This 0.005" Muscle Wire® (aka shape memory 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. If you are asking yourself “What sorcery is...

This is a replacement soldering tip for our Hakko FX-888 soldering iron. This is the chisel type of soldering tip that comes with the Hakko. Replacing the tip is very easy - simply unscrew the shield, slip the replacement tip in, and...

This is a single pole, 10 position rotary switch able to select up to 10 different states in a durable package. Unlike our other rotary switch, this model is much more robust and capable of handling larger currents and voltages. With a...

This miniature straight bar load cell (sometimes called a strain gauge) can translate up to 500g of pressure (force) into an electrical signal. Each load cell is able to measure the electrical resistance that changes in response to, and...

Polymorph is a non-toxic, biodegradable polyester with a low melting temperature of about 60°C (140°F). Prototype plastic parts can be made by simply heating the plastic beads in hot water until they turn clear and then kneading them...
