Tech Help - Projects Page / Poindexter transistor error on the PDF
« on: March 10, 2012, 10:05:04 PM »
It shows 4 transistors but the PCB clearly requires 5.  What transistor should be used for Q5?
Here is the poindexter PDF:
http://madbeanpedals.com/projects/Poindexter/docs/Poindexter.pdf

I found this out because I'm building the pedal right now and I only have 4 transistors lol.  Does radioshack sell 2N3904 trannies or am I looking at a week wait from smallbear?  Or better yet, am I just reading something wrong?

General Questions / Re: Slambox and Zombii Mods
« on: November 26, 2011, 04:17:22 PM »
You can socket c1 on the zombii I found that it made a difference,even 100uF is worth a pop

Oh yea? I hadn't thought of that... You mean put a socket in there and that way I can swap out different values of capacitors?

General Questions / Slambox and Zombii Mods
« on: November 26, 2011, 02:47:54 AM »
I have a couple PCBs from awhile back that I would like to use now.  I see some notes on the project PDFs that I am curious about.


MOD 1- I see the Zombii v4 notes says "From Matt Palmer: Change C1 to 22uf and C4 to 47uf for a beefier sound!"   So who is Matt Palmer and does this work? Has anyone tried it?  I love the zombii that I have but I do keep an EQ after it to add some bass to it- it would be great if these mods would make that EQ unnecessary.


MOD 2 - From the slambox v4 PDF  "If you find this effect too bright, try subbing smaller values for R1 and R2. A 2M2 is a reasonable alternative."  That sounds cool to me as I do find it a bit bright.  The problem is that I have a slambox v3 PCB which is a bit different than the v4.

The resistors from v3:
R1 1M
R2 10M
R3 10M
R4 5k1
R5 47k
R6 2k2
 
and from v4
R1  10M  
R2  10M 
R3  5k1 
R4  47k 
R5  4k7 

So if I want to try this mod with a v3 PCB which resistors should I change out to 2M2s?  I would guess R2 and R3 but this is just a guess.  I bet there are people here that actually understand this stuff that will know exactly what to do.

Any help is appreciated guys- thanks.

General Questions / Re: Switching possibilities- would this work
« on: October 28, 2011, 02:01:42 AM »


Thanks guys.

I think I will build a second pedal and make it the second option in jkokura's post:
 " Flip flop and bypass switches. Options are: no effect, effect on with only one effect available at a time but switched back and forth with one stomp switch. "

Would someone be so kind as to show me a basic way to wire that up?

If I understand it correctly there will be 2 switches?  One to turn the pedal on and one to toggle between effects?  Or would each effect still have its own switch?

General Questions / Re: Switching possibilities- would this work
« on: October 28, 2011, 12:10:01 AM »
ah interesting.
When I built the pedal I had not considered that I may desire to hit both switches at once and I put them too far apart to step on together.
I wouldn't want to have to add 2 more switches tho.
to clarify, I would like to be able to:
1 activate just the slambox
2 activate just the zombii
3 be able to run them both at once
4 be able to switch between the two with one step

General Questions / Switching possibilities- would this work
« on: October 27, 2011, 10:43:24 PM »
I have a slambox and zombii in a single enclosure.  Each effect has its own switch 3PDT switch.  The effects can be ran independently or together.

My question: Is it possible to add a third switch? One that would switch between the effects?

My goal is to have both effects engaged but not running in line- just one in the signal at a time.  I know that there are things like A/B switches but I would like to have everything compact and in this single enclosure.  I would think that just based on logic this shouldn't be too hard to achieve but I cant find any diagrams and I dont know enough about wiring to figure it out.  Please help!

BTW- here is the layout I have used- it works great

General Questions / Poindexter - Octane shielded wire question!
« on: March 19, 2011, 08:02:43 PM »
From the poindexter info:
" This is a noisy effect. Shielded wire is recommended for the effect output"

Has anyone built this before?  How noisy is noisy?

I looked for shielded wire on smallbear but I couldnt find any- Do they sell it or should I buy it from somewhere else?

When it says use shielded wire for the effect output does that mean for every wire connected to the output?

Here is a link:

Thanks!

Build Reports / Re: Zombii Slambox
« on: January 28, 2011, 03:46:26 PM »
I've never seen an enclosure crack like that!  I like that you still used it instead of throwing it in the trash too.

