Current wooden spoon carving, maple and 3 cherry pieces. I'm going to sand two of these ready for finishing, the other two need more carving work.
The larger pieces came out of the freezer yesterday, spent the night in water and are lovely to work with. Working on handles that feel good to hold, the big one might be a flour scoop, or a sugar scoop for baking.
I have several old metal spoons of various shapes I use for inspiration. I love spoons!

#Docker images and installation/upgrade instructions are available in the release notes. See the announcement for more:
Make my own #guitar lead sheet(s) instead of the stupid chord sheets/tabs available everywhere.
#MuseScore seems really great for this.
The only problem is that while I know about #music than a chord sheet assumes I know less than I probably need to, for instance, line the lyrics up with the beat.
But it's all a #learning process! It's OK to be terrible! Everyone starts somewhere! (he snarled through gritted teeth)

Here's a bit of a long shot: I wonder, is there anyone around who is interested in a regular #exchange to keep accountable on #creative and/or professional #projects? I used to be in such a group, exchanging our respective progress, but that dissolved over time. I still find benefit in tandem exchanges and sangha situations. But I'm sitting on some goals that I'd like to inject more #accountability into again. If anybody happens to be in a similar situation it would be great to get in touch!
Enter #Leonard #Leo.
In the early years of the Trump administration, he and the #Federalist #Society had remarkable influence within the new government. The Federalist Society had brought the legal doctrines of #originalism and #textualism — close readings of laws and the Constitution to adhere to the intent and words of the authors — into the mainstream.
Leo had taken a leave of absence from the group to advise President Trump on judicial appointments, helping shepherd the appointments of Neil #Gorsuch, Brett #Kavanaugh, and Amy Coney #Barrett to the Supreme Court and helping to fill more than 200 other positions in federal district and appellate courts.
By the time Trump left office, he had put on the bench 28% of all federal judges in America.
Leo’s “secret sauce,” he said, was to identify an “inner core” group of people within the Federalist Society’s 60,000 members.

For anyone who missed the in-progress posts, this is a rescued ATX power supply from a computer, cobbled together with a bunch of stuff from my Misc box. While all the other nerds who have done this project have tried to make theirs look professional, I tried to make this something that I could use instantly without taking my mind off whatever I was doing. To that end, it's got soldered-on alligator clips for all of the important voltages (3.3, 5, 12) and ground, that just hang off the power supply when not in use. It's also got a couple of Micro-USB cable ends, and a couple of USB-A ports for anything that requires a different cable. The neon lights are from my 2000's era computer, and provide a bit of extra light / act as a status light / act as a dummy load for the power supply. The silver top is lasercut MDF, that I nailed every dimension of on the first try :-D
I'm so thrilled that it works so well because it was such a pain to get it to this stage. I'm bad at designing and thinking ahead when doing projects, and my usual process did not work at all this time. Couple of improvements still to make – I need to replace the alligator clip leads with a thinner gauge wire that can hang more flat when not in use, and I need to figure out where to put the neon lights.

I'm building a mental health tracker based on The Invisible Man (2000). In the show, the lead character has a tattoo of an ouroboros that turns from green to red as he uses more invisibility and gets closer to madness. My version is #lasercut rather than tattooed, and is going to work off data gathered by the home automation.
Tonight's goal is to wire up the #neopixel string and get #WLED working on the #ESP8266. If there's time, I also want to cut a diffusion layer so that I can do the assembly tomorrow morning.
