| B0101 | azonenberg: Have you done metal deposition by metal evaporation before? | 22:07 |
|---|---|---|
| azonenberg | B0101: Yes, but not in my own lab | 22:08 |
| azonenberg | it was using a professionally made tool intended for coating SEM samples | 22:08 |
| azonenberg | the process is simple enough that i'm confident i could build one given the time | 22:08 |
| soul-d | this looks like a channel that can apreciate a random plot of data http://i.imgur.com/dJJTgWM.jpg | 22:13 |
| soul-d | now on break with coffee :P might try somthing with countrymap and contour ploting ater on now back playing with finincial data | 22:15 |

| soul-d | more in the osciloscope line :P you see any global warming patern their azon ? :P | 22:16 |
| azonenberg | soul-d: what are you ploitting? | 22:17 |
| soul-d | thats 100 year data of average daily temps | 22:17 |
| soul-d | last plos is avr min max | 22:17 |
| soul-d | color plot botom is 1901 x = days in year where 0 is jan | 22:19 |
| soul-d | http://imgur.com/a/W1YzV | 22:20 |
| soul-d | just finished fist finencial test | 22:20 |
| soul-d | top plot is generated in python from 1minute data | 22:20 |
| Action: B0101 does not know why 1 inch wafers cost SGD $25 | 22:52 | |
| diginet | do you have to use gold for SEM coating? | 23:24 |
| diginet | I've thought about trying to acquire a SEM, but if you have to use gold, that's kind of a deterrent (expensive consumables/cost to operate) | 23:24 |
| Sync_ | with a small amount of gold you can go a long way | 23:27 |
| Sync_ | it's not as expensive as you think | 23:27 |
| diginet | oh, I know, it just feels. . .well, wrong to waste it :P | 23:29 |
| Sync_ | wut | 23:29 |
| diginet | I have weird hangups about consumables in general | 23:29 |
| diginet | like I feel guilty about buying food because it feels like a waste of money (which is clearly absurd) | 23:29 |
| diginet | like I refuse to ever get helium balloons, the concept just bothers me, since helium is such a finite resource | 23:30 |
| Sync_ | then you should never weld tig | 23:30 |
| Sync_ | using helium as a shielding gas makes welding Al such a charm | 23:31 |
| diginet | why not Ar? | 23:31 |
| Sync_ | lower arc temperature | 23:31 |
| Sync_ | or rather less heat input | 23:31 |
| Sync_ | but yeah liquid helium is getting quite spendy | 23:35 |
| diginet | that legitimately worries me, once we use up helium it's gone. Our neon, for example, comes from the atmosphere, and goes back into it when we're done, in theory that can be renewed | 23:41 |
| diginet | but not helium | 23:41 |
| Sync_ | we still get he from natural gas wells | 23:48 |
| diginet | I know, but we are depleting it faster than it is being renewed | 23:58 |
