For those who like to design and build there own Crystal Radio set ( Xtal Radio Set ) we sell the parts (1N34A Diode, Ceramic Earphone, Piezoelectric Earphone ).
Building Crystal Radio Kits ( Crystal Diode Radio Kits ) are a great way to introduce young people to electronics. My kits are easy to build and Crystal Radios do not use external power sources other than an antenna and ground. The principles of a Crystal Radio Sets operation are not hard to understand.
Science Fair Crystal Radio Projects
Building Crystal Radios have been very popular as a Science Fair Project for years. A Crystal Radio Science Fair Project teaches many fundamentals of electronics. Many parents built Crystal Radios as there Science Fair projects when they were in school and want there children to build a Crystal Radio Set and enjoy all the fun they had learning how the Crystal Radio Set worked.
If you are thinking of building a Crystal Radio Kit as a Science Fair project then our Simple Crystal Radio Kits are a good choice. Our Simple Crystal Radio Kits come with all the components needed to make the Crystal Radio Receiver. Optional components are the Knobs, Fahnestock clips. The mounting boards and Antenna and Ground Wires are not included.
If you want to build a more elaborate Crystal Radio Science Fair Project maybe winding your own Crystal Radio Coils like the Quaker Oat Box Crystal Radio then you can purchase some of the hard to find Crystal Radio Parts here from our wide variety of Crystal Radio Resources and Components like Crystal Radio Earpieces. Some Quaker Oat Meal Box Crystal Radio Supplies I sell are magnet wire and Solder Lugs.
I will also be making my own type of Oat Box Crystal Radios later on this year. My Oatmeal Box Crystal Radio will not require the taps on the coil and my Oat Box Crystal Radio work better and be easier to make than the other types of Oatmeal Box Crystal Radios on the internet now.
Email me if you have any questions on what to purchase for your Crystal Radio Project. Quaker Oat Box Crystal Radios supplies can be purchased here.
Learning how to build a Crystal Radio is a great way for anyone to get started in the electronic field. Great for Science Fair Projects and Boy Scout projects. The Simple Crystal Diode Radio Sets we have for sale are a fun way for the family to spend time together. As a child I made Crystal Radio Receivers out of things I find in old scrapped Radios and TVs. Most had no tuning capacitors. I had to tune in stations by sliding a ferrite rod in and out of the tuning coil. I would spend days trying different items to use as a detector instead of a diode, some worked but most did not. Anyway I had fun learning. Buy one of our Crystal Radio Kits for hours of fun and learning.
