White LED key ring light kits designed as an introduction for Key Stage 2 & 3 students to design and make in electronics.
Project notes are available as a free PDF download and are designed to be photocopied for class and teacher use. Notes include suggested lesson plans and mapping to the National Curriculum, an introduction to circuits and symbols, batteries, LEDs and pricing and costing exercises and a series of homework assignments to support work in class.
LED colour: White
Students start by investigating the need for security and the problems of using locks in the dark
They can then complete the design process of a mini-light, which can be attached to a key ring
With careful organisation it should be possible to manufacture the design without specialist workshop facilities
The component kits include batteries and LEDs, plastazote foam core and high impact polystyrene outer layers
Q. i would like to purchase kits with the white LED for cub scouts. Is the foam thick enough for three batteries to sit in? I know very little about electronics so don't want to wire anything?
thank you
A. Hi V Greenwodo. Thank you for your question. These do not require soldering and come complete with batteries and instructions.

It is very useful to be able to order the parts as a kit. However the problem is with the platic which is supplied. The material for the plastic of the outer casing is just too thick. Even adults need to be regular gym goers to have enough strength to squeeze the sides enough for the torch to light.
