(noob question)

1. Can I change the 3pdt (record/stop) to a momentary switch so I can record only while the button is pressed?

2. If so, can I have the loop played immediately after the release of the button?
   (instead of pressing another button)

thanks.

I had the same ticking noise, with "rate" knob controlling the speed of ticking.
I've found out that when I move one of the pots (dont remember which) away from the input jack
The ticking stops.

Good luck.

hey guys,
Did you ever get something working when you know it realy shouldn't be?

I've modded my pork barrel so I would be able to choose between R39 (4.7k) and 22k (depth mod described in the pdf) using spdt.
Then, while trying to fix my ticking problem, I've removed the 22k resistor+wire and I was left with what you see in the lower image. The big surprise here is that the mod still works! I use the switch and have a greater depth added.
Can someone explain to me why/how does it work?

Thanks, I'm going to try it (the resistor switching mod) and report back 

Hey guys,
I was just about to solder the parts when I've noticed that there's an option in the instructions to change
the resistor R39 for an lfo indicator/depth mod.
Would you recommend this mod?
Thought about using a spdt switch to change between the two options. What do you think?

Thanks.

I totally agree, but it feels awesome once you get it to work.
And that loophole thing is great btw.

A simple word of advice for all of you guys - use extra wire in your circuits!
you'll need it when the time for enclosure comes.

-------never mind, it was just a bad solder joint on 1 of the pots, thanks anyway. ------

Hey guys,
Need your help with the loophole project.
Built it, tested it once, it worked. the red light appeared when I recorded and the green light when I played it.
Now I've put it into an enclosure and it's not working right. I'll describe: when I press the record button both lights (red/green) are on (is that OK?), and when I try to play the loop nothing happens. Checked the connections - seems ok.

Someone got an idea?
Thanks.

*BTW I used a isd2560 chip and soldered legs 7 and 8 to 6 (ground) - like some1 suggested in another thread.

Sgmezei, U're the man!
Thank u so much.
Will post some pics/video once it's done.

Hey guys,
Before I start I have to say that my knowledge about this stuff is not that good (yet ) .
I'm working at the moment on the LOOPHOLE project, and wanted to be sure of some stuff
before I solder the components:

1. Capacitors: I know that one should usually choose a voltage rating of 16v-35v. I've used voltage 
    ratings between 16v-100v. I assume that it's not a problem, right?
2. Capacitors 2: I've used some ceramic caps instead of polyester film caps (according to the PDF's picture)
    I know that in general ceramic is the least favorable type, But should it work?
3. Regulator: I've got a 7805 but it seems a little big. I can also see from the picture in the PDF that
    maybe a 78l05 is being used. Which one to choose?
4. The layout diagram shows that there are two jumpers underneath the IC's. I just solder them as the   
    diagram shows? maybe it's better to put them on the opposite side of the PCB?

Thanks U for your kind help.

Thought I'd use this post for a noob question about Loophole.
Just bought the parts from Tayda and I'm only worried about the caps.

I had to order caps in the following values: 100n, 1uF, 22n, 220n, 10uF, 100uF.

I didn't know which type of capacitor to order, but tried to keep the voltage rating below 50v. (depending on the supply from tayda). so I've ordered:

100uF 25V 105C Radial Electrolytic Capacitor 6x11mm
100uF 35V 105C Radial Electrolytic Capacitor 6x11mm
0.1uF 50V Ceramic Disc Capacitor
1uF 50V Multilayer Ceramic Capacitor
0.022uF 50V Ceramic Disc Capacitor
22nF 0.022uF 100V 5% Polyester Film Box Type Capacitor
220nF 0.22uF 100V 5% Polyester Film Box Type Capacitor
100nF 0.1uF 100V 5% Polyester Film Box Type Capacitor
10uF 35V 105C Radial Electrolytic Capacitor 5x11mm
10uF 16V Radial Tantalum Capacitor

Do you guys notice a mistake in my order?
Thanks.

Thanks for the fast reply.
I guess now it's time to do some research on ISD25xx,
and find the IC with the best recording time/quality ratio.

JakeFuzz, two questions:
is there any chance u've got a pictue of the modded pcb?
does it matter which 25xx I use? (recording time differences?)
Thanks.
