finally got it built...presenting the 'TREMSHIFTER'
everything works great, i will be changing the C10 cap on the filter lfo from a 10uf to 22 or 47uf to get a nice sloooooooow sweep on the filter..
other than that i'm happy...

i used 2k-24k ldrs.
5mm super blue for ldr 1 / 5mm super green for ldr 2
and used 3mm orange for the lfo indicators....
i used 1458's but i'm sure 072's will be fine..
if you fancy building it, pcb's are available: £11.00 GBP . pm' me ok. (i only have a couple left, but have placed an order for more ok)
rob.
Ha ha! :D Brilliant video, Rob! See my comment in the member vid thread re. Petey's Soviet fuzz vid - same applies here. Pedal looks great, too. Nice knobs. (I imagine that's what the girl in the video was talking about... :icon_wink:)
Looks great Rob!
Asynchronous modulation is a beautiful thing, baby.
Nice work, Rob.
cheers guys.... 8)
off to my next project now...ahhhh its nice to have empty breadboards.....briefly... ;)
Rob I love the build it looks great. Doesn't look like your usual design it has a retro look.
This thing is...wowsers.
I'm gonna have to send you the furniture cleaning bill because I drooled all the way through that demo... :icon_twisted:
Great build, I love the dist + trem + filter sound. ;D
you mentioned you were bread boarding a tremolo , and this is right after i just slapped together an ea with " mods " :icon_mrgreen:
as always i am seriously impressed , great work sir :o gristlizer shmistlizer
now to get back to work on the time machine so i can go back , breadboard the stuff i already built in future , but then attempt to make it half as awesome as you always do . 8)
seriously , WANT pmed , i can see a few half a dozen songs materializing thru that thing , easily . especially using it with delay , i am thinking it would work very well on bass and synth as well . i may be needing a few of these things .
i may sound lover enthusiastic here but Rob , you really earned it .
:o Wow Rob! never been too keen on Trem but simply love this. Great sounds, stunning build and I nearly p****d myself watching the demo intro. Great job all round

yeah me too , thats my fav....with delay too... 8)
swapping the C10 out now...for longer sweeps... :)
the filter switch, cold be a footswich btw.. :icon_idea:
cheers guys. 8)
Sounds great Rob, very nice work :)
Not bad Rob - looks like the dog's bollocks.
Sounded like you might have been channeling some Jean Michel Jarre at about 11 min. Bet he didn't think that would be possible with a guitar and stompbox.
I don't think the development thread is really quite long enough yet, so for the deluxe version, shall we aim for envelope control and/or tap tempo?
^ cheers sam, ;D
yeah i gues we could add more n more to it just to make up the pages... :P
just stuck my phaser breadboard experiment after this...man, its the nuts...very synthy. 8)
my phaser's next on the list to build for sure... 8) 8) 8)

Rob, that's brilliant! And you made a PCB! This is why you're one of my favorite people. Well, that and the sausage pics.
Just out of curiosity, though -- did you intentionally make all the pots backwards? :)
Mind. Blown. :o

cheers john, yeah i just couldn't be bothered with ordering up reverse log pots.. its both 'rates' that are 1M log just wired in reverse. (if you want to use reverse logs, just ...erm...reverse the connections. ;D)
but i know what they do..i can live with it. :)
cheers guys. 8)
note: pcbs all gone for now.
i have ordered some more ok, should be arriving in about 2 weeks roughly . ;)

