Back
[16:18:40] <rue_shop3> there is an amount of grinder cutting of hot water tanks that makes me think a plasma cutter would be of value
[17:15:28] <Tom_itx> linuxcnc supports plasma cutters
[17:15:37] <Tom_itx> several guys have them
[17:17:00] <Tom_itx> oh but you want to wave it around in the air wildly
[20:33:30] <katsmeow> soap is a 4-letter word
[20:36:09] <katsmeow> U.S. oil and gas executives bet big on 2016 Republican presidential candidate Jeb Bush - they donated more to his White House run than to all of his rivals combined .... He drew more than $2 million from the chief executive officers of companies like Exxon Mobil, Halliburton, Kinder Morgan, and Chief Oil & Gas in 2015, making up about 56 percent of all the industry’s contributions to the race so far
[20:37:00] <katsmeow> so if Shrub 3 wins, all oil pipelines will be built and all wells will be drilled
[21:04:30] <rue_shop3> hey kat
[21:05:10] <rue_shop3> electric cars aren't going to be big in the states this year
[21:07:06] <katsmeow> ok
[21:07:51] <katsmeow> except for rich people who can afford non-lead batteries, they never have been big
[21:08:27] <katsmeow> swapping out the lead acid batteries every year gets *real* pricey per mile
[21:21:38] <katsmeow> meter!
http://www.ebay.com/itm/221524041592
[21:22:08] <katsmeow> bezel! nope.
[21:23:07] <rue_shop3> how can they say that when its not even the presidents decision
[21:23:31] <rue_shop3> Shipping:
[21:23:31] <rue_shop3> Does not ship to Canada
[21:23:44] <rue_shop3> I have to buy from china
[21:24:02] <katsmeow> president also says "no oil shipments FROM Canada"
[21:24:31] <katsmeow> i think his prices are cheaper than from China, to me anyhoow, his s&h is free
[21:24:52] * katsmeow offers to relay if the shipping is cheaper?
[21:25:45] <rue_shop3> how long does it take to bake ants out of an oven?
[21:26:33] <katsmeow> not long, they'll leave pretty fast till it cools off again
[21:46:20] * ^kat^ put on some Marlene dietrich on the laptop, and this irc dropped!
[22:53:29] <^kat^> [22:28] <^kat^> can 60x or 80x sizes of leds be soldered to the *edge* of pcbs?
[22:53:30] <^kat^> [22:28] <^kat^> like one solder to the top and one to the bottom, across the edge?
[22:53:57] <^kat^> do those small sizes make useable brightness?
[23:05:06] <rue_shop3> hmm
[23:05:38] <rue_shop3> I think you could
[23:06:00] <rue_shop3> k, I need to make supper and fix the chair of doom
[23:08:17] <rue_shop3> magnetic pulses from a neuron, I wonder how strong the pulse is
[23:09:37] <rue_shop3> well, whats the current
[23:09:47] <rue_shop3> hmm, whats the energy, joules, and time
[23:12:25] <rue_shop3> pulse time looks about 5-10ms
[23:14:02] <^kat^> you got pickups?
[23:15:00] <rue_shop3> according to this, the brain dissapates about 20w
[23:15:53] <^kat^> so wonder i keep sweating
[23:16:13] <rue_shop3> A typical neuron fires 5 - 50 times every second.
[23:16:17] <rue_shop3> ""
[23:16:38] <rue_shop3> "The human brain has about 100 billion of them. Each neurons fires (on average) about 200 times per second"
[23:16:46] <rue_shop3> ok, ball parks
[23:17:17] <rue_shop3> so lets say we have 100G neurons
[23:17:50] <rue_shop3> so 20P firings/second
[23:17:54] <rue_shop3> at 20w
[23:18:01] <rue_shop3> hey, nice numbers
[23:18:22] <rue_shop3> so, ballpark
[23:18:54] <rue_shop3> each firing is about 1/1P w
[23:19:17] <rue_shop3> ...
[23:19:40] <rue_shop3> k, M, G, T, P
[23:19:50] <rue_shop3> did I get the multiplier right?
[23:19:59] <rue_shop3> 100G * 200
[23:20:07] <rue_shop3> 20000G
[23:20:12] <rue_shop3> 20T
[23:20:14] <rue_shop3> oh
[23:20:26] <rue_shop3> so 20T firings/sec
[23:20:37] <rue_shop3> kat...
[23:20:43] <^kat^> rue...
[23:20:51] <rue_shop3> work with me here...
[23:21:01] <rue_shop3> 20T firings/sec, right?
[23:21:10] <rue_shop3> at 20w
[23:21:16] <^kat^> i think many people have much lower firings
[23:21:32] <^kat^> trying to find "in den kasernen" lyrics
[23:21:32] <rue_shop3> lets not factor in the stupid people
[23:21:48] <rue_shop3> 1/1T watt/firing
[23:21:55] <rue_shop3> k, M, G, T
[23:22:00] <rue_shop3> m, u, n, P
[23:22:16] <rue_shop3> so each firing is 1pW
[23:22:22] <rue_shop3> ballpark
[23:22:36] <rue_shop3> 5-10ms
[23:22:40] <rue_shop3> sanity check
[23:22:49] <^kat^> quite economical, but it would need to be low power, it's cooling system is pretty poor
[23:23:13] <rue_shop3> 5ms works with 200Hz
[23:23:18] <rue_shop3> ish
[23:23:59] <rue_shop3> so, 1pW, 5ms
[23:24:18] <rue_shop3> if I dont know the voltage, I dont know the current
[23:24:53] <^kat^> voltage and current will be the level of chemical ion transit
[23:25:22] <^kat^> with microscopic emitters and recievers
[23:26:19] <rue_shop3> An action potential is part of the process that occurs during the firing of a neuron. During the action potential, part of the neural membrane opens to allow positively charged ions inside the cell and negatively charged ions out. This process causes a rapid increase in the positive charge of the nerve fiber. When the charge reaches +40 mv, the impulse is propagated down the nerve fiber
[23:26:21] <rue_shop3> ""
[23:26:27] <rue_shop3> KAT ITS A FREAKING TUNNEL DIODE!