Yea I just got a piece of metal from lowe's for $0.30 and cut it to cover the hole I busted out.  Then I just used some JB weld to patch it up- cant really see it when the pedal is on the board unless you are looking for it.

There is a lot of similiar situations here:

Build Reports / Zombii Slambox
« on: January 27, 2011, 07:43:46 PM »
This is my first build that wasn't from a kit -it really highlighted my incompetence with this stuff. 
Sounds AMAZING tho - madbean makes some awesome PCBs. 
Thanks to everyone that answered my noob questions here and to runmikeyrun@DIYstomboxes for all the help.

Here it is next to a 808 I built from a ggg kit


guts:


here is a pic of how I cracked the enclosure by using a worn out drill bit that was better off in the trash:


I think I may build the same exact pedal again just so I can try to do a better job at it.  I certanly couldnt do much worse.

Ok I will try that- thanks.

Im sure you're right- I think I may have several problems here.  I think my grasp has exceeded my knowledge.  Plus I found out I'm not very skilled with soldering/lead dress.

I'm sure that would cause issues but I'm pretty certain the zombii and slambox are both NPN.

Sounds to me like your power is going to ground. Do your LED's light up when you engage the pedals? How have you connected the grounds and power supply to the boards and LED's?

The LEDs do not light up, no.  I have connected the the grounds and power supply exactly as the layout I posted shows.  

Also, I'm not sure by your description, but you may have hooked your power jack up backwards. So you're clear, from the image you posted above.

The sideways tab is the 'tip' of the jack, and should be connected to GROUND

The upper tab is the 'sleeve' of the jack, and should be connected to +9V. In this case, you should have both circuit boards connected here in Parallel, not in series. The LED's should be connected here too, but you may have connected them from board connections, which is totally fine and probably preferred.

The rightmost tab, below the upper tab is the 'ring' of the jack, and should be connected to nothing. This is where you would normally connect your Battery clip's red lead. Since you have no battery, this should remain unconnected.

Yes, thanks, I believe it to be connected as you say.


If that's already correct, I recommend you take a look at this: http://www.madbeanpedals.com/forum/index.php?topic=902.0

Follow the steps for trouble shooting I outline there, and use a DMM to get yourself some power readings.

jacob
Thanks for the link.  I tried getting some power readings.  I hooked the DC jack to my one spot, inserted a guitar cable into the output jack, and then grounded my DMM to the input jack.  I got no readings at all tho.  Stranger still, I noticed that as soon as I hook up the one spot to this pedal it stops all power going to the other pedals on the one spot.  I doubt the trouble is the one spot- I have never had it do this before.

Thanks again for trying to help.

Thought I would post more info:



  The situation:  The pedal bypasses the signal fine.  When I engage either side of the pedal the signal is muted and there is a clicking sound every half second or so.  Neither LED lights up.  When I use a one spot as soon as I hook the pedal up all the other pedals on the one spot turn off.

  The pedal is 2 different circuits on one enclosure.  Both PCBs are from madbean- a zombii V.4 and a slambox V.3.  It is my third pedal build, the first two worked fine.

  I used all suggested parts.  The only thing I did different to the the layout is that I left the 2 wires for the battery off as I dont like batteries.



I hooked up the one spot to the DC jack and tried measuring some voltages but nothing moved the meter at all.

Pics:  
(I need to add here that my soldering work leaves a lot to be desired)

Yes there is a chance I wired everything incorrectly lol.

When I say 9v I do mean the battery- sorry. 

I did also want to add that I tried it with my one spot and it made all the other pedals that were hooked up to it turn off.

As far as the DC jack goes, I wired it just like the diagram (minus the wire for the battery).  I could be confused about the ring, sleeve, and tip for the DC jack tho.  I used the largest chrome piece as the sleeve and then the furthest hookup from that as the tip.  And nothing hooked to the center hookup.  I realize that may not be clear- I used this picture as a guide basically:

hi

I just built a zombii and slambox in one enclosure.  Bypassed signal is fine but when I engage either side of the pedal all I get is a clicking sound (a small click about every half second).  My LEDs dont light up and neither effect works at all.  The sound mutes except for the continuous clicking.

Anyone ever heard of this? 

Here is the exact layout I used.  The only difference is that I didnt use a hookup for the 9v.  I simply left both of thoe wires out- could this be causing this?