I will happily claim one of the restocked PCBs!
okey dokey brian.. 8)
Likewise count me in for one (though likely to lose this thread before it happens).
Well, the dog's bollocks it is then! Cheerio, God save the Queen and all that, and save me a board, will you Rob?
will do... 8)
I'll take a PCB, too, when they're back in.
hey i'd like to build one of these too. how do i order/pay?
That video... Are you having a laugh? Is he having a laugh? :icon_mrgreen:
Very nice pedal as always DA!
If you're taking advance orders, I'm in! That is a great demo of a great pedal!
PM'd
i swapped out/socketed my C10 last night, to a 47uf for a much slower filter sweep...sounds great. nice and smooth rise and fall...
you do lose the faster filter sweep, but i prefer the slower side of things, more phasey if you like.. 8)
of course this could be 'switched' to have both...but i'll stick with the 47uf in C10 for now...just a heads up...(so you may want to socket C10 to your own preference. )
...
i'm away for the next week or so...but as soon as i get the new batch of pcbs in i'll let you guys know ok.
cheers guys rob. 8)
You can probably get the LFO going a little faster by decreasing the value of R21 (6k8). If you make it too small, the LFO will stop oscillating though.
got mine in the mail today , thanks rob ! lookin good .
i typed up a bom , if anyone wants a copy , lemme know via pm .
Put me down for another one Rob! My postman failed me yesterday - delivering an empty envelope.
The envelope had a tear down the middle so it probably slipped out. I've reported it to the postal office so perhaps they'll find it at the bottom of the post bag or something but I might as well get a new one (and build two if I get it back!!).
I wonder if your postman is building a Tremshifter right now... :-\
This sounds amazing, now you can redo all those 1960s B movie soundtracks!
Great work, Rob. That sounds amazing :o
Any suggestions where I can score the LDR's. Ive got a smallbear basket ready for checkout but I cant find the 2-24k's
I bought some LDR's from Tayda to make some recent vactrols...
The values varied.. you can get a bunch cheap, and match them probably. ???
MC
PCB arrived in the mail today, thanks Rob!
Incidentally I've built both an ugly face and a mutron phasor II with tayda LDRs with great results. I don't have an original phasor to compare, but there was no matching going on! worth a try I reckon.
How much to ship to Canada?
Wow, great work. Super neat. Are you shipping PCBs to the states?
hi guys , firstly, i'm away from home at the moment (newcastle/benton to you northerners ;))
sadly mrs asto's lovely mum passed away on saturday a few days after we arrived up here, and we have had a lot to sort out as you can imagine.
anyway, i brought mrs astros laptop with us, and just had to buy a crappy wifi dongle, just to get online..
hopefully by the time i get home the pcbs will be delivered and ready to post out to you guys.
(postage worldwide is included in the £11.00 GBP btw ok) 8) (yes that includes canada ;))
anyway...
before i left home i quickly had to have a breadboard fix, and breadboarded a delay with the filters too, and sounded excellent, so theres another project to get my head around, i'll likely experiment with a dual VCF on it too which i breaded ages ago so know it works fine....ahhhhh too much in my head again ::) and i sorely miss my breadboards and tinkering.. :-\
but hopefully normal service should be resumed as soon as possible..
cheers guys, back soon ok. ;)
Greatest sympathies for your Mum in law Rob.
Beginning to understand your devotion to the breadboard. Got myself a stupid small one and wonder why I've not played before
cheers man,
yeah i really miss my guitar n breadboard...its gonna be 2 weeks total without a strum
or tinker arghhhhhhhhhhh...........i had to get a dongle just to remain sane...i just cant sit and watch inane shit on the tv.
it does my f.....g head in, if i hear one more ad for f....g insurance , or some girl singing along with acoustic as lamely as possible
over an advert i'll tear my own head off ....arghhhhhhhh...
anyway...breathe......................breathe......................... :)
whenever i have a clear board, i tend to try lots of the little building blocks just to refresh my head
for when i need them...then usually dive into an idea...
a TB breadboard is a must tool for anyone into sound tinkering for sure , great fun too. 8)
anyway i'll be back from my lunar mission soon... 8)
My condolences mate, to you and mrs Astro.
My condolences mate, to you and mrs Astro.
Sorry to hear about your mother in law. Prayers for the Astro family.
So sorry, Rob, condolences.

@sam: cheers man, i downloaded the spice thingy, i'll take a peek later, that tone thing is fun too.. 8)
i loaded up eagle on mrs astro's laptop (which is now my lifesaver :icon_twisted:) , and had few files/projects saved to usb stick
so i can tinker/learn a little more with that too.. 8)
tomorrow its mrs astros birthday, so im tsaking her to cragside house..which is more of a day out for me really.. ;)
http://www.yournorthumberland.co.uk/castles-historic-sites/cragside-house-and-gardens
its the grand house of a mad inventor, apparently the first house to have hydro-electricity.. lots of gadgets n stuff , .should be interesting.

