What have you been working on in 2020?

Building small electronics lab.  So far I have:

Soldering Station
Microscope
Oscilloscope
Arbitrary Function Generator
Bench and portable multimeters
Logic Analyzer
Power supply
Antistatic work mat

I started to play a little bit with the smallest of Arduino micros: Seeeduino XIAO
This tiny 3/4"x5/8"  $7 module can be soldered directly to PCB and reprogrammed by USB-C connector.  Small micros are always present in modern gear to control display, keyboard etc.  My first exercise is to build tiny voltage standard that is extremely accurate and temperature compensated.  I had such large standard at work, but it was "old fashion" with big box and large rotary switches.  I plan to use tiny rotary encoder and tiny display (0.91").  I'm also learning to write programs.  Ideas for the larger projects will come later, I'm sure.

Sold my nice Hanns T-60 tt with vpi 3D arm and cartridge. Sold all of my vinyl albums.
Sold my newer McIntosh C47 preamp because I stopped using vinyl.
Now I’m going directly from my PS Audio DS sr dac to my PS Audio BHK amp. Simpler system with better SQ

I thought I might start with upgrading the stock cord on my Luxman 507uX MkII integrated amp first. I read somewhere here you upgraded the power cord on your Luxmann integrated. Did you notice any improvements in sound after you did so?

Oh, some one brought up a DIY project, so very very glad you asked...

I made a DIY cable from DH Labs shielded power and I thought I heard something akin to break in.  Goosebumps, but now that I'm used to it, I'd have to remove it and go back to the original to really say.  I do think going shielded is the way to go, and it looks big and powerful and stuff, so I'm happy I did it.


Best,

Erik

This is the real stuff right here:

Way to go @au_lait ! :  Also, don't forget the girls.  They need to solder too.
