Make: Online : Collin's Lab: Infrared heart sensor

After checking out a few projects involving IR heart monitors, I decided to have a go at the interface myself. Seen above are the results of my first experimentation with pulse oximetry. Getting the setup up and running satisfactorily required a bit more time and tinkering than I'd expected - especially after reversing a premature mod to my emitter/detector pair. The next version I try will either use a higher output emitter (see Charles Martin's version) or some amplification hardware (as used in Meng Li's sensor).

Bako.ca | Biking in place through Google StreetView

More usefully described, this project uses a head-mounted-display that has sensors for detection of orientation so that the user can be placed into a Google StreetView scene and can look around freely. For movement through the map, an exercise bike used to estimate forward movement using a simple reed switch that counts the number of revolutions of the wheel.
Pragmatically explained, it means that I don't have to sit in the darkness or stare at my garage door while I'm huffing away. Hopefully once this is done, I'll be able to spend a few nights a week pedalling away downstairs and work my way across the US or Australia over the course of the year. The irony of this project is, well, while it's supposed to help me entain myself while using the exercise bike, the project itself has been keeping me from exercising. Oh well.
It is also a project that I would be thrilled if someone took the idea and made a decent implementation out of it. Make it user focused and reliable and I'll be the first to use it.

DIY Apple Remote Shield for the Arduino

Have you ever wanted to make an apple remote? Or maybe want to have one of your arduino creations be able to control iTunes on your Mac, your iPod, Or your Apple TV? Now you can! 

Awhile back I was working on a project that that I wanted to be able to start music the on my mac through the IR receiver. After a while of looking around I found this library  which allows you to use your arduino as an Apple Remote. I integrated it in to my project and it worked great! So the other day I decided to make an Apple Remote shield for my arduino.

How to build an Air Guitar with Arduino, aka the AIRduino Guitar

The idea here is to build a wearable virtual guitar that is to be controlled with two hands much like playing Air Guitar. It has been created and prototyped during a two weeks project at ChalmersUniversity (Sweden) for a Physical Computing class.

The aim is to get the feeling of playing a real guitar. The AIRduino Guitar is made of one glove and one stick. The glove is used to set the tone and the stick to trigger the sound.

To perform such trick, we used an accelerometer and an ultra-sonic sensor (see Step 1 for concept description).

Take a look at the video demo to get a more precise idea of how it works, and get to work to build your own!

Secret Knock Detecting Door Lock - Made by Steve Hoefer

ow many times have you seen a secret hideout with a secret knock?  It's a staple of cheesy dramas, Saturday afternoon movies, and tree houses throughout the world.

While working on another project I ran across the Arduino knock sensor tutorial.  Sensing a single knock is a great little project for learning about microcontrollers, but what about sensing specific knocks?  Seeeeecret knocks?  And if we could detect a secret knock, shouldn't it unlock a door?   If you can't tell by looking this was cobbled together from spare stuff around the lab, it's not much more than a piezo speaker, a tiny gear reduction motor, and an Arduino. And PVC pipe.  How about a video to explain:

Charlieplexed row of LED lights, for the Arduino

This is my instructable on charlieplexing a LED row/string with the arduino. I noticed that there weren't many instructables on charlieplexing using an arduino, so i made this. I tried to keep the project simple, but that didn't work very well. The soldering is complex, I wouldn't recommend this as a first time soldering project.

$10 Arduino Beatbox (remake of the $5 Picaxe Beatbox)

"This is a simple sequencer machine which uses Capacitative Sensing Code for input to the Arduino. It is is a combination drumpad and sequencer. It has just two modes, record, and playback, and needs very few components; an Arduino (of course), and just 3 resistors and a piezo speaker. If you're feeling decadent, you can add an LED (with a resistor) for more "ooomph"."

Arduino noise box synth | mechomaniac

As my first Arduino project, it was a bit of an experiment with the Arduino programming environment, and I also wanted to investigate direct Audio synthesis using PWM on the Arduino. The basic sequencer concept came from the Arduino Punk Console, while synthesis was adapted from the Atmega SID Project.

The basic features are:

* 16-step programable sequencer with adjustable frequency and duration for each step
* synthesizer with 4 output waveforms (sine, square, triangle and sawtooth)
* noise generation (sirens, laser beam, random noise)
* special random sound modes

The user interface is kept very simple, with just four knobs, three puss buttons, 8 LEDs and a power switch. The speaker is connected straight to a pin on the Arduino via the volume knob - everything is done in the Arduino using PWM to generate analog waveforms. The LEDs indicate the current step in sequencing mode, and provide light patterns in noise modes.

Watchdog and Sleep functions

This example shows how to make use of the Watchdog and Sleep functions provided by the ATMEGA 168 chip . These functions are useful if you want to build low power consuming devices operated by battery or solar power.


The reduced power consumption is achieved by through a intermittent operation of the system .In case of Arduino your main loop will be executed once before the system is put into the sleep mode. After a few seconds t the watchdog wakes the system up and the main loop is executed again. The ratio between main loop execution time and watchdog time determines the amount of power that will be saved.

KrisBarrett.com » Make a Custom Arduino Shield

After many months of working on my Arduino based project, I decided to finalize my project by making my own custom PCB. At first I wanted to design a PCB that connected to the Arduino through a series of cables. After some thought however, I realized that a shield would be better because it would eliminate the need for cables. This tutorial assumes an understanding of Cadsoft Eagle. For more information about Eagle, see the Eagle Tutorials section below. Here are the steps to make your own Arduino shield:

Bidouille électronique

OK, so I finally decided to get my hands on the Arduino platform and see what all the buzz is really about. And I must say, I'm impressed. This is by far the most developer-friendly development platform I've ever seen. It's main advantages :

* It's simple. The hardware is very simple and uses standard, commonly available components. The software IDE is basic but functional : editor window, status window, integrated serial terminal. That's it.
* It's reasonably powerful. The Arduino diecimilla that I used is based on the ATMega168 microcontroller clocked at 16MHz.
* It's based on open source hardware and software (If you omit the trademark controversy about the Arduino trademark). The board design is public. This has lead to the creation of several variants and clones (Freeduino) which contributed to the popularity of the platform.
* Power, firmware upload and serial communications through a single USB cable.
* It's expandable. The concept of "shields" that can be stacked on top of the main Arduino board is genius :) As a matter of fact, making a small prototyping shield was the first thing I did for this platform.

So, a while ago I came across this great optical mouse hack by Sprite. I decided it would be great to do as my first Arduino project (beyond the "Blinky LED" example, that is.)

First step, dissection of a wireless mouse from a cheap Typhoon wireless mouse / keyboard combo.
