What have you been working on in 2020?

Spent most of the last 6 months working in the hospital.  The rest of the time I have been setting up room changes/treatments. Much better with room size change and new flooring installation.  Also spent a lot of time trying to understand how to optimally set up streaming with my system but just don't get it yet.  Everything I read discusses hardware/software with a lot of numbers and letters that seem completely foreign to me.  I just don't get it yet.  Not gonna give up however. 

Bought noise-cancelling Bluetooth headphones and then travel went away after two trips.

Decided not to listen to music while on the bicycle.

Bought a bunch of guilty-pleasure CDs.

Played mostly Bluetooth speaker. Other times, a Walkman with new earphones.

Barely remembered I have "a system".

Just received a power cord. The rubber band holding the old one at appropriate length broke so I decided to buy the cord of appropriate length. I splurged ($60ish). I would not have done it had the rubber bands holding bunches of curly parsley lasted longer on the power cords.

Observed what goes through the minds of audiophiles when placed in an unexpected and unusual situation. Thanks for the song.

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.

Building the Pass Amp Camp Amp with my 10 year old boy!

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
