I lived in Donny from '65 to '72, although I can’t remember how often we went to Finningly air shows. I think we only had tickets for the NCO’s enclosure once. We were down by the rope the day the Daleks came. William Hartnell was the Doctor who saved the world, and rode around waving to the crowd in a Land-Rover.
Fluxed braided wire makes a good solder sucker substitute as well.
Work commenced on the circuit board today with the insertion of some of the components…
One of the disadvantages of using veroboard is the need to use links between some of the tracks. Here they can be seen as copper wire connecting various stages together. They would not be required on an etched board.
Those images could almost double as a city skyline.
One of the things I could never ever do was read resister colour codes. If it didn’t have the rating written on it I would have to check the resistance with a meter.
I’ve often thought that Fruitcake…
If you can get the camera at the correct angle they look brilliant…
Once upon a time I could read the coding without specs…
Fortunately, I have a selection of specs and lenses to assist me now…:shock: But just to avoid any embarrassing mistakes I am also getting a second opinion from my multitester…
It wasn’t that I couldn’t see them and see what the colours were, I just couldn’t remember or work out what they meant.
Oh sorry Fruitcake…
I have a chart on my lab corkboard, but I know them off by heart now…
Good!
Did you want that scope and bits?
How much did you want for the scope Besoeker?
I know they are not cheap…
If you want to have it you can have it

That is a darned generous offer.

After completing the soldering and installation of all the components to the circuit board, it was time to test the circuit.
Carefully applying the voltage in steps and watching power consumption (any faults would show up as either short circuit or open circuit as the amperage increased) I reached the working voltage of 9 volt DC with a consumption of around 100mA.
After offering a metal object to the coil…It worked!..
There is still a lot of work to do, and this was just the first preliminary test. An enclosure needs to be made now to house the electronics, and the coil tidied up and modified. I saw no point in spending time on streamlining the coil if the circuit didn’t work.
To say I was delighted would be an understatement…I get so much pleasure from constructing these projects, even though I could have bought one much more efficient and professional, but what would I have learned?..
Soldering wire to wire or wire to PCB, seems OK, soldering substantial wire to heavy duty connector block is a nightmare.
I have learned nothing except to take the simple option.
That’s excellent news, old grey one.
Now to find some treasure!
You will share your profits with us on OFF, won’t you?
Well done chap. Quite often the making of something is more fun, and more therapeutic than using said something.
Last week I made rice pudding from scratch. I could have tipped a tin of the stuff into a bowl and bunged it in the nuclearwave, which would have been so much quicker and easier. However, had I done so I wouldn’t have enjoyed the experience half as much, even if all the artificial additives tasted just as good.
I know what you mean Spitty, plenty of heat required and not always possible from a soldering iron. Then you have the problem of all that heat damaging stuff it shouldn’t…
Thanks JB, I was a bit surprised myself, I usually have to bugger about with them first before they work…:surprised:
Still a while away from treading the forgotten byways and ploughed fields with detector in hand JB, and weather is crap here at the moment… But you can rest assured that the forum will benefit immensely from any good fortune I achieve…
I’ll write all about it…
Thanks Fruitcake, and I totally agree with you, sometimes it’s all about the journey rather than the destination…
I also sometimes take the long way (or traditional way) round to arrive at a satisfactory and pleasing conclusion…Life is good Fruitcake…Too good to rush…
