I'm retired, so 2020 has only caused a minor change in my "free" time.
The allocation has changed quite a bit, however.

But recently I've been working on:

Fixing a Kenwood KT-56 tuner (bad cap)

Fixing a "dead" HP laptop (replace the mosfet with a piece of wire.  This
is *always* the fix for dead laptops, it seems.)

Replacing the cells in a Lenovo laptop battery pack.  Got the Lenovo as a
trade for fixing the HP.

Scanning the service manual for the KT-56 that I bought on Ebay and
uploading it to hifiengine.com

Fixing a broken HP scanner.  (Fortunately, I have a back-up scanner for the
service manual project).  I think the opto-interrupter that tells the
computer that the scanner has travelled to the end of the bed is broken,
and I think I can hack something up to replace its function.

Writing code for the ESP32 based TTGO-Twatch-2020, which I'm using as my
"daily driver" watch lately.

Making a welding table out of a Harbor Freight wood-working table (mainly,
having a steel top made for it).

Making welding table clamps for the above welding table project.

"Restoring" a 21 foot steel pipe I found in the ground (!) to use as an
antenna mast.  I de-rusted the outside, welded up some holes, and got it
"more or less" straight.

I manage to keep busy.
