Phil beat me to it

aha...cool...cheers guys.

Back on my computer. Yay! Anyway, after checking out Phil's picture (didn't have my blackberry set up to view them) That's the smarter way to wire up that bad boy to a dpdt. So just ignore what I put haha.

deadastronaut · January 30, 2011, 11:05:16 PM

ok, cheers man,.

heres a clip of it in action....nice n smooth..

http://dl.dropbox.com/u/7464107/trem1wav.wav..

right i'll go with phils.(cheers phil )..but with another led for on /off...not using the rate led as on/off..though.

phector2004 · January 30, 2011, 11:13:08 PM

Enjoy!

Does this absolutely need a CMOS555? Only got one left...

deadastronaut · January 30, 2011, 11:18:30 PM

i would use one...

some have been ok with a normal 555, some got really hot though!..but that was when 9v was running it....socket it i guess...

p.s on that diagram, where does my in tip...and out tip go....to the board in/out?..sorry mate, just still dont get it..

Nice man.

I'm too lazy to make a diagram, but keep a LED in parallel with your LDR LED will get you your rate LED.

Then, wire it as such:

1 2
3 4
5 6

1 is the input/output of your effect, 2 is the negative side of your on/off LED, with the positive side going to the DC jack, 3 goes to the in and out tips of your jacks, 4 goes to ground, and 5/6 are not connected. Bingo!

deadastronaut · January 30, 2011, 11:23:12 PM

whoooooo.....cheers jace, i'll give it a go.....whooooooo.......

bingo, full house!...

the 3mm led on the board is the rate led..that will go in the top of the box...always on

so theres 2 leds on the box , speed, and on/off...coz i'm greedy...

like this?

Jhouse · January 30, 2011, 11:55:58 PM

Looks legit to me.

deadastronaut · January 30, 2011, 11:58:15 PM

cool. as long as i put a resistor on the led neg..

i'll tidy it up now then..

Jhouse · January 31, 2011, 12:03:55 AM

The positive leg of the led gets the resistor.

i always whack em on the neg...even on breadboard!..hmmmm..

as in..

anyway, im off to bed..its 5:10am...here......

cheers man, rob.

Jhouse · January 31, 2011, 12:14:54 AM

Hmm. I've never seen anyone do it like that. Well, if it works, it works.

phector2004 · January 31, 2011, 01:06:07 AM

Yup, looks good to me too!

But don't forget the resistor, unless you want the LED to turn yellow, then dark

With 4x24V drill batteries in series, they also turn smelly!

EDIT: Oh, and I think there's a reason why people put the resistor on the positive side of the LED... In case it shorts to ground?

That's a beautiful thing, :icon_biggrin:congatulations!
I guess now you can get some sleep.

deadastronaut · January 31, 2011, 06:47:30 AM

morning..YAWN!..stretch , cup o' tea...etc........

@phil..righto!...i'll try it on 4x24volt batteries later then...with the led resistor of course.

arghhhhhhhhhhhhh surprise surprise...it blew up!..

.(only joking)....oh yeah phil, i'll try my other 555's in it and see how it gets on ok...

@ben, yeah sounds really good now. i guess you'll have to update your lovely little 1590a again....but worth it.....

well today i'm going to be looking at drawing up a pcb for it , instead of vero...get it nice and tidy with added led and resistor on board too...
if i get round to it....i may be some time...my first pcb design..i usually work in vero......probably lots of mistakes etc...but hey worth a try..

c ya later guys...i'm so glad this li'l b*****d is sorted...

Hides-His-Eyes · January 31, 2011, 07:09:25 AM

has anyone built this dead bug style?

deadastronaut · January 31, 2011, 07:18:38 AM

not that i know of...

@dragonfly, yeah i came across that, on my web wanderings, looks good, i tried it with my dodgy 2n2222a's and a j201 but it didnt work...
i havent tried it with my 2x 2n2222a's that do work as a negistor though!...may have to re board it...thanks man.

J201 wont work - you need a jfet designed for switching applications, like a j113

I know of an alternate transistor that would work every time! A uni-junction transistor would work I do believe. 2N2646 is a good example of one.

The Vox Repeat Percussion uses a unijunction (also a 2646 IIRC)
