Projects 4 kids

Update 2021-08-12 : the website with the information about these kits, isn't registered any more. I contacted Chris PE1DZX about this and he was so kind to allow me to host the 2 PDF's containing the building instructions from the crystal radio kit and the active radio kit. 

Building instructions (in Dutch) : Bouwbeschrijving kristalradio and Bouwbeschrijving Actieve schuifradio  These are copyright Chris Dorna PE1DZX. 

Big credits to Chris for allowing this. 


A few weeks ago I bought a handfull of components and  materials to build 2 crystal radio's to put on stock for a rainy afternoon. A few days later it was one of those days that rain was the only thing to see outside. So I decided to do a technical workshop afternoon with the kids.

The kids where supprised and eager to learn about this strang radio where you don't need a battery to get music.They made the component placement them self and only needed a bit help creating the coil holder. The design was based on the simple passive crystal receiver from Chris Dorna (PE1DZX) and we added even a few minor upgrades to it.

After every thing was placed and finished up, we went to the attic to hook up on of the the long wire's I use for HamRadio listening .

They were very surprised by the results and even wanted to a large multi section Air variable capacitor.

 

Update 10 march 2013 : To surprise the kids on a other rainy day, I ordered 2 new kits from Chris which are active slider radio's  

As always in the Netherlands, there isn't a shortage on rainy days, so they build them. Unfortunately we didn't take any pictures during the process. But the radio's work marvelous and they sometimes use them for fun.
