Nostalgia: *** Smith Electronics Fun Way into Electronics

Gough Lui
Gough Lui over 11 years ago

A little while back, I did a little blogging about *** Smith Electronics Fun Way into Electronics series. This was arguably one of the main things which got me into the whole electronics hobby, so I thought some of you might also enjoy looking back at *** Smith when it was more than just a consumer electronics shop. If you remember these, or have any thoughts to share, I'd love to hear them image.

    I forgot to say that SOLDER SMOKE is a great old school pod cast done by this American guy out in Rome.

    I think it's the same chap who formulated the WSPR stuff correct me if I'm wrong?!?!?

     

    BTW Shabaz he has a bit on those SI5351 synthesizers Cool components had!

    Just had an idea I could use some plastic cogs to form a reduction gear to improve the tuning ..couldn't say the acrylic wasn't a good insulator ...probably good Permitivity  as well image

    Ah! Good point. I've only seen the relay switched inductor/capacitor ones, for about 20W or so. The motor method would be way higher.

    No way!!!

    This is great! A shame the video cannot be found on the BATC site. I wonder why they don't make use of youtube, for greater visibility of all the amazing material they probably have.

    You have the kit  no real excuses and you can even involve the Nephews. get them running the wire down the garden.

    Get a reel of enamelled wire from say Maplin or something and job done

    You can use these for some moderate power RF. The continuous ones are useful if you want to do some automatic Tuning .

    A mate of mine uses a remote arduino type thing with a motor to turn one of these caps to tune up a large loop antenna in the garden.

    They are in better condition than I thought. The smaller one I don't know much about (but has a geared drive - very cool) and the longer one is a Jackson Brothers one, with continuous rotation so would need some end-stops or cord drive I guess. It looks silver-plated, and is unused, so I've put it back in the bag in the box - I want a _really_ nice radio project to use that : )
