| Kilos | morning all, ill be scarce at times , lotsa outside work | 07:44 |
|---|---|---|
| Symmetria | heh 4 hours.... | 07:47 |
| Symmetria | well, 4 hours and 13 minutes | 07:47 |
| Symmetria | till I'm standing at the altar and saying I do | 07:47 |
| inetpro | good mornings | 08:18 |
| inetpro | Symmetria: best wishes for a long and happy marriage! | 08:22 |
| Symmetria | thanks :) | 08:23 |
| inetpro | and don't forget to come back here from time to time afterwards :-) | 08:24 |
| inetpro | you've been way too scarce lately | 08:25 |
| Symmetria | lol busy is all :) | 08:25 |
| inetpro | np sir, enjoy the wedding day | 08:26 |
| * inetpro looking at Dodge power cuts with solar-powered internet http://www.fin24.com/Tech/Gadgets/Dodge-power-cuts-with-solar-powered-internet-20150220 | 08:28 | |
| inetpro | just the solution that I need | 08:29 |
| inetpro | now to work out how I can get all that one step at a time | 08:30 |
| inetpro | looks like I could start without the solar panel and inverter | 08:35 |
| Cryterion | inetpro the charge controllers are not very expensive, the panels however add up as you'll want a few up them | 08:55 |
| Cryterion | then use a car battery, the new type's around 80-100AH rather than a normal 7AH | 08:55 |
| Cryterion | And you'll need the inverter btw, true sine wave inverters are pricey, but the modified sine are fine for electronic equipment, just DON'T connect your fluorescent kitchen light to it | 08:57 |
| Cryterion | had one start it's own braai once (not it the appropriate place) | 08:58 |
| inetpro | :-) | 08:58 |
| inetpro | car batteries are expensive man | 08:58 |
| inetpro | and not made to last for 4 hours | 08:59 |
| inetpro | without getting charged | 08:59 |
| inetpro | need a deep cycle battery | 09:00 |
| Cryterion | deep cycle was the type I was looking for, most of the new car batteries are deep cycle | 09:01 |
| Cryterion | most new cars run at 15V now, and you must not let a deep cycle battery drop below about 10V otherwise you damage it | 09:02 |
| Cryterion | I have an 80AH connected directly to the 12V Sealed battery in a std UPS, allows a lot more on time than the 15mins at 650w from just the 7AH batt | 09:04 |
| mazal | Morning everyone | 09:13 |
| inetpro | Cryterion: at what cost? | 09:19 |
| Cryterion | I know it adds up! That's the unfortunate part :( | 09:36 |
| Kilos | sjoe | 09:49 |
| Kilos | everything is one step at a time | 09:50 |
| inetpro | ai! | 12:42 |
| inetpro | looks like costs have escalated massively as well | 12:43 |
| inetpro | at a battery centre outlet I can get a sealed 18AH lead acid battery for R645 | 12:44 |
| stickyboy | Man, Mac OS X font rendering is absolutely beautiful. | 12:45 |
| inetpro | hmm... | 12:45 |
| stickyboy | \o/ | 12:45 |
| inetpro | same story, more details: http://www.htxt.co.za/2015/02/10/beat-loadshedding-on-a-budget-take-your-tech-solar-for-r1-271/ | 13:40 |
| Kilos | hmm... | 16:25 |
| * Kilos wonders who sharky1 could be | 16:26 | |
| Kilos | hi kulelu88 | 16:26 |
| Kilos | we waiting for you lug peeps | 16:26 |
| kulelu88 | hello Kilos | 16:27 |
| kulelu88 | why you waiting? | 16:27 |
| Kilos | have you not heard of our latest venture? | 16:28 |
| kulelu88 | nope | 16:29 |
| Kilos | whew i cant find it now, but read last blog so long | 16:30 |
| Kilos | Maaz kilos.newblog | 16:30 |
| Maaz | http://kilosubuntu.blogspot.com | 16:30 |
| Kilos | i think i put a link there to ubuntutu africanteams | 16:30 |
| Kilos | bit busy now , will check just now | 16:31 |
