00:01 katsmeow since it isn't class 2, if i were you i'd put them on some roofing tin you shape to be pleaseing to the eye and containing of any small fires in the strips
00:02 rue_house I found a health chart, it says I need B12, 6, 2 and zinc
00:02 katsmeow ok
00:03 rue_house I'm sorry kat, It might be me, but I cant parse that last statement
00:03 rue_house I think my brain is failing, the errors are getting worse
00:03 katsmeow the "B12, 6, 2 and zinc" ? or the "ok" ?
00:04 rue_house the since...
00:04 katsmeow the led strips are high power than class 2 electrical wiring
00:04 rue_house ah
00:04 katsmeow and yet, they are not in code-approved enclousures
00:05 rue_house plug in low voltage = do what you want
00:05 katsmeow so at least put them on a fireproof backing, and roofing tin came to my mind
00:05 katsmeow it's not only low voltage, the current is specified also
00:05 rue_house I wonder if they can start a fire
00:05 rue_house hmm
00:06 katsmeow any of the resistors can blow flaming chunks
00:06 rue_house at 20mA?
00:06 katsmeow 10v 20ma is 1/4 w, i have seen 1/4 w R get smokey and pop
00:07 katsmeow it wasn't normal
00:07 katsmeow but it's happened
00:07 rue_house I want to be awake and I'm really tired
00:07 rue_house they use 3 leds in series with a resistor
00:07 rue_house white, prolly almost 2V
00:07 katsmeow normally, cfl don't smoke up a room and blow flaming chunks, but they do smoke and they must be in ceramic bases in usa
00:07 rue_house so, 6V @ 20mA
00:08 rue_house I'v seen lots of cfl melt down
00:08 rue_house its the leading cause of me smelling something burning in the house
00:08 katsmeow i have had several that would have set the house afire if not for being in a ceramic base
00:29 katsmeow gnite
01:11 rue_shop3 gnight
09:47 ^kat^ so if the reason for a cpu is to perform tests, perform math, why do those operations and tests need to be done centrally?
09:49 ^kat^ high performance gpu video cards now do most 3D rendering math separately from the central processing unit
09:50 ^kat^ it's been a known trick to memory map math lookup tables
11:13 at^ looks at
11:15 ^kat^ typical Vhigh input on a 74HCT245 is 1.6v(?!) and a low is typical 1.2v , that's a 0.4V spread..... SSTL2 is a 0.6v spread from Vhigh to Vlow, so SSTL can drive *this* 74HCT chip?!
11:20 ^kat^ how to make a 7404 feel more important: dress it up in a DHVQFN14 package
11:22 ^kat^ some of the older data sheets are listing tighter Vranges than the new sheets
11:24 ^kat^ the HCT14 is listed as 3.14Vhigh and Vlow is 1.89 , which is a 1.25Vspread
11:26 ^kat^ somehow, thinking of a chip with 41ns propogation delay and a 125ns slew rate as a 7414 is oxymoronic
11:29 at^ ponders an 8-port ram mo
11:29 ^kat^ with 8 address busses
11:55 ^kat^ Unless otherwise stated, all computer programs are in PDP-6/10 assembly language.
12:01 ^kat^ �The average PMIC in a
12:01 ^kat^ smartphone has more
12:01 ^kat^ than 20 power supply rails
12:01 ^kat^ within a quarter of a square
12:01 ^kat^ inch.
21:35 ^kat^ one giant plain milk chocolate bar, please, and a shipping crate of rice krispie treats
21:37 at^ has a 20mm spindle with ER16 collet chuck, mounted in bearings, and a worn out paw from applying the 2lb press to many ball bearings to be inside id
22:35 ^kat^ idea: model a robot on The Good Dinosaur
23:47 rue_shop3 hey
23:48 katsmeow hey
23:48 rue_shop3 8 port ram!?
23:49 katsmeow well, it would make coprocessing faster on one ram module
23:51 katsmeow if the ram is 7ns and the cpus are 100ns , emulating the 8 ports seems like a grand idea
23:51 katsmeow 8cpu x 7ns ram = 56ns, you have 40ns to play with
23:52 katsmeow http://designerthinking.com/condensation/condensation.html
23:57 Tom_itx rain or just humidity?
23:57 katsmeow humidity
23:57 katsmeow everything is as wet underneath as on top
23:57 katsmeow cept for the tin roof itself
23:58 katsmeow you see the driping water on pvc conduit and the bundles of romex, up as high as possible 1.5 inches below the tin roof? from that point down, everything is soppy
23:59 Tom_itx http://www.intellicast.com/National/Radar/Current.aspx?animate=true&location=USKS0523
23:59 Tom_itx pretty soppy here too
23:59 Tom_itx only it's likely to freeze in place
