01:20 AM rue_house: its not muscle wire
01:23 AM rue_house: large cables, ont ehw rong side of the fingers
01:23 AM rue_house: flex sensor
01:23 AM rue_house: 14 channel !?!?!
01:23 AM rue_house: oh this is the palm photo
01:23 AM rue_house: butit ... cupped backwards?
01:24 AM rue_house: plastic stitched to ... well leather anyhow, ... interesting
01:26 AM rue_house: dont quite get what the orange and yellow are taking power to
01:32 AM gottaname|wurk: rue_house, multimeter time nao'
01:50 AM rue_house: http://www.electronics-lab.com/wp-content/uploads/2015/03/schematic40.png
01:50 AM rue_house: oh, hehe
01:51 AM rue_house: I was giving it DC input...heh
01:52 AM rue_house: I'll try that again later
01:56 AM Anniepoo_: ttm, anniepoo in all lower doesn't need single quotes
02:07 AM Anniepoo_: sorry ww
04:16 AM pokmo: is it a good idea to mesh a 5mm thick 16T plastic gear with a 1.5mm thick 42T plastic gear?
04:16 AM pokmo: does the difference in thickness matter?
04:27 AM deshipu: it affects strength, friction and wear
04:37 AM pokmo: deshipu, but would it be worse than meshing 1.5mm with 1.5mm though?
04:47 AM deshipu: no, but you waste material
04:50 AM pokmo: right
06:46 AM z64555: the kids at the competition where using sewing machines for something
06:47 AM z64555: maybe for the bumpers they were using
06:55 AM * z64555 reads up on cell phone antennas
07:04 AM z64555: doh, can't believe I forgot about shortwave radio
07:34 AM robotustra: rue_house: it's a data glove
07:34 AM robotustra: 15 DOF + 9DOF IMU
08:08 AM z64555: no thumb?
08:09 AM robotustra: whut?
08:10 AM z64555: The thumb's root is a ball joint, so you're missing a DoF
08:10 AM z64555: although tenchically each of the phallanges have 4DoF
08:11 AM robotustra: no
08:11 AM robotustra: I don't miss any DOF
08:11 AM z64555: ...no what?
08:11 AM robotustra: I use only 3 of them
08:11 AM robotustra: I don't need more
08:12 AM z64555: ok, I'm confused again, lol
08:12 AM z64555: might help if I could look at the pics/video
08:13 AM z64555: but I'm using my bandwidth for something else at the moment
08:14 AM robotustra: https://drive.google.com/open?id=0B6W33DRMzKC4T3Utak1JS0wySk0
08:23 AM z64555: agricraft, i c u
08:23 AM z64555: oh, which version of MC is this for, I didn't catch that when I started the download
08:24 AM z64555: and this is totally the wrong channel
08:27 AM z64555: the woes have having multiple IM clients open, each with multiple channels
09:15 AM rue_house: robotustra, wouldn't you be annoyed if I said that a data glove dosn't need to be able to actaully move?
09:15 AM rue_house: awe, I was looking forward to that video
09:15 AM cnnx: good morning
09:31 AM robotustra: rue_house: didn't got what you mean
09:31 AM rue_house: video isn't avilable
09:33 AM robotustra: I shared it, try again
09:34 AM rue_house: my version of chrome is like 6 months old, dosn't work on anything anymore
09:35 AM robotustra: so it's not a problem of link as you understand
09:35 AM robotustra: I'll not put it on youtube
09:35 AM rue_house: need a machine that updates chrome every day so I can view websites arbitrarily
09:39 AM rue_house: need to be there at 9... maybe a half hour drive....
09:39 AM rue_house: so 8:30 should be fine
10:49 AM rue_house: its nice of friends to wait for you
10:49 AM rue_house: its not nice when they decide to wait in orbit
03:40 PM Doe: can anyone recommend me a relay that can do 5 to 12v, 2A - on/off
03:56 PM robotustra: do in the coil or commutate 5-12 V?
03:58 PM Doe: robotustra: I've a motor that is speced at 6v-12v -I'm planning to run it at 5v or 12v depending on what I have available
03:58 PM Doe: I want to just switch it on/off
03:58 PM Doe: https://www.aliexpress.com/item/12V-Single-1-Channel-Relay-Driver-Module-Photoelectric-Isolation-Input-NPN-PNP-SV-5A1R1P-N/32796905048.html - Can I use this for 5V on/off ?
03:59 PM Doe: robotustra: dc brushed
04:00 PM robotustra: it looks like it should work
04:01 PM robotustra: but not sure about 5V
04:02 PM robotustra: but gate voltage is 3.3V
04:02 PM robotustra: why do you need galvanic isolation?
04:02 PM robotustra: you can use usual driver for DC motor
04:03 PM robotustra: like A4988
04:03 PM Doe: I'm not sure about relays, and if they work with different voltages. I would also like to make it work on 9v
04:03 PM Doe: https://www.aliexpress.com/item/1-8V-3V-5V-12V-PWM-DC-Motor-Speed-Controller-ultra-small-LED-Light-Modulator-Electronic/32669024702.html - I was thinking of using these motor controllers
04:05 PM robotustra: sorry DRV8833
04:05 PM robotustra: http://www.robotshop.com/en/pololu-dc-motor-driver-3a-5v-28v-mc33926.html
04:05 PM robotustra: this one
04:06 PM robotustra: Doe: do you need manual control?
04:08 PM Doe: robotustra: I just wanted the be able to shut down things when needed
04:10 PM Guest71278 is now known as dO_ob
04:51 PM cnnx: maybe it don't exist :(
04:51 PM cnnx: i can't find a motor in stock for my specs
04:51 PM cnnx: and i need 4
04:51 PM cnnx: ~188rpm/min ~543 ozf-in 12vdc
05:12 PM codepython777: /join #multicopters
09:11 PM cnnx: what do you guys think of this
09:11 PM cnnx: https://www.piborg.org/diddyborg
09:16 PM zhanx: crazy expensive
10:11 PM cnnx: zhanx: if you buy the pieces yourself its more
10:11 PM cnnx: and it wont look as good
10:40 PM zhanx: cnnx: yea no
10:51 PM Snert: pololou has a neat little tracked rover too.
