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.

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.
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?
this?

and what about it? do I have the wire on the wrong one? (https://flic.kr/p/Qasxzd)
i wired it the way i wired my other boards:

F.... totally missed that!!!!!
I will try this tonight... hahaha

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

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.
^Yeah, both of those jacks are wired backwards, tip and sleeve tabs connected opposite what they should be.
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?
(https://c1.staticflickr.com/1/474/31971071576_cac03bdf87_z.jpg) (https://flic.kr/p/QHb6J1)
Yep. Backwards.
yeah just saw that... only one jack is backwards... thank you for pointing that out. sometimes when I wire these i have kids yelling in the background to help me concentrate....

I'd have to take another look, but I thought BOTH were backwards....
On the left jack (input jack), it should be GREEN to SLEEVE, GRAY to TIP.
On the right jack (output jack), it should be WHITE to TIP, SLEEVE unconnected.
cool thank you, I will double check when I get a moment...

Seconded, they are both backwards. I'll bet that makes a difference in sound getting through! ;D
so,
not working...
wired correct, and I get a pop noise, as in a pattern. when i engage the ped, the led blinks low and same pop pattern.
I still can not get pass thru.

Check to see if your jacks are shorting against the enclosure or the stomp switch when your have a cord plugged into them. It looks awfully close from the angle of the pics.
I had closed jacks before and it had the same issue. I feel it has to be a short. i will look again but I believe the jacks are not touching.

Use your multimeter for continuity.
Electrons are really really tiny. Human eyes are no good for this task.
I would not know what to check... I am still new to this... I built 2 of aion's boards before, no problems... this one just dose not like me...

Set your multimeter to continuity mode:

Then go around touching places that shouldn't be connected to each other. If the multimeter makes a noise that scares the bejaysus out of you, then they're (unexpectedly) connected. If you don't have a noisy setting like this, just put it on a resistance setting. If you get zero, then you also have continuity.
I think you have the zener diode (part no. Z1) backwards on your board. The side with the black stripe should be to the right.
I think Eric may have won the Internet this week. ;D
this guy?
one should be the opposite way correct?

No....
so which part is backwards?
Quote from: broomhandle on January 05, 2017, 06:04:23 PM

Z1. Look at the picture of the board in the build docs and find it. It's right up by the PGND pad I helped you find last time. It is orange with a black line on one end.

I see... crap. so prob can not re-use that right? pull it and get a new one? ugh...
I totally see now.. 8)

it may be still good. Assuming it has been hanging in there continually shorting your power supply, it seems to have a lot of fight in it. :icon_wink:
That diode is there for overvoltage protection. If you can be 100% certain that you won't apply more than 12V, you can leave it out.
Just remove it. It's not neede, has no effect on the sound, and protects nothing unless you are in the habit of connecting random power supplies to your 9v pedals. It's just one more thing that can go wrong.
Just wanted to say thank you to everybody for helping. As I would not have figured this out....
all working, pulled the diode, and by luck I had a spare. installed it with the stripe/pos going the correct way....
works great... now I just need a centaur decal!

You are welcome! Glad that it is working now. :icon_cool:
