00:02 eadthem any alloys that would be easer to magnitise?
00:02 eadthem i know 300s are out
00:15 rue_school hahahah there is a dog trying to immitate the fire truck siren
00:18 rue_school it cant get the pitch of its voice up
00:31 blockh34d thats adorable
00:31 blockh34d <3 dogs
00:31 blockh34d one of my dogs likes to 'work'
00:32 blockh34d when i start working on something he'll go get some of the scraps of wood i leave around for him and he'll chew on them and kind of arrange them like he's trying to build someting
00:32 blockh34d the other day i found some of them stacked up on edge, he looked pretty proud of that
00:32 blockh34d and he loves to run around with a paintbrush in his mouth
00:33 blockh34d like he's going to go paint a fence or something... adorable
01:16 rue_school how effective couldn't it possibly be to paint a fence using your dogs love it carrying sticks
01:37 zhanx- 10%
14:06 mbrumlow Oh hey, there is a channel
14:07 mbrumlow people keep making it run into a wall
14:07 mbrumlow but

17:01 rue_school what you got square wheel on it or soemthing!?
17:01 rue_school whats doing the streaming?
17:01 rue_school its in north america, were the only ones stupid enough to use red edit signs
17:02 rue_school is the latency more or less than 5 seconds?
17:03 rue_school how does one unlock the speed controls?
17:08 Technicus Hello . . . what's going on over here?
17:09 rue_school were driving a robot in circles in an area with bad wifi
17:11 Technicus Have any of you ever read motor current sensor data from a roomba via an arduino?
17:11 Technicus I am having trouble doing that.
17:11 Technicus And I am looking for help.
17:15 mbrumlow Howdy!
17:16 deshipu yo
17:16 deshipu Technicus: no idea about that, but maybe if you describe your problem in more detail someone will have an idea
17:17 Technicus Here is the code I am trying: https://gist.github.com/Technicus/be8edc7430440139224f
17:18 Technicus Here is the documentation for the roomba: http://www.irobot.com/~/media/MainSite/PDFs/About/STEM/Create/create_2_Open_Interface_Spec.pdf
17:18 mbrumlow Did anybody here play with my bot? I posted a link earler.
17:19 deshipu Technicus: shouldn't you wait for data on the serial?
17:19 Technicus When I request motor current sens data from the roomba it is 255 255 and does not change. I do not think I am reading the data properly . . .
17:20 deshipu Technicus: are you sure it's not -1?
17:20 deshipu Technicus: try to assign it to a signed int, and then print it
17:20 Technicus I do not know what it is.
17:20 deshipu Technicus: not to a char
17:20 deshipu well, byte
17:21 Technicus deshipu: would this work: Serial.print((signed int)response[0]);
17:21 deshipu no
17:22 deshipu Serial.print(roombaSerial.read());
17:24 Technicus deshipu: it is 255
17:25 Technicus no it is -1
17:25 Technicus what does that mean?
17:25 deshipu see the docs on arduino.cc
17:26 deshipu https://www.arduino.cc/en/Serial/Read
17:36 Technicus deshipu: I updated to this: https://gist.github.com/Technicus/be8edc7430440139224f
17:36 Technicus but it only returns 0
17:37 deshipu I think you should wait for something to become available
17:45 Technicus deshipu: how could I do that?
17:46 deshipu keep on checking until Serial.available() is non-zero?
18:14 Technicus deshipu: like this: `while (roombaSerial.available() < 2) { }`?
18:15 deshipu Technicus: yeah, maybe with a delay inside
