The LM35 Temperature Sensor is a versatile and inexpensive sensor that could be useful in many projects such as a PWM Fan Controller or this LCD Thermometer project. In this case a ATMega8 reads the analog value and updates the LCD to show the current temperature. The code is provided so you can build from this example. “In the circuit the LM35 is connected to the ADC port of the
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
Chris from Pyroelectro demonstrates some Animatronic Mouth concepts to bring your next robot to life. I would like to have this animatronic face tied to my computer and raise an eyebrow when I have an email and raise both when there are more than 10 unread emails. 🙂 ” In this tutorial I will show you two simple methods for building a believable robotic mouth. One articulated and moveable, the
We have seen Plasma Speakers here before. They won’t replace your everyday speakers but they are sure cool. What’s better than reading about an interesting project? Building it! Instead of scrounging all the parts for a project a kit makes things real easy to duplicate and that is exactly what this is about. Matthew Chapman and Marshall Meng of Student RND have put together a Plasma Speaker Kit Kickstarter which
Halloween is right around the corner. If you are looking for something that can be whipped together quickly and scare the pants off the kids that will be terrorizing the streets, look no further than these DIY Halloween LED Blinking Eyes by Pete Mills. The microcontroller code is available here. “I connected the LED pairs to an ATtiny2313 microcontroller via some comms wire and some 2n3904 transistors for each pair.
