Very hard route but I'm happy. Beautiful place, friends....
I had good times in a few hard parts but in the crono (last 5kms) I only did a regular time... I guess that my body isn't to 100%.
Diamond drag engraving is surprisingly fun and easy.
I decided to buy a spring loaded diamond drag engraver and do some experimentation on feeds, cutting depth, stepover etc.
I ended up. 90 degree drag bit. tip flat estimated at 0.128mm, 0.1mm step over, fill crosshatch at 0 degree, 700mm/min feed speed.
Far better results than using a V bit, much less sensitive to the material not being totally flat and far far faster.
That is really sad to hear and see! Whitney is a great guy and I still think of him when I listen to Iron & Wine and other music he introduced me to.
Sending good thoughts and hope for improving your life Whitney!
Thanks for letting us know, Ric. ☹️
So, I got myself QuantAsylum QA-403 Audio Analyzer. Now I can make some simple analyses of amplifiers I build.
Screenshot – my CFA3smd something with HD800 headphone,
2Vrms into headphone. Probably room for improvements. But I’m satisfied and I’m not competent enough to make it better.
I doubt he'll see this, but back in the early headphone days, especially in the Bay Area, Whitney was a regular. I know plenty remember him from those early meets. Great guy and always incredible music suggestions. After peeling off, he reshowed in my world from this Stanford Medicine article - The Puzzle Solver. With today's HC birthday reminder I looked up his web site and see he's posted a few recent videos to his YouTube channel. He has had a very tough time with severe Chronic Fatigue Syndrome, also called Myalgic Encephalomyelitis (ME/CFS). Saying happy birthday Whitney, but also bringing those who were not aware up-to-date.
