Title: Hyper Light - the ring modulated delay pedal
Post by: BluffChill on January 13, 2018, 02:12:47 PM
Hello all! I've been devising a new circuit called the 'Hyper Light' - it's a ring modulated delay pedal. Your dry tone is clean, but the repeats are sent into a ring modulator and come back as ROBOTS.
I've had some boards made up in a prototype run and I'm looking to see what people think. Might get a run of them done, if interest is high. This is probably one for the experimental types who like glitchy weird effects like parasit studio's stuff, or Alexander, etc.

I've got a full blog post about the project here:

https://bluffchilldevices.blogspot.co.uk/ (https://bluffchilldevices.blogspot.co.uk/)

And some demos:

Enjoy, and let me know if you're interested in schematics, layouts etc.

The first demo is cool. Glitchy part sounds like a layer of it's own. Definitely interested in a schematic. I see LM567 there, that's ring-modding part. I wonder what else you can do with ring mod, octave up/down with frequency divider?

Sounds great, i'd be interested in a board if you're selling. Definitely one for the Broadcast fans.
Would be cool if the ring mod delay swept up and down. (that seems to be all i bang on about on this forum, making things sweep up and down, apologies)

I love Broadcast! Good shout. I'd also love for it to sweep up and down, and I always try and make things do that too. I have a go-to LFO which I use for it, I'll see if I can cook something up for Hyper Light v2...

Cool idea. Needs a control called 'Drift'  ;D

Is the carrier pretty high-frequency in your clips? It sounds more like an Aliaser than a Ring-Mod.

A man of fine taste!
What lfo would that be? I've been noodling around with the psycho lfo recently which i believe is based on the psuedo random lfo at geofx. Planning on hooking it up to a phaser but reckon it could work wonders with something like this

Yes it's quite high in these clips, but the 20k pot gives it quite a range. Only problem is it becomes quite audible when it's lower.

So you need a Gate for the Oscillator to counter-act bleed-through?
Title: Re: Hyper Light - the ring modulated delay pedal
Post by: BluffChill on January 14, 2018, 02:38:28 PM
Sort of - it uses the trick from the Thing Modulator where you hook it up to 9v via a 100k resistor and a big capacitor to ground, which silences it quite nicely when you're not playing.

I'd absolutely pick up a board if some become available. Very cool idea and clever to keep the dry signal, ring mods tend to oversaturate and the melody can get lost easily. Tiny part count to boot.

Awesome soundtrack! And obviously my inspiration for this.

OK so there's some interest in this circuit! I am pleased. The boards I had printed wouldn't fit a 1590B, so I have just submitted another prototype to OSHPark - should be here within 2 weeks or so. If all is well I'll get a run made. I'm in the UK but happy to ship overseas to anyone who wants one.

- ordered a prototype run of these which should be with me in the next 10 days. All being well, these will be for sale!
- had quite a few people interested in a board so if 5 people buy one, I'll post schematic so y'all can make your own because I am nice!
- I will also post a vero layout

OK folks, I got two boards, and a batch of 30 on the way, should be here within the next two weeks.

Quite a few of you have expressed an interest in a board, so if you're still interested, please send me a message - also let me know if you want to pre-order one to reserve one when the batch comes through.

The boards will be £12 including postage for UK people, or £15 for USA folk including postage (that's about $21 currently I believe)

Yay, finally got all the parts ordered and delivered. Apart from a spst switch that I thought I had  :'( Going to a local place to pick one up today, though.

In the build doc, there was a section on modding, with the following

QuoteUse an ON-OFF-ON switch and hook the extra pole up to pin 1 of the frequency pot via a 4.7k
resistor. This made the ringmod tone go mad. Might be better as a momentary stomp.

Could someone explain that again, I'm not really following. Is this to replace the existing glitch switch, or a completely separate switch that's otherwise wired to... itself? Which is the "extra pole"?

That would be in place of the glitch switch - so instead of an spst use one of those so you have that extra pole. It's just a guide - experiment, go crazy! Hope you enjoy it :)

Finally got this one boxed up today, have been waiting on Tayda for what seems like forever. Had a few issues initially which Bluff kindly helped me work through. He even sent me a new board when we couldn't get anything out of the first one.  I added a psuedo random lfo through a trannie on a dpdt switch to vary the resistance on the delay pot or the frequency pot. Makes for ever more demented bleepy bloopy goodness. Super cool!

It's the guy in the middle with all the mis-matched knobs.
(https://s14.postimg.org/50mszteml/Pedalboard_2018.jpg) (https://postimg.org/image/50mszteml/)


Here's a sound clip. Just recoded through a phone so not amazing but you get the idea. I started with the freq. pot all the way up so the carrier signal is inaudible and you get the hear to random lfo at work. The mix is pretty much maxed throughout, the carrier isn't that prominent when the mix is dialled back.

