Hi all,
@here When I was young I learned a lot from "The Boys Book of Crystal
Sets"
(https://www.americanradiohistory.com/Archive-Bookshelf/Technology/Boys-Book-Of-Crystal-Sets.pdf)
and the Ladybird book "Making a Transistor Radio"
(https://archive.org/details/MakingATransistorRadio-LadybirdBook/page/n0).
These are largely unusable today, primarily because you cannot get
500pF air spaced variable capacitors (they come up second hand on eBay
sometimes at a price, but with little guarantee about actual
capacitance values). Plus they are dependent on germanium technology,
although that is accessible at least for the diodes.
I have a 10 year old nephew who is very keen on electronics. I'd like
to introduce him to the same sort of projects. Any suggestions what
the modern equivalent would be?
Thanks,
Jeremy
