Memory wire is simply brilliant and brilliantly simple! If you have not tried it yet, here's your chance to have a go!. Signals, Point actuation, Crossing gates - the uses are limited only by your imagination.... The kit includes a metre of 150 µm Memory Wire - that's a heavier, more robust grade than you normally purchase in mainland Europe and sufficient for 8-10 actuators. Ample Crimps and Solder Tags, various sizes of Springs, a couple of Cranks, a voltage stabilizer and Resistor so you can run the actuators from your existing 12VDC supply, or from a battery box so you can get going straight way - so useful whilst installing and testing your ideas. Plus the C+L bonus: three pages of hints, tips, wirings diagrams, data and explanations.

As you can see from the above, all components are available individually. But please buy the complete kit to start with. It contain 4 pages of hints, tips and instructions. Without this, you are likely to burn out the wire....
