I have built a few speaker enclosures over the years. Mostly sub boxes that are made from square cuts of MDF on the table saw. A bit of handy work with a jigsaw and a drill usually results in a speaker box that is functional but definitely doesn’t look as good as a store bought speaker cabinet. This DIY 2-Way Loudspeaker that Adam McCall built isn’t a budget build since
Koen has just completed his 8X8X8 LED Cube which is powered by an Arduino. This is a really impressive looking build! “I finished my latest project. I wanted to build a led cube. It had to be big (8x8x8) and easy to build! I found a way to do it! 32 meter of stainless steel, 128 meter of wire ,8 meters of heat shrink, 8 max7219 chips later. It all
Malte Ahlers from Germany sent in this great Microsoft Kinect controlled Delta Robot (translated to English). We have seen quite a few Kinect hacks recently but this one represents something that interfaces very well with an external device like we have seen in the past with quite a few Wiimote Hacks. “I built a delta robot and tried to control it with the Microsoft Kinect sensor. My aim was to
Annie (Wei) Dai from Cornell University sent in this Vowel Voice Decoder System she did for the ECE 4760 Class. “The audio input is sampled through a microphone/amplifier circuit and analyzed in real time using the Mega644 MCU. The user can record and analyze his/her speech using both hardware buttons and custom commands through PuTTY. In addition, the final product also supports a simple voice password system where the user
Our friend Robert Oschler is running a Kickstarter for his new Robodance 5 – Telepresence Robotics for the Disabled project. Check it out and support it if you can. “What you are funding is the Pro version, which has additional exciting features and also has benefits for the physically challenged. Â For the first time in history an affordable consumer EEG headset is being sold called the EPOC, an Emotiv Systems,
We saw a project earlier this month that worked like an Ambilight system but this open source Light-Pack USB Ambient Lighting System seems to have much better effects. And since it’s open source you can get all of the info you need to make your own. I can’t wait till there is a system that doesn’t requite a computer to process the image. “The software analyses the image on your
This Double Sided Microcontroller Controlled PCB Exposure Box uses a PIC 16f268 to time the exposure LEDs on for the entered exposure duration. You can select if you are doing a single sided or double sided board, then you set the exposure time you need. After this you just sit back and relax while your board is getting perfectly exposed. We have seen some exposure boxes before including this UV
