Personal black holes
Back from a control visit with my preferred eye surgeon (the pressure is under control, thank you), I realized that my eye had locked in the open iris position. Something like this.
For those conversant in f-stops, think f:1.2 (a mighty light gathering device). In medical terms, something more like this.
There’s a problem with that. Today, the sun was shining brightly, and my eye no longer responded by closing that same iris to a more suitable f-stop; say, f:22. Instead, my eyes were like black holes, sucking in the available photons. Yes, one can ride the city bus with their eyes closed.
Diligently, I found my way, through familiarity, to the relative peace provided by my cubicle. The option of sunglasses was available, but I’m not a fan of that Corey Hart song from my gentle youth, so I toughed it out. A beautiful corona around the computer screens. A beautiful blur around open doorways. Hours of exploration in a mysterious world, thanks to the wonders of opthalmology. Happily, the effect had diminished to a reasonable compromise by the end of the work day.
I’ve started work on yet another antenna project. This evening, I “populated” the circuit board for a small UHF preamplifier. The old (very old) coaxial cable hanging around in the basement isn’t going to be suitable for this job, so things are on hold for the next day or so while I try to track down a better cable choice; I have a few ideas. My soldering station is a vast improvement over the irons of old, and the actual wiring job took only a few minutes out of an otherwise quiet evening.
