05:18 verak got one that is 2m
05:19 veverak and I have been curious if adding "connectors" won't harm it's abillity to read temperature
05:30 SpeedEvil With the right connectors - no.
05:30 SpeedEvil It depends what you mean by harm.
05:30 SpeedEvil And what you're reading.
05:30 SpeedEvil Connectors made of the wrong stuff tend to cause several C errors at most.
05:31 SpeedEvil In some apps, you may not care at all about this.
05:31 SpeedEvil Whate're you trying to measure
05:31 veverak 3d printer hot end
05:32 veverak http://reprapworld.com/?products_details&products_id/280/cPath/1616_1671
05:32 veverak http://www.ebay.com/itm/40Pcs-3-5mm-Golden-Plated-Bullet-Banana-Plug-Male-Female-Connector-fr-RC-Battery-/301585563003?pt=LH_DefaultDomain_0&hash=item4637e67d7b something like this but much smaller is what I wan t to use
05:32 veverak 1mm propably
05:37 SpeedEvil you want to measure a hot-end and you're needing >2m in a 3d printer?
05:37 SpeedEvil how big is this?
05:39 SpeedEvil In general, it's not going to be an issue, you may get a fraction of a C error. However, those are really not meant to join 0.2mm diameter non-solderable wire

05:40 SpeedEvil these have the pins made out of the right metals so there is no error.
05:41 SpeedEvil you need to use extension wire made for this
05:41 SpeedEvil thermocouple extension wire
12:44 rue_bed why not just put a board BY the thermocouple and take the resulting signal back
12:45 rue_bed be it digital or analog
12:45 rue_bed like, really.
12:45 rue_bed if yo uwan tto change ht sensor, you shouldn't have to unwind 2m of wire from a blooming harness
13:26 veverak I practically use 1.5m of the wire
13:26 verak got printer in the box, so electronics is outside o
13:27 veverak and chip that reads it is not external but on the base board
15:32 rue_shop3 see, should have made your own :)
21:11 reduce if i have 2 drones in relatively close proximity, is there a sensor that can determine their distance?
23:31 rue_shop2 you can use the motors if they get close enough
23:31 rue_shop2 look for sudden surges in torque