Damn Rob, you did it again!
Don´t know if I will use it often, but it´s another must have.
Sounds realy psychodelic (why did I quit druging???).
Great demo also!!! Had a loud laugh this night and my wife woke up :icon_mrgreen:

Where to put the money too, I need one pcp ups, pcb?
Happy birthday mrs D too... ;D
Yo!
Happy birthday to her, happy birthday happy birthday mrs Deeheee... :icon_biggrin:

So something like the 9203 here for the photo cells , Rob? http://www.smallbearelec.com/servlet/Detail?no=711 (http://www.smallbearelec.com/servlet/Detail?no=711)
I've got it fired up and working but with the Vactrols I 'm using (Vactec VTL5C2 ) the effect is weak with both the Trem and Filter sections.
Hi john, are you using the recommended leds on page 1?.
including the 3mm sb clear orange, 5mm green,blue too.
as they will make a difference, especially on the filter...
im still not home till thursday, but i will re,measure the ldrs i used ok.
(http://static4.tme.eu/katalog_pics/8/c/9/8c91fede3c4457cc845c3d99f6686ecd/vtl5c2.jpg)
The units I'm using are these because I had them here.
I'm using orange diffused LEDs as I can't stand super brights visually.
I'll have to get my hands on some others just to get this working
and then deal with the visuals later.
My superbright 3mm's aren't really that bright...even my red on/off 3mm i stuck a 10k on, and its fine, not retina destroying at all..
but you can always diffuse them with a little rub of wet n dry..
when i tried standard diffused leds , on breadboard the effect was also weak IIRC...
ok guys i'm back from up north..been a hectic 2 weeks for me and especially mrs astro..
but all sorted now.. 8)
i'll be picking up the pcbs from post office today...and have ordered a bunch of proper jiffy bags as a couple of guys had issues with envelopes.. :)
they will be arriving on tuesday...so i'l do a blitz post out then ok.
meanwhile i'll go through the pcb requests in order to be fair and notify you ok...
due to the unforseen high number of requests i have had to order more pcbs, so if you don't get notified this week, you will when the next batch arrives ok.
cheers guys, rob
(@kevin i'll send yours out asap ok. )
ok, just had a count up in order, and ALL requests will be catered for ok guys.....
message you all later ok. 8)
I got it all working now. Sounds good.
I used Smallbear's 5mm 9203 LDRs and super bright
(water clear) Blue and Green LEDs (just like Rob said ;D) and
everything is as it should be. Thanks Rob!
Brilliant, nice one man.... 8)
did you swap c10 for a 47uf for longer filter sweeps?..
I actually like the faster bubbly sweep it gets now.
It gets pretty slow as is so I kept it to the schematic/layout.
I may even try to get the sweep faster just to see how it is.
I kind of wish I could adjust the spacing between cycles and keep
the same depth and speed. Might have to take a look at the tremulus
lune and see what's going on there.
note: all pcb orders will be sent out today ok guys.. 8)

Hey, John, you can adjust the duty cycle by varying the biasing on the oscillator's op amp - R1 and R2. Right now they provide an even split. If you lower either one, you can offset the wave. I think the Lune just turns one of them into a pot, but you could also probably stick a couple 47Ks in series with lugs 1 and 3 of a 250K pot, connect the wiper to pin 3 of the op amp, and get a pretty big range that way, even though it's a couple extra parts.
Thanks Jon. I'll look into that.
After playing with it a bit more I would also like to keep the
Speed and Depth of the filter but lessen the amount/intensity of
the filtered signal. Same rate and sweep but less of it in relation
to the clean signal. Would that be a matter of altering R11 at the first
op amp/filter stage. Less resistance I guess.
Received my pcb in the post yesterday, thanks rob
mine is runnin great , stock with tl072's . orange ( not ultra bright ) 3mm indicators , ultra blue / green leds with tayda cds cells . i did try some of the cheap EG vactrols i had , but ... they all work , they just didnt have low enough impedance , i think 40 k ish was as low as i had .
not sure about what c10 i may go stock tried ten 22 and 47 . i played thru a hacked hodad amp with a trem and delay , synching all that up , wow , i was doing that for two hours .
i did put in a 22nf instead of a 22pf .... thats what i get for not organizing my bom better , i also mis-polaritied the indicator led wires , and cut in an on/on for the cap switch , man did i do my best to screw this one up ! oh well , 11 hours later , its runnin . lol . the only mod i would think of would be adding an additional fine control pot , but , i blew my chicken salad up trying that once ... more monkey time is in order .
thanks Rob , for your work and the pcb was very nice too .

