Solderless Choccy Block / Terminal Strip Crystal Set Radio Kit of Electronic Parts

This is a kit of electronic parts which will allow you to build a good crystal set radio using modern parts as detailed at the following link:


Please try searching for "The Choccy Block Crystal Set Radio Kit."

I have found it to be much better than the commercial plastic kits available thanks to the use of the output transformer and the use of an aerial input coupling coil. All the earphones are tested.

This is the Bill Of Materials:

* 3 Amp terminal strip
* LT44 transformer L2
* variable capacitor VC1
* 2 M2.5 4mm screws
* 3 M2.5 20mm screws
* 3 M2.5 nuts
* 5 M2.5 washers
* BAT48 schottky diode D1
* 470pF ceramic disc capacitor C1
* ceramic / crystal earpiece Y1
* 30SWG / 0.315mm enammeled copper wire 4m
* 1m yellow aerial connection wire
* 1m green earth connection wire
* 1 yellow insulated crocodile clip
* 1 green insulated crocodile clip
* control knob for short shaft
* 50mm long, 9.5mm diameter ferrite rod
* 100mm single core red hookup wire
* 100mm single core black hookup wire

All the build information is provided online so that easy updates can be added. There is no paper documentation supplied.

The particular thing that I like about my kit versus so many others, is that if you live in a flat and can't put up a decent long-wire aerial, you can always go on a walk and attach this portable version to two wires on a farm fence to get a signal.

The connectors do not work well with multiple wires. The smaller gauge wires tend to pull out easily. I had to solder the wires together to make it work. Once that was solved it works well. I was able the receive our two local stations with only a short antenna.

Response from Henry Walmsley

Thankyou for the review. Soldering will always make a better connection than any other method when you have the skill and tools to do it.

My eight year old nephew was so excited to receive this as a birthday gift. Great little kit, packed well, with easy to follow instructions available on the web (I appreciate the lack of paper instruction book for environmental reasons). Looking forward to seeing how he gets on with building his radio.

Response from Henry Walmsley

Thanks for the 5*s. I hope it works well.
