nice old school variable capacitor, it's hard to find ones like that anymore! One thing I found when trying to build a radio transmitter that you might find useful: you can make a tunable coil by wrapping your wire around a section of a chapstick tube, and glue some ferromagnetic material to the bit inside. washers would be a good fit probably. There's a few designs that use a tunable coil to control the frequency with a fixed capacitor, since high quality variable capacitors can be hard to find. All my projects failed but it was fun to learn.
@@pbartmess The complexity ramps up exponentially with tunable circuits, but there is a very simple FM transmitter that you can make in probably under an hour, with what you have in your bins probably. If you google "super simple FM radio transmitter" the website Makezine has a very thorough walkthrough on how to put it together. also it uses a circuit building style that I find really creatively freeing, where a copper clad board is used as a ground plane and the connections are made on little "islands" that are glued to the board. Fun stuff! One of these days when I can have an actual workspace I want to get into building circuits again. Thanks for sharing your adventures EDIT: Be careful not to add too long of an antenna or a larger power supply to this design, because if it transmits over 20 feet or something like that it becomes an FCC violation. This circuit is not designed to broadcast in the Public Band and a license is required outside of that if your signal is traveling far enough to cause interference blah blah blah etc etc etc. (sorry)
the earliest radios were "crystal sets" the crystal of graphite was used as a rectifier. I think the user had to sort of wiggle a sprung wire around the crystal to find a sweet spot... I used to wrap my antenna around the telephone cable and that enabled me to pickup loads of stations from the huge length of the telephone wires. Shame you couldn't recuse the old radio but your new one is super cool, if you can find any AM transmissions these days. Great vid Patrick!

Oh wow, my mind hadn't even progressed as far as a tunable transmitter! I will definitely be taking your advice - that sounds fun!!

this is incredibly inventive and original, the music is very cool.
Thank you!!!

A GREAT SHARE
Yeah, this came together over the course of a couple weeks and I wasn't quite sure if it would all make sense. Thanks for watching, David!
@@pbartmess YOU ARE THE MAN,
WHEN IT COMES TO THESE THINGS 😁😁🙂😁😁
Thanks for your sharing, enjoyed your interesting video!! Have a great weekend, dear my friend!

Great vid Patrick!
Thank you, Martin! I'll try the telephone wire trick. Even though I have learned the basics of how radios work I still believe it's magic.
Really cool !!! 🙂😊😀
🙂😊😀 well done !!
Thank you, Gerry!
Stayed for the tunes!
😀 Heyyy! Thank you!
Cool job👍🎉Interesting✨
@@吉井秀樹-p9w Thank you, friend.🧡
That's really fascinating, Patrick! Your music is more interesting than most of the stuff you hear on radio too!
🥰Thank you so much, Karl!
You are so brilliant! Way past my pay grade, lol! 👏👏
Haha! Thank you Cathy!! I'm just pleased that you watched the video. Have a great weekend!💛
Quite impressive Patrick! 👍👍👍
Thank you, Tomas!
My pleasure!
와우~~~
전자기기도 잘 고치시는군요~^^
역시 멋집니다~^^
😊😊😊
Thank you very much for watching!
i am a big fan of Vintage Radios and Hand Held CB's...if i'm lucky, sometimes i get a hold of a Military grade 2 Way....Awesome Vid Patrick
@@rhampton1914 When I see a vintage radio at a flea market, i can't resist buying it, even if its obviously broken 😜
haha, this is so cool! only you could say "hey, I'm gonna make a radio, create my own station and play my music on there" and actually do it!! :p
@@urbulibaba 😊 I thought that might be funny. 😊 I'm glad you appreciate it!
Am radio are cool
So magical!
