This 0.005" Muscle Wire (aka Nitinol) is a one foot long piece of nickel-titanium alloy that can flex and contract when a specific amount of heat or current is applied to it.
This 0.012" Muscle Wire (aka Nitinol) is a one foot long piece of nickel-titanium alloy that can flex and contract when a specific amount of heat or current is applied to it.
This is an excellent choice for anything that requires a small battery with a lot of punch. The voltage is low enough not to tax your regulating circuits, and the discharge rate is high enough to accommodate a lot of electronics and a few small motors. The battery has two cells and outputs 7.4V storing 1000mAh of charge.
Plug your power supply into one end and the other into your project and, just like that, you've got a power switch! The on-off rocker switch has a good stiff 'click' to it, so it isn't easy to accidentally switch. It's also fairly small so it won't add too much unnecessary bulk to your project.
After you've assembled it, simply plug the RaspiRobot Board into the GPIO port on the Raspberry Pi and it provides dual bi-directional motor controllers, two open collector outputs, two switch inputs, a pair of status LEDs and even a voltage regulator capable of powering the Pi using a battery source from 7-12VDC.
These are a longer version of our standard break away headers. They are 20mm long which allows you use them socket to socket. The plastic separator can be slid up or down to accommodate your needs. You will get a row of 40 pins. They can be broken or snipped to length.
