Surf Pi boards available now - longboard

[KORRIGAN]

thank you, silverdog

I received the package yesterday, good quality

congratulation for your job

cordially

[Rov]

silverdog so this pcb works with C15 electro in reverse position as per your Picture?
_ neg of capacitor to + on position for pcb ,or is this an error,with something?any more inconsistancies to watch out for?
What about you other builders?any comment,must be a few by now for this project,eg.positioning of the 1w damping resistor may lead a few to error also,several pads this may logically solder this to.an they arent all correct.

I notice some undertone ?? Lets be strait, Nobody make's some monay on this board, Silverdog is given some service ... a very cheap board from high qualety !
I have made this design at first only for myself and for some friends that are divers.
So no money making... only good intensions.....

Well C15 is for the negative power, so the minus is going to the neg. supplay, the + is going to ground. Plaese explain in detail wat you mean around the damping resistor ?

Only the position from some potentiometer can be turned 180 deg. for working the right way, for me this was not the problem, I only adjust them at first setup. So to make this clear ...some potentiometer work counter clockwards instead of clouckwards.
If I am wrong... let me know ...

Well hope we stay friends...

Best regards.

Hello Rov.

Some boards I made to see if al works ...do not take te componets value's I used to exact, I thake wat I have in random order.. So the damping resisters are to low...
But the boards all work.. the tune resistor (last board not there ) needs 180 degr. turn to work normal, but if you think counterclockwards for tune it is not a problem.

No undertones intended,just you look clearly at post 3 picture you see capacitor C15 with jacket of electro cap -negative to + of pcb mask is all.now none of your pictures are in this fashion from later posted pictures.
We all appreciate the hard endevours in producing these pcb at low cost,for all to share.but be clear there is error here as to the photo.
so simply acknowledge .please.an we all move on to a fine built machine.
I anticipate several pcb from silverdog to build shortly myself for holiday project.
If my thoroughness irritate you ,I am sorry.

There is no problem with C15. The fact that it is oriented the other way round to C13 and C14 may be causing some confusion. The solder mask shows the +ve terminal is at the bottom, and the images shows C15 has the -ve terminal at the top. Also, the -ve terminal is connected to pin5 of the 7760, which is the -ve output. Everything looks perfectly ok to me.

Hello Rov

Yes, you are right! the C15 cap at the photo in post no.3 is in the wrong orentation, it has to be 180 degr. turned. I am sorry for my (to) fast conclusion...
Look at the photo from the 3 boards how C15 its orentation must be.
Hope you make some nice good working detectors in your holiday !

Best regards.

Fine!orientation may be causing confusion?,lets hope you or others never get confused with orientation with your electro caps.maybe your projects may or may not work,just the jacket of electro cap with negative strip always ment - negative when I went to school.and always the Caution to orientate your electro caps the correct way!
Look at post #3 for your picture,What do you see?
Apberg pictures are correct #19.
We all learn,You and me.

Rov

you are correct my cap was the wrong way round, funny thing is it didn't seem to make any difference.
The damping resistor should be placed as per the silkscreen, the other 2 pads underneath are no longer required as the boards are thru hole plated and they used to be used for a link between tracks - just 2 jumpers are now required which can be seen in apbergs last photo - the one by C6 allows for his LED option
The new batch of boards, which you will receive, also has 3 pads for C16 to allow a box cap to be used or a wider leaded cap as per apbergs photo
The piezo buzzer can be a bit tight but can be mounted underneath or externally via wires

good luck

I'm sorry, but it still all looks OK to me.
Why do you think the PCB is incorrect?

Ahh!
We were both replying at the same time.

I see now that the query was concerning your own PCB construction, and not the correctness or otherwise of the PCB layout.

[Rov]

Dont Fool yourself with looking at the wrong post pictures,read the whole thread for these post and observe the pictures #3.we all know as to the simple error,so dont confuse the starting builders/constructors further.please.Qiaozhi.

PCB is correct, ApBergs photos are correct - my photo of my first completed board was incorrect, cap was reversed

Some color jpg's, hope they can help.....but (I am also human) if you spot a mistake please give the correction here !

In fact, it is yourself that caused all the confusion. As you can see from the above postings, ApBerg also did not understand your query, but concluded that you were questioning the integrity of the PCB. If you had simply informed Silverdog that he had inserted C15 back-to-front, it would have been much clearer, instead of questioning whether the PCB was correct. Since the -ve terminal of C15 is connected to pin 5 of the 7660, it is obvious there is no problem with the layout. Anyway, the intention behind your original query is now clear, so the case is closed.
