Same here JB, and there’s nothing wrong with me…
Errr, well, not counting two heart attacks…

Very neat and well laid out.

When I was a bench engineer (or technician), the company showed concern about flux fumes affecting my asthma. I told them I wasn’t worried because it didn’t seem to affect the condition.
It can’t have been too harmful because I’m the age I am and still got puff for brisk walks and bike rides.
Anyone who uses a soldering for work or hobby must have breathed in quite a lot of fumes from flux-cored solder.

Well, I don’t use flux-cored, but I paint flux on the surface before I apply solder. I think it smells quite nice.

I know what you mean Mart, but I suppose smoking twenty cigs a day for 35 years won’t have done me too much good… Good job I stopped when I did…
Sometimes flux is just a load of old Borax. ;-)
I apply flux when doing plumbing JB, but it’s not really practical on a circuit board…
I used to buy multicore solder from an electronics shop, and then one day I was wandering round a Motorists Discount Store and exactly the same solder was a third of the price. It seems that depending what you want the solder for, governs the price…
It makes the pipes go a funny colour if you don’t wash it off…

I agree. On the very few occasions when I have soldered small wires and components together on a circuit board, I haven’t used any flux.
Actually, it was quite a long time ago and I don’t remember much, but it is possible that the solder contained flux.
Do you need to use flux if you are wiring up a flux capacitor?
Sorry I’m having a silly day today, or a normal day as my Lovely Cousin calls it.

I have done some plumbing with a blowtorch, flux that looks like diluted Marmite and solder thick enough to make coat hangers out of. It’s quite satisfying watching the solder run around the joint. Also used those joints that contain their own solder. Quite good seeing the molten solder appear at the edges of the joints.

I flux things right up. Done it quite often.

They are known as ‘Yorkshire Fittings’ Mart…

There seems to be an influx of humour today…
Sorry JB, I don’t know you well enough yet…
Perhaps we could start with a drink together and take it from there…

Just as long as you’re paying. I am a Yorkie, of course.

After reaching saturation point concerning Brexit and Covid, I thought I would escape for a while and concentrate my energies on a project in the workshop.
Most members might find it as interesting as removing wax from their ear with a hairgrip, but for the odd one or two I thought it might prove interesting and different, so I’ll post my progress…or lack of…
How to Build a working Metal Detector. …Hopefully!..
Before I jump into the technical stuff I must point out that building a metal detector is not a new thing for me, I managed to build a reasonably decent BFO (Beat Frequency Oscillator) detector back in the eighties.
Again, just last year, I found a decent drawing on the net that appeared to be more sensitive that my previous version, so on and off over the last twelve months I’ve been assembling it, unfortunately after extensive testing, studying the drawing until I went blue in the face, and fault tracing I’ve been unable to find what the problem was…
This was the circuit…

A metal detector needs a search coil…The bit that skims the surface of the ground and picks up any fluctuations in either RF waves or Magnetic waves when metal is located. In most cases it is the hardest bit to construct, so before I start this kind of project, I see if I can produce a good search coil, the circuit is usually the easiest bit for me…supposedly. This was the search coil for my first attempt…I was quite proud of it…

Oh my word! You’re a genius! Just the other day I was
saying that I needed to get a metal detector!