| kulelu88 | nice beard oom | 16:35 |
| Kilos | hahaha | 16:35 |
| Kilos | my daughter had to trim it in the photo | 16:35 |
| Kilos | and hair | 16:35 |
| Kilos | she calls it my einstein hair | 16:35 |
| Kilos | https://wiki.ubuntu.com/AfricanTeams | 16:36 |
| Kilos | see we made place for lugs | 16:36 |
| Kilos | only i only know you inna lug | 16:37 |
| kulelu88 | I'm not part of the lug | 16:38 |
| Kilos | aw | 16:38 |
| Kilos | you know some of them dont you | 16:38 |
| kulelu88 | yeah. Just check meetup.com for the jozilug | 16:39 |
| Kilos | im bang to just join and ask them, lug peeps get offended easy | 16:43 |
| Kilos | they normally serious peeps | 16:45 |
| kulelu88 | they will get offended because it is ubuntu promo | 16:45 |
| kulelu88 | aren't you on the mailing list? | 16:45 |
| Kilos | see what i mean | 16:46 |
| Kilos | im on many mailing lists | 16:46 |
| kulelu88 | start the discussion in the mailing list then. | 16:46 |
| Kilos | i dont know if you can join thier list without first joining the lug | 16:47 |
| Kilos | their | 16:48 |
| Kilos | i go eat | 16:48 |
| Kilos | ohi superfly | 17:36 |
| Kilos | hi Cryterion | 17:37 |
| Kilos | oh my mazal on a saterday | 17:37 |
| Kilos | hmm... gonna rain | 17:37 |
| superfly | hi Kilos | 17:53 |
| inetpro | good evening | 17:54 |
| Kilos | hi inetpro | 17:54 |
| inetpro | Kilos: eh,... what you been up to today? | 17:55 |
| Kilos | i looked at you last link | 17:55 |
| Kilos | slept lots | 17:55 |
| Kilos | chatted debs some | 17:55 |
| * inetpro likes the last link | 17:55 | |
| Kilos | firefighting seems to have worn me out like never before | 17:55 |
| Kilos | i supposed dragging and breaking logs didnt help | 17:56 |
| inetpro | we need to track down that BushPower place in Midrand | 17:56 |
| inetpro | or find someone else who provide the 7.2Ah Lead Crystal Batteries at a reasobale price | 17:57 |
| Kilos | thats the trick | 17:57 |
| inetpro | I think 7.2 Ah will be good eneough for two hours | 17:58 |
| inetpro | enough as well | 17:58 |
| Kilos | but the bigger one would be better | 17:58 |
| Kilos | 18 better | 17:58 |
| inetpro | bigger is too expensive | 17:58 |
| inetpro | and won't last as long | 17:58 |
| Kilos | thats the prob always | 17:58 |
| Kilos | why | 17:58 |
| inetpro | Lead Crystal has a longer lifetime | 17:59 |
| Kilos | dont hey make large ones | 17:59 |
| kulelu88 | does anybody use this: http://subuser.org ?? | 17:59 |
| Kilos | or a couple in parralel should help | 17:59 |
| inetpro | Kilos: see http://www.bettabatteries.com/ and click on performance | 18:00 |
| inetpro | kulelu88: first time I see anything about subuser | 18:02 |
| Kilos | yip thats a good battery inetpro | 18:03 |
| inetpro | Kilos: BushPower has a 70Ah one at R2700 | 18:04 |
| Kilos | thta would be ideal but sjoe lotta bucks | 18:05 |
| kulelu88 | are these inverters? I could use 1 for my modem | 18:05 |
| Kilos | batteries | 18:05 |
| Kilos | http://www.htxt.co.za/2015/02/10/beat-loadshedding-on-a-budget-take-your-tech-solar-for-r1-271/ | 18:05 |
| Kilos | for that kinda setup | 18:05 |
| kulelu88 | solar won't help when loadshedding happens in the evening | 18:06 |
| Kilos | thats what the battery is for | 18:07 |
| inetpro | Kilos: but I think the 70Ah would immadiately also require a better/different more expensive charge controller | 18:07 |
| Kilos | why | 18:08 |
| inetpro | requires a charging voltage of between 14.4V & 14.8V during the bulk charging phase | 18:09 |
