Email mind control

From Kathyphrog:

This is strange…..

While sitting in a chair, make clockwise circles with your right foot.

While doing this, draw the number “6” in the air with your right hand.

Keep it up and read the end…..

Your foot will change direction… and be rotating counter clockwise. . .

Configuring it so it works just the way I want it. I spent almost 4 hours fiddling with UI-ish crap. But it’s important so…

Charging Zagi KR-1700AU batteries, Silicon didn’t help, new motor did, Being eaten alive!, A nice day

Charging Zagi KR-1700AU batteries

The Zagi Trick RC manual says, “SANYO RECOMMENDS CHARGING THE KR 1700AE CELL AT A RATE UP TO 1
AMP….SOME MODELERS REGULARLY CHARGE THEM FOR 40 MINUTES AT 2 AMPS.” This is simply not true. Sanyo’s recommendation is a fast charge of 2.6 amps. That is the exact same recommendation they give for their “fast charging” (4 mega-ohm) N-1700SCR battery, and their “high capacity” (16 mega-ohm) KR-1500AUL. The KR-1700AU has 17 mega-ohms of resistance. I now feel completely safe charging at a maximum of 2.5C… 4.2 amps… a 25 minute charge. I’m staying shy of the often recommended 3C charge because of the fairly high internal resistance in the battery. When I don’t need a speedy charge, I’ll keep it at 1C. I’ll do this for a while and then gauge (mostly by heat build-up patterns in the battery) how to modify this strategy.

See Sanyo.com or my flying homepage for references.

Silicon didn’t help, new motor did

I went out flying today with the spinner held on tightly with silicon glue. It didn’t work. I went through one battery, brought it in, tossed it with a second battery and it only went 50 feet before it started making the spinner’s-gonna-fall-off-any-second noise. FYI: the prop gets quieter and the motor spins faster, making a very quiet high pitched whir as it starts to slip. That’s the sign for you to prepare for a landing and start watching for the prop because then there’s this almost imperceptible clicky-poppy noise when the prop pops off. Now your electric wing is now a glider.

So I took the motor off and tried the Promaxx 7.2 volt motor. I bought this a while ago but never got to try it out. Actually, I’m glad I waited because swapping motors with my new motor mount was a snap… or rather a ‘zip’, pulling the velcro stays off and resoldering (with my snazzy-and-quick soldering gun). The new motor has a bit less power but it flew a LOT longer than the old motor, maybe 20 minutes per battery WOT the whole time! That’s pretty much in keeping with my style so I’m very happy with the new motor. I checked the temperature of the motor after 2 batteries and it was quite a bit cooler than the old motor. My temperature measurement is very scientific: After flying one battery on the old motor, the top of the motor (nearest the prop) was “Ow! I burned myself! [insert finger in mouth]” hot. After flying two batteries on the new motor, the top of the new motor was “Eww. I wouldn’t want to leave my finger on there too long!” hot. Using my handy-dandy temper-lee conversion calculator, those temperatures are 400 and 250 Fahrenheit, respectfully.

Now I have a motor I can rip apart for mad experimentation!

Being eaten alive!

I find myself going out between 5 and 7pm most of the time. The mosquitoes can me AWFUL at this time of the day! Today, I tried dousing myself in DEET bug repellent. Even with the repellent, I had to keep constantly walking around or I’d be chewed on by the bugs! I’ve got marks all over from where those little buggers got me!

A nice day

Julian gave this to me. It’s from several few weeks ago. I suppose I’m a tall fellow by some standards, yes?

Vitamins

So I keep hearing that the USDA’s food pyramid thingy and vitamin recommendations are “outdated”. Everybody who knows anything about vitamins knows that the USDA is behind on the times… So being a person with some desire to do the right thing, I tried to find out what vitamins I SHOULD take.

Nobody friggin knows.

vitamin A is 5,000 IU. no more than 10,000
vitamin C is 90 mg
folic acid, at least 400 micrograms (women only?)
vitamin B6 1.3 to 1.7 milligrams of
B12 is 6 micrograms
vitamin D is 5 micrograms
vitamin E 22-400 IU

vitamin K is 80 micrograms

I’m just going to keep taking Centrum. And when I start to feel sick, I’ll take extra Vitamin C like my dad demands I do; At least it makes him feel better.

PVPOA Announcements Mailing List

After months of working with committees , we’re just about ready to launch the PVPOA’s announcement-only mailing list. My real goal is to get a discussion mailing list going. We’ll get there… baby-steps. Baby-steps.

The State of Computers Today

from an exchange between TJIC and me.

>Mail is going wonky. Web page load times are way up. There may be
>some sort of huge worm/virus attack going on as well, according to
>some reports.

I’ve gone to maybe 15 people’s homes in the last 2 months to help them with computers. NONE of these people had any idea what a firewall was or what Windows Update was. Heck, I tried to make the analogy to my cousins that updating Windows was like changing the oil in your car… getting it done is really easy and you have to do it or you won’t have a car for long. I got what amounted to a blank stare from all of them, including the 17 and 15 year olds. I decided to set their computers to automatically go to Windows Update and not even tell them about it.

But then if I can convince these people to have their “oil changed” by me, I can do well…
