00:02 rue_house frivilous things
00:02 rue_house http://www.ebay.ca/itm/271661910054
00:02 rue_house I hope I never need this
00:03 katsmeow-afk "Diastimeter Measurement"?
00:09 rue_house hmm
00:09 rue_house you dont have any extra keyboard time eh?
00:10 katsmeow-afk me?
00:10 katsmeow-afk atm, i have two in front of me, using both
00:10 katsmeow-afk what's on your mind?
00:12 rue_house I need some to help me put togethor a webpage for the weekend robotics
00:13 katsmeow-afk but we never have agreed on web design, and i dunno kids
00:23 katsmeow-afk my internets cable is warm
00:27 katsmeow-afk Also, since the late 2000s, South Korea has had a significant impact, with 8 of the top 10 girl groups by digital sales in the world originating there.
01:18 tsmeow-afk ponders a 8-bit computer museum called Jurascii
01:30 rue_house :)
13:20 any38483517 what i figure is if i take one complete 7A26, and the front ends from another 7A26, and put them into a 5A26 plugin, add a floating psu and analog level translator, i get dual 200Mhz differential floating inputs
13:20 any38483517 there's room for the 4 eq sections if turned sideways, and ganged, and turned by a servo instead of the front knob
13:21 any38483517 plenty of room for the floating psu and level shifter
13:22 any38483517 the hard part will be dc-to-200Mhz level shift over any more distance than the 7A26 is already set up to do
13:23 any38483517 would help tons to get rid of those two long readout boards, replacing them with a small avr and a couple CD4051
13:30 any38483517 as you can see, the 5A26 looks fine in a more modern 7603 with the 7B53 ==>> http://designerthinking.com/images/tekplugins/DSCF3243mc.jpg
13:30 any38483517 i mean other than the way Tek changed the size enough that the 5A26's need some physical stabilizers so they don't lean to one side
13:32 any38483517 bbl
14:30 any50613019 haw tout side
14:36 any50613019 35,000uf will drop 22v in 16ms when delivering constant 50amps
14:39 any50613019 the surge current to recharge the caps in 3ms at the top of the sine wave will be 266amps, plus the 50amps, or over 300amps
14:40 any50613019 a 300amp load for 3ms spaced 13ms apart is going to hammer the crap outa the genny
14:42 any50613019 300amp @ 240v = 96hp
14:43 any50613019 without a big enough flywheel, that might even break a connecting rod in the engine
14:45 any50613019 the answer is, once again, 3phase power, use a buck convertor to level the sine peaks from 240v-336v to a level dc of 230v, and draw a steady 35amps there
14:46 any50613019 even tho the 35amps will show up on different legs as the genny turns, it's 35amps, not 300, and it;s steady load as far as the engine is concerned
14:46 y50613019 s
14:49 any50613019 no capacitors needed , much, but it needs 3phase power
14:50 y50613019 wants to punch whoever decided all residential power must sinewave down to 0v, shutting off 120 times a second, and then overvolt to 160v 120x a se
14:52 any50613019 so what if the distribution system is ac, it's still 3phase out there in commercial/industrial land
15:08 y50613019 aaaaaaaarrrrrrrrgggggggggg
17:31 any27934609 so if i take a 1/2 mill bit (1/2" cutting and 1/2" shank), put 2 bearings on it, spin it with the drill, i can mash some steel down onto it with some allthread, and make a rounded notch in the steel?

19:12 katsmeow-afk meow?
19:14 tsmeow-afk gets some 14~12ice cold14~ wine coolers and hands one to Tom
19:15 katsmeow-afk hmm
19:15 tsmeow-afk offers Tom_itx some 1(m)&5(m)'s and tries to make friend
19:15 tsmeow-afk give
19:47 katsmeow-afk i dunno what to do, i need a mill to cut those slots, that's the only way to do this right
19:49 katsmeow-afk i can make something to spin a 1/2" mill side-cutting bit, i don't have a 1/2 shaft coupler
19:50 katsmeow-afk i feel like pounding my head on the desk

20:08 katsmeow-afk The spider is tight fitting buna n rubber for low "viabration transmittion"
20:19 katsmeow-afk The table is 9" in diameter with 8 equally spaced eattachment points with 1/4 - 20 treaded holes
20:32 katsmeow-afk k
21:17 rue_house I got bearings from ebay(?) that I didn't order.... (?)
21:21 Tom_itx put them to good use

23:31 rue_house those are much smaller aren't they?
23:32 any38099701 that what?
23:32 rue_house no point in making them in canada to sell, costs too much to ship them
23:32 any38099701 8mm ~= 3/16 , you can get 1/4 lovejoys
23:33 any38099701 umm,, 8mm ~= 5/16
23:33 any38099701 i can't find a rule i like, if i need to transpose measurement systems, i must flip the bloody ruler over :-/
23:33 any38099701 or use 2 of them
23:36 any38099701 if you hop on your boat and sail into Seattle and 1) buy soemthing, or 2) accept a gift, do you need to 1) go thru customs and/or 2) pay any bribe to get it home from the boat?