BOM for the tremshifter
(https://dl.dropboxusercontent.com/u/7464107/tremshifterBOM.jpg)
I built mine up and it sounds super. I ended up making the Filter Depth 500k instead of 100k. I did not have the spec'd photocells or LED's but came up with acceptable alternates. I tried 8002 and 9203 from SMB on the cells and ended up with 8002. For LED's, I used 3mm all around:
Trem: red diff for the indicator, clear bright for the LFO
Filter: clear bright for the indicator, one called "hyper orange" for the LFO
It's very quiet, too...not a peep of noise or ticking. Excellent work there, Rob!
Cool, glad you got it going Brian...excellent.
Was you tempted to change C10 to a 47uf for a nice slow filter sweep.?.,
I did it to mine, it sacrifices high speed, but I'm fine with That... 8)
Does anyone have any gutshots that they can post of this? I got the PCB from Rob, and am going to build this soon, but laying everything out is always the trickiest part for me.
Thanks in advance.
hi gregg..
i have this..
on my builds i take all grounds to the input jack...(tonepad wiring 5 style) i always do it this way, and have never had any pop issues whatsoever..)
(https://dl.dropboxusercontent.com/u/7464107/tremshifterpopped.jpg)
after i populated it i realised i should have put the pot wires underneath...(like i did with the leds)
Thanks Rob!
no worries.. 8)

cool....nice build, is that a 125b?
Very nice build. Love those sausage resistors. And a very clean job with the heatshrink on the LED/LDRs.
hi lagrange, little tip,
dab a little black nail varnish on the back of the exposed leds, it will stop any light pollution
affecting each ldr,
and give a stronger signal ok....rob.
Yeah, that's a 125B. Boxing took a bit of planning and a bit of trial-and-error, but it ended up fitting quite well. :)
Thank you for your nice comments, and especially for the tip about the nail varnish! This was my first time constructing my own vactrols, and I think next time I should extend the shrink tube further on the led side as well. But otherwise I'm happy how they turned out, and it was considerably easier than I initially thought. And I'll make sure to drop a little varnish on these babies! :)
Trying to use the filter section on a Tremulus Lune. The op-amp configuration is a bit a different and I'm fairly ignorant.
Tremulus' schematic is pretty easy to google. Am I having trouble with the negative feedback resistors etc. of IC1 there?
Here's my vero: (http://i.imgur.com/05EHvju.png)
It works well sounds great. I just get a pop when I use a spst to connect to IC1's pin2.
Bought the PCB. A quality designed board and now one of my favorite sounding pedals. Some really great synth-like effects with this build :icon_exclaim:
nice one rod.... 8)

Yep. Here they are. Still waiting for decals to arrive from the printshop.
The extra switch is the mod for a 10uF / 45uF cap selector with dual filter speeds.

