04:55 AM Tom_L: morning
05:13 AM Tom_itx is now known as Tom_L
05:30 AM rue_bed: closer to where I should be
05:30 AM rue_bed: actually woke up about 2:30
05:31 AM rue_bed: want to play with lasers a bit and an led projection idea
05:31 AM rue_bed: if I can
06:34 AM rue_mohr: 2241 it jumped by a few
07:24 AM rue_shop2: oh yea, the projector

08:45 AM rue_mohr: so
08:46 AM rue_mohr: distraction/project chart so far this year
08:46 AM rue_mohr: but of a funny threshold for whats on it
08:46 AM rue_mohr: first step of microscope cover slips as beam split & splice
08:47 AM rue_mohr: then adding in a second beam
08:47 AM rue_mohr: I dont think the intensities are gonna work out
08:48 AM rue_mohr: and some messing around with doing some projection text
05:38 PM polprog: i wonder if i could reuse the revolving mirrot from a barcode reader with a regular galvo mirror to make a projector
05:39 PM polprog: use the revolving mirror for horizontal scan and the galvo for deflection
05:39 PM polprog: to make a scope
05:39 PM polprog: or use two revolving mirrors for raster scanning, if you can get one to rotate $lines times slower than the other
05:40 PM polprog: ive got a couple simple price scanners
05:40 PM polprog: motorola 68k, the kind that you install in a desk
05:40 PM polprog: i could reuse these
05:54 PM polprog: hmm they have 5 or 6 mirrors each
05:54 PM polprog: PAL line period is 64 us
05:55 PM polprog: 15.625kHz
05:55 PM polprog: /5 = 3125 r/s
05:56 PM polprog: *60 = 187k rpm
05:56 PM polprog: shit
05:56 PM polprog: not doable
05:56 PM polprog: i could do slow scan though, 16 or something lines, 30+ Hz refresh rate
05:57 PM polprog: that would be... [16*30/5]*60
05:57 PM polprog: 5760rpm
05:57 PM polprog: 16 30 * 5 / 60 *
05:58 PM polprog: I should make a calculator bot, but it will be RPM cause i dont know how to parse anything more advanced
05:58 PM polprog: i mean, i know but i cant be bothered to implement that
07:23 PM rue_mohr: the mirror my thing has is 8 sided
07:23 PM rue_mohr: I have the motor on slow and its 4.2Khz
07:23 PM Tom_L: octagon
07:54 PM rue_mohr: I need some code to be written
10:28 PM Tom_L: well hopefully you found the right guy for the job
