first pedal.

pazuzu · October 15, 2009, 01:31:30 PM

so i am going to try to make one. what's the best choice for an easy build? prefferably something i can build with components available from radioshack.

Beginner project: Gus NPN Booster! One of my fav boost actually. A pictorial walkthrough by Aron...

Edit: Aron even sell a kit for supporting DIYstompboxes forum: http://diystompboxes.com/zencart/index.php?main_page=product_info&cPath=6&products_id=47

RAtShack can beat that price...

pazuzu · October 15, 2009, 01:47:03 PM

cool. thanks for the link.

and teh noob question:

what does the q stand for in the layout please?

The French connection · October 15, 2009, 01:53:40 PM

q=transistors in layout

If you have any question don't be shy to ask everyone around will be happy to help you.

Good build!

ok cool man. i have an old swr footswitch enclosure i was hoping to use. measures 8x6.75 cm inner dimensions, would the board fit? also could you give me a link for buying the boards?

everything else seems quite simple.

The French connection · October 15, 2009, 02:11:51 PM

What kind of board stripboard or Perfboard? You can find Perf at RadShack i bet but check the store link above for stripboard, they are cheap and fast shipped! Don't worry, i got no commision for promoting the DIY store.

ahhh i see, the board is just a non conductive medium to mount everything to. i can just make that myself so it fits into the case.

i have been wiring guitars for years but i have never tried to make electronics, i thought the board routed the current somehow.

The board for your boost will be quite small so i doubt you will have troublefitting it in your housing. Perfboard (found at RadioShack) is what you describe above, just holes laid out for easy mounting and you route it yourself. Stripboard (also called Vero) has conductive strips making routing simpler for many applications. As mentioned above you can get it at the forum store. Mouser also has expensive but very nice stripboard. I built my first boost (a SHO) was built on perf, but I prefer to use stripboard now.

Good luck with your project. It's addicting, I'm sure we'll more from you!!

cool. you guys are friendlier than the average forum people.

by the way i am noticing a lack of an on/off switch, how is the battery draw regulated?

That's because there's no average people around here!

Check the switching: http://www.diystompboxes.com/smfforum/index.php?topic=970.0

If you don't use a LED indicator , you can use a DPDT instead.

Cheers!

Why you solder eatin, pedal breakin... .. .. I bet you want to know what the friggen circuit sounds like too!

ok i get it so these board layouts are independent of the switching. screw leds, maybe i can find a 5k pot with a push pull dpdt. i was thinking of trying to make one of these fit inside a guitar.

that's more like it.

Nah, as being somewhat new here to this forum myself, everybody has been suprisingly helpful and nice.
And what's more, if someone is too busy to help you, they'll let you know.

I asked this fella if he could help me with a schematic and rather than just ignoring my personal message, he said he was really tied up and probably couldn't help me but pointed me in a direction rather than just leaving me high and dry. I appreciated that..

If you dig the whole pedal thing like most of us do you'll find this place being pretty useful. And what's more, is if you know where to look you can often times find just about anything you need.

/wave.

pazuzu · October 15, 2009, 06:49:17 PM

well, i started wiring guitars a long time ago, and this seems like the next logical step since i have a lot of time on my hands.

liveloveshare · October 15, 2009, 08:51:30 PM

let us know how it turns out. :]
got any ideas on a theme?

pazuzu · October 16, 2009, 10:19:42 AM

well, here's the enclosure.

it has a small hole in the front where the cable came out, i think i am going to put a dpdt mini toggle there, and mount the pot in the existing switch location (this will be an "on top of the amp box") and drill the in/out's on either side. i would imagine as i get better at this the enclosure will be upgraded to house more ambitious projects so i am going to wait to punch more than in/outs.

by the way, i still have the interstellar overdrive unit, and i am thinking of selling it if anyone is interested.

petemoore · October 16, 2009, 10:40:16 AM

Nice box.
As long as the connections are made no board or anyboard will do.
Perfboard is preferred, most the pedals on my board have perfed-circuits.
I like to buy the big-chunk-o perf, then score along a row of holes and break some off, build the circuit from left to right on the rectangle of perf.
Runoff Groove has perfboard templates, also there are many layouts of perfboard circuits around, advisable to start with verified layout.
Count the nodes and # of connections at each node, polarity of any components that'll be connected there, plan the component lead arrangements for easiest soldering.
Consider the top of the board as useable, a bit of component lead here makes it easy to locate test-points, Gnd., V+ etc., or say re-doing the power supply wires, very easy to locate and solder ''from above''.

pazuzu · October 16, 2009, 11:09:55 AM

yea i am going to order perfboard. just seems easier.

if anyone has a minute could you verify my radioshack order to confirm i have ordered all the proper res/caps/tran? thanks in advance. i have the 1/4" ins on hand.

once i am sure it is correct i am going to order it up for 19.98$ unless you guys have suggestions.

The French connection · October 16, 2009, 11:43:14 AM

This layout is for stripboard. Not perfboard! C1 is not 1µF but 0.1 µF so it has to be polyfilm or multilayer ceramic.

Dan

pazuzu · October 16, 2009, 11:49:08 AM

thanks, i understand the layout was for stripboard but as long as i build the circuit it doesn't matter right?

as in the difference between the 2 is that stripboard is conductive on the horizontal axis. yes?
