The ground connects to the oscillation pot. The way it works is that turning the oscillation knob increases resistance between the circuit and the ground, which causes the oscillation. I'm not sure how useful the oscillation function would be to me, but I feel like the Hyperion is an all time great pedal. I love it.
There is no onboard Ground connection indeed. The Ground connection is attached to the Oscillation lug 1. The pot acts as a "ground lift" which makes the circuit oscillate and do "horrible" noises. If you want to omit it and do a regular Hyperion, the Ground connection should be at B11.
I understand! Thank you guys! So I'll take lug 1 of the oscillation pot to my 9v ground I do with my board ground on most builds.
This has been on my build list since the beginning and I don't know why it's always got pushed to the back.... Every other Devi ever build has blown my socks off
A lot of people get annoyed because it's just permutations of the same half dozen pieces, but they're missing just how radical her designs are, even if they're designed by trial and error. Most pedal builders are just tweaking old designs. I've done some measuring and stuff, and I think what's happening in several of her designs (and especially in the OK Fuzz, a very odd design) is that she is using the flipped transistors to drag the collector bias to a lower voltage, making it easier for the transistor to distort, or for the base to gate, and in other cases working as a diode to clamp the base or clip the signal. You also begin to notice that the more complicated designs are really just combinations of her earlier boost and single transistor fuzzes, as is the Hyperion. I think a lot of builders find it insulting that she would just assemble pedals from a half dozen parts, and then flip a transistor to get a new pedal, but I find the results a lot more interesting than the elaborate boutique pedals that just sound overly fussy to me. The other criticism I hear is that they 'all sound the same', which is really just labelling anything that gates in the same box without really listening to it. The OK Fuzz, for example, has different layers of signal, and if you listen closely, once the main tone dies off, you can hear a faint unaffected signal that has been there the whole time. If anything, it's just too sensitive a tone for a band setting.
Well I've got a great sounding fuzz with the oscillation pot hard left, but no oscillation, and the pot is popping the signal off and on. I tried another pot but same result. 🤷🏼♂️🤔
I did some reading and apparently the filtering cap prevents oscillation... I may just pop the circuit out as is and fit it in a two knob enclosure without the oscillation...🤔
Possibly you could tie the filter end to the true ground, but that also may not work. I think oscillation is one of the things filter caps are used to stop!
So if I fancy building another one of these and including the oscillation.... Would I just leave off the electrolytic capacitor or would I use a jumper in its place? 🤔
It has been years since I built this one, I don't know if I still have it but I have a vague memory of using a smaller value for the Osc pot, I believe it was 20kB. I don't remember if I omitted the 100uF cap, the Osc pot might work better without it.
Just don't solder a bridge in place of the 100uF cap, you'll end up with a short!
Sorry to bring up an old thread but I've just made this and wondered if you ever figured it out? The osc pot changes the tone some what but I'm wondering what its supposed to do? Also when I use the Vol knob on my guitar I get some crazy crackling? Might try a small value pot for the Osc and see what happens.
Ah fair enough. The Osc doesn't seem to do a lot so I may do the same thing. Haven't playing 1 and compared it to 2 yet, should be interesting if theres a lot of difference.
I was just about to make this and I noticed there's no ground on the layout...
ReplyDeleteI reckon I've got a 1-in 11 chance of guessing it right🤣

DeleteSo I popped it in another box and it's a Hyperion 1.

It does sound awesome.

That's so confusing to me🤣 but ok 👍👍👍

So I took out the filtering cap and changed the Osc pot for 10k, seemed to do the trick. Did anyone do something similar?
DeleteI never got this circuit to oscillate and just built the two knob version 👍
