How Do I? Beginner's Paradise. / Re: Eagle help

Hey man. Yeah been away for a while trying to do other things as well as building pedals  ;D

Thanks for the info, much appreciated. I will have a look at that sub forum now as I have another Eagle question.

I didn't realsie you could make shortcuts. Having to keep clicking copy/paste/delete etc is a real pain! Haha

Thanks everyone for their help. I'll check out Kicad as soon as I get chance.

Ahh ok, thank you. I wasn't aware there were issues with Eagle. I'll check out Licad for sure. Hopefully I can import the schematic I spent a few hours drawing up in Eagle today  ::)

Thanks again

Me again.

Can anyone point me in the right direction of the most up to date MBP Eagle library? The one I have doesn't saeem to have working 9vt ir GND pads.

Also, the gaussmarkov library doesn't seem to be compatible with Eagle 9.5.2 Free (mpost recent version).  >:(

Thanks again

Hi all

I've recently decided I'd like to get my head around Eagle. I've drawn a schematic up and have converted it to a board layout but I'm overwhelmed by the options Eagle gives you for things like trace widths, board layers, polygons, etc etc. I was just wondering if anyone knows of any good videos or online tutoruals that run through the basics of eagle for pedal makers?

I've had a good Google for help but I'm just getting lost in the sea of info out there.

Thanks as always!

How Do I? Beginner's Paradise. / Loop strip wiring question
« on: March 08, 2019, 05:11:17 AM »
Hi all

I am looking to build a bypass loop strip with a Klon buffer at the start of the chain using the below wiring diagram:

My favorite fuzz doesn't like having a buffer in front of it and so I would like to modify the wiring to include a switch that is not connected to the buffer and so sits independent of the rest of the chain. Would anyone be able to help me out in how I might go about wiring this up? For convenience please feel free to add to the below image:

As always, thanks in advance for your help

I've just tested it and what Madbean/Brian said above is (of course) correct. The resistor can attach to any leg of the LED.

Every day is a school day.

Cheers Brian!

Thank you, greatly appreciated.

Just to be clear: The resistor can go on either leg of the LED?

I've always assumed that it needs to go inbetween the 9v supply and the positive leg to limit the current before it hits the LED.

Hi there

I am planning on building an 8 way TBP loop strip for my baord. I have done some Googling to look for a good wiring diagram but everyone I have found either does mopre than I need (tuner out etc) or is unclear in someway (at least to me). The one I found that seems to best fit the bill for my needs is this one:

The thing I am questioning is the LED wiring. It seems to show the LED taking 9vt from the DC jack with a pull down resistor attached between the negative leg of the LED and the 3pdt. That doesn't sound right to me. Surely the resistor should go between the DC jack and the positive leg of the LED?

Secondly is there a limit to how many LEDs can be powered off 9v? Will each one need to be connected directly to the DC jack in parrallel or can I string them together in series?

Thanks in advance

How Do I? Beginner's Paradise. / Re: Extra + and - pads on SAWSE board
« on: August 10, 2017, 05:00:20 AM »
If I look in the build doc, there is no +9V connection at the lower end of the PCB: it's ground, LED switch ground, LED+, LED-, in and out. Makes sense as the switch does not need 9V  8). The bottom ground pad is connected to the top ground pad (you can check with a DMM set for continuity). So, the top 9V+ goes to your testing rig, either of the grounds, and the in/out.

Ahh ok, thank you. I was even more confused than what I thought!

Thanks for setting me straight!

How Do I? Beginner's Paradise. / Extra + and - pads on SAWSE board
« on: August 10, 2017, 04:37:38 AM »
Hi all

It's been a long tome since I put a Madbean board together and have seeminly forgotten some of the basics.

The SAWSE board has the usual four 3pdt connection pads at the base of the circuit: In, Out, 9vt and Grnd

At the top of the board are extra pads for 9vt and Grnd.

My question is do I need to connect these two extra pads to my test rig when testing the board or do I just need to connect the four 'normal' pads?

Thanks in advance

That would be enormously appreciated!

I've heard this about the Expandora before but when I've looked at YouTube videos no one seems to mention the envelope 'feature'. Does it definitely drive more the harder you play?

If you listen, the harder he plays, the splattier and nastier it gets. I still think it'd be a cool effect with a nasty enough fuzz that responds well to saggage. One day...

Anything we can do to encourage you?

I've always fancied an OD that drives the harder you dig in, should be the same kind of idea I guess?

Thanks guys!

I'll check them out.
