Title: is that a wrong wiring?
Post by: venom02 on March 30, 2013, 07:53:06 AM
Hi everyone. I'm trying to build a devi ever Hyperion 2 clone but it doesnt work well. i'm getting a continuous loud signal as output and the guitar seems doesnt effect it.

here's the board schematic

(http://1.bp.blogspot.com/-n6s2V6TheHQ/UPKxH7_2PoI/AAAAAAAAEKA/U8bxUbZnTKw/s1600/Devi+Ever+Hyperion+2.png)

and here's how i wired it offboard (its ugly but i hope clear to read)

(omitted the 2,2k res soldered to the LED)

I triple-checked the board and it's correct. where could it be the problem? many thanks

Check for solder bridges around the cuts and between the strips

checked and nothing is bridging. here's a pic, the marks between strips are cutter passages to be sure the is nothing between.

the problem is still there: a loud sound modulated by the INT pot while the volume and OSC pots seems do nothing or very little.

If not powered on the guitar sound is pretty and clear (so the bypass is working well)

Perhaps i'm wrong, but, that looks like a bridge to me..

I circled the bit in Red.

Good Luck

no that solder is not touching the strip beneath. its just the view angle of the picture that makes an illusion ;)

Ok so, what type of loud signal, and are you getting any guitar sound at all?
Also, your dc jack doesn't appear to be grounded to your input jack

You have grounded oscillation 1 not 3 ;) hope this helps

uhm now i see you're right, my DC jack is not grounded to Input, thanks. i will fix it and thell if that has resolved the problem.

that will only change the rotation of the pot from clockwise to counterclockwise ;)

well, still not resolved the issue. now i the VOL pot seems to work correctly but the noise hasn't gone and the guitar is not hearable almost at all as before

now the wiring is this, addedo ground IN to ground DC

look up the mbp standard wiring pdf, it's what we all use pretty much, edit, here it is I found it.

Checked using your PDF but it seems exactly like my wiring diagram :(

Just to be pedantic... the image in the OP is NOT a schematic, it's a layout.

Except you have a volume lug hooked to the stomp. That's a strange layout for sure. I'm still trying to figure it out myself. Also osc 3 should go to ground and you have 1 going to ground.

^The in's and out's of the board run through the pots so according to the layout that seems to be right...

I see,I'm looking at it now. osc 3 should go to ground and you have 1 going to ground. I've never seen a layout quite like that. If you're using a metal enclosure,you don't necessarily have to ground the output jack either. I was looking over on tagboard. They mentioned a 100uf cap you should omit as well. This is an impressive layout to tackle.

regarding OSC 3 and 1: i saw in the project's page that the designer admitted to grounding osc 1 instead osc 3 to invert the direction of the pot (from anticlockwise to clockwise) that should not be the source of the problem.

Yeah, I don't know then, that's a mystery for sure. Time to make an audio probe and see where the signal stops or if it's getting in at all.

I finally got the problem. it seems an uncomplete solder on the board (2nd row from the bottom, right next to the hole)

thanks everyone for the support, you are definitely the best DIY community on the web ;)

Great news! How does it sound?

Awesome! I had just ordered parts to build 2 hyperion version 1's based off this same layout. Curious how you like it as well, does it compare pretty well the the pgs demo video?
Title: Re: is that a wrong wiring?
Post by: venom02 on April 01, 2013, 03:08:25 PM
it sound great and very close to the actual demo. it's very odd how to use the OSC pot, but is like she uses it in the video ;)