[23:26:38] <^kat^> heh'
[23:27:03] <rue_shop3> is that not the behaviour of a tunnel diode breakover?
[23:27:29] <^kat^> afaik, the silicon doesn't move
[23:27:42] <^kat^> it opens no holes in itself
[23:27:57] <rue_shop3> After the neuron has fired, there is a refractory period in which another action potential is not possible. During this time, the potassium channels reopen and the sodium channels close, gradually returning the neuron to its resting potential.
[23:28:03] <rue_shop3> ""
[23:28:39] <^kat^> yas
[23:29:03] <rue_shop3> so about 95mv
[23:29:06] <^kat^> if you can keep the cell recharging, or unable to recharge, it is anethesized
[23:29:14] <rue_shop3> 95mV 1pW 5ms
[23:29:28] <^kat^> freaking low current
[23:29:31] <rue_shop3> what is the current
[23:29:45] <^kat^> literally a few atoms
[23:30:58] <rue_shop3> 5e*10-15 J
[23:31:09] <rue_shop3> 5e*10^-15 J
[23:31:30] <^kat^> -15 , ouch
[23:32:14] <rue_shop3> how do I go between joules, volts and amps
[23:32:22] <^kat^> i don't
[23:32:33] <rue_shop3> cmon, its a capacitor discharge
[23:32:59] <^kat^> 10-15 ~ 2^-49
[23:34:07] <rue_shop3> whats 10^-15
[23:34:10] <rue_shop3> p? f?
[23:34:33] <^kat^> so much for usng 48bit binary fixed integers in Tiggr, you found stuff nearly at 50bits
[23:34:49] <rue_shop3> 95mV 1pW 5ms
[23:34:58] <rue_shop3> 5e*10^-15 J
[23:35:36] <^kat^> femto
[23:35:45] <rue_shop3> so 5fJ?
[23:36:21] <^kat^> i'll agree with you for lackof any other data
[23:36:33] <rue_shop3> 5e*10^-15 J
[23:36:38] <rue_shop3> 5fJ?
[23:36:52] <^kat^> deja vu
[23:37:22] <rue_shop3> on the nose, ok
[23:38:42] <rue_shop3> ok I think the answer is .00111pF
[23:38:47] <rue_shop3> wait, thats not the answer I want
[23:39:02] <^kat^> 2^48 = 281T , 1/281T = 3.55e-15
[23:39:21] <rue_shop3> whats that?
[23:39:26] <^kat^> math
[23:39:30] <rue_shop3> for?
[23:39:31] <rue_shop3> of?
[23:39:38] <^kat^> seeing if 48bit was enough
[23:39:47] <rue_shop3> I dont know if your helping me or working on your own thing
[23:41:20] <^kat^> my own thing
[23:41:28] <^kat^> YOU SAID TO WORK WITH YOU HERE
[23:42:25] * ^kat^ wanders off to find if Dietrich was singing sheize in In Den Kasernen
[23:45:16] <^kat^> it's scarey to think all of human knowledge relies on some ion exchanges in biobrains that die, and harddrives that die too
[23:47:10] <rue_shop3> arg, if I know this I can work out what the impulse energy is and know what kinda coil I need to pick up on it
[23:47:17] <rue_shop3> and how much signal I'll get
[23:47:32] <rue_shop3> 95mV 1pW 5ms
[23:50:03] <rue_shop3> so 1pW * 5ms = ____ joules
[23:50:35] <rue_shop3> so 1pW * 5ms = 5e-15 joules
[23:50:58] <rue_shop3> if I take it as a square pulse, which its not,
[23:51:44] <^kat^> more like a fast noise burst, we'd still hear it as a very short click
[23:52:25] <rue_shop3> 1e-11 amps
[23:52:33] <rue_shop3> so 10pA?
[23:53:33] <rue_shop3> ok, it'll be more, not by a lot
[23:54:49] <rue_shop3> If all the neurons in the human brain were lined up, they would stretch 600 miles
[23:54:50] <rue_shop3> ugh
[23:55:22] <rue_shop3> 965606m
[23:56:34] <rue_shop3> 9.65606e-06m
[23:56:56] <rue_shop3> 0.0096mm
[23:57:33] <rue_shop3> so I have a peice of wire, thats 0.01mm long, and has a 10pA pulse go thru it
[23:58:06] <^kat^> there's opamps for that
[23:58:29] <^kat^> if yo breathe n them, it screws them up,, you cannot put their inputs on pcb
[23:59:00] <^kat^> unless they are ceramc, baked, and coated before coming out of the bake oven, and then calibrated after that
