6.145 tech, meeting

Monday 04/28/2025

Took an early morning walk. Picked up a prescription at CVS, which turned out to be spironolactone, the drug that I cut back from 1/day to 3/week some time ago. So I still have not only 20 or so still in the working bottle, but discovered that I also had another full bottle in the spare-pills drawer. ‘Scuse me a sec…

switches over to CVS.com and turns off auto-refill for that drug…

Now then. At 11 I went down to the auditorium and set it up for a test of monitor speakers. This was because Bert’s friend Larry was going to come by and give advice at 1pm. The problem at hand was that professional musicians are used to have monitor speakers that point back at them so they can clearly hear what they sound like. When I tried to do that for the Keller Sisters, anytime I got the monitor up loud enough to suit them, I would get feedback.

While setting up I noticed that the feedback frequency was very low. Just short of feedback the sound would get deep and echo-y like talking into a deep well. So ok if it wants to feed back in the low tones, let’s cut the low tones. The sound board has a four-band equalizer for each mic, and I just rolled the 100Hz knob over to zero. Bingo, no feedback.

When he got there, Larry concurred with what I’d done. He had some other suggestions, and told me some great war stories about being sound man for bands. After he left I had Jerry come down and try it out, he’s the one CH performer who wants a monitor. We got it to work for him, too.

Then I put everything away.

At 4pm was the Common Spaces Advisory Group. Patty and I presented our proposal for the 11th floor tv area. Everybody seemed to like it. Rhonda said she would start getting prices.

Mary Beth, head of the Treasure Trove (gift shop) asked me to look at a donated iPad, so now I have to figure out how to reset to factory, an iPad for which the former owner is no longer able to remember anything like a passcode. I looked it up and will do this tomorrow.

Also an old Kodak Carousel slide projector. My goodness, all through the 60s to the early 00s, we used our Carousel a lot. Been 20 years since I touched one. The owner of this one had stashed two spare bulbs in the box. Good thing. The one in the projector burned out as soon as I turned it on. Power switch on, flash, dark. And the first spare was also kaput. But the 2nd spare worked. Bulbs cost $25 for 2, on amazon. The projector sells on eBay for around $30-$40.
