[07:45:49] <Connor> renesis: What is that ?
[07:48:47] <renesis> i named it feed block
[07:49:10] <Connor> What's it for or do ?
[07:49:21] <renesis> d batteries fall out of a tube into the fork, it shoves the battery forward, nexy battery sits on the delrin plate on top
[07:50:15] -!- anth0ny_ has quit [Quit: anth0ny_]
[07:50:20] <renesis> after battery is measured, feed block moves back, next battery falls into fork while some other actuators knock the battery left or right depending on voltage once feed block is out of the way
[07:50:49] <Connor> interesting.. fingers look bigger than a D battery..
[07:50:57] <Connor> guess I'll have to see it when complete.
[07:50:59] <renesis> delrin on top so the batteries slide nice, delrin on bottom so the feed block slides nice on machined aluminum platform
[07:51:07] <renesis> is class project thing
[07:51:29] <renesis> yeah its oversized, slightly bigger than the feed tube ID
[07:52:02] <renesis> should sell center a bit when pushed forward, and the measurement terminal will be wide enough shouldnt matter
[07:52:43] <renesis> the slot in between the top and bottom acrylic fork bits is for a optical interference sensor
[07:53:01] <renesis> just going to mount with some double sided sticky
[07:53:15] <renesis> some cheap vhb type stuff
[07:53:50] <renesis> hope it works
[07:54:12] <renesis> i stayed late in lab getting the retarded ladder logic for it working right
[07:54:42] <renesis> walk out at midnight, my custom 24" race bmx stolen
[07:54:50] <renesis> so if this shit doesnt work, im pissed

[19:08:13] -!- nofxx_ has quit [Ping timeout: 260 seconds]
[19:08:49] <CaptHindsight> or yeah you can run 4-1" chase nipples instead of one big 2"
[19:08:55] <CaptHindsight> whatever you want
[19:10:08] <CaptHindsight> the problem with a chase nipple is that it doesn't bite into the metal on the flared side of the nipple
[19:10:58] <CaptHindsight> so for electrical power installation they require a close nipple with nuts that bite into the box and then you have to add plastic bushings to each side of the nipple

[19:17:33] <zeeshan> i think i need to look at them closer

[19:49:13] <zeeshan> thats how many contacts i need to pass through

[20:06:51] <zeeshan> some pics of the connectors that came with the machine that i'd like to reuse if i can.

[20:08:41] <zeeshan> 5x5 = 25* 6 pin each

[20:09:53] <zeeshan> the other ones say 250/16

[20:10:36] <CaptHindsight> automotive wire to wire connectors like those are cheap
[20:11:24] <CaptHindsight> $2 connectors that end up $50 at the stealership

[20:11:56] <zeeshan> i have ton of those connectors for race car wiring
[20:12:01] <zeeshan> but theyre only rated for 24vdc max i think.
[20:12:09] <Tom_itx> thing i hate about auto connectors is every single one is different it seems
[20:12:22] <Tom_itx> and they all lock some how

[20:20:04] <zeeshan> did i not just say
[20:20:08] <zeeshan> i already have connectors that came with the machine
[20:20:09] <zeeshan> sigh
[20:20:35] <zeeshan> i dont understand the point of using automotive connectors when i already have some that came with the original controller?!?
[20:20:35] <CaptHindsight> zeeshan: jfc why are you even asking then?
[20:21:12] <zeeshan> i gues its my fault
[20:21:14] <zeeshan> i was not clear
[20:21:31] <zeeshan> i'm not sure how to mount em on the outside of my box.
[20:21:43] <zeeshan> i think im going to need a rectangular hole
[20:21:43] <CaptHindsight> my apologies if you've suffered a recent head injury
[20:22:13] <zeeshan> actually, i have,
[20:22:29] <zeeshan> thats why i have not been on irc much
[20:23:07] <CaptHindsight> understandable, been out with the flu myself
[20:23:28] <zeeshan> i possibly have a tumor in the middle ear

[20:24:02] <zeeshan> im hearing a constant ringing of my left ear and its driving me insane! :)
[20:24:38] <zeeshan> im really wondering if that 250/16 marking means 250v 16A
[20:24:54] <zeeshan> cause the original box had some 110V pins
[20:24:58] <zeeshan> going through the red connectors.

[20:32:24] <CaptHindsight> https://www.flickr.com/photos/128539016@N05/15358446183/ those contacts are enormous
[20:44:52] <zeeshan> youre right
[20:44:55] <zeeshan> i took them all apart now
[20:44:56] <zeeshan> theyre huge!
[20:45:03] <zeeshan> i dunno why i was thinking they were small
[20:45:16] <zeeshan> my only main concern now is this
[20:45:24] <zeeshan> glass scales analog signal comes to this connector.
[20:45:27] <Connor> But, they're not meant to be bulkhead
[20:45:42] <zeeshan> connor im just gonna silicone goop it up
[20:45:45] <zeeshan> around the rectangular hole
[20:45:54] <Connor> ok.
[20:46:28] <zeeshan> so glass scale analog signal comes to this connector (3 pairs of differential signals)
[20:46:42] <zeeshan> 5v signal.
[20:46:49] <zeeshan> will passing it through this connector cause issues? :/
[20:47:01] <zeeshan> especially if its right next to a 24vdc limit switch signal
[20:47:29] <zeeshan> the reason i ask is this:
[20:48:27] <zeeshan> the heidenhain glass scale wires are terminated using this connector:

[20:48:28] <zeeshan> top right
[20:48:39] <zeeshan> its a fancy schamncy connector..

