Tech Help - Projects Page / Zpsdx v2
« on: August 05, 2018, 08:28:16 AM »
Hey Guys,

Been a bit since my last post.... but reaching out for some assistance. I've had the zpsdx 2 board in my drawer for a while, and recently made myself order the needed pots. After building up, all voltages on all IC's are ok except on the pt's. I am getting 5v at the out of the regulator, however at c58 I am not reading 5v, usually only half a volt.  I've checked all the components on that trace and can't find anything obvious, and gone over the entire board a few times to check for cold joints, orientation etc. my issue appears to be  in this general area, but I am stuck. for testing, I have s1 and 2 jumpered. Any thoughts? (edit: picture to come, I have to scale down the photo quality)

It's been a while since I've checked in, and I felt the forum tug (huh?), so I figured I'd check in. As soon as I finished my Mfos soundlab mkII synth project (around a year ago?), I more or less became addicted to synth and have since been GAS'ing super hard with eurorack gear. There's plenty of DIY projects out there from companies like Bastl, hexinverter, musicthing and 4ms, so I've been busy. Pedalwise it's just been a few here and there. I've even learned how to compile firmware and flash to mutable modules (stm32 based) in preparation for an elements build (super pumped).Anyways, here's a shot of the setup, which for some reason continues getting bigger everytime I take a photo. The wood case on the top right of the eurorack stuff was on old CD rack I found at the thrift store, stripped and refinished and installed rails into. I recently finished it so I'm kinda proud (:

Tech Help - Projects Page / Building a multi box for a keyboard
« on: May 22, 2015, 02:56:41 PM »
Since my last 2 amp projecs have ended, I've fallen into a "big project" depression, and was desperately trying to come up with my next non pedal idea. While at the thrift store I found an old tower speaker with a good quality plywood case. I have an old Casio keyboard that I often run through my effects chain and absolutely love the sounds I can create. So I've decided to take the old speaker enclosure and make kind of a multi/modular panel looking thing for it. I've got room for 8-10 effects and I want to utilize all of it. I also just ordered a clear blue cut of acrylic for the front panel and want to make it shine with super brights when turned on. When it comes to powering this thing, will a one spot be enough currentif I am daisy chaining all of the effects inside the box? My current guitar setup which includes probably 10 effects (3 delays and 2 reverbs) does fine with the one spot, and ultimately this is just a big old multi in a weird enclosure, but I was wondering if anyone had any other suggestions/tips. The unit will likely consist of a delay, 2 different trems, 3  filter effects, one of Fredericks awesome noise makers, beans auto wah, and a few I havent decided on. Thanks dudes!

Open Discussion / Item from ebay help...FX90
« on: May 21, 2015, 04:15:37 PM »
Hey guys,

I recently won an auction for a  dod Fx90 analog delay on ebay for about 100 with shipping. The seller had advertised it as new, and included the box and all the original materials (even the freaking DOD sticker that came with the pedal, the schem, and owners manual!) Cosmetically, this thing is nearly perfect, and I love that it came with everything. The problem is, it is not functioning properly. The pedal will randomly start oscillating (irrespective of the repeats knob position). It also goes into oscillation a lot earlier than what I've seen in videos. The seller does not accept returns, however I think I may be covered since he advertised it as new and it certainly isn't working properly. The question is this-I'd hate to let such a pristine example go back due a minor concern that may be easily fixed. I've sent him a message to at least let him know what is going on and am waiting for a reply. Should I troubleshoot and work this out, or go through the process to get my money back and try and find a properly working one, which will likely not even come close to how pretty this one is?. Any suggestions would be appreciated. I've never had to deal with a seller on ebay/faulty item in this capacity before.

Is what I picked this up for. Definitely needs some love, reverb and vibe Dont work (yet), but she powers on and sounds decent enough for me to be excited at what I got this for. The guy I picked it up from thinks it's a 73 or 4- I haven't checked the transformer date yet. I think with some extra love this could end up being somethibg great. New project ftw!

Open Discussion / Attention Netflix users: LFO THE MOVIE

There's a movie on netflix called Lfo: the movie. and if the description is any indicator, it's going to rule. I'll report back once I watch it.