| Kilos | i dont know charge controllers at all, dont they just decide when and how hard to chrge a battery | 18:09 |
| Kilos | its still a 12v battery right | 18:09 |
| inetpro | yep | 18:11 |
| Kilos | its all about money, one buys the best one can afford | 18:11 |
| Kilos | 12v battery charger should work on any 12v battery | 18:12 |
| Kilos | that one for the incubator can be used when power on | 18:12 |
| Kilos | to bosst its voltage just put a cap across the outputs | 18:12 |
| Kilos | that will push it to 15v | 18:13 |
| Kilos | iirc | 18:13 |
| inetpro | yikes! | 18:13 |
| Kilos | what | 18:13 |
| inetpro | a cap across the outputs? | 18:13 |
| Kilos | then you can wait to get a solar panel | 18:13 |
| inetpro | never heard of that | 18:14 |
| Kilos | capacitor | 18:14 |
| Kilos | smooths and increases the voltage | 18:14 |
| Kilos | i didnt have one handy at the time i think | 18:14 |
| kulelu88 | mehh, why risk electronics worth so much with a make-shift voltage-adjuster | 18:15 |
| Kilos | can you read the output voltage then ill maybe remember more | 18:15 |
| Kilos | you are just charging a battery kulelu88 | 18:15 |
| inetpro | output voltage of? | 18:15 |
| Kilos | nothing to do with the equipment | 18:15 |
| Kilos | of the charger | 18:15 |
| Kilos | sigh | 18:16 |
| Kilos | there where the incubator plugs go in | 18:16 |
| Kilos | or were they clamps | 18:16 |
| inetpro | ah, I'll have to go look for that | 18:17 |
| Kilos | lol | 18:17 |
| inetpro | .me should return it to oom Kilos | 18:18 |
| Kilos | iirc correctly i put in a heavier transformer so it could have more guts | 18:18 |
| Kilos | nono i have another one sir | 18:18 |
| Kilos | i built one for incubator only | 18:18 |
| Kilos | thats why i dont remember the voltage | 18:19 |
| inetpro | ok, so how do I connect the router to the battery? | 18:19 |
| Kilos | i think i read he spoke about some dc-dc thing | 18:20 |
| Kilos | router uses 12v? | 18:20 |
| Kilos | or 9v | 18:20 |
| inetpro | it needs to go via the charge controller | 18:20 |
| Kilos | so its 12v | 18:20 |
| Kilos | mine is 9v i think | 18:21 |
| Kilos | you must check that | 18:21 |
| Kilos | router uses those 2 pin charger goodies | 18:21 |
| inetpro | yep, the output is 12V at 1.0 A | 18:22 |
| inetpro | probably using much less than 1A | 18:22 |
| Kilos | yes i think so | 18:23 |
| Kilos | but then it shouldnt be hard to sort | 18:23 |
| Kilos | maybe just a current limiting resistor inline | 18:23 |
| inetpro | "...I measured my router, and it only draws 0.2 Amps on average, which equates to 2.4Wh,” Kurien told Fin24 | 18:25 |
| Kilos | i see my router is 12v at 1.2 amp | 18:25 |
| Kilos | i can try mine direct on a battery and see if it blows but i dont think it will | 18:26 |
| Kilos | if i could see the circuit diagram i could maybre work out if it regulates internally | 18:26 |
| Kilos | does tobie say you need to control the input voltage | 18:27 |
| inetpro | Steca Solsum 6.6F 6A solar regulator is only R 275.00 | 18:27 |
| Kilos | only | 18:28 |
| Kilos | thats my months data | 18:28 |
| Kilos | oh no R199 and some chips hehe | 18:29 |
| inetpro | well, you have something cheaper? | 18:29 |
| inetpro | something that will work when we add the panel? | 18:29 |
| Kilos | add what panel | 18:29 |
| inetpro | 50W | 18:30 |
| Kilos | oh the solar | 18:30 |
| Kilos | no maybe his regulator is a good buy | 18:30 |
| inetpro | yep, 50W PV panel going for R808.00 now | 18:31 |
| Kilos | actually needed | 18:31 |
