45:29 <K> hey rusty, that japanese bolt-lenghtener thing - actually useful.
46:19 <rust_collector> bolt stretcher?
52:54 <K> cutter
53:15 <K> needed a bunch of 7mm M3
53:27 <rust_collector> well, yeah
53:53 <K> and they say impulse purchases never work out
53:55 <K> ha!
54:16 <rust_collector> who?
54:23 <K> thems!
54:27 <K> u know
54:51 <K> ppl who write comments in youtube videos
57:02 <rust_collector> them, in youtube comments, either means enyone different, or jews, depending on if their lack of hair is natural or chosen

59:02 <rust_collector> this, otoh, is just as horrible as I would imagine it would be
59:37 <K> yes, points to rust_collector
00:14 <rust_collector> i feel pointy now
30:28 <arch> rust_collector, lol
30:41 <arch> > them, in youtube comments, either means enyone different, or jews, depending on if their lack of hair is natural or chosen
31:29 <arch> what if they wanted to be polite and refer to transgender folks in a non-gender specific way
32:34 <rust_collector> well, those who cut the hair off, had to stop using the ((( thing, because the ultra geeks who do stuff in lisp...well, they sent some kind of message
33:58 <rust_collector> well, if they want to be polite... I dunno.
41:32 <Ysjoelfir> pff.... being polite... who needs that anyways?
06:33 <arch> hey! fuck you... and i'll see you tomorrow

59:31 <MrMobodies> Hello
59:37 <MrMobodies> Feeling absolutely miserable
59:45 <MrMobodies> I believe it is the cold
59:52 <MrMobodies> the headache is gone
00:38 <MrMobodies> there is nothing bad enough to feel this miserable about.
01:11 <MrMobodies> I am hoping to get better from tomorrow
01:47 <MrMobodies> went to the local pub earlier, which opens from Wednesday to Sunday and had to come back quick to go to toilet due to the cold
02:03 <MrMobodies> well a poor stomach

01:25 <MrMobodies> put in a psu without -5v and the ISA sound card seems unaffected.
02:36 <MrMobodies> yep, even the onboard sound connected to the mixer causes the noise on the isa
02:45 <MrMobodies> looks like i can't plug anything else in
03:41 <MrMobodies> last one to try is the usb sound cards then I'll decide whether or not to return the motheroard
26:58 <arch> how much does it hurt chips when they operate at 160C? for example i've seen many switching ICs have an overtemperature shutdown around 160C and hysteresis of maybe 20C, so they'll start back up at 140C.
27:35 <arch> i've managed to do it for a few sot-23-6 buck regs myself, when they were placed in an extremely tiny pcb area
47:32 <electrohead> I heard it makes the electrons scream

