01:53 thranduin anybody here worked with FRC before?
01:53 thranduin any advice to a rookie on a rookie team?
01:54 Triffid_Hunter FIRST robotics competition?
01:54 Triffid_Hunter bah
01:56 okminz test
02:07 home I hate when people leave XD
02:07 home I do FRC XD
02:07 home big waste of time, tbh
02:10 rue_mohr I think it gets a lot of epple into it
02:24 rue_mohr eeek, I forgot to go to bed...
02:24 rue_mohr !time
02:24 tobbor My watch says its 12:14AM Mon Dec 17 2012
02:24 rue_mohr yes, tommorow will suck
02:25 rue_mohr gnight internet
16:42 sku11knight hey guys, anybody played around with LIDAR much?
16:43 anannie sku11knight: I've tried ultrasound and Sharp's distance sensors
16:44 sku11knight trying to find out the main differences between http://www.robotshop.com/hokuyo-urg-04lx-ug01-scanning-laser-rangefinder.html?utm_source=google&utm_medium=base&utm_campaign=jos and http://www.robotshop.com/hokuyo-urg-04lx-laser-rangefinder-1.html besides the fact that the first one is half the price of the other one.
16:46 ace4016 the cheaper one actually looks better
16:47 ace4016 also, jeebus...
16:47 ace4016 that's pricey
16:48 sku11knight yeah, LIDAR's aren't cheap.
17:05 ace4016 you can afford that? :P
17:05 Triffid_Hunter ace4016: they've dropped, last time I looked at hokuyo 04LX it was >$2.5k
17:05 Triffid_Hunter had the pleasure of using one in a research lab
17:05 ace4016 hehe
17:06 Triffid_Hunter gives 1024 readings of 30cm-4m with 1mm precision up to 10 times per second
17:06 Triffid_Hunter has both serial and usb
17:06 ace4016 seems like doing anything interesting will cost lots of money
17:06 ace4016 sensor wise
17:07 Triffid_Hunter kinect is cheap enough to be very interesting, if you have enough cpu onboard to crunch the data
17:07 ace4016 aye
17:11 home Triffid_Hunter: I got a Kinect
17:11 home Triffid_Hunter: but even with a quadcore, it is intense..using the rGB camera
17:11 home the infrared camera is better..for low processing tasks I would guess :/
18:13 TELunus Don't you need both cameras on the Kinect for a 3d map though?
18:19 home well
18:19 home What if I didn't have the processing power for the 3D map?
18:20 home I would use the Kinect's other function.. :/
18:21 TELunus Ya.
18:21 TELunus It's just not as comparible to a LIDAR without the 3D map.
19:25 home guys uhm
19:25 home uhm yeah
20:37 Casper compressor hack done
20:52 home Casper: how..and cool :D
20:52 Casper http://youtu.be/13ZFGtNmsUg
20:53 Casper I only need 1 thing now: intake air filter
22:47 hackman127 Casper: Nice!
