In physical computing it's sometimes nice to know how physically close you are to an object. In other words, you may need to know your 'proximity' to an object, that's where the VCNL4000 does its magic. Okay, it's not actually magic, it's a combination ambient light sensor and IR proximity sensor.

The VCNL4000 can detect its proximity to an object using IR within a range of about 20cm. Proximity data as well as ambient light level data can be collected over an I2C interface. This breakout board gives you access to the I2C pins, the Vcc pin, GND and the IR+ pin (power supply for the built-in IR emitter). Simply give the board a clean 3.3V power source and give the IR emitter anywhere from 2.5-5V and you'll be able to tell how far you are from an object up to 20cm.

Features:

• Voltage Rating: 3.3V
• IR Emitter Vin: 2.5-5V
• I/O pins are 5V compliant
• Range: Up to 20cm

Surface transducers give you the awesome power to turn almost any surface into a speaker. They're essentially just a speaker except instead of a cone, the coil is attached to a pad that conducts the vibration into whatever you press it against. Hook it up to an audio source and press it against the nearest table, wall or cardboard box. You can even put it against your head and play music directly into your skull (the ultimate surround sound).

Note: We are waiting on a datasheet. However, these have a 4 ohm nominal impedance and can handle about a watt continuous.

Pulse oximetry a noninvasive method of indicating the arterial oxygen saturation of functional hemoglobin. Oxygen saturation is defined as the measurement of the amount of oxygen dissolved in blood, based on the detection of Hemoglobin and Deoxyhemoglobin. Two different light wavelengths are used to measure the actual difference in the absorption spectra of HbO2 and Hb. The bloodstream is affected by the concentration of HbO2 and Hb, and their absorption coefficients are measured using two wavelengths 660 nm (red light spectra) and 940 nm (infrared light spectra). Deoxygenated and oxygenated hemoglobin absorb different wavelengths.

VS1053b from VLSI is a single-chip Ogg Vorbis/MP3/AAC/WMA/MIDI audio decoder and an IMA ADPCM and user-loadable Ogg Vorbis encoder. It contains a high-performance, proprietary low-power DSP processor core VS DSP4, working data memory, 16 KiB instruction RAMand 0.5+ KiB data RAM for user applications running simultaneously with any built-in decoder, serial control and input data interfaces, upto 8 general purpose I/O pins, an UART, as well as a high-quality variable-sample rate stereo ADC (mic, line, line + mic or 2×line) and stereo DAC, followed by an earphone amplifier and a common voltage buffer.

VS1053b receives its input bitstream through a serial input bus, which it listens to as a system slave. The input stream is decoded and passed through a digital volume control to an 18-bit over-sampling, multi-bit, sigma-delta DAC. The decoding is controlled via a serial control bus. In addition to the basic decoding, it is possible to add application specific features, like DSP effects, to
the user RAM memory.

This version of the QRE1113 breakout board features an easy-to-use analog output, which will vary depending on the amount of IR light reflected back to the sensor. This tiny board is perfect for line sensing applications and can be used in both 3.3V and 5V systems.

The board's QRE1113 IR reflectance sensor is comprised of two parts - an IR emitting LED and an IR sensitive phototransistor. When you apply power to the VCC and GND pins the IR LED inside the sensor will illuminate. A 100Ω resistor is on-board and placed in series with the LED to limit current. A 10kΩ resistor pulls the output pin high, but when the light from the LED is reflected back onto the phototransistor the output will begin to go lower. The more IR light sensed by the phototransistor, the lower the output voltage of the breakout board.

These sensors are widely used in line following robots - white surfaces reflect much more light than black, so, when directed towards a white surface, the voltage output will be lower than that on a black surface.

The power input and analog output pins are brought out to a 3-pin, 0.1" pitch header. The board also has a single mounting hole if you want to screw the board onto something.

We also have an digital version of this board.

The e-Health Body Position Sensor monitors five different patient positions (standing/sitting, supine, prone, left and right.) In many cases, it is necessary to monitor the body positions and movements made because of their relationships to particular diseases (i.e., sleep apnea and restless legs syndrome). Analyzing movements during sleep also helps in determining sleep quality and irregular sleeping patterns. The body position sensor could help also to detect fainting or falling of elderly people or persons with disabilities.

You can find our e-Health Sensor Platform Complete Kit to get a complete First Aid Kit for Makers or buy the e-Health Sensor Shield separately.

IMPORTANT: The e-Health Sensor Platform has been designed by Cooking Hacks in order to help researchers, developers and artists to measure biometric sensor data for experimentation, fun and test purposes. However, as the platform does not have medical certifications it can not be used to monitor critical patients who need accurate medical monitoring or those whose conditions must be accurately measured for an ulterior professional diagnosis.

