Hi Eugene,
I have now got to the stage with my project, where I have tested my ?Bandido Strip board? circuit as far as possible without having the proper coil.
Amazingly apart from ...one track cut... (column 18, row 20) that I forgot to include, which actually s/circuited the 0v and ?ve volt tracks (I found this on initial checks fortunately) and getting T5 a PNP and T6 an NPN transistors mixed up it all appears to work ok.

I now come to the stage where I am going to make the coil. BUT in ?Surprise !! It?s a Bandido.zip? the file ?New Image-1.GIF? and the file ?New Image-3.GIF? appear to contradict each other.
On Image-1 the Bucking coil is wound around the Transmit Coil.
On Image-3 the Bucking coil is wound around the Receive Coil.
I guess both are correct, I was going to follow the ...Image-1... as the reference frequency instructions seem pretty clear, so should I carry on.
Or should I follow the ...Image-3... instructions instead.
Can you please advise me with this as I am a bit of a novice at winding coils and don't know if one way is better than the other.

Thanks Eugene in anticipation Mike.

Mike,
Offer still stands if you need a coil to test with.....

Thanks Paul, I'll hold on that offer for now if I may, I need to wind the coils first. I have made the template for ...Coplanar Search coils by Dave Emery... and just need a bit of info before I proceed any further.

Best regards Mike.

Hi Paul, I've got some free time now...if your offer still stands, let me know...
Mike, I'll have to start all from scratch, so no news for the moment...sorry

Hi Edouard,
Just got back from holiday and saw your post.
I have been building the circuit myself recently and except for ..one extra track cut.. that I missed out ..mentioned in a previous post.. the circuit seems to work.
I am going to make the search coils now that I am back.

Edouard.. I suggest you keep on one file all the points mentioned in previous posts, so that you can refer to them easily.

I found when building the ..stripboard.. that the smaller the components used the better, because the board is so compact and that sometimes a certain way around they fitted better.

So try to fit the components into a local area first before soldering. As long as the component ends go in the right tracks its ok.

The link wire should be single strand and insulated, I used telephone wire because it had different colour coatings and was nice and thin.

I hope you get on ok.
Best regards Mike.

Hi Mike,
since I had no news from Paul, I bought part of the components tonight...everything excepted the capacitors, wich are not easy to buy...many sorts...thanks for ur help...I still need your help...now waiting for the first buy, then i'll ask you for the capacitors, then for the track cut, then for the decoupling capacitors, then for the wires etc etc...
See u soon
Edouard

Hi Edouard,
Your Reply is ..No. 47.. above, If you look back at ..Reply 40.. I have put the details of the track cut in that post,

With regard to the decoupling capacitors use ?0.1uf 63v Farnell Order Code: 1100429? they are the cheapest and I had to very carefully wire them with insulation onto the track side of the board, directly onto the ..pins 4 & 8 of the 8pin IC?s and 7 & 14 of the 14 pin IC?s...

Reply 24? gives information about capacitors, if you have not ordered them already use 0.25w Resistors, as I mentioned in ..Reply 34.. they are smaller .

I have given you various bits of information if you go back through the posts, have a read of it again and see if it is helpful.

I have built my circuit now and am in the process of making the coils, its a long project, but should be worthwhile in the end.

All the best Mike.