13:09 <Halcyon> What's an easy way to discharge coin cells for disposal? Reckon just short them out for a bit?
13:17 <Halcyon> They are old and a little bit crusty
13:52 <MrMobodies> 150GB for a game? Wow, that's a new one.
14:09 <MrMobodies> what game is it?
14:32 <Halcyon> Oh actually disregard. Apparently the bins at the supermarket take them
15:06 <MrMobodies> oh yes, they have those here as well at supermarkets
15:36 <Halcyon> Wasn't sure if they took small cells, but they do.
15:54 <Halcyon> Usually I've dropped off Lipo packs in there
16:06 <MrMobodies> I rememember at the recycling center a few years ago they built this new section just for lithium batteries incase they catch fire
16:52 <MrMobodies> I have a few swollens ones under a pot in the garden which is due to be taken there
17:29 <Halcyon> I'm still surprised they have those disposal bins inside the stores. Granted they are at the entrance or near a window, but still.
19:14 <MrMobodies> Halycon, do you use Pfsense?
19:51 <Halcyon> I do indeed
20:29 <MrMobodies> I am looking for a solution, if it could be done with pfsense
21:11 <MrMobodies> https://i.postimg.cc/R97SpBG2/keene-IR-IP-routing.jpg
22:11 <MrMobodies> Keene IR plugin (4 of them) points to virtual IP on pfsense which gets forwarded to the Keene Matrix but it must look like it comes from the source address (set in the Keene Ir plugin)
22:25 <MrMobodies> ooops 4 virtual IP's I mean
24:48 <MrMobodies> https://i.postimg.cc/WpbH7gXf/Keene-IRpluin.jpg
25:38 <MrMobodies> I could copy all the IR codes and use the tool to insert what output but that't be a lot of work
26:46 <Halcyon> It is a multicast thing on a network segment?
26:48 <MrMobodies> but if I can set the IP addresses on the unit, associate them to what IR output, set them up on KeeneIR then use Pfsense to pass it through and make it look like it is coming
27:03 <MrMobodies> from a certain ip
27:27 <Halcyon> So it listens for commands from a source, and re-broadcasts them over a network?
28:42 <MrMobodies> I see
28:52 <Halcyon> It's not very clear to me how that works. I thought they were port numbers, but apparently not
29:20 <Halcyon> Those source addresses seem to be more of a blacklist, more than anything
29:33 <Halcyon> So by default, anything can control everything.
32:34 <MrMobodies> I am sorry I don't think I explained well enought what I am trying to do
32:34 <Halcyon> What's the network setup like? Is everything on a single subnet, or is there a dedicated network or VLAN for IR controllers?
32:38 <MrMobodies> aaah
32:46 <MrMobodies> yes there are many
32:56 <Halcyon> Many networks or hosts?
32:59 <MrMobodies> in fact 'll get the map which might help for this thing i want to do
33:00 <MrMobodies> yes
33:05 <electrohead> !coffee Halcyon
33:05 <Halcyon> Hahah OK
33:05 * EEVBot slides a cup of joe to Halcyon
33:08 <Halcyon> Heyyyy electrohead
33:11 <electrohead> \o/
33:12 <EEVBot> I
33:12 <EEVBot> { {
35:48 <MrMobodies> https://i.postimg.cc/kq552HFQ/Lan.jpg
37:01 <MrMobodies> https://i.postimg.cc/HYHYdvkQ/PFsense.jpg
37:01 <MrMobodies> I thought it might help
37:51 <MrMobodies> The KeeneIR is a network infrared transmitter and receiver
38:07 <MrMobodies> the Matrix unit has 4 IR inputs and outputs
38:24 <Halcyon> Holy fuck
38:25 <MrMobodies> I could set what IP address goes to what IR port
38:40 <MrMobodies> I could use 4 virtual machines with 4 ip's
39:04 <MrMobodies> https://i.postimg.cc/wgt7WPyD/IRrouting.jpg
39:22 <Halcyon> So my question is, is the Matrix and the IR transmitter that it will be addressing, all on the same network?
39:28 <MrMobodies> 192.168.11.11 Outputs 0001
39:33 <MrMobodies> 192.168.11.12 Outputs 0010
39:42 <MrMobodies> 192.168.11.13 Outputs 0100
39:49 <MrMobodies> 192.168.11.14 Outputs 1000
39:54 <MrMobodies> oh yes
40:05 <MrMobodies> yes it has a network port
40:05 <Halcyon> That really annoys me that you didn't do it the other way around :P
40:14 <Halcyon> .11 outputs bank 1
40:21 <Halcyon> .12 output bank 2 etc...
40:28 <MrMobodies> yes
41:40 <Halcyon> Anyway, I digress. So as long as you configure the matrix like you have above, then you can independently control 4 banks of IR TX. I don't see why you would need to make any changes on pfsense, if they are all already on the 192.168.11.0/24 segment
41:57 <MrMobodies> I need to make it look like the packets are coming from the source address above to take advantage of it's IR routing
42:16 <MrMobodies> using one Eventghost and many plugins with the above ip addresses
42:31 <MrMobodies> now this is where I think Pfsense might help,
42:54 <Halcyon> Do the transmitters not just listen for all commands on the network and wait for the one addressed to them? Do you need to manually specify the source address to listen to?
43:10 <MrMobodies> using a virtual IP, 192.168.11.11 in way that when it is sent, the Keene IR see's that as the source, not the wan address on the lan
43:21 <MrMobodies> oooh
43:41 <MrMobodies> this I use to send out IR codes to control disco lights
43:44 <Halcyon> It seems odd you would need to define IPs on BOTH ends, seems wasteful
44:46 <MrMobodies> it's also wasteful if I had to copy 20 to 30 buttons a remote, in the Keeene IR tool to define it and make another folder for a particiular ir output
45:16 <MrMobodies> or create 4 virtual machines wth the source IP
45:32 <Halcyon> Perhaps I'm not really wrapping my head around this gear properly, so not sure how much I can help. I imagined it to be almost like a DMX set up with addressing, but over IP
45:49 <MrMobodies> oh yes, it does involve that but not for the Keene IR thing
46:05 <MrMobodies> so
46:27 <MrMobodies> what that does, that network Ir routing table
46:43 <MrMobodies> https://i.postimg.cc/brmxrZKR/image.png
47:23 <Halcyon> I understand that bit, I think, the matrix is addressing banks of up to 4 transmitter modules?
47:30 <MrMobodies> Lets say I have 4 computers with Eventghost (all with different remote control IR codes via the built in webserver)
47:33 <MrMobodies> oh nonooon
47:45 <MrMobodies> it has individual 4 outputs
47:54 <MrMobodies> oh sorry addressable outputs
48:10 <MrMobodies> so I can send a an IR code from a button a webpage to say PORT 3
48:17 <MrMobodies> and it'd go to an IR dongle
48:49 <Halcyon> Right, so the source address on the matrix, relates to a PC controller of some sort?
49:10 <MrMobodies> yes
49:13 <MrMobodies> that's it
49:19 <Halcyon> So PC > Matrix > IR Transmitters ?
49:20 <MrMobodies> I got a picture of the unit
49:29 <MrMobodies> yes
49:47 <Halcyon> Right, now I understand
50:08 <Halcyon> Again, the question is, if everything is on the same subnet, why wouldn't that work?
51:00 <Halcyon> And to blacklist everything else you would set source address 0.0.0.0 to outputs 0000
53:39 <steve30> o/
53:39 <Halcyon> Hey Steve
53:39 <Halcyon> I had a Rolo last night