| Kilos | eish | 18:31 |
| inetpro | but maybe I should just get the 30W | 18:31 |
| Kilos | im waiting for ian to get spares then im gonna try that power from nothing thing | 18:32 |
| Kilos | well you basically need it to charge your battery | 18:32 |
| Kilos | but with the larger battery and ac charger you should be ok for a 3 hour power cut | 18:33 |
| inetpro | BushPower Solar Eco Charger supplies the 30W panel and the regulator for R845 | 18:33 |
| Kilos | thats only needed when power off in the day | 18:34 |
| Kilos | he said he runs his gate opener from this system | 18:34 |
| Kilos | those motors use quite a bit of power | 18:35 |
| inetpro | I'm guessing he has more than one of these setups | 18:35 |
| Kilos | must be ya | 18:35 |
| Kilos | but the savings with solar to charge one battery you wont even notice on your electric bill | 18:36 |
| inetpro | hmm... also true | 18:36 |
| Kilos | so imo its a bit much to spend unless we have days with no power at a time | 18:37 |
| inetpro | but I need to start somehwere man | 18:37 |
| Kilos | did you look at the movie link i put here about 2 weeks back about fuelless power generator | 18:38 |
| inetpro | no | 18:38 |
| Kilos | was a long movie | 18:38 |
| Kilos | 2.5 hours | 18:38 |
| inetpro | and did it help you yet? Have you built your very own home made power station yet? | 18:39 |
| Kilos | using caps and self wound coils ant a steup transformer i think it was you make power that can run pcs and tvs etc | 18:39 |
| Kilos | when ive built one successfully i will feedback | 18:39 |
| Cryterion | http://www.mantech.co.za/ProductInfo.aspx?Item=372M0901 15A Solar charge controller for R170 | 18:40 |
| Kilos | if that works, after first outlay power is free | 18:40 |
| Kilos | sigh man | 18:40 |
| Kilos | im waiting for ian to get components and then find time to bring them | 18:40 |
| Kilos | there thats good for R170 | 18:41 |
| Kilos | 15 amp will charge a battery that it cooks | 18:41 |
| Kilos | way too much so safe | 18:41 |
| Cryterion | yep, 50W panel is nowhere near that | 18:42 |
| Kilos | batteris charge lekker in few hours at about 3 amps | 18:42 |
| inetpro | Kilos: you still need connectors for output to the inverter | 18:42 |
| Kilos | from battery to controller | 18:43 |
| inetpro | for the next step | 18:43 |
| Kilos | then from controller to inverter? | 18:43 |
| inetpro | see http://cdn.24.co.za/files/Cms/General/d/2961/9f4211d6375b466982d79d76b90dd6e3.png | 18:44 |
| Kilos | you can connect inverters straight to battery i think | 18:44 |
| Kilos | oh you bypassing battery | 18:44 |
| Kilos | or not using one | 18:45 |
| Kilos | or is that right top thing supposed to be the battery | 18:45 |
| inetpro | Kilos: read the part "Controlling the charge" | 18:46 |
| inetpro | at http://www.htxt.co.za/2015/02/10/beat-loadshedding-on-a-budget-take-your-tech-solar-for-r1-271/ | 18:46 |
| Cryterion | Remember as well, the cables from battery to inverter must be thick | 18:46 |
| Cryterion | 1 Amp at 240V is the same as 20 Amp at 12V | 18:47 |
| Kilos | jumper cables | 18:47 |
| Cryterion | Yes | 18:48 |
| Kilos | they cheap at checkers | 18:48 |
| Cryterion | those will eventually burn out, depending on how much current your using | 18:49 |
| Kilos | The second piece of kit, the charge controller, isn’t absolutely necessary if you really know what you’re doing, but it is a good idea all the same. | 18:49 |
| inetpro | and the inverter adds an extra load, and will eventually drain the battery even if your gear is off | 18:49 |
