I just received jolly friendly email from Lauren Davis, who is the Marketing Manager at Parallax. Lauren was keen for me to share the news that the folks at Parallax recently released four exciting new products as shown below...
Polar Heart Rate Receiver
The Polar Heart Rate Receiver is a Polar WearLink-compatible receiver capable of wirelessly receiving coded heart beat transmissions from the Polar WearLink+ Heart Rate Sensor. With its standard servo interface pinout (Vss, Vdd, Sig), interfacing with this receiver is very simple - upon receipt of a heart beat signal, a 15 ms pulse is sent on the signal pin. This receiver also features a longer reception distance, giving you added flexibility in your application.
- Receives coded or non-coded signals from Polar Heart Rate Transmitters.
- 100 cm - 125 cm reception distance gives you greater range from the transmitting heart rate sensor.
- Long 15 ms pulse on received heart beat gives your processor ample time to sample a pulse.
- Interface connector is not preinstalled to give you prototyping flexibility.
- Standard servo connector compliant for easy interfacing.
part #28048. Price: $29.99Polar WearLink + Coded Heart Rate Sensor
The Polar WearLink+ Coded Heart Rate Transmitter monitors and then wirelessly transmits your heart rate data from the chest strap to a Polar WearLink-compliant receiver
. This allows the wearer to monitor their heart rate and related bio-metric statistics. This transmitter can be paired with your local gym's exercise equipment if it is Polar WearLink compatible.Key Features:
- Heart rate sensor wirelessly transmits heart rate without the need for conductive gel.
- Water-resistant up to 30 meters for use in extreme environments.
- Coded transmission prevents cross-talk from other noisy devices.
- Battery to last up to 2000 hours of continuous usage.
- Adjustable elastic strap for comfortable yet secure sensing.
- Removable and machine washable textile strap keeps your sensor bacteria-free.

Dual Relay Board Kit
Once properly assembled, the Dual Relay Board Kit allows you to control two high-power devices up to 8A each via the included Omron mechanical relays. The Dual Relay Board can be used to turn lights, fans and motors on/off while keeping them isolated from the microcontroller. Independent control of each relay is provided via a 2 x 3 header making it friendly with servo cables and providing a convenient connection to many development boards, such as the Board of Education, Propeller Board of Education, Professional Development Board and Propeller Professional Development Board. LEDs indicate relay status.Features:
- Comes as a kit providing lower cost.
- Control two high-power devices with one kit.
- Provides isolation between microcontroller and device being controlled.
- Easy screw terminals for relay contact and power connections.
- 3-pin servo style headers for easy connection using standard servo cables.
- LED indicators provide status of each relay.

part #27114. Price: $19.99Stampduino
BASIC Stamp development board designed to be compatible with most Arduino shields, reducing space and size requirements, with the purpose of optimizing the users systems.Features:
- All 16 Digital I/O pins are free to use, allowing you to fully utilize the capabilities of the BASIC Stamp.
- Compatible with most Arduino shields, for ease of use between systems.
- Integrated Serial Communication LEDs for a visual confirmation of data transfer.
- Surface mounted 3.3 V regulator to accommodate the incorporation of 3.3 V devices into your application.
- USB or externally powered, for those who do rapid prototyping.