(http://llamamusic.com/images/TremShifter_Decals_20160219.jpg)
cool, yeah i like the filter speed mod too...nice slow sweep etc...
8)
I just finished building this. I'm having a problem with the Filter LFO. The trem section works fine. The filter section won't oscillate. If I play with the rate and depth controls the filter rate LED will turn on and off. I can hear the filter effect when I do this.
I had used a BP cap for C10. I replaced this with a polarized cap with no change.
I'm using TL082s for all IC 1-3. These seem to work.
Have you tried 072's. Which i what i used.
C10 needs to be an electrolytic.
I replaced C10 with a polarized electrolytic cap. I ordered some TL072s so I'll give those a try when they get here.
I used 5mm LEDs everywhere, just those common red ones. The LEDs on the panel and the LEDs in the LDR all light up at some adjustment. Plus these LEDs are the other side of the op-amp follower so they should be isolated from the LFO sections.
Anyone want to elaborate on how this LFO works?
Solved my problem. Seems the Filter Rate pot was grounding on the case. Works pretty good. I Used some random home brew LDRs I had laying around. These work but the filter seems a little weak. I might have to experiment with different LED/LDR combos...
cool , glad you got it sorted....yes ldr values will change the response..
light to dark etc....
the leds are integral to the lfo too. i used 3mm bright oranges...
not standard diffused reds.
Can I repace the toggle switch for tone with a potentiometer?
Thanks
Thanks dude
HI ,sure you can use a 3pdt toggle switch wired up the same way.
hang on a second, i'll draw up a quick sketch ok .
back in a bit...rob . ;)
edit: done on pm... 8)
Awesome schematic, Rob!
Would it be possible to add a 'resonance' or 'mix' control for the filter by adding a pot right before the filter on/off switch, or would that also alter the voicing of the filter?
Edit: meant to say resonance, not depth :icon_rolleyes:
hi, the filter intensity is controlled by the LDR2.
you could add yet another switch, (which i avoided btw ::))
to go between a pot or the LDR2.
so the new pot becomes the same as the LDR2 but with a manual option too.
cheers rob . 8)
Hey Rob, I'm in the process of ordering parts for a Tremshifter, off the BOM.
I have a quick noob question, regarding the LDR's, as I've never worked with them before.
Is one of these okay? Or can someone point to another one?
https://www.taydaelectronics.com/photo-conductive-cell-resistor-ldr-650nm-radial-ke-10720.html
And it's just a matter of heatshrinking the led & ldr's together, I gather by the pics?
Thanks in advance.
Still got the PCB (& a wah light plate) to order as well.
Cheers,
Pete
hi pete, yes they are the ones....
they dont specify the resistance?
anyway, yes you face the led to the ldr and heatshrink.
8)
try on ebay, 10-20k to 1M.
Thanks Rob
By the power of Google, I found a data sheet for it. 10k-20k. resistance. Couldn't find one available on Smallbear.
https://www.digchip.com/datasheets/parts/datasheet/518/KE10720-pdf.php
Anything found in the stores here in Sydney are no better, and cost over $3 each. On the other hand I can grab a bunch of 20x off fleabay for $1... surely I can find a couple out of them that would do the job! haha.
yeah man, i get mine off flea bay too....cant go wrong for that price.. 8)
Oh, you do have Tremshifter PCBs in stock, do you?
yeah man.... 8)
Dumbass question here - What's the best/easiest way to match LDR's? Never worked with them before.
I'm in the process of googling, but if someone can beat me to it, I'd be grateful!
Hi! I need some help or hints :-\
I'm building this one (with an "official" pcb) and I'm having an strange problem. The thing is:
- Leds are flashing, pots working (or it seems so) and the leds for de LDR ar flashing too.
- I can't get any sound from the board, if I take out IC1 some signal is crossing, but as soon as I put again IC1 is deadly quiet. Also if I unplug the power cable I'm having again a little bit of signal.
I have double chequed continuity and some kind of shorts, haven't found anything, also tried a bunch of TL072....
¿Some sggestions? Cheers and thanks!
hows the voltages on IC1?.
pins 3/5 should have 4.5v. for bias.
make sure vol pot is up....turn speed up too....
Thanks for the quick reply Rob ;)
4,4v on both, just a little drop but it should be ok.
Also vol and speed are on the max...
It's frustrating seeing the lights flashing so cool without sound :icon_lol:
yeah, your gonna have to probe / trace through from pin 1 to pin 6/7 and see where the drop is...
which might be your LDR which is in series....from pin 1, via resistor to pin 6
is the value of that resistor ok?...R10?.
Working now!
It was just a faulty set of tl072, changed and great sounding... except I changed (not in purpouse) C5 from 1u to 1n... it was honky as hell :icon_lol:
Great sounding tremolo, really nice.
After this and Chasm Reverb working, next one will be Abductor delay II, but that's a really scary one XD
Thanks for the help!
cool glad you got it working man....
the 'dreamtime' is a les scary build... ;)
have fun. rob .
Glad I saw this. I'm having a similar issue as Salitre.
Basically it's still sitting dead on my test board since last september, Life got in the way.
Anyway, I've got a couple of extra IC's which I'll try eventually.
Finally got my tremshifter pcb functional!
Turned out to only be a dodgy soldering joint at the input.
Next is to make a purdy box for it.
Yay....its been a while ha ha...glad you got it sorted man... 8)
Last time I had touched it was just before I quit the band, so I guess there was some emotional Hangup attached to it! Haha.
I knew I'd get back to it eventually. I'll attempt an acid etch on this baby.
Cool, looking forward to seeing it.... 8)
Hey Rob, do you happen to have that drilling layout in a format other than pdf? I can never get pdfs to work properly for me.
jpg, tif, dwg, etc.
No worries if you don't. Thanks in advance.
Almost a year on, and the singer in my new band has come up with a song that fits this Tremshifter nicely! Adds that nice bit of shoegaze to the mess.
