How can I Scavenge/Salvage a crystal+audio transformer from an old radio (or anything!) for an AM transmitter project? Answered
Hi! My name's Bashu, I'm 18. My electronics skills are pretty feeble but I think I'm trying to get a better idea about how they work.. by making projects! old homeschooler reflex.
So my brother has an old 1982 lovable Toyota Tercel named Humphrey. Humphrey was passed on to my brother the way God or Toyota made him.. with an AM radio. This is pretty rad if we want to hear Chinese/Spanish/Italian radio jockeys (they have really nice vocal rhythms), except usually we don't for some reason.
So I wanted to make an AM transmitter. I found a project on here.
Looks pretty simple. Requires an approx 1 mhz crystal and an 8-1000 ohm audio transformer, which I was prepared to buy, except then I heard about salvaging them from cheep radios! VERY EXCITED WAS I! I love reusing old things that were once very incredible (taking songs out of the air? Magic) and would otherwise go to the dump.
Alors, I bought an old clock-radio from a thrift-store, opened it up and looked inside, and realised I had no freakin' idea what the crystal or audio transformer would look like.
I then decided to enlist the help of the only community I thought would know. You! My question is, if I wanted to find a 1 Mhz Crystal and a 8 into 1000 ohm audio transformer, without buying them, where would I be likely to be able to salvage them, and what will they look like? Pictures of the radio I bought and opened up are attached, in case they are on there and easily spottable. I don't mind digging. Thank you very much for any advice you have!
I am also thinking it would be really cool to have an instructable dedicated to salvaging components from various equipment. I found a wiki on it, but it's somewhat incomplete and has no photos whatsoever.