I think it's the delay being modulated at the beginning of the clip, then it switches to the freq. The glide pot is being adjusted periodically so sometimes it's a glitchy, jumpy lfo and other times a nice smooth sweep.

https://soundcloud.com/user-418904944/ring-mod-psycho-lfo

It's a great circuit to start with and really good fun to mess around with. I'd thoroughly recommend it!
Title: Re: Hyper Light - the ring modulated delay pedal
Post by: patrick398 on March 19, 2018, 11:02:57 AM
Also, the only switch i had was a centre on and i was too lazy to go and buy a centre off one. That means that the freq pot is wired to the top of the switch, the delay to the bottom, and because the middle position is making some connections i didn't even both to work out it makes some brutal white noise...which obviously i love.
Probably should have recorded that too...
Title: Re: Hyper Light - the ring modulated delay pedal
Post by: ~arph on March 19, 2018, 11:27:36 AM
Hey man, that sounds fantastic! so the LFO is set up it can modulate either Delay or Freq? or both? EDIT: I must learn to read  ;)
I like it, maybe I'm going to try something like this too, but then with the clari(not) as a starting point, I like envelope modulation

Hey, your board should work fine - just one thing though, Patrick had more luck using a 1k resistor from 9v to LM567 V+ than 9V. I think it depends on the LM567CN you have. Mine works fine with 100k, so I'd be interested to hear more people's experience with it!

Yeah that was a weird one, took ages to debug. I only twigged after breadboarding a simple 567 noise circuit to check the ICs and noticed that it had 9v going straight in. On my hyper light board the 567 was only getting 0.1v or something. For me it wouldn't work with anything above 1k, not even 1k5.

Well I finally got to the board and built it, and mine definitely wouldn't run with a 100k at R7.  I put in a 2k trimmer, the delay works when the voltage to the 567 is 9v, but you have to crank it down to about 5 before the ring mod kicks in.  My build has an ever present high pitched whistle that goes up in down with the frequency knob, and is changed by altering the voltage to the 567 with the trimmer.  Is this just the carrier ? Is there any way to mitigate it at all? I didn't hear this in either of the demos on this thread.  I tried about 6 different 567s and they all whistle.  .. anyway it's pretty rad and I'm having fun with it.  Any recommendations on how to do modulation? I mean what type of circuit ?
Title: Re: Hyper Light - the ring modulated delay pedal
Post by: patrick398 on April 17, 2018, 05:29:20 AM
Mine wouldn't work with anything other than a 1k. The whistle is normal i think, it's the carrier, though turning the frequency all the way up should make it inaudible but then you're left with just delay. EDIT: Just re-read your post, are you only able to get either delay or ring mod, not both?

For modulation I put an LFO on a switch to the delay pot and the frequency pot so i can select which one is modulated. Ordinarily you'd want to have a switch that bypasses the delay pot and puts the LFO between pins 6 and 3/4 if i remember correctly.
Look at the  schem for the echo base:

(https://s17.postimg.cc/3wjzwb423/echo_base_schem.png) (https://postimg.cc/image/3wjzwb423/)

I used a pseudo random lfo for mine but the principal of LFO into transistor as variable resistor to the pt2399 is the same
Title: Re: Hyper Light - the ring modulated delay pedal
Post by: BetterOffShred on April 17, 2018, 10:00:16 AM
I am able to get both at the same time, but it depends on how much voltage is going to the LM567.  Around 1k as you indicated everything works.   :)   I will probably just put a 1k in there, that's what I'm dialing in on my trimmer anyway.   

I had the LFO from  Paul in the lab for the nintendetar built up, so I hooked it up to the frequency pot, and it didn't really do anything on either side that I could tell.  I hooked it up to the time pot, and it didn't really do anything, but if I turn the time pot almost all the way up, there is a sweet spot where it definitely is modulating the time.   I guess I need to understand the LFO portion of that schematic you linked.   I would need to run my LFO into a PNP as shown I guess..   I have a ken stone psycho LFO laying around too, that might be fun to try.   

Another option is to put an LDR in parallel with the time/freq pot, and then have the LFO drive a LED maybe?   I know it works on the logan 5...

Speaking of Logan 5.. (Dino has a build doc with schematic in the gallery) it looks like it's using a 100k resistor on the V+ path in series with a trimmer as well.. so I'm curious as to why both of our builds simply would not ring at 100k. .   The datasheet for these chips shows operational voltage between 3.5 and 8.5V, so I'm curious.. I may breadboard the Logan 5 and see what's happening there with 100k supply resistor.  .. -Brett

I can't get anything out of soundcloud, at any time, so I still haven't heard this working - but - I was messing with an "LM567" in a similar circuit, and it didn't sound like anything except a really annoying carrier tone. but, the spec sheet says the "LMC567", the cmos version of the chip, runs at twice the freq of the LM567, so maybe that's why I'm underwhelmed.

