| ybit | meh, don't worry about it, just grabbed them with my uni's proxy | 07:03 |
| * ybit can't access "A scanning tunnelling microscope with a piezoelectric-driven inertial slider" though.. | 07:07 | |
| ybit | grabbed the first assuming i could get the second, guess i won't assume again, and google scholar can't even find the paper | 07:08 |

| Trooem | what exactly are you guys doing and what is your ultimate goal (and what is your advantages in it?) | 08:27 |
| Trooem | ? | 08:27 |
| Trooem | your current projects i mean....... | 08:27 |
| Trooem | i'm waiting on my software to develop and finish up in next few days... the programmer is an asshole.. | 08:28 |
| ybit | stm software: http://gwyddion.net/ http://gxsm.sourceforge.net/ http://www.e-basteln.de/index_s.htm | 08:36 |
| ybit | Trooem: acquiring lab equipment to build stuff and experiment outside of uni. ultimate goal is to make some type of contribution to the greater conciousness of humanity | 08:40 |
| kanzure | Trooem: the goal is to make transhuman tech. so i've been working on skdb so that others can make the same tech too without a lot of effort. | 08:40 |
| Trooem | ah ha! so it was all related to h+. awesome. | 08:41 |
| * ybit wants "Chemically Tunable Nanoscale Propellers of Liquids" and "Powering an Inorganic Nanodevice with a Biomolecular Motor" | 08:43 | |

| kanzure | ok i called him and talked with him | 11:21 |
| kanzure | rawr you will be assimilated | 11:21 |
| -!- mason_l is now known as mason-l | 11:24 | |
| genehacker2 | are you trying to assimilate him or join the hive? | 11:34 |
| genehacker2 | seems more oriented to electronics | 11:37 |
| genehacker2 | but it might fulfill our needs | 11:37 |
| kanzure | well if you look at code.bildr.org he's basically doing what skdb mostly already does | 11:38 |
| genehacker2 | so assimilate him into skdb or join him on bildr? | 11:39 |
| genehacker2 | so what about tooling dependencies? | 11:39 |
| kanzure | what about them? | 11:39 |
| genehacker2 | he doesn't have that | 11:39 |
| genehacker2 | does skdb have it? | 11:39 |
| kanzure | yeah | 11:39 |
| kanzure | skdb is meant to be the brains behind stuff like bildr.org | 11:39 |
| genehacker2 | is it usable? | 11:39 |
| kanzure | bildr.org isn't | 11:40 |
| kanzure | but you can do stuff with skdb, yes | 11:40 |
| kanzure | skdb includes a full CAD geometry kernel, remember? | 11:40 |
| genehacker2 | no | 11:40 |
| kanzure | well.. it does. | 11:40 |
| genehacker2 | so can I make stuff in some skdb cad program? | 11:41 |
| kanzure | no you make stuff in other CAD programs, skdb can import those CAD files | 11:41 |
| genehacker2 | ok | 11:41 |
| genehacker2 | so what else does skdb do? | 11:42 |
| genehacker2 | don't you have matweb data on there? | 11:42 |
| kanzure | no matweb is not in skdb | 11:42 |
| genehacker2 | or materials data? | 11:42 |
| kanzure | there is a little materials data but not a lot | 11:42 |
| kanzure | i think there's some friction information somewhere? | 11:43 |
| genehacker2 | friction information is useless in the real world | 11:43 |
| genehacker2 | friction depends on humidity, temperature, dustiness, whether or not you have touched the pieces in contact, and many other factors | 11:44 |
| kanzure | well you asked | 11:44 |
| genehacker2 | friction is a value that must be determined in the environment that the equipment operates in | 11:44 |
| kanzure | just look around: | 11:44 |
| kanzure | http://adl.serveftp.org/skdb/ | 11:44 |
| genehacker2 | alloy composition of various alloys would be good to add | 11:45 |
| kanzure | there's even a readme file to figure out what the files are all about | 11:45 |
| genehacker2 | and also heat treatment data | 11:45 |
| genehacker2 | though I am yet to find heat treatment data in a good form | 11:46 |
| genehacker2 | WHAT? | 11:48 |
| genehacker2 | you don't even have a list of various materials processing techniques in packages? | 11:48 |
| kanzure | http://adl.serveftp.org/skdb/processes.yaml | 11:48 |
| genehacker2 | so I have a bunch of notes with formulas for various materials processing stuff in them | 11:50 |
| genehacker2 | argh | 11:50 |
| genehacker2 | your processes file is annoying | 11:51 |
| kanzure | why? | 11:51 |
| kanzure | you're not supposed to read it anyway.. skdb is supposed to load it up | 11:51 |
| genehacker2 | it just is | 11:51 |
| genehacker2 | I can't tell if you're using a geometry classification system | 11:52 |
| kanzure | a what? | 11:52 |
| kanzure | these are processes not geometries | 11:52 |
| genehacker2 | different processes can make parts of varying geometric complexity | 11:53 |
| strages | just thought you'd all like to know about that website. yeah it's new and doesn't have a lot but they're looking for help populating the site | 11:53 |
| genehacker2 | there are some systems for determing this | 11:53 |
| genehacker2 | anyway if you can find a good alloy composition database | 11:53 |
| kanzure | strages: have you looked into skdb yet? | 11:54 |
| genehacker2 | I can write a little program that will calculate carbon equivalent which determines the feasibility of making something by welding | 11:54 |
| genehacker2 | I guess I could write up stuff for welding | 11:55 |
| kanzure | how does ":carbon equivalent" determine the feasibility of making something by welding? | 11:55 |
| genehacker2 | and deformation processing | 11:55 |
| genehacker2 | which is how 80% of all metal parts are made | 11:55 |
| genehacker2 | carbon equivalent determines if the materials being welded need to be preheated and/or postheated | 11:56 |
| genehacker2 | also welding material deposition rate calculation is hard | 11:56 |
| genehacker2 | as far as I know | 11:57 |
| genehacker2 | argh | 11:57 |
| genehacker2 | in/min | 11:57 |
| genehacker2 | I think I should start on casting first though | 11:59 |
| genehacker2 | also | 12:00 |
| genehacker2 | does maintenance go under consumables? | 12:01 |
| genehacker2 | for example, a forging machine will need material removed from the compressing plates periodically to insure that the tolerances are right | 12:02 |
| strages | kanzure: yeah. I know they're very similar | 12:03 |

