12:35 AM rue_house: hmmm
12:37 AM rue_house: so I want a solution for small 120VAC pilot lights
12:37 AM theBear: solution ? whatchoo talkin bout willis ? i know ovens and fridges tend to have small mains rated lamps in em
12:40 AM rue_house: small indicators for things like the power on lamp for thepower supply
12:40 AM rue_house: bench
12:43 AM theBear: pfft, even guys like us gotta get with the times maaaan... resistors/caps and leds is the way of the future.... flickerey neons and hot little 5-15w incandescants are so last-century :)
01:15 AM jesseg: rue_house, you mean like little quarter watt neon lamps?
01:17 AM rue_house: but maybe led?
02:52 AM rue_bed: just want to know the power is on
02:52 AM rue_bed: something about 10cm long, maybe 8mm dia? max?
02:53 AM rue_bed: peak on 120 is 170
02:53 AM rue_bed: 2.5w by just resistance to drop that
04:37 AM Jak_o_Shadows: rue_bed christmas lights
04:38 AM Jak_o_Shadows: I have seen christmas lights that don't have a transformer.
05:30 AM Tom_L: rue_bed, regular led -> diode -> resistor
05:31 AM Tom_L: the diode will keep from blowing out the led junction on AC crossover
05:52 AM theBear: mmm, i almost mentioned the diode, but i was trying to sound like a smartass, and would expect rue to know better
06:18 AM theBear: so a foot of crappy inappropriate cable between a 75r video source and proper cabling or terminator/receiving something, can that look like blurring (as opposed to classic reflectey sharp ghosting) ?
06:44 AM veverak: deshipu: needed holder for tote robot
06:44 AM veverak: got an idea

06:44 AM veverak: :)
06:45 AM deshipu: I'm using this: https://www.aliexpress.com/item/Phone-holder-MEIYI-601-Long-Arm-Flexible-360-Roating-for-universal-phones-white/32636494963.html
06:48 AM veverak: interesting
06:48 AM veverak: well, worst case scenario I will make tentacle monster out of those...
07:07 AM deshipu: they are quite useful with crocodile clips as third hand'
07:50 AM z64555: deshipu: that link is much too long, IRC cuts it off
07:51 AM z64555: err
07:51 AM z64555: not deshipu, veverak
07:51 AM * z64555 needs to get the coffee maker going
07:52 AM deshipu: z64555: it's fine, you only need the part up to .html
07:53 AM deshipu: z64555: the rest are his saved search settings
07:54 AM z64555: guess they do that to avoid using cookies
08:01 AM deshipu: to get the data over domain boundaries
09:02 AM rue_bed: you only need to post up to the ?

09:34 AM rue_house: everything after that is his aliexpress browse history, username, password, and his credit card information.

11:09 AM veverak: upgrade to 6 leg version
11:09 AM veverak: :)
11:37 AM jesseg: anniepoo, hey how's it going... Haven't heard much from you since your printer parts arrived :D
01:05 PM tttb2 is now known as tttb
01:20 PM anniepoo: Hey jesseg - printer's assembled, did some work on the snail last night
01:20 PM anniepoo: 8cD the shell's become a mini-project on it's own. But that's the point of the snail, to learn stuff I'll need later
01:23 PM jesseg: I don't know anything about the snail...
01:23 PM jesseg: Is that related to the 3D printer?
01:23 PM anniepoo: only vaguely
01:23 PM anniepoo: I'm building a robotic snail, just out of hackerishness
01:24 PM anniepoo: we needed a 3D printer for some project at the Elgin Works, so I bought one, quickly assembled it, and we're using it
01:24 PM anniepoo: 8cD my sculptor/foundryman's sitting to my right, sanding on the parts
01:25 PM jesseg: lol wonderful
01:25 PM jesseg: what sort of drive mechanism are you using for the snail? a life-like rippling flexible rubber surface? or wheels?
01:25 PM anniepoo: treads
01:25 PM jesseg: ahh gotcha
01:26 PM jesseg: it'd be interesting to build one with real snail like traction system.. it'd take a very special strong but flexible jelly like rubber
01:26 PM jesseg: but it could be completely water proof :D
01:33 PM anniepoo: electrostatic
01:35 PM Tom_L: electrofying!
01:36 PM jesseg: Huh?
01:37 PM anniepoo: hang on

01:38 PM anniepoo: http://www.ijaiem.org/Volume5Issue4/IJAIEM-2016-04-06-10.pdf
01:40 PM jesseg: ahh cool
01:49 PM anniepoo: I originally was going to do ripple motion, but it'd be inefficient
01:50 PM anniepoo: (not that treads aren't, but the treads have lots of max specific tractive effort
10:34 PM zhanx: Evening
10:35 PM ace4016: ahoy
