Title: MadBean Wavelord (extra-wide)
Post by: dawson on March 26, 2022, 12:57:37 AM
I'm super excited to finally present my newly completed MadBean Wavelord tremolo:

I say "finally" because I really wanted to finish this build to enter into last year's BOTY contest..months ago..but I'm glad I didn't rush it.
This is one of my favorite DIY circuits and this build deserves all the extra attention I gave it because I know it's going to be in my board indefinitely.

The graphic is a layout of the different wave-forms that I basically traced from the build doc's then embellished to fit my design.  It's etched into a 1590BB bottom-plate with ferric chloride.
Did I add the external LFO jack?  Of course I did.  This is my second Wavelord, so I know it plays great with at-least the Parasit Studio 0415 Guitar Synthesizer *I haven't tried anything else.

Where I strayed from stock:
- I did some extra off-board wiring to enlarge the format from 125B to 1590BB.  I like my pedals to sit right next to each-other, so with that as a rule, the only way to get extra toe room is to enlarge the enclosure.
- I used a version 3 VFE switching board to add optional momentary switching.  It's mounted underneath the main PCB with a 3d-printed bracket, which was a tight fit, but the version 3 boards are great to work with.
- Just for fun I added a toggle switch to change the way the LED's work: In the 1st position, a large Red LED acts as a status indicator, while 2 small Teal LED's flash the rate underneath it, always on.
  This is neat, but if I get tired of constant blinking, I can toggle to the 2nd position, where all 3 LED's work as non-blinking status indicators.

^I guess I didn't get a good picture of the final bracket before I put everything together, but here are a couple pictures of a prototype.
The final build had an extra couple fingers on it to hold this strip-board that trims my excessive LED arrangement, pictured here:

If you're wondering WTF is wrong with this guy who thinks it's okay to build upside-down pedals with no pants on, this thread may answer a question or two:

I'll add some photos with the Wavelord in rack-context very soon- I finished it this afternoon and have only had time to test it outside of a box so far.

Oh man.  Superb little daughterboard holder to boot.  I really gotta get into 3D printing...

Yeah!
"the sooner you start" etc..

You do NOT need an expensive machine to make functional parts.  My parts don't come out the greatest- I've been using the same desktop machine since 2015.  It's a dinosaur for 3d-printers, and it bears all of the scars from the mistakes I make while learning, but they work fine for what I want.

I got a head full of ideas of stuff I'd like to 3d print one day. What software are you using to design stuff like that clip?

That looks incredible! Really dig the direction you took with the artwork here (and the 125B build). The mods turned out great! I think widening the switches is a good call—I've been considering the same on a second build since it can get a bit cramped.

I use Fusion 360- it's free!
Get a dependable pair of calipers and you'll be on your way.

After aaall the finesse Brian put into working everything into a 125B!

Nice, I also like my builds in layers.
The 3D printed part is a nice touch
Using the lid also helps to get a better view, have to try that one at least once.

^Thanks a lot for looking, everyone-
I really appreciate the kind words, they really mean a lot coming from builders who I look up to so much!

Your whole system is just super cool, and I love the graphics style you are doing on all of these. The Waveform thing is great on the artwork. I typically don't like two switches on a 125b either, but I have monstrously wide feet (or at least it has been put that way by my kids).

I totally second that, I have an Ender 3 which I've recently seen going for as little as $100 on sale. It's nothing fancy but it can do a lot and do it well.

I have been just doing everything in tinkercad online. I keep forgetting fusion 360 is free to hobbyist. Is it noticeably better than tinkercad?

Great build! And very crafty with the piggy-back holder.

Unfortunately I don't know any other modern programs to compare Fusion 360 against, so I can only give you a non-answer.
The only shape I haven't been able to figure out how to model in '360 is a curved horn, but everything else has been fairly intuitive.

So, for months I'd been plotting and planning an overcomplicated way to control the tempo of my WaveLord with my Eurorack set-up..
Until yesterday I decided to read the data sheet for the Electric Druid Tap LFO chip and realized there's an incredibly simple way to do it!

(https://media.newyorker.com/photos/5909534f6552fa0be682c5d3/master/w_2560%2Cc_limit/reading-rainbow1-thumb-300x455-15224.jpg)

The chip can be clocked with any pulse 0-5v, which matches the output of my Eurorack clock, so all I had to do was check out the schematic and tie a mono jack into the circuit to receive CV (control voltage.)

Three-cheers for reading!

The red wire is the new addition.  It connects to a jack mounted in a small utility module.

Super simple.
Eurorack and guitar effects all synced up- it's a happy day in SCHMORG land!