B.O.S. - are you using the cmos version? the LM567 is also meant to run at or below 5V supply, not 9V.

Pretty sure the Logan 5 has been scrubbed from the net for copyright reasons. I have a copy of the scheme I can send you when I get home.

I will also provide the board with the exact model number of the 567 I use. I have bought some others recently and have the same problems when not using my original model, so I'm going back to the drawing board and will keep you all updated!

Thanks all for your continued interest in this. Boards still available if anyone wants one!

I can't get anything out of soundcloud, at any time, so I still haven't heard this working - but - I was messing with an "LM567" in a similar circuit, and it didn't sound like anything except a really annoying carrier tone. but, the spec sheet says the "LMC567", the cmos version of the chip, runs at twice the freq of the LM567, so maybe that's why I'm underwhelmed.

B.O.S. - are you using the cmos version? the LM567 is also meant to run at or below 5V supply, not 9V.
I am using a LM567CN, section 8.2 of the TI datasheet, Vcc Supply Voltage  Min 3.5V Max 8.5V
Mine does lots of ring mod, and the frequency works fine.  I think the board is actually operating correctly it does ring mod repeats, and you can change the delay characteristics with those controls.  The mix works fine too, though all the way up it seems to run away regardless of feedback knob position.

No I am not using the Cmos version.   I am using the LM567CN from Tayda.
See section 8.2 of the datasheet.. That's where I was getting my voltage figures.   
ALso there's a build doc in the gallery under Dino's stuff for the Logan 5, it's a PDF and has the schematic. 
Im curious about the operation of this chip though, reading through the build doc for the Logan 5, it indicates that you tweak the voltage trimmer that's parallel with the 100k (R7 in the Hyperlight) to find a sweet spot for carrier noise and max volume.  As I indicated earlier, I was definitely able to change the noise level of the carrier with my trimmer, though I had to use the 2k and that's it.. not 100K + another 100K trimmer..  I'd like to get to the bottom of this :)
thanks for looking fellas, and thanks again for the board Bluff.  It's pretty fun

I guess we need to know what Bluff built/designed his with.. LMC567, or LM567C  :icon_mrgreen:

I'll keep fooling around with the modulation!

OK, these are the LMC567CNs I used originally - I bought about 8 of these and sold them with kits and now have none left! They're also no longer stocked on Farnell:
http://uk.farnell.com/webapp/wcs/stores/servlet/ProductDisplay?catalogId=10001&langId=44&urlRequestType=Base&partNumber=2496237&storeId=10151 (http://uk.farnell.com/webapp/wcs/stores/servlet/ProductDisplay?catalogId=10001&langId=44&urlRequestType=Base&partNumber=2496237&storeId=10151)

You might be able to find some others elsewhere. I'm going to re-breadboard the entire thing and see what I can do. I'll keep you posted!

I bet that right there is the difference!  Lower current draw, same resistance..  :)   I will see if I can Ebay up a couple.. Mouser only has the SMD joints. 
http://www.ti.com/lit/ds/symlink/lmc567.pdf
Section 9.4.1 has the previsions to substitute the LMC567 for a LM567C, some cap changes, so I suppose I could just do these backwards to the circuit..
Title: Re: Hyper Light - the ring modulated delay pedal
Post by: BluffChill on April 17, 2018, 04:19:50 PM
Yep, never even realised that was what it was! Bought them thinking they were regular old LM567. I will crack on!

I found a batch of LMC567 on eBay and rolled the dice. I hope they work.  I've had pretty good luck with eBay chips.. knock on wood.  May be a couple weeks till they arrive.  I'll report back. :)
Title: Re: Hyper Light - the ring modulated delay pedal
Post by: BluffChill on May 03, 2018, 06:46:11 PM
Well, it looks like the LMC567 is now OBSOLETE! Except in SMD format. So I'm considering for the next version doing it surface mount, as an LM567 is absolutely worthless as a substitute due to insane carrier bleed.

Is there much call for stuff with SMT components around these parts? I could solder them all on myself and continue selling if people are still interested.

Anyway I've started redesigning the HyperLight to be a bit clearer (but still lo-fi) and noticed I've run out of LMC567s, so I've ordered a single one off eBay at a ridiculous price and will continue to prototype this one. Sold several on eBay this week so there's clearly still interest out there in weird ring-mod-noisy-lo-fi-land!

I got a bag of LMC567 from china coming, but they may all be counterfeit..   I'll let you know when I get them.   

Yeah I personally would pay extra to have the right chip on an SMT adapter board come with it.   I mean not like $50 USD or anything, but as long as it's reasonable I would think that you'd probably sell them all with a chip.    It's a pretty cool effect, and I like the sounds I was getting even with the insane carrier bleed (which at the time I thought was something else because it was so pronounced compared to any carrier bleed I've heard on my other ring mod stuff).   I'll probably have to revisit that 100K 9V load resistor to the 567 chip if the ones I get are good to go, but it's built and waiting for a chip :)   

Thankss Bluff :)

I'd be interested in building this if you can sell the board with the pre-populated smd 567 chip!
Title: Re: Hyper Light - the ring modulated delay pedal
Post by: BetterOffShred on May 07, 2018, 07:10:20 PM
 My Chinese LMC567's came in so I put in a 100k trimmer for the 567 supply and popped a new chip in... And... andddddd...

Yeah it works great.  Sounds dope as hell and no noise.  Imagine that ;)  I can name the supplier of Chinese chips if anyone wants to get a bag.   

So yeah now I'm going to finish the modulation mod, and I'm thinking the glitch switch will be on a momentary on the box.  It swells cool if you hold it down and then release.

Thanks for the feedback guys! Shred I'm glad you had success and like the pedal. I'm going to attempt to source some Chinese LMCs cheap.

Failing that, I've just about finished up v2, which is a slight improvement, shouldn't have the impedance problems that patrick had, and will have SMD already installed (precision soldering iron was a good choice)

I've just finished breadboarding, and will let you know how it goes!

Shred, I'd be grateful to hear the name of the Chinese supplier too.

I got 5 for about 10$ USD from "allenlu1995"   I have only tried 2, but they both work.  :)

Also I want a V2.0 board ;) let us know when they are ready.  Can never have too many delays.
Title: Re: Hyper Light - the ring modulated delay pedal
Post by: BluffChill on May 17, 2018, 06:03:36 PM
Thanks Shred.
I pulled the trigger on some Chinese ones, they arrived today (batch of 10 for $7USD!) and they work! They're not as good as the $4 single one I got on eBay - not quite as much volume with all the same resistance values etc, but damn it does the trick.

Also I've just completed a painstaking recreation of the circuit from scratch, with better feedback control (no self oscillation though - it never worked that well on version 1), cleaner but still lo-fi repeats, and an improved, external mix switch so you can dial in as much ringmod you want. Oh and also. Almost no carrier bleed :)

The result will be a 1590BB board and I'll be sending off for a prototype run very shortly.

Bluffchill, sounds great, I'd be interested in building it!

BTW, could it be set up with a momentary max-feedback switch? I'm thinking a momentary that just sends all the output back to the input or perhaps just shorts the feedback pot? I'd love to be able to use it to get short bursts of maximal oscillation.

Yes it absolutely could - just whack a 2.2M resistor between (I think) pins 12 and 16.

OK! HyperLight v2 is on its way for fabrication.
Made a bunch of tweaks to it, you can read about them here:

bluff was kind enough to send me a board, which i popped last nite. i gotta gig tonite so probably can't get back to it til tomorrow...

went with 16mm board mounted pots (and 100k for the delay time, i used cut offs from some 1n4007's to jump the board to that one pot cuz i was out of board mount 100k's) and made r7 a 100k trimmer so hopefully will be able to dial it in once its all done.

i mounted the big electro to the bottom of the board <handy trick when ya wanna squeeze 10lbs of shite into an 8 lb sock> which gave me a space to lay the voltage reg over... i should be able to just about squeeze it into a 1590b i think.

nice project, hopefully i gotta couple more 2399's kicking around, i had a bunch but i think most are stuck in latchup.

anyways...

Hyper Light v2 prototype boards are IN!!

I'll be testing these tomorrow or Sunday. All being well, you can hit me up if you want one.

It's finished!!

Gonna order a batch of PCBs for this tomorrow, let me know if you want one and we could sort out a preorder or something.

you are a sick young man. i appreciate that!!
sounds great bluff! i diggit!
waiting on a slow boat from china for some boxes to finish mine, which is working and sounds killer. weird and cozmik and
very psychedelic!

but a thought occurred to me, as it often does when watching these things...

did ya ever think about separating it out so you can either have an effects loop for the dry signal?

or maybe stereo outs so you could split them somehow? i just think a raging fuzz with the ring mod'd repeats in stereo would be incredible, and ya could process both the dry and hyperlight signals further down the road separately.

above my paygrade, but maybe an idea for a mod or the hyper light mk 3?

killer, bro  :icon_mrgreen:

Glad to hear you're enjoying yours!!

Splitting the signal might not actually be that difficult - I think all I'd need is a switching jack.
