There are way less PCBs or kits available for Eurorack. Thus you're often down to build stuff from the raw schematics and you have to come up with our own layout for front panels. That's why I've got much experience in vero board builds. Wiring can be an issue due to the amount of jacks, but...

No reason to worry, I strongly assume that most here feel the same :D I'm up to 8 pedals and dozens of Eurorack modules over the years.

The OPA2134 has way lower total harmonic distortion than the TL072 or NE5532, but this is IMHO only justified in circuits such as phono preamps. Thus checking for fake ones would most likely require a spectrum analyzer. But just record a pure 1kHz sine wave and then check with a simple audio...

Q: What does the trimming procedure for T1 looks like? Q: What size of enclosure is that? Going through the schematics I found that the labels for RV3 (Saturation) and RV5 (Feedback) were missing. Anyway, I'm looking forward to build this one.

Poor man's solution to clear PCB holes while desoldering: toothpick.

Since the greek character for Ohm is not straight forward available on most keyboards/fonts "R" is used instead. As @drew.spriggs pointed out, it makes absolutely sure which value is meant.

Spoiler alert regarding modifying tapers of potis

You see the downside of these drawer systems once you tipped over a drawer on your desk or floor. But if you are soldering on a daily basis it is the most convenient way. My cheapo solution: most parts come in small translucent plastic bags anyhow and I store them in cardboard boxes like in a...

Looks like a 50 Ohm BNC connector (the 75 Ohm BNC types are slightly different. See BNC connector ).

Once I retire I will sit in my rocking chair and do absolutely nothing. And after three days I will slowly start rocking.:) Quote from my dad.

Median Compressor on veroboard. Trim procedure with my Brymen BM869s multimeter. The enclosure is a TEKO B4, which is somewhat larger than a 125B, but useful to accomodate larger PCBs and a multitude of potis. In the background: part of my Eurorack stuff that provides +9V, +5V on USB jacks, and...

Dusky Electronics Hypathia on veroboard. Missed one cap and two resistores while redrawing the schematics, but found my mistakes within minutes. Lost an SMD 5457 while soldering 😢 (why always the expensive parts?). BC547C as NPN and BC517 (NOS from the 80's) instead of MPSA13. Update: Found the...

On regular PCBs you just cut the leads after soldering. In case you have to desolder a component that is way easier than on a perfboard if you bent the remaining leads to make connections to other parts. With a proper solder iron excessive heat on components isn't a problem.

Using the leads is the better option, unless you plan to replace components. Have a solder sucker pump and wick ready. Additional and longer connections can be made using insulated wire.

Seems I actually have to consider such a thing.

Lacking a proper camera for filming my setup, I'm looking for a smart phone holder that doesn't obstruct the lenses. Anybody aware of a corresponding device that can be attached to a stand?

And another interesting project! Any demos yet? I'm still wondering how the Landau Density Matrix works with just two knobs. In contrast to my initial infos it is using transistors and not MOSFETs (google simply combined the results from two different pedals 😖).

These rectifier diodes could be selenium ones, which would explain "SE" instead of "SI".

Which transistors from the BC series would work as alternatives to the 2N5088, because these are much more expensive than e.g. the BC547C ?

Using a Boss RV-6 with my modular stuff to get a stereo signal was an awesome experience. Otherwise I like the Tape Delay (DIY) for what it is capable in my pedal set-up. It really depends on what kind of reverb effect you're after.
