Building a Radio - 18 Dec 2007


On Tuesday (two weeks ago) Stephen & Zac joined a small group of homeschoolers and started to build a Radio at Peter’s place. Peter took a session on the Mightly Electron in October and has great enthusiasm for electronics.
This Radio will not be using any electricity and will be able to be listened to 24 / 7 ! The children started out by making a capacitor  out of cardboard, silverfoil, stickytape and some wire. That took so long that another session had to be scheduled.
For "homework", the boys had to wind some wire 12 x around a fruit cardboard box and then, this Tuesday, they had the opportunity to join up the capacitor to the wire.
Peter made a tuner to go into the capacitor so they could receive a few of the AM stations.

Once it was all connected, they could have a listen through an ear piece.
Like all radios, you have to move it around to get the best reception!
They were able to pick up 3 or 4 stations and Peter has offered another session to make a speaker, powered by a 9 volt battery so that they can have amplified sound.
