Perhaps the reliable source could arrange for Perrow to PM me his address?

I will talk to him and see if that can be arranged.

Manny, I understand you used the NE555, what were the issues?
I can see in the thread you had some problems with the timer, did you eventually resolve them for both modes?

Thanks!  :)

Hi Magnus,

Initially, the NE555 just got extremely hot until I added some resistance before the LEDs on the output pin.
There is a crude hand drawn layout a few pages back that I posted. That's the version that I used and it worked a treat with both versions of the chip.

Note that there is a small error on the drawing (one ground symbol too many on the left). Check the posts that follow it where I point it out.

 :)

Hi Guys,

Mark's boards arrived through the post today, and they look great!

Perrow, when I looked at the layout I knew it was small but not this small!

Here's a pic to put it into perspective:



PS: Brits, I would have used a 50p but I didn't want to freak anyone out with an equilaterally curved heptagonal coin.  :icon_wink:

ha ha..the 50p confusion... :icon_mrgreen:

wow that was quick!.... :o


get yourselves ready for the 'super miniscule amoebic trem'. :icon_mrgreen:. coming soon--ish!..

Should give a nice Square Wave from what's been transpiring in that thread.

right ok guys, ive just tried this 'negistor'..(super miniscule amoebic trem ha ha)...and yay! it does work...and no click when its running...!!!!!....which is f====g excellent!
even with my mixer level full on...there is no noise at all..yayyyyyyy....even with the bleed depth....when not playing....yayyyyyyyyyyy...........
yayyyyyyyyyyyyyyyyyy.....but...

its is clicking when i play only... boooooo boooooooo. :-\....through the depth ground when turned off/full trem etc.....needs a bit of tinkering. :icon_rolleyes:

I don't even think I realize how small that board is. Just looking at your photo made me think, well a dil-8 plus one high, and just over double that wide. That means the board is just (equivalently) large enough to house three opamps with one row of connectors  :icon_eek:

hi guys, been messing around with this 'negistor' tiny miniscule amoeba trem...heres a clip..

at the end i turn my mixer gain up full...no click...whooooo....added a quick depth pot too...still tinkering...but with good results..and no 555...whooooo.... :icon_twisted:

http://dl.dropbox.com/u/7464107/negistortrem.mp3

even smaller than tiny trem...the only issue i can foresee is what manny and me had with 'fussy' transistors...2n2222a's other than that cool......... 8)

schemo soon!...for those interested. :icon_wink:

schemo: of the soundclip....

http://dl.dropbox.com/u/7464107/tiny%20miniscule%20amoeba%20tremolo.pdf

heres a vero too... 8) f==k ive been busy today.....one day i'll create a 1 component pedal... :icon_eek:

special thanks go to armando.... :icon_cool:

This circuit absolutely blows my mind. It took me like 15 minutes to realize how the dang thing works when the two parts of the circuit aren't connected (apparently I fail and reading LDR as light dependent resistor ;D). Cool concept bro.

cheers jace, yeah i love the little circuits that do a lot....crazy little bugger eh!... :icon_mrgreen:


edit: im running 2 leds off it too...red for the ldr and a green one for the rate indicator...the green one doesn't drain the arse out of the red one ok.... :icon_wink:

edit: f==k i just noticed my posts number....the 555...arghhhhhhhhhhhhhhhhh..its haunting me!... :icon_eek:

Here's my contribution to this topic, a PCB layout for anyone who wants it.

I almost added a spot in there for another LED. From your other projects you seem to be in love with the rate LED idea.  ;D

nice one man...excellent, rapid work.... :icon_eek:

yeah i love an led or 2..or 20 ...its good to see the speed of it before you click it on.....thats my excuse anyway... :icon_mrgreen:

i think it may need a bit more tinkering on it before i commit it to a pcb as yet....theres a tiny bit of crackle when on rythm pickup, gotta sort that out..
but overall i prefer it to the annoying 555.....if you listen closely to the clip it is there....i think i need to up the resistor a bit on the led or something...

i think perrow,manny ,and above all mark, will be a bit pissed that they have pcb's for the 'tiny trem' now.....sorry guys...progress n all that stuff!... :icon_wink:

Jace,

One suggestion: Put the electro pads close together. That way you can push it in without having to bend the leads in funny ways, and it'll also be more stable.

Hopefully I can find a few minutes this week to perf it together... Thanks for the quick layout

I'll make a new one I'm sure. I'll just until Rob decides on his final product. Thanks for the suggestion.

Unable to leave well enough alone, I decided to jump into this spirit of as small as we can get it and redid the layout. I also added in a spot for a rate LED (the green one).

The amoebic trem is looking very cool Rob.
I'm waiting for some more 2N2222A's to try this with.

So I think we've at least discovered that it's the LDR causing the tick and not the 555...

I'm waiting for a 1590A to arrive so I can get started with one of Mark's boards.

Also, I think we've discovered a sort of Moore's Law of stompboxes, I think it should be named "Rob's Law" and could be expressed as:
"Every 10 posts, Rob's circuits will lose a component"
 ;D

hi manny , 'robs law' ha ha...

ive got it down to 1 resistor now!....... :icon_mrgreen:

but seriously, there is no 'ticking' at all....its more of an led/ldr resistance whack ya guitar and it crackles type of sound......(great description eh?)

changing the 100r off the led to ground to 1k say, dramatically changes/slows  the speed rate range for example...

i cant wait till some of you guys get ya bits and experiment too...this bugger 'will' be nailed......with no noises...eventually...

but im impressed with it so far....no clicking on full gain etc..........tweak...tweak..... :icon_wink:


@jace: green led  :icon_mrgreen:

Found a mistake with my pcb layout. Ignore my last post. Here's the corrected layout.
