Let's see your finished DIY projects!

I usually avoid posting in this thread because most of my builds are business related, this one, however...

Rad! Great to read about the process. Loving playing with it.

Here's my utility build of the day :



Ground isolator with various noise clean up options. And XLR speaker switcher.

Old school transformers because they are about half the price of new ones at only 4x the size.

really interesting reading about the process, makes me appreciate it even more now. it was stuffed full!

Really want to know how this works (switches, etc.) and how you use it in your studio. Was it pretty expensive to build? And did it solve the problems you were having that inspired you to make it?

[crochambeau]

Are those octal based transformers? Surplus, or does new production still exist in that form?

[imJonWain]

It looks like it. They still make octal based transformers and relays as far as I know, just not super common. The equipment at my work used for dicing wafers uses octal sockets, stuff is from the early 2000s though.

[DRodriguez]

Yup, octal base. These are old reused transformers. Altec Lansing 15335a. Similar specs to modern Jensen transformers you find in all the high end gear at a fraction of the cost. Not sure bout modern production of similar devices, but old ones in good condition aren't overly hard to find

Middle switch is a speaker switcher. A-Off-B. The switches to the left and right are a mirror of each other for the left channel and right channel. So you have 2 pairs of 4 controls. They basically break ground at different points or throw a capacitor in for filtering at different spots. Total cost to build was around $120 Which is fairly cheap for the quality. Jensen sells a comparable circuit for around $270. Definitely solved my issues.

Umm...this page...fuarkkkk

Not posted here much of late, but getting back into building effects stuff and finally built something not currently in production I got this working today-





Schumann PLL built the hard way. Totally bonkerdoodles.

Yeah Alex's layout is what I used too I built both mod boards into mine as well, there's a pic of it a page back or 2. It's a fairly complex build.

God damn your build is beautiful! I don't know how I didn't see that. Do you have a photo of the guts?

Thanks man, I didn't mean to sound douchey with my self rep there Haha! I like your build too, I respect anyone who gives it a go. At least you don't have to match finicky germanium transistors or something with it. It's just a nightmare of wiring.

I sure do have pics of the guts.. and yeah they are horrible. Yours is much neater than mine. I will say having seen gut shots of a couple of the original Schumann units .. mine is at least cleaner than his were your wiring is very nice.

[$harkToootth]

I really like the aesthetics of both your builds.

Thanks man, it was a labor of love .. and I love hot pink

[Achtane]

Hey, I finally made a thing.

I've built a few kit pedals before with mixed results, but this is the first circuit I breadboarded from the schematic, modified a bit, drew a perfboard diagram for and assembled. It even (mostly) worked from the first try, simply amazing
Definitely a confidence booster.
It's just a Bazz Fuss at heart, but I'm very happy that it A) works, and b) sounds neat.
So it's actually two circuits on one board, because the right footswitch sends the output from circuit B into circuit A (making a Buzz Box).
The toggle on the right switches between silicon diode and LED. The left two toggles switch between a single transistor or a cascaded two-transistor Darlington pair for each circuit. I'm sure there is some fancy switching method I could have used in order to apply that to both circuits, but I couldn't brainstorm it. It's a 6-transistor BF

Sounds pretty badass for something so simple. I could ditch the volume knob altogether, or really add a booster to the single-circuit mode. It's about unity gain right now. Maybe next time.
I bent some scrap steel for the enclosure, and stained some plywood. Didn't have the patience to wait for the spray finish to dry, so instead I wrapped it in gauze, dumped alcohol on it and hit it with a blowtorch.
Protip: don't use this finishing technique as close to your garage door as I did.
