--- Day changed Sat Jun 20 2009 00:02 < genehacker> well I was just thinking about automatically designing laser cutters the other day 00:03 < ybit> http://nathan.instras.com/projects/spin-coater/index.html :: spin coater for ~$70 00:05 < ybit> "Spin coater based on brushless dc motor of hard disk drivers" 00:07 < genehacker> google maskless lithography dlp projector 00:07 < genehacker> you will find what you need 00:07 < ybit> hmm can't ssh into serverftp to upload 00:08 < ybit> genehacker: what i need for?... 00:08 < genehacker> it show you how to make a simple spin coater using a blender 00:09 < genehacker> and also a machine for exposing photoresist 00:09 < ybit> We have developed a novel programmable, low cost, spin coater to be used for applications where flat substrates are coated with an uniform 00:09 < ybit> thin layer of a desirable material. The equipment is built with dc brushless motor present in most of the hard disk drivers (HDDs). The system 00:09 < ybit> offers manual control, wide speed range (from 0 to 10,000 rpm), spin speed stability and compact size. The paper also describes the use of such 00:09 < ybit> equipment for the fabrication of thin poly(o-methoxyaniline) (POMA) films, which are of particular interest for design organic electronic devices, 00:09 < ybit> such as diodes, transistor, sensors and displays. 00:09 < ybit> interesting 00:10 < ybit> genehacker: are you talking about your post on diybio? 00:10 < genehacker> it is related 00:12 < ybit> hough they had trouble achieving uniform illumination which 00:12 < ybit> means they had to adjust the brightness with an image overlay and 00:12 < ybit> ended up only being able to use only 95% of the image after the 00:12 < ybit> overlay was applied. 00:12 < ybit> that 95 needs to be 100.. 00:13 < ybit> for dna synthesis, you are correct, it's not a problem 00:14 < genehacker> http://www6.in.tum.de/Main/StudentProjectsFullBodyTracking 00:14 < genehacker> check this out 00:14 < genehacker> not related 00:25 -!- genehacker_ [n=chatzill@cpe-67-9-157-136.austin.res.rr.com] has joined #hplusroadmap 00:28 -!- kardan| [n=kardan@p54BE5BE1.dip.t-dialin.net] has joined #hplusroadmap 00:34 -!- xp_prg [n=xp_prg3@99.23.56.166] has quit ["This computer has gone to sleep"] 00:39 -!- genehacker [n=chatzill@cpe-70-113-200-244.austin.res.rr.com] has quit [Read error: 110 (Connection timed out)] 02:08 -!- elias` [n=c@unaffiliated/elias/x-342423] has quit [Read error: 110 (Connection timed out)] 03:44 -!- digitaltao [n=digitalt@cpe-72-179-5-147.austin.res.rr.com] has quit [Read error: 60 (Operation timed out)] 04:02 -!- digitaltao [n=digitalt@cpe-72-179-5-147.austin.res.rr.com] has joined #hplusroadmap 05:42 -!- digitaltao [n=digitalt@cpe-72-179-5-147.austin.res.rr.com] has quit [Read error: 110 (Connection timed out)] 05:42 -!- digitaltao [n=digitalt@cpe-72-179-5-147.austin.res.rr.com] has joined #hplusroadmap 07:23 -!- nsh [i=sbp@wikipedia/nsh] has quit [Read error: 104 (Connection reset by peer)] 07:38 -!- nsh [i=sbp@59.176.232.72.static.reverse.ltdomains.com] has joined #hplusroadmap 09:13 < kanzure> ybit: can you give me an index of the interesting papers that you have found in the last few days please?