[21:37:49] <zeeshan> okay guys i took apart one of the glass scale wire bundles
[21:38:10] <zeeshan> it has an external shield... which is supposed to get bonded to the housing of the connector
[21:38:24] <zeeshan> then theres a bundle of wires each with 2 pairs in it with its own internal shielding
[21:38:38] <zeeshan> own shielding i mean. the manual refers to this as "inside shield"
[21:38:44] -!- Camaban has quit [Quit: Leaving]
[21:38:54] <zeeshan> and it supposed to ground at the PCB of the interpolator
[21:39:00] <zeeshan> can someone explain this socery :)
[21:41:12] <CaptHindsight> earth ground/chassis ground and signal ground
[21:41:27] <zeeshan> the signal ground is floating relative to chassis ground?
[21:42:03] <CaptHindsight> inside shield is signal ground
[21:42:09] <zeeshan> CaptHindsight: whats the point of having a twisted pair and having its own shield
[21:42:12] <zeeshan> and then having 3 sets of these..
[21:42:24] <zeeshan> vs having 3 twisted pairs with one big shield?
[21:42:28] <CaptHindsight> poor differential amplifiers
[21:42:56] <CaptHindsight> in theory the differential signals cancel out common mode noise
[21:43:16] <zeeshan> i understand that :P
[21:43:34] <zeeshan> but i don't get the purpose of shielding each twisted pair vs shielding them all together with one shield?
[21:43:42] <zeeshan> *of them
[21:44:18] <CaptHindsight> this assumes perfect out puts and inputs
[21:44:19] <zeeshan> the only logical reason i can think of is to stop "cross-talk"
[21:44:31] <roycroft> you don't want crosstalk leaking over from one pair to another
[21:44:35] <roycroft> yes
[21:44:45] <CaptHindsight> so to make up for olden electronics they would add extra shields
[21:45:43] <CaptHindsight> thats why today you'll see 10gb over copper vs just 10mb
[21:45:51] <CaptHindsight> better amps
[21:46:41] <zeeshan> damn old electronics! :)
[21:46:56] <zeeshan> my next question is this.. and i really think im overthinking it, but someone will prolly have a better understanding
[21:46:57] <CaptHindsight> they used what they had
[21:47:04] <CaptHindsight> in the best way they could
[21:48:26] <CaptHindsight> and even though the electronics are much better today the cheapskates running manufacturing just cut corners and the products end up performing nearly as poorly
[21:48:32] <zeeshan> wire with 4 twisted pairs each with its own internal shield + the entire cable with external shield -> bulkhead connector (the one i posted before) the external shield would go to one pin, the internal shield to another pin, each twisted pair obviously to its own pin. -> out of bulkhead the external shield pin connects to external shield, and internal shield for each twisted pair connectrs to the
[21:48:43] <zeeshan> internal shield pin
[21:48:57] <zeeshan> so technically at 4-5 mm of the connector, there will be unshielded stuff? :/
[21:49:19] <zeeshan> this is why heidenhain uses a round connector with the internal shield pin being the very middle pin
[21:49:30] <zeeshan> and the body of the bulkhead connector being the external shield
[21:49:33] <zeeshan> so there is no break in the shield
[21:49:43] <zeeshan> does that make sense?

[22:32:32] <LeelooMinai> MEMs is best what you get now

[23:02:03] <CaptHindsight> zeeshan: those are only silicone
[23:03:03] <CaptHindsight> if you want to fabricate nano machines then you use 2-photon lithography, or interference lithography

[23:32:22] <zeeshan> wolw
[23:32:24] <zeeshan> thats cool1!
[23:39:30] <CaptHindsight> zeeshan: it's still odd that there are lots of practical parts that can already be printed this way but the examples in the press are similar to Yoda heads
[23:46:26] <zeeshan> they need to put a lot of funding into this
[23:46:30] <zeeshan> it could cure cancer.
[23:46:44] <zeeshan> especially if you could put a sensory system on it to detect bad cells.
[23:48:17] <SpeedEvil> Well - no.
[23:48:26] <SpeedEvil> Single cogs and isolated gears do fuck all
[23:48:49] <SpeedEvil> Mature nanotech - programmable tiny bots are some way off yet.
[23:49:02] <SpeedEvil> For a large number of reasons
