Wiring AION boards to use 9v Battery

[tomer629]

Recently ordered a bunch of AION PCB's during their black friday sale. Finally got all my parts ordered and got down to building the first one, the Corona (Boss OD1).

One issue. I like to power my pedals with 9v batteries, and only 9v batteries. The documentation only shows how to wire it up using a power jack, and no battery.

I have built a handful of pedals over the years. Most have only battery power but a few have battery + power jack. I figured I could figure it out referencing my old working pedals...I was wrong.


Bypass works, No sound when pedal turned on. No LED either. I am using a TRS jack for the input like all my other pedals, to cut power when unplugged.

Would be eternally grateful if someone familiar with Aion pedals could provide a wiring diagram using only a 9v battery. I have like 10 of these PCBs because I really like the the mods, board mounted pots, and documentation.

Sorry if this is a noob-ish question. I can't be the only person that prefers 9v's though. I think I wiring diagram for these PCBs would be helpful to a lot of people.



Thanks

Don't have a modified Aion Diagram but have a few links
via Google that can help you get what you desire.

The Positive from battery goes to +9v top of board and
Negative goes to Ring of TRS/Stereo Input Jack :

Ignore the 3DPT switch, shows how the battery would be hooked up :

Good Luck and Post back your results

All you have to do is connect the red wire from your battery clip to the third (unused) lug on the DC jack shown in Kevin's diagram.  You then need to substitute a stereo jack for the input and connect the black lead from the battery clip to the ring lug.  (This will disconnect your battery when you remove the input jack.)

Thanks for the replies guys.


Heavy1011:
You say "Ignore the 3DPT switch, shows how the battery would be hooked up"

I'm confused about what you mean by that. I think my problem is in the 3PDT switch. I am going to try to wire it up using the diagram you linked.


One thing I noticed about the Aion wiring diagram. The 3PDT footswitch is wired differently than all my other pedals and diagrams I've found online. Almost every diagram I've seen shows the Middle lug on the footswitch going to the Input on the board, but the Aion diagram shows this going to ground. Obviously this way of wiring it must work but I'm confused as to why its different than most other wiring diagrams. 

Please forgive my ignorance. Even after building about 5 pedals, I have always been confused by the offboard wiring.


Blue Bunny:

I am not using a DC jack at all in this build. I just ran the red wire from battery to the +9v at the top of the board. Is that wrong?

I used a 1590b encosure. It was a VERY tight fit to get a battery in there, but it does all fit. No room for a DC jack though, even if I did want that option.

I'd post a picture but I (foolishly) used the same color wire for most of my off board wiring, Thinking I'd be ok because I've built a few other pedals with no problems. 
Its a really tight fit and I routed all the wires along the side to fit the battery in, so it would be impossible to debug my wiring from a picture. ...I know...I should have used different colored wires...



Again, thanks for the help guys. Once I get it working I'll put up a wiring diagram for these Aion board using only a 9v battery, and no DC jack.

The diagram provided by Heavy1011 makes sense but it is missing one thing. A "Switch" pad on the PCB. All of my PCBs (BYOC, GGG, and Aion) have this pad. I've always kinda wondered what it does.

Edit: had wrong link

Does this just connect all the way through to the LED at the top?

If thats the case could I just not wire anything to the "switch" pad on the board. And wire my LED straight off the footswitch as shown in the diagram? (My led is right next to the footswitch anyway so that would be perfect)

[tomer629]

Just rewired as per this diagram:

Only difference is for the bottom left lug, I wired it to the "sw" pad on the PCB.


Still nothing. No light, no sound when on. Bypass works.

[heavy1011]

Sorry, should have stated to only use the battery hook up
part of the diagrams and wire up as per Aion. See now that
you do want to place your LED offboard.

The SW switch pad does switch out the LED on board the Aion PCB,
if you did use the PCB pads to mount the LED and not off board then
wire up the 3PDT switch just as Aion does along with the SW wire to Top
Middle Lug of 3PDT. Then wire rest of 3PDT just as he does.

If you do want to use LED offboard then ignore SW pad but wire Cathode
of LED to the Top Middle Lug and wire up rest of 3PDT just as Aion does
and run the Anode (positive) + 2.2/4.7k resistor to +9V pad on the PCB.
It might be tricky to get two wires into the one +9V pad.

You can see the way Aion lays out his circuits it would be better to just
use the LED pads on board the PCB. The LEDR is right there underneath
the pads for the LED. This will make wiring your Aion pedals much easier
too.

There are a couple of wiring ways to arrive @ True Bypass, like you
have seen a couple of variations. They all work the same but don't mix
and match on one single 3PDT.

Good Luck

No, it's not wrong at all.  But you still need to employ the stereo jack in order to disconnect the battery when you take out the guitar lead.  Otherwise your batteries are going to die pretty quickly.

[heavy1011]

Got to thinking about the Aion circuits and the ten
other boards that you have left to build.

Probably best to get his Micro 3PDT bypass boards
for the 3PDT switches and wire the LED right
on the board. It would make your life allot easier.

Finally got around to fixing this pedal.  Pretty sure it was actually a bad input jack that wasnt connecting the ring to sleeve when plugged in. Once I jumpered that, it worked perfectly. I installed a on/off switch to break this connection to save battery life when not in use.


Used this diagram to wire it up:

heavy1011:
Just noticed your comment about the 3PDT boards. I did get a few when I ordered the boards, but this build is really tight and it wouldn't have fit.

This picture was taken before I jumpered the ring and sleeve on the input jack, and before the on/off switch (I fit it in the empty space to the right of the 3PDT)


Sorry its huge...

tomer - that is a big pic. those jax of yours, do you have a spare one blank? I think if you put a meter on the connections, you'll find they are (probably) mono, tip/sleeve, with the extra connection a normally closed one, for breaking a connection to a speaker whhennn you inplug your headphones, like. these are not the jax you want for r/t/s power switch.

same mistake I make every time I pick those things up. there are black plastic box-jacks that comes with t/r/s AND two isolated double throw switches, just the thing for 2 battery switch arrangements.

Wow...never thought of that, thats probably whats happening. Although, if that were the case, would the LED light up when there was nothing plugged into the jack? Basically the reverse of how it normally works?

Looked around and I don't have another one of these jacks laying around to test. Oh well, pedal works now with the on/off switch so I'll leave it for now. Already excited to get started on another pedal. Even though this one sounds great btw.

there, I fixxed it.

[duck_arse]

tomer - I picked up one of these jacks today - I told you they confused me. mine is a stereo type, t/r/s, but it also has two extra switch connections, normally closed (NC) to tip, and NC to ring. if bevel is sleeve [it is], the lug either side of the bevel is the NC's, and the other 2 high-arched lugs are the ring and tip.

so this 5 lug I have can be used to switch power with the ring/sleeve, AND disconnect the battery and speaker at the same time! your camera flash has flared where I want to see, is your left hand jack 3 lug or 5? or has this box left your sight?

The ones in the pic are 3 lug (or at least the input is). I do have a bunch of those 5 lug ones though. Just Got them from Tayda. Did some testing last night and came to the same conclusion you did about them.

Plan to use them for my next few pedals. I like the enclosed body jacks as I'm usually trying to cram as much as possible in my pedals.