36:32 <MrMobodies> Computer IP 192.168.11.2... webpage button pressed -> Keene IR plugin #1 to go out of - > 192.168.11.11 -> VIP pfsense -> forwarded to Keene Matrix 192.168.11.3 (sees source address as 192.168.11.11) then tramsits ir code on port 1
37:00 <MrMobodies> Computer IP 192.168.11.2... webpage button pressed -> Keene IR plugin #2 to go out of - > 192.168.11.12 -> VIP pfsense -> forwarded to Keene Matrix 192.168.11.3 (sees source address as 192.168.11.12) then tramsits ir code on port 2
37:15 <MrMobodies> Computer IP 192.168.11.2... webpage button pressed -> Keene IR plugin #1 to go out of - > 192.168.11.13 -> VIP pfsense -> forwarded to Keene Matrix 192.168.11.3 (sees source address as 192.168.11.13) then tramsits ir code on port 3
37:19 <MrMobodies> and so o
37:44 <MrMobodies> sorry about all of this
41:28 <MrMobodies> For example if ony I could set 192.168.11.11 TO 192.168.11.14 on computer 192.168.11.2. Bind Eventghost to those IP'S and specify in the Keene IR plugin what IP within 11 - 14 it should leave to get sent to the Keene IR matrix
41:59 <Halcyon> But what differentiates the different buttons? Like is it by port number? Is there a command that's sent?
42:32 <Halcyon> Or it is just IR on/off, nothing more.
43:05 <MrMobodies> nonno nothing like that
43:11 <MrMobodies> Eventghost ha sa built in webserver
43:29 <MrMobodies> I capture the IR code with the Keen matrix plugin it has a receiver)
43:45 <MrMobodies> on event it triggers an action
43:54 <MrMobodies> I'll get the picture of what it is doing
53:22 <MrMobodies> here
53:23 <MrMobodies> https://i.postimg.cc/3Y8r0q7Q/Eventghost-wth-Keene-Ir-Plugins.jpg
53:41 <MrMobodies> this is how it works with one Keene IR plugin
54:36 <MrMobodies> press no2 on that remote, URL event appears, and for that one I select Keene IR plugin 2 and goes out of that unit. That's for the single Keene Ir's I have
57:47 <Halcyon> Yeah I'm not too sure. I'm sure I could figure it out if I was there, but without seeing the gear, how it works etc... it's just hard to come up with a solution
00:18 <MrMobodies> sorry about that
00:27 <MrMobodies> thanks for your help
00:43 <MrMobodies> it's would a miracle at this moment to get that working in a way
01:56 <MrMobodies> I have 3 Keene IR transmitters (SINGLE transmitter), and one matrix (FOUR addressable transmitters)
02:47 <MrMobodies> you can send an IR code intended for certain outputs between 1 to 4 (BY IP ADDRESS SOURCE)
03:49 <MrMobodies> so it'd USE (the source address) to determine WHICH IR port (out of the four) to send the IR code
03:56 <MrMobodies> or by machine
04:01 <MrMobodies> see the limitation?
08:05 <MrMobodies> so if I set the Keene Ir plugin to send it some virtual IP address on Pfsense (instead of the Keene IR unit) and then pfsense forwards) to the Matrix unit on some address I list in this table
08:06 <MrMobodies> https://i.postimg.cc/R97SpBG2/keene-IR-IP-routing.jpg
08:12 <MrMobodies> Say source address 2
08:31 <MrMobodies> and set the output for output 0100
11:11 <MrMobodies> 8 computer IP addresses can be specified and linked to any of the four outputs.
12:02 <MrMobodies> but what if I want to set the outputs and address them from one computer with one IP address
12:15 <MrMobodies> that's the problem I was trying to word
