[Frank] decided to augment his desk lamp’s features by adding dimming controls (translated). Since the light source is a triad of LEDs the best method of dimming their intensity is to use Pulse Width Modulation. That’s the method that he went with, and luckily the SUNNAN lamp from Ikea which he’s using as the donor for the project … Read the rest
[HuB's] set of 5.1 surround sound speakers was gobbling up a bunch of electricity when in standby as evidenced by the 50 Hz hum coming from the sub-woofer and the burning hot heat sink on the power supply. He wanted to add a way to automatically control the systems and offer the new feature of disconnecting the power from the … Read the rest
[Pritika] is a user experience design student who just finished up an autonomous blimp project designed to react to voices and communicate, “his friendliness and eagerness to be noticed.”
The instructable [Pritika] posted goes through the build – a 850mAh LiPo battery powers an Arduino Pro Mini, which controls two 3.6 gram servos. While not much in the way of … Read the rest
Quite often, we see project boxes that seem to be constructed more as an afterthought than anything else. That’s not to say there is anything wrong with stuffing your latest creation into a nondescript black box, or even cardboard if it happens to fit your needs. Sometimes however, an enclosure embodies the spirit of a project, making it all … Read the rest
Make: Projects has posted an interesting way to burn designs into wood. Instead of doing the traditional method of using a hot iron to hand draw or trace patterns on the wood, they show us how to use a chemical process to make things easier. They are using a solution of Ammonium Chloride, applied with a foam stamp, then … Read the rest
The Optigan and Orchestron were a pair of electronic organs built by Mattel in the 1970s which used swappable optical discs to store instrument information. The discs can still be found today, but the organs are extremely scarce, much to [Gan’s] dismay. After researching the organs for a bit, he decided he could probably build his own MIDI-compatible interface for … Read the rest
