tiny tremoloOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO

It's losing family, nothing different except these little guys never once f*cked you over. 
We've got three cats right now, all around ten years old. Hopefully they'll go on until they're 20 *fingers crossed*

so true,for those very reasons...not ever @#$%ing me over,no arguing, no demands, except a bit of food and a stroke etc, he was a great calming influence and company....

we have a fat old tabby girl too ' gertrude'...she seems a little lost too at the moment....

hope yours stay safe n well ...

[mrsuspend]

Thanks, they're hibernating in our flat, waiting for spring and the countryside.
I guess cats are sort of like tiny tremolos but maybe we should get back on topic... 

[deadastronaut]

yep!...ok back on topic...


has anyone tried the 0.01uf /10nf cap pin 5 to ground..and pin 4 to v...? if not i'll give it a go today...

[Perrow]

cheers guys...

he didnt make it....poor old fella...me and my missus cried like babies when he passed on......very upsetting...

@perrow, 16 yeah. he had a good innings, we had him from a kitten, he had a great character and will be sorely missed...

we planted a flowering evergreen today in his honour...r.i.p. 'cooney boy'......

Know the feeling.

Will we see a memorial pedal?

[vendettav]

can anybody give me a russian name for LDR??? the stores here in Armenia work in russian or armenian.. didnt know what LDR means...
or can anybody help me with wiring a transistor as a switch to kill the signal??

[mrsuspend]

Maybe you could look for photocell resistor or something similar?

[deadastronaut]

@perrow...no, i wouldnt go that far!...might etch him a little plaque though!..


@vendetta...as magnus suggested.. (say it with a russian accent though!)

no idea on the tranny switch.......


tried the 10nf on pin 5 to -  and pin 4 to pin 8...works ok....no retriggering needed...

but i had no clicking in the first place anyway..


just for the hell of it here it is breadboarded...

I'm so sorry about your cat Rob!

Is this last mod to fix the clicking?

[deadastronaut]

thanks man...

it may do.....and any retriggering problems people may have...

i honestly dont have any ticking on mine without the mod though....i have it on my breadboard now , and it behaves really well...going for hours...

the only issue i ever had with ticking was when i tried using superbright leds...they made it noisey as hell..i changed them to standard leds..5mm/3mm .and it sorted it.........

the only other cure was the 9v > 2.2k > pin 8..

checkout the breadboard pdf on my last post....thats exactly how i have it...^^^^^^

[Der Groovemeister]

Rob, there's probably something wrong with your dropbox, cause i can't download the pdf. Nothing happens.

[deadastronaut]

it works for me...ill try again ok....anyone else having problems seeing it?

Sorry, my fault. In some bizarre way i can't  download it on one pc, but on my other pc i can... WTF???

Edit: googled: if i put ?dl=1 at the end of the url it works.

[pazuzu]

wow, this is cool. this is the first time i come in here (this thread). i am going to build this tonight.

by the way deadastronaut, how did you come to hanging out here at this forum? i remember i remember commenting on your lm386 distortion video on youtube waaay back telling you to come here, or were you already on at that point?

[Der Groovemeister]

Rob, I tried your last mods, but nothing changed to the ticking. Or should i remove the pin 4-5 connection? When i connected pin 4-5 (still connected) with pin 8 it blinked half tempo. This could be a cool feature on a stompswitch!  ;DI believe the Schaller trem had that too and the Fulltone Supatrem.
Still ticking though...

They did have double/half speed features, but neither used the 555 chip nor implemented anything remotely close to the way this circuit is. Just a point of note. the supatrem parallels the other half of the dual gang rate pot to half the resistance and instantly double the rate.

[Der Groovemeister]

I know they're totally different designs. Could connecting 4,5 and 8 harm the 555 though? Otherwise i'm including it in my build. You can get a cool effect if you hold a chord and press the switch  to double the speed for one bar or so 

[deadastronaut]

@pazuzu..man that was a while back now!...i remember someone on here sending me an email, saying that one of my projects were being discussed...and would i care to join in..so i did!..and have been on here ever since.. .


@servaas, i really cant see how your getting ticking still?...ive built 4 of these with no problems at all...(unboxed too)......the only thing i can think of ,is it may be your ldr's value...have you tried a different one?..

also what led for the ldr are you using?...

i noticed the speed rate difference with the pin 5 off....but  i wouldnt do that or it might not want to start/retrigger again.. ...

thats the only reason i connected 4-5 together was because of that power on triggering problem...

[Der Groovemeister]

I will desolder the LDR and check if it still ticks... The led for the LDR is a normal red 5mm. I tried a low current one, but that ticked too. I tried disconnecting the indicator led (normal red 3mm) but also no change. It seemed to tick less loud when i had the led resistors connected, but then the depth was less, due to less brightness of the led.

Am i the only one who experiences ticking in this project???

[deadastronaut]

your probabaly not the only one..lots of people had this problem before the 2.2k power tweak....

did you end up trying a pot from the 9v to the pin8 to see if you could lower the voltage to stop any clicking...im just thinking that the 'tolerance' on your ic may be slighlty different...

'tolerance on even the 2.2k may be an issue too...just a thought.

if it was going to tick it would definately do it without the depth pot...and just a wire from the ldr to ground...this is how i have it at the moment and its fine..

funny i bought some ldr's from a guy in holland recently off ebay...and they are fine too...

as an experiment today i wired 3 hi bright 5m leds off the 3 pin to ground..and had the normal hi bright red for ldr..and it still doesnt tick..i though it would.....but no!.

the only time it ticks is when i connect pin8 directly to 9v...so i would tinker with that 2.2k area with a pot if anything...

tell you what i'll do...

i'll post all my pin voltages ok.....and we can see whats happening from there ok...see if there are any major differences...i'm using a 9v psu daisy chain type by the way..not a battery..


i turned the speed rate full so i could get a steady measurement ok...ts555cn.

pin 1 = 0.00
pin2 =1.13v
pin3 =1.5v
pin4 =1.43v
pin5 =1.43v  (4-5 connected)
pin6 =1.13v
pin7 =1.13v
pin8 =2.19v

my psu puts out 9.11volts.

my 2.2k is actually 2.17k...(due to tolerance etc)

my 47uf is a 16v model
