Aion Refractor Klon Clone help

[broomhandle]

Hello,

new to the forum. I have built an Aion Klon and I am having some issues. I can not get it to pass thru. And when engagged, it pops and the LED blinks with a very low light.

I feel it has to be a short, I thought maybe jacks, so I swapped them, and it has the same issue.

I have built 3 other Aion with no issues, this has to be something dumb I have done...

Welcome to the forum!

Looking at your board:
Empty PGND pad?

Look at the back of the board for shorts, also reflow all of your solder joints, just looking at the diodes, you shouldn't be able to see through the board.

PGND pad?

Hi there.

The debugging instructiosn are stickied in the header under your forum profile picture:

http://www.diystompboxes.com/wiki/index.php?title=Debugging

Please follow the instructions (including those in the link to RG Keen's debugging page on Geofex) as they are a systematic process that will help debug any project.

If you want a slightly abridged version, we need voltages, audio probe results, and photos of both sides of the board to be able to do more than guess.

PGND pad?

Yes, your Power Ground pad at the top of the board by the LED.

I have checked for shorts, I do not see anything. that was my 1st thought. as for the diodes. they are clear, I dont understand...

The solder should flow through the board to the pad on the top side, your solder joints for your diodes don't do this, and it's understandable, they are harder to solder.

Yes, your Power Ground pad at the top of the board by the LED.

No, I mean the actual empty pad on the PCB very close to that that does not have a wire connected to it.  It is labeled PGND.

[broomhandle]

sorry for being daft.

so for the diodes they need to be removed and new ones? but space so they do not touch the board?

and on the pgnd, are you taking about that empty soilder tab?

[broomhandle]

this?



and what about it? do I have the wire on the wrong one?

[broomhandle]

i wired it the way i wired my other boards:

[EBK]

This.  Your ground from your DC jack should connect to this.

[broomhandle]

F.... totally missed that!!!!!

I will try this tonight... hahaha

[EBK]

F.... totally missed that!!!!!

Several times, it seems.   
It's OK.  Let us know your results once you get that soldered.

[duck_arse]

can I ask - is the grey wire on the left-most jack connecting the jack sleeve to the board signal in? if yes - is there a chance the right-most jack has only the white wire connecting only the sleeve, with no tip connection? and yes, I realise you've switched your jacks, any chance that same mistake has carried over?

have you checked with the multimeter for connection between the board input (or output) and the tip connections of a cable plugged into each jack?

[edit :] noticed I'd wired my questtion backwards as well.

[thermionix]

^Yeah, both of those jacks are wired backwards, tip and sleeve tabs connected opposite what they should be.

[broomhandle]

are they wired backwards?

i got everything wired up and all it does is feedback.

do the wires on the jacks need to be swapped?

[EBK]

Yep. Backwards.
