In all these experiments make use of the contacts between the blades of the Light Mill. It's easy when you attach a piece of flexible electrical wire here. Stick a piece of tape over the light sensor.
Color the patches starts and finish with a soft black pencil (preferably 6B). Slide the metal surfaces
paperclip on the surfaces, connect the wires to the paper clips. Draw a path through the islands and bridges. If the path is well marked, without interruptions, the mill will run faster.
Lost your wire???
In a pile of wire ends it is sometimes difficult to find the acompanied ends. Try it with the LightMill!
Pak both the end of a wire of the Light Mill bite. Join hands, watching a good look at what happened!
Which materials conduct electricity? Try it with the Light Mill!

Connect different resistances between the wires. What can you say about the speed of the mill and the value of the resistor?
Every year, the Service Kring JOTA-JOTI developed a building kit for the scouts to solder themselves and then enjoy themselves with the result.
For this year, "The Morse Phone" has been developed, as the name suggests, you can start with this kit with Morse code. The Morse Phone is a Morse-buzzer that can be used independently, but can also be linked with other Morse Phones, communicating, after all, is done in pairs! The Morse Phone is inspired by the Fuller phone. For the technicians, an article on this subject can be found elsewhere on this website. Google also gives a nice explanation of the origin and use of the Fuller phone
The kit comes with all the components except the 9Volt battery.
Now that a large number of Morse phones have been shipped, we've also received feedback from our customers and we'd like to share it with you.
