Maker SHED

A fun science kit designed to excite and engage experimenters of all ages as they recreate the experiments that lead to the development of the first successful electrical telegraph. Build your own working telegraph with a device designed to work as a sounder, a buzzer, or a relay. Learn Morse Code and Electromagnetism.

Included in this kit:

• Telegraph (with built in coil winding arbor)
• Telegraph key
• 2 coil bobbins
• 100 feet of hookup wire
• Test Leads
• 24 page full color instruction manual.

Not included: (and required)

• 2 6-volt alkaline lantern batteries

List of Experiments Included in the Manual:

• Your First Telegraph
• Encoding Messages
• Making a Buzzer
• Making a Relay (and connecting multiple sets)
• History of the Telegraph

Concepts Taught by this Science Kit

• Electricity and Circuits (uses and effects)
• Magnetism / Electromagnetism
• How a sounder, buzzer, and relay work.
• Encoding messages and computer principles
• Forces and Motion (strength of an electromagnet)
• The Scientific Method
• History of the Telegraph and Morse
• Invention and the Inventive Process

“The hands-on angle of what you [Bennett Harris] are doing is crucial to a sound learning experience. We have too many scientists these days who depend solely on computers and models and who have zero practical experience in the real world. I've interviewed EE graduates who have never built an electronic circuit! Keep up the good work.”

“I would have loved this kit as a kid.”

“You’ll experience the thrill that Thomas Edison must have had when he creating his first working bulb.”

Natania Barron (The Geek Mom Blog)
“Sure, there’s a ton of science kits out there. But what I love about the Harris Educational products is that they allow you to do such cool and interesting projects with your kids. How about making a light bulb? Or a telegraph? These kits come with everything you need to do just that. I particularly like the steampunk angle, considering the approach to making these items are very old-school, yet the results are undeniably awesome.”
