It could be used for making beer also. It minds my brew using a usb port. It continuously monitors alcohol percentage by counting carbon dioxide bubbles and then back-calculating the amount of alcohol produced. On the PC side, a VB.net application to interrogates Teensy at a specified frequency and reports back the number of bubbles counted and converts volume of carbon dioxide produced to mass of ethanol produced.

Teensyduino - Add-on for Arduino IDE to use Teensy USB development board Teensyduino is a software add-on for the Arduino, to run sketches on the Teensy and Teensy++! Running Sketches on the Teensy Most programs written for Arduino work on Teensy. All of the standard Arduino functions (digitalWrite, pinMode, analogRead, etc) all work on Teensy. Teensy is not limited to only serial device type. All communication is performed at full native 12 Mbit/sec USB speed. Teensy has the same built-in peripherals as Arduio: analog inputs, SPI, I2C, PWM, and a real serial port. How Does Teensy 2.0 Compare With Arduino? On May 19, 2012, Arduino Leonardo was released, using the same ATMEGA32U4 chip as Teensy 2.0. Both Teensy 2.0 and Arduino Leonardo support USB Serial, Keyboard and Mouse.
About DorkbotPDX | DorkbotPDX DorkbotPDX is the Portland chapter of Dorkbot, people doing strange things with electricity. We were founded in 2006 are now in a permanent (revolutionary) process of redefining ourselves and the logistics of this organization. We are a community of creative types who enjoy experimenting, finding art in technology and pushing the limits of whatever is in front of us. We meet on an regular, informal basis every other week, but you can find out more on our meetings page. We occasionally hold larger events and workshops, so sign up for the mailing lists to find out what's going on. We welcome you to join us at our gatherings and to bring something interesting to view or ponder. Tiny portable AVR projects: Business card breakout boards For all of our different AVR microcontroller based projects, we seem to find ourselves continually wiring up minimalist target boards; little circuit boards that fit both the AVR and a 6-pin header for connecting to your in-system programmer. And, when you find yourself hand-wiring the same circuit over and over again on a protoboard, that’s really just life’s way of telling you “just lay out a damn printed circuit board already.” Coincidentally, we needed a new business card. That’s a bit of an exaggeration; we didn’t need a new card so much as we were enamored with the idea of having a card that did something interesting. We certainly aren’t the first to have that itch– people are already making interesting electronic or circuit business cards, and there was even a contest at Hack a Day to design circuits that would run on their business cards. (Digression complete.) Project goals We’ve been designing a lot of things based on the ATmega168, and we didn’t want to wire up any more by hand.
Arduino board as ATtiny programmer This tutorial shows you how to wire up an Arduino used as an ISP (programmer) to an ATtiny45 or ATtiny85. To find out how to write code for the microcontroller, see the the tutorial on programming an ATtiny using the Arduino 1.0.1 software (or the older version for Arduino 0022 ). Materials and Tools For this tutorial, you’ll need: Arduino Uno or Duemilanove (w/ an ATmega328, not an older board with an ATmega168) ATtiny45 or ATtiny85 (8-pin DIP package) a 10 uF capacitor (e.g. from Sparkfun or from Digi-Key ) a breadboard jumper wires For more information, see our list of materials and parts and our list of prototyping supplies . Download and Install the Arduino Software You’ll need the Arduino software (version 1.0.1 or 0022). Turning the Arduino board into a programmer We’re going to use the Arduino board to program the ATtiny. Run the Arduino development environment. Connecting the Arduino board and the ATtiny We’ll connect the Arduino board to the ATtiny as shown in the following diagram.
forum • View topic - Omnidirectional Remote Controlled Robot I just did a very quick and rough assembly... and well... it works kinda, the wheels without any plastidip or similar on a wooden floor slip and slide a ton and my tiny DC motors with not much down-gearing in the gearbox spin way too fast, the robot moves in the expected direction reasonably well, but it's basically spinning at least 4 times the distance is moves if that makes sense, and since it has 4 wheels with no suspension or give what so ever going over anything makes at least one wheel free-wheel in the air. And this is without the 300g battery, motor controller boards, arduino mega and second level on top, I expect the performance to get even worse with that weight on top. I'll need to find something like plasti-dip to coat the rollers with as well, clearly needs more traction. Quick sketch
Store This audio adaptor lets you easily add high quality 16 bit, 44.1 kHz sample rate (CD quality) audio to your projects with Teensy 3.0 or 3.1. It supports stereo headphone and stereo line-level output, and also stereo line-level input or mono microphone input. The Teensy Audio Library lets you use the input and output simultaneously together with a toolkit of audio processing objects, to easily create all types of sophisticated audio applications. You can play multiple sound files, create synthesized waveforms, apply effects, mix multiple streams and output high quality audio to the headphones or line out pins. Teensy 3.0 & 3.1 have the Cortex-M4 DSP instructions which provide plenty of computational power for real-time FFT (spectrum analysis), opening up the possibility of creating advanced sound-reactive projects. Two of these 14x1 pins can be used to easily soolder the Teensy 3.0/3.1 and audio board together. A 14 pin socket and 14 pin header can be used to make them plug together.
