Ugliest CCT Board...


I thought I would try the old 1970`s style Wire-Wrap technique for the RAM board of my latest project.
and although it`s great fun to do in bed watching TV (my wife banned me from using a soldering iron LOL), the end result can be a bit Ugly!

anyway, here`s my Contribution for "Ugliest Circuit":

so... DO Share your Ugliest CCT, I`d hate to feel all Messy on my own!

OK, beat this one:

--Log in or sign up to see linked image content--

This was a little circuit designed using a 555 timer intended to drive a radio control servo unit, to make it take up a position dependant on the setting of a potentiometer. It worked well once I'd messed about with some component values.

I now use it to tune out the inductive reactance of an overly-long 80m antenna, by using the servo to operate a variable capacitor at the antenna base.

The circuitry has been tidied up and a circuit board made, and the device now sits in a box at the radio position to enable me to tune to almost 1:1 SWR anywhere around the 80m band.

I totally love your regulator "cluster", I`v done similar myself in the past, I gather it`s a 7805 or similar?

Yep, 7805, freely available from old tellies and suchlike. In fact, I paid for nothing there, all from the junkbox except the servo, which I scrounged.

Note the 555 mounted in a 16 DIL socket. You gotta improvise!

Actually... (looks about a bit...)
Here's the finished 'product', neatly packaged on a circuit board and fitted into an old computer PSU box, using most of the same components:

As you can see, I develop a project to the point where it works, but never 'prettify' it.

As if to prove a point, here's the antenna tuner itself, securely housed in a mil-spec plastic biscuit tin:
