Hyper Light - the ring modulated delay pedal

[BetterOffShred]

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.

[BluffChill]

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!

[BetterOffShred]

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!

[BetterOffShred]

 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. 

[BluffChill]

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.

[BluffChill]

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.

[BetterOffShred]

You know I'm down for one when they're ready    it all sounds cool as hell. Let me know!! I wannit

[cnspedalbuilder]

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.

[BluffChill]

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

[BluffChill]

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

Sick!     when do you expect them?  And can I buy one 

[pinkjimiphoton]

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...

[BluffChill]

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.

[BluffChill]

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 

[BluffChill]

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.