Open Discussion / Just found this by the curb....
« on: January 06, 2015, 08:45:24 PM »
And I don't know what to do with it yet! The image is from google- Mine isn't clean yet so I wanted you guys to see what it will look like shortly. It powers on but I am only getting white noise. Since my knowledge of tube based circuits is approximately zero, I'm thinking getting it working may not be worth the effort. HOWEVER. This would look killer as an amp enclosure ( i really want to build an amp). Anyone have any thoughts?

An old friend of mine wants me to build him a vocal effects unit and aside from delay and reverb he wants something akin to a megaphone sounding effect. It seems like that "megaphone" sound is a combination of a lot of treble, compression, and distortion, but i'm not yet sure how to tackle it. Any circuit suggestions or ideas?

Open Discussion / E Cig Mods question
« on: December 22, 2014, 04:58:30 PM »
Hey Guys,

I remember a bit back a thread on vaping so I know a few guys around here do it. For about 2 years I've been using the boring old pen style 510. It's actually got great vapor production and I don't have any complaints about it. My DIY spirit has me wanting to build my own, and I was wondering if anyone could point me in the right direction. Basically, I need to know what to buy in regards to building an atomizer, batteries, ETC. Good throat hit is a must. It's the reason I've kept my 510 for so long. If anyone has any recommendations for a good place to start, please let me know. I'm looking for a setup to drip, no tank needed.

Open Discussion / Amazing guitar work
« on: December 20, 2014, 11:58:07 AM »
Hey guys this is a link to my friend John's band called Alcon. I used to play drums in a band with him when I lived in Columbus and I've always kept track of what he's doing musically. I've always been impressed by his guitar playing but the song called exus in this link takes it to a whole new level. He handles vocals as well. For fans of owls, Jeff Buckley, and other.

Build Reports / YARUBADUB
« on: December 14, 2014, 11:17:22 PM »
This was my weekend project-population, Tex and case art friday, boxing sunday. My girlfriend started a new job a few months ago and kept telling me I needed to meet one of her coworkers because "he plays guitar too". I met the fellow and he's a super nice guy, and we got to talking. He knew I built pedals from some prior conversations with my girlfriend. He mentioned he had had no luck with any of the builds he tried. He seemed pretty bummed....I asked him about them-both were BYOC kits that just didn't work out. I offered to take a look at them for him, not expecting him to take me up on it. A few days later, my girlfriend comes home with a tupperware bin full of parts! He had tried doing their reverb and tubescreamer/boost. Both pcb's were completely shot with missing pads. Since the reverb pcb couldn't be salvaged (except for the brick), I decided to pif the world and build him a new one from scratch. I went with the rub a dub (because hell yea!). This is the result.

Open Discussion / any susskind fans out there?
« on: December 07, 2014, 01:20:04 AM »
I don't know how many forum members are into physics/astronomy, but I've been on a susskind trip lately and have found some awesome lectures on youtube. I got bit by the bug when I was a kid when my dad bought us a telescope, almost pursued physics/mathematics in college and instead went with psychology (I know) and now work in insurance.  Anyways, The channel 'World Science Festival"   has some pretty decent panel discussions on a variety of related topics. If anyone has some related sources/material to share, please do.  That is all (:

Tech Help - Projects Page / Twin peaks Taplfo Question
« on: October 19, 2014, 09:50:51 AM »
Hey Guys, I've finished populating Drolos twin peaks trem and am having a slight issue. My tap tempo isn't working correctly, and my shape knob seems to not be working properly either. Depth, rate, multiplier, symmetry, and tone all work properly. The only substitute I've made is a tL072 for the 5532. Before I dive too deep: I purchased my tap chip from small bear. Is any further programming required or should this work in the circuit as received? Thanks!

Tech Help - Projects Page / Aquaboy clock frequency
« on: October 14, 2014, 08:31:27 PM »
Hey guys, finished my aquaboy (2x 3008) and The pedal is working and delaying :) I am just trying to fine tune the clock/delay time. I've removed the whine from the signal when not playing, but I do notice a slight hint of it on my repeats. I noticed that the lowest I am able get the clock freq to is around 8hz. Any thoughts on where to start? I measured my delay pot at 1.002m.