| ybit2 | any45050298: i'm on my break right now, i was thinking about your problem, obvioulsy you have a serious saturation problem, but i can't recall the specs on the transformers, didnt' you tell me last night? | 12:53 |
| ybit2 | i'll have about 2 more hours to sit and think about it :P | 12:53 |
| any45050298 | some specs | 13:14 |
| any45050298 | been reading too | 13:15 |
| any45050298 | seems a lot of small motors, under 10hp (small??), exhibit such distortion when unloaded | 13:15 |
| any45050298 | some distort even when loaded | 13:16 |
| any45050298 | for unknown reasons, 3phase motors are worse, but care less | 13:16 |
| any45050298 | remembering what i have seen of the insides of motors, cheap 3phase motors have thinner iron on the circumference, so do very small singlephase motors | 13:17 |
| any45050298 | like the coils are inductances on electrons, i suspect the thinner iron is making "inductances" to the magnetic field, which feeds back/interacts with the other bits of the motor and the coils, and that makes a mess of the *voltage* when lightly loaded | 13:19 |
| any45050298 | if not the current when heavily loaded | 13:19 |
| any45050298 | where the displacement/slip of the rotor becomes dominant | 13:19 |
| any45050298 | however, the transformer iron shouldn't slip like a motor does | 13:19 |
| any45050298 | so iam still unsure, except http://designerthinking.com/transformers.html looks like the peak that forms when the transformer is loaded may be because the harmonic's sine-low-point is occuring at the 60hz fundamental's peak, and the load damps the harmonic | 13:21 |
| any45050298 | so the peak isn't opposed by that harmonic | 13:21 |
| any45050298 | BUT again, that load i used is resistive, it's not the voltage-clamping action that a battery charger would do | 13:21 |
| any45050298 | i need a <20v variable load good for 20amps :-/ | 13:29 |
| any45050298 | maybe on a 488 buss | 13:30 |

| ybit | kanzure: but there are plenty of how-tos on fixing the problem, here's a decent example: http://www2.electronicproducts.com/Conquering_inductive-load_demons-article-surr_phoenix_aug2007-html.aspx | 16:26 |

| ybit | "AFM is the most commonly employed approach for top-down nanomanipulation research, explains Gorman. However, AFM suffers from a number limitations, as the nanoparticles stick together during manipulation and cannot be lifted from the substrate. This means that nanodevices constructed using AFM may be aesthetically pleasing and provide insights into what might be achievable but it cannot build practical nano machines." | 20:12 |
| ybit | ""Our micro-scale nanoassembly system is designed for real-time imaging of the nanomanipulation procedures using a scanning electron microscope," explains Gorman, "and multiple nanoprobes can be used to grasp nanostructures in a cooperative manner to enable complex assembly operations."
