08:57 rue_house if you have to replace a lens too, its verry not worth it
12:53 katsmeow i dunno why the puter went down, nothing else in the house is affected
13:04 Tom_itx it was tired
13:09 katsmeow i guess, but it hasn't been working all that hard lately
13:11 Tom_itx it didn't know what to do with all the free time
13:16 tsmeow ran into a connun
13:17 katsmeow if the 120vAC goes down, the charger/monitor won't be powered up to watch the 120vDC
13:18 katsmeow unless i do NOT optoisolate the monitor/charge circuits from the displays, and power each display by the battery it is displaying about from
13:19 katsmeow or i put in a 1 watt isolation transformer and driver to drive the display for each off each
13:20 katsmeow at 10ma per seg worst case is .35w for the 7-segs, plus there's the 4414, and isolation to drive the remote jack
13:21 katsmeow er. .56
13:21 katsmeow er. .64
13:21 katsmeow 8 displays of 7 segs @ 10ma per seg
13:21 katsmeow 1 watt
13:22 katsmeow to power them and the 4414 and more optoisolators
13:22 katsmeow assuming zero parasitic losses
13:26 katsmeow snow forecasted for tonite and tomorrow
13:27 katsmeow Friday Night
13:27 katsmeow Overcast with a chance of snow and a chance of rain after midnight.
13:27 katsmeow
13:27 katsmeow Saturday
13:27 katsmeow Overcast with a chance of snow, then a chance of rain in the afternoon.
13:28 katsmeow Saturday Night
13:28 katsmeow Partly cloudy. Low of 25F
13:28 katsmeow so hell is freezing over, get prepared
13:29 tsmeow feels sore, having done more real work yesterday than since getting the water in las
13:29 katsmeow and the roof garden
14:14 katsmeow-afk VD = abbr: "Valentine's Day", "Venereal Disease", "Video Display"
14:49 tsmeow-afk ponders taking a 7
14:50 katsmeow-afk 1) cutting it in half to put into a TM5xx slot, replacing the missing half with "tone" (frequency filter) controls, and two signal out (one to scope, one to freq counter)
14:51 katsmeow-afk B) cutting it in half, adding the freq contouring controls AND a freq counter, and leaving it as a 7000 series plugin
14:52 katsmeow-afk the fun thing is it's a dual channel natively, so i can display signal on one channel and onscreen markers with the otehr channel, and use the oscope on-screen display for all the numbers
14:54 katsmeow-afk by eliminating one input off the 7A18, i can free up ~2/3 of the plugin's front face, and add a jack for external complex freq shapeing
14:55 katsmeow-afk with an avr, i can maybe add some programmable filter, with half the 7A18 removed, there would be space
14:56 katsmeow-afk and with the avr, i don't *need* the setting of the timebase, i can deduce it from the gate signal, as well as generate a trigger signal
14:58 katsmeow-afk i keep wracking my feeble brains to make this all fit into a 250Mhz dual channel 7A26, but i run out of front panel space, and would need to add more signal/marker mux circuit at 250Mhz
14:59 katsmeow-afk and who wants to trash a 7A26 when a 7A18 is good for 80Mhz?
17:21 katsmeow-afk the colossal deep ocean squid is twice as long as a school bus, but can hold only half as many kids
20:13 rue_house hmm
20:13 rue_house maybe build a new one
20:32 katsmeow-afk a new squid?
23:16 katsmeow-afk <cough>
23:40 katsmeow-afk As a result, Bir Tawil is one of the few land areas of the world which is not claimed by any recognised state. LETS PLANT ROBOTS THERE!!!!
