Success!

I picked up a “farm jack” and a 3/8” chain to pull a wood post set in concrete.

This one was rotted off at ground level, so I had to dig down a bit to get the chain around the concrete.

Jacking this succeeded in breaking off a big chunk (progress!), but leaving the post and most of the concrete in the ground still.

I used a hammer and chisel to break additional concrete, exposing enough post to wrap the chain around.

This had enough grip to pull the remainder out.

New post is set with concrete, I’ll reattach the fence tomorrow.

Project #minirack is done :)
The goal was to have a nice "living room capable" 10" rack to hold my #homeasssitant box with a touch display for smart home control, a network switch and a UPS.
And no it is not living in the livingroom now, nor was it planned ;) I could have moved the network wiring to the back/inside, but in the end it needed a little nerd factor.

Mostly made from laser cut plywood in #kumiko pattern that I spray painted black, and some 3D printed parts. All self designed/built except for the metal rails in the corners.
And did I mention it's ALL powered by USB-C PD internally? 😍

Next project I've been doing quietly in the background... Custom designing Gridfinity storage and such for the PaintPal system.

Still a lot of organizing to go, but finally have enough shelving to hold things in a handy place. Where the minis temporarily are is to hold paints I am using while painting instead of all over the desk.

I may print the back extensions so I can go 4x5 deep for paint brushes organizers and such.

And finally, here are the 2 devices in situation: the 2-way switcher on my vintage stack (on the right of the OR15), and the 6-way one on my modern stack (between the Soldano and the red A-wai amp) 🙂

All amplifiers are now permanently wired and ready to rock, I just have to plug my guitar, power the amp(s) on and use the switcher to select the one I'll be playing 🎸🤘

Amp switcher: the build 🧵

I went with Hammond 1441 series enclosures, as they're made out of steel and can therefore bear the weight of a few tube amplifiers stacked on top.

This made drilling difficult (especially the holes alignment), so I'd recommend going with aluminum cases if possible.