This tiny breakout board features the ADMP401 MEMs microphone. One of the key advantages to this breakout and microphone is the bottom ported input. This means the microphone's input can fit flush against the enclosure of your project. Plus you will not have to deal with trying to solder the microphone's wacky footprint. Wootness!

The amplifier on the breakout has a gain of 67 and more than meets the bandwidth requirements of the mic. The amplifier's AUD output will float at one half Vcc when no sound is being picked up. The amplifier produces a peak-to-peak output of about 200mV when the microphone is held at arms length and is being talked into at normal conversational volume levels. So the AUD output can easily be connected to the ADC of a micro.

Features:

• -3dB roll off at 100Hz and 15kHz
• 1.5 to 3.3VDC supply voltage
• Should comfortably output 40mW
• SNR of -62dBA

The MIDI Breakout board gives your Arduino or any other microcontroller access to the powerful MIDI communication protocol. The MIDI protocol shares many similarities with standard asynchronous serial interfaces, so you can use the UART pins of your microcontroller to send and receive MIDI's event messages.

The MIDI Breakout provides both MIDI-IN and MIDI-OUT connections, as well as a MIDI-THRU port. The MIDI-IN port is opto-isolated to prevent ground loops. The MIDI Breakout board can be mounted directly on top of an Arduino like a shield, connecting the MIDI-IN/THRU to the Arduino's hardware RX pin and the MIDI-OUT to TX. All of the Arduino's digital and analog pins, as well as power and ground busses, are broken out as well. The RUN/PGM switch allows you to program the Arduino over serial without having to remove the shield.

Note: The MIDI Breakout does not come with the three through-hole MIDI connectors soldered; these connectors are included with the product, however.

Want to sound like a robot? The HT8950 is a single chip CMOS LSI voice modulator ICs which provide seven steps to shift the frequency of an input voice, producing a dramatic change in the output.

The HT8950 provides two special effects: vibrato and robot. The vibrato effect is generated by alternating the frequency of an input signal up and down at a rate of 8Hz. The robot function, on the other hand, converts an input voice into a robot voice. Both effects can be selected depending on which pin is triggered, either ROB or VIB. For the output frequency level shifting, the chips provide seven steps which can be selected from the two groups of pins namely, SW0, SW1 and SW2 for electronic direct selection and ROB, TGD, TGU and VIB for push button selection.

The HT8950 include a built-in microphone amplifier with an internal bias, an 8-bit A/D converter, a built-in SRAM as well as a current output type 8-bit D/A converter. The 8-bit A/D and D/A converters with a sampling rate of 8kHz ensures a high quality and high S/N ratio output voice.

A simple flex sensor 2.2" in length. As the sensor is flexed, the resistance across the sensor increases. Patented technology by Spectra Symbol - they claim these sensors were used in the original Nintendo Power Glove. I love the Nintendo Power Glove. It's so bad!

The resistance of the flex sensor changes when the metal pads are on the outside of the bend (text on inside of bend).

Connector is 0.1" spaced and bread board friendly.  Check datasheet for full specifications.

Note: Please refrain from flexing or straining this sensor at the base. The usable range of the sensor can be flexed without a problem, but care should be taken to minimize flexing outside of the usable range. For best results, securely mount the base and bottom portion and only allow the actual flex sensor to flex.

This is a small force sensitive resistor. It has a 0.16" (4 mm) diameter active sensing area. This FSR will vary its resistance depending on how much pressure is being applied to the sensing area. The harder the force, the lower the resistance. When no pressure is being applied to the FSR, its resistance will be larger than 1MΩ, with full pressure applied the resistance will be 2.5kΩ.

Two pins extend from the bottom of the sensor with 0.1" pitch making it bread board friendly. 

These sensors are simple to set up and great for sensing pressure, but they aren't incredibly accurate. Use them to sense if it's being squeezed, but you may not want to use it as a scale.

Dimensions: 

• Overall length: 1.75"
• Overall width:  0.28"
• Sensing area:  0.3"

Datasheet

These body electrodes were originally manufactured for use in electric therapy. While we can't condone the use of these in medical therapy, they can be useful for hobby applications. Each electrode is essentially just a conductive pad coated with adhesive gel and terminated on the opposite side with a snap connector. These electrodes are sold in pairs along with an electrode lead with a snap connector for each at one end and a 2.5mm jack at the other.

Although we have no information available regarding the voltage and current tolerance of these electrodes, it's probably safe to say that they will handle much more power than you would ever want to conduct through soft tissue!

The adhesive is a gel similar to what you might find on Pasties or those sticky hand toys you (try to) win at arcades and carnivals. After a few applications, the gel collects contaminants and becomes less adhesive, rinsing them with water will help it regain its adhesive properties.

Note: This product is NOT a medical device and is not intended to be used as such or as an accessory to such.

Features:

• 5ft cable
• 2.5mm connector
• 2x3" Electrode
• Self-Adhesive
• Snap connectors
