13:38 katsmeow-afk i just figured out how to make a 60hz ac motor be variable speed, or speed controlled as the load varies
13:39 katsmeow-afk with no energy storage, so high freq, and i feed complete 60hz sine waves to the windings
13:39 katsmeow-afk err, NO high freq
13:41 katsmeow-afk using only triacs (and their dip-6 drivers and some glue logic) good for 60hz
13:41 katsmeow-afk unmodified motors
13:42 katsmeow-afk it crossed my lil mind as i was thinking of the $10 one hp motor with the free variable diameter pulley
13:43 katsmeow-afk if i am thinking correctly, i can set it for 3600 rpm and vary it +/- 600 rpm easy, and +/- 1200rpm without much if any cogging

16:54 katsmeow-afk It's a common occurrence. You call customer service and you're put on hold. "Please hold for the next available representative. Someone will be with your shortly."

21:33 katsmeow-afk interrupting and stopping the conversation, same as i did in #RoboTics
21:33 Tom_itx i ran outta comments about it really

21:39 Tom_itx that's alot of fence
21:40 katsmeow-afk it's just very time consuming to tie the new to the old 4x every 1.5 feet for 300ft
21:41 Tom_itx you have to leave the old up?
21:41 katsmeow-afk and i put the small-opening fence on the 2x 8ft driveway gates too

21:46 Tom_itx did you get any further on your little motor experiment?
21:46 Tom_itx i haven't seen that page lately
21:48 katsmeow-afk i got a decent centing bit, and moved a sittin' stool downstairs infront of the drillpress, to mount the TIP35/36's on heatsinks, for the psu that powers the motor
21:48 katsmeow-afk if that counts
21:49 Tom_itx it does
21:49 katsmeow-afk but my feets are in a lot of pain (i have spinal cord damage affecting hind feets) after fence work, so i am sitting down in a real chair

21:59 katsmeow-afk afaik
22:00 Tom_itx ironic thing is they are rebuilding a bridge/dam here and there's barely any water going thru it right now on the arkansas river
22:01 Tom_itx last year there were weeds growing in the middle of the river
22:01 katsmeow-afk "When you consider that a typical tow on the upper Mississippi or Ohio Rivers has 15 barges, a one-foot loss of draft will decrease the capacity of that tow by 3,000 tons," Allegretti said.
22:02 katsmeow-afk He said it would take 130 semi trucks or 570 rail cars to haul the freight unloaded by one large barge under those conditions.
22:02 Tom_itx just more higher prices
22:03 katsmeow-afk all i can get for tv here is ABC, and they don't cover anything important

22:08 Tom_itx that must be one damn deep river
22:09 Tom_itx or it's a dirt road now
22:09 katsmeow-afk i wonder why they can't let the water flow backwards thru Cleveland , out of Lake Whichever, and into the Miss?
22:10 katsmeow-afk A study of 92 developing countries shows that � as higher incomes drive improvements in diets around the world � as much as an additional 5,200 cubic kilometres of fresh water may be needed annually for agriculture alone by 2050.
22:10 Tom_itx maybe they feel they need to keep it?
22:10 katsmeow-afk in the Great Lakes? are they low too?
22:11 Tom_itx oh i have no idea
22:11 katsmeow-afk While the idea of bulk water exports to thirsty regions of the United States raises nationalistic ire among Canadians, effective treaties and close relations suggest that disputes over waters that compose nearly 40 percent of the boundary between the two countries can continue to be resolved amicably.
22:14 katsmeow-afk Alex Sosnowski, expert senior meteorologist for AccuWeather.com. And while droughts tend to be a temporary setback, longer-range forecasts are troublesome. Sosnowski says he is anticipating an El Ni�o weather pattern next year, which would mean below-normal snowfall and above-average temperatures.
22:15 Tom_itx well it concerns me
22:16 Tom_itx i have seen our river go from the absolute fullest i've ever seen it to nearly dried up within a 4-5 yr span
22:17 tsmeow-afk
22:17 Tom_itx i'm goin afk. my head hurts
22:18 katsmeow-afk you wouldn't think of Fla as a desert, but over the last 50 yrs the land area tehre has gone up drastically as ground water is pumped out
22:19 katsmeow-afk lakes all over are dry, water levels drop from 5ft over ground to 5ft under ground, exposing sand
22:20 katsmeow-afk water levels were also running low in the Mississippi River south of New Orleans, according to the U.S. Army Corps of Engineers. That was allowing saltwater to begin working its way upriver, which could threaten some water supplies.

22:45 katsmeow-afk from Forbes : Boeing�s $460 million contract is geared towards development of its commericial spaceflight systems
22:46 katsmeow-afk it's Boeing, maybe they mean comical
22:47 katsmeow-afk What people don�t appreciate, when they picture Terminator-style automatons striding triumphantly across a mountain of human skulls, is how hard it is to keep your footing on something as unstable as a mountain of human skulls. Most humans probably couldn�t manage it
22:50 katsmeow-afk Battlebots, on the face of it, seem like they�d be among the most dangerous robo-soldiers. But it�s hard to feel threatened by something that you can evade by sitting on the kitchen counter and destroy by letting the sink overflow.
