Im having a go, help me along!
« on: March 27, 2007, 02:33:30 AM »
Heres a copy of my shopping list for the pedal before I order it. Does it look about right?

PerfBoards
VE9542: VERO-TYPE BOARD 95 X 152 -
VE9552: EXP PC BOARD 29X50 HOLES (1450)
   

CF.1E: 0.1UF 100V P.FILM 5MM 10% - Metalised Polyester Cap

RA100KX: 100K 5% 0.5W MF RESISTOR (SFR16T) ROHS - 0.5W 5% Metal Film Resistors
RA10KX: 10K 5% 0.5W MF RESISTORS (SFR16T) ROHS  - 0.5W 5% Metal Film Resistors
RA47K: 47K 5% 0.5W MF RES  - 0.5W 5% Metal Film Resistors

2N5088: N NF ra 35V .05A B>300 TO92 - I searched for the transistors recommended and these came up
2N2222AX: N UNI 60V 800MA 250MHZ TO18 XPB - I searched for the transistors recommended and these came up

PBR305: 5K LINEAR POT SPLINE SHAFT 16mm - Pot (does this look right?)

CNICM24 - 24 PIN IC SOCKET M/P - 24pin IC Socket to pull apart and make small sockets from.

BH602 - 9V BATTERY SNAP QUALITY TYPE - Battery snap

CNPA5D - 6.3MM STEREO PHONO OPEN JACK CHAS - 6.3mm Stereo Jack
CNPA5D - 6.3MM MONO PHONO OPEN JACK CHAS - 6.3mm Mono Jack

CAF0.5BLK - 0.5MM HIFLEX CABLE BLACK - Hookup Wire

I already have a DPDT switch from out of my wah, so don't need one of those.

I'm not going to buy a casing yet because they are expensive and i'm not sure what size I'll need.

I'm also ordering in a bunch of bits and pieces for later use.

But does the order look complete and are the parts okay?

Thanks for the help, I'll keep you posted with how im going once I order the parts, I'll do pictures if you want too.
i have to get my hands on some of your germs.  very soon.

I always forget something from my order, its a nightmare. Especially when I order from the US and I live in the UK. As soon as I press the confirm button you remember you need some knobs or a dc socket. So annoying. Last month I ordered parts for a GGG mixer pressed the confirm button and realised I forgot to put knobs on the order so I emailed smallbear and asked them to put some on for me, which he did. When the order arrived I'd forgot to order bloody pots as well. A mixer without pots, have you ever heard anything so stupid! Oh well, it gives me an excuse to build another pedal so I can get the pots to finish the mixer! Yeah!

Lol... Thanks for reminding me I need knobs! That would have been annoying haha you just saved me.

I think I have a DC input somewhere but I doubt I'll need one.

It's good, this shop is in my city and do deliveries - they arent open during the week so I could never get a chance to go in.

Also, if I am successful making this pedal, and I want to turn it to a Fuzz - how hard is it to add a tone control circuit? Any links?

Please could anyone look over my first post and tell me if those parts all look okay to use? I really want to get started but don't want to order heaps of useless bits. I want to order the parts ASAP, just have to send an email.

Cheers

Fantastic, thanks RaceDriver!

I will order the parts today, I cant wait to get playing around with this  :icon_biggrin:

This thread discusses tone controls pretty well I think, and you can use the type of tone control Yun describes in almost any circuit.

Oh awesome thanks!

My order arrived today, now I have to sort out all the components!  ???

Should be fun anyway. The brushed aluminum knobs I got will look pretty sweet

How would I go about adding the Diode Compression Op-Amp to this circuit if I choose to turn it to a driver?

Okay I'm going to have a go at this tonight most probably, after having a look a my Rat and my wah.

One of the boards I got is the type with long rows of copper, is this usable or does it just make things a lot harder?

I prefer the board with long strips of copper (veroboard or stripboard)

It normally means the layout has to be different... google veroboard and look at the differences you will need to make to your layout... I'd explain it to you, but its really hard to do without drawing loads of pictures, and I dont have time... I am guessing you've used perfboard up til now...

Well actually I havent used anything up till now haha. I have veroboard and the normal board without strips. So I guess I  can use either.

Well, you already got your order ;), and now it's time to build.

One remark only, I believe there's no need for 100volt caps. With 16v is enough. or 25 for the mosto common values. It won't make any difference, just size. And the day you start to create your own PCB which are tight, all your caps won't fit :o ::)

Just for the next one ;)


See you

Oh cool thanks for the voltage info, I wasnt sure so I just went for the 100V.

Also my resistors are tiny, they are 1/2W, is it 1/4W which are the usual? I dont think the shop stocks them

1/2 watt is bigger than 1/4 watt resistors. You should be fine with the components you chose.

Okay I have built the board but it does nothing, I don't have a switch so it is just on at all times.

is there a way of hooking up a 2pdt switch from a wah? This one has 2 lugs one side then only one ont he other side...

I have tried my transistor both ways.

I get sound through it, but turning the pot does nothing, so at least I know it isnt totally bung.

Any ideas what to check on it?

I just pushed on the lugs on the pot and it works!!! Perhaps just a shotty job of soldering the cap.

Awesome!!  ;D I deont have a mic at the moment, but sound clips will arrive.

Now, next project in site - how do I add that Op Amp circuit to this to make a fuzz?

Im just trying to wire up a Boss switch to it, i have it working good except it doesnt stay on when pressed, it just stays on when you hold it down, how do i do this?

Well a Boss switch is a momentary switch (i.e. its only on when you hold it down). In boss pedals, the circuit includes a sub-circuit called a flip-flop, which toggles the effect on or off. You should look up CMOS switching circuits on geofex.com

Or just spend a fiver and buy a proper switch?
