What Are You Building Today

I like things straight, what can I say.
 

So looking for advice. Do I attach my steel wall to the concrete and live with a wavy line, or leave a gap and fill it in later with concrete. I plan on using metal stakes and concrete on the back side of the not-so-great-wall so that would make it straight..

I already want to raise the wall a bit so this is just a dry fit to mark the holes for the to be concreted posts

I doubt any fix would make it look much better.  I feel like I'm missing some overall perspective from the picture, like what is what, i.e. are you calling a "wall" something that's on the ground?  But fixing/blending/hiding a joint in concrete generally doesn't last.  Possible option would be some kind of coating that would span across the joint or if applicable, decorative trim to hide the gap/wave.

Not to disrupt the construction portion, but just got this up and running over the break, and put it in the system for a listen today. In my typical tradition, currently uncased. This is a UGS Muse preamplifier. This uses the UGS 3 Universal Gain Stage (Pass Labs XP 12 and I believe XP 30 use these), with the Muses 72320 volume control chips. This was developed on a French forum (homecinema-fr.com), originally with a relay-based volume control, and then updated with some redesign for the Muses chips. There are threads on diyaudio for a board group buy there as well.

The preamp is fully balanced differential, with 4 inputs and 2 outputs. Even though it provides a HT bypass function, I may hardwire one of the outputs for monitor functionality for headphone amp use. This uses Salas shunts providing the +/-24V for the UGS modules, and regulated down to +/-16V for the Muse chips. Custom Toroidy transformer (4x24V and 2x8V secondaries, dual 115V primaries in their Audio Supreme version).

This was mostly surface mount, and was a challenge to build. The 100 pin CPU (STM32 ARM) was a good time to solder, with a size of about a dime.

I've only listened to this for about 20 minutes or so today; it sounds very good, but getting the Pass Aleph P out might not be so easy :)

The last picture isn't mine, but shows another builder's case layout. Mine will be somewhat similar I think.

I see. So the steel pieces are the wall. If I secure it to the concrete on the right (yes Al is correct with his marking) then it no longer will be straight. If I don’t secure it, it will be nice and straight, but there will be a gap between the steel wall and the concrete on the right. I would need to fill it with some sort of coating (Sika makes a self leveling material and there is some you heat up as well..)

What's the maximum gap between the steel and the concrete?  I really can't get a sense of scale from the picture and I think that's what's causing part of my difficulty.  

What might be possible is to set the steel straight, use it as a guide, and then cut a chamfer into the concrete to create a gap that looks uniform at the top and hides the variability that exists below it.  Not exactly sure how I'd do that without staring at it a bit longer but that was the first thought that I had.

Son of a *****, I've been looking for my testicle weights for years! Thinking back, it was about the same time as we last got together in person.

Do you understand the implications of being a gay top with tucked up balls?

Built a vent board for our van AC unit that fits in the back window since they do not provide one and the only prebuilt one was really pretty cheap. This one is much more solid.
