REED SWITCH MOTOR KIT Reed Switch Motor. Project for a simple motor. As one of the 2 fixed magnets passes the reed switch it closes and energises the coil. The interaction of the electro-magnet and the permanent magnet produce an incredibly fast rotation of the rotor. Requires some use of hand tools and soldering (or crocodile clips to join the wires). Requires 1.5V AA battery (not included). Ref: CDT0226 | Price: £4.99 |
BUILD YOUR OWN GENERATOR KIT. Generator Kit. Educational project designed to show how a DC motor can be used to convert movement into electricity. 65 pieces with metal side frames, gears, motor and bulb. Includes spanner & screwdriver. Ref: CDT0092 | Price: £18.90 |
ELECTRONIC SPEED COUNTER: Electronic revolution speed counter with LED display and slotted opto-switch. With a circuit board and external slotted opto-switch the actual speed of the hotair motor or the steam engine can be measured. The scale of 12 LEDs cover the range from 0-1500 in steps of 125RPM. With small changes in the circuit even higher speeds can be read. Parallel to the LED's a high ohm measuring device or oscilloscope can be coupled to make an even more accurate reading. Needs a 12V DC supply. Ref: CDT0229 | Price: £17.99 |