| Kilos | i dont think it will be much power | 18:49 |
| inetpro | so the inverter is not something I want to add soon | 18:49 |
| Kilos | ya the inverter is the bug in the whole system | 18:50 |
| Cryterion | Better to have it, will prevent over charging the battery and regulates the voltage supply from the panel | 18:50 |
| inetpro | the laptop can run on its own battery for a long time | 18:50 |
| Kilos | i dont know if pro has decided on the panel yet | 18:50 |
| inetpro | Cryterion: but is that not the job of the rgulator to control the charge of the battery? | 18:51 |
| Kilos | i would first get a battery and voltage controller for router | 18:51 |
| Cryterion | Charge controller and regulator are essentially the same thing | 18:52 |
| Cryterion | If you regulating the panel to 12V then the battery cannot overcharge above 12V | 18:52 |
| Kilos | actually inetpro we need to go back to the start | 18:52 |
| inetpro | ok? | 18:53 |
| Kilos | WAYTTD | 18:53 |
| Kilos | what do you want to run when power off | 18:53 |
| Cryterion | An open circuit 12V panel reads about 19.5V, which means it will keep charging the battery trying to reach 19.5V | 18:53 |
| inetpro | Long term goal: cut the ties from the grid | 18:53 |
| inetpro | Short term goal: stay online when load shedding happens | 18:54 |
| Kilos | you said you must start somewhere | 18:54 |
| Kilos | ok imo shrtterm is battery and voltage controller or regulator | 18:54 |
| Kilos | this for lappy and router right? | 18:55 |
| inetpro | lappy is fine, it's the LTE router that really needs backup power | 18:55 |
| Kilos | you only need an inverter for something that needs 220v | 18:55 |
| Kilos | for router just battery and regulator | 18:56 |
| inetpro | Kilos: well I need to charge from somewhere as well | 18:56 |
| Kilos | sigh | 18:56 |
| Kilos | you have a charger | 18:56 |
| Cryterion | inetpro, does your router have an external plug regulator? I.E. is there 220V or 12V going into the router? | 18:56 |
| Kilos | ac one | 18:56 |
| Kilos | 12v | 18:57 |
| Kilos | Cryterion 12v | 18:57 |
| Kilos | so for minimal outlay | 18:57 |
| Cryterion | Then it only needs to be connected directly to the battery, but better via a 12V regulator | 18:58 |
| Kilos | regulator to feed router | 18:58 |
| Kilos | and cable through wall to outside with crocodile clamps for car battery | 18:58 |
| inetpro | Cryterion: the router has a standard two prong plug charger with input of 100-240V ~ 50/60Hz, 0.5A | 18:58 |
| Cryterion | You could safely go Panel ---> Regulator ----> Battery ----> Router | 18:59 |
| Cryterion | grrrr, then it'll need an inverter | 18:59 |
| Kilos | for? | 18:59 |
| Kilos | all 220 will need inverter | 18:59 |
| inetpro | output = 12.0V at 1.0 A | 18:59 |
| Cryterion | ah | 19:00 |
| Kilos | inetpro can you get your car near window where router is | 19:00 |
| Cryterion | then you can just take out the charger and feed battery direct to the router | 19:00 |
| inetpro | :-P | 19:00 |
| Kilos | power for a router will be fine with flex | 19:00 |
| Cryterion | yep | 19:01 |
| Kilos | to strand flex like for lights | 19:01 |
| inetpro | flex? | 19:01 |
| Kilos | day twee draaitjies wat aan mekaar geheg is | 19:01 |
| Cryterion | inetpro, think of speaker wire, just the cheaper type, called twinflex | 19:01 |
| Kilos | vit lampe en so aan | 19:02 |
| inetpro | link? | 19:02 |
| Kilos | same kinda thing | 19:02 |
| Kilos | speaker wirte | 19:02 |
| Kilos | wire | 19:02 |
| inetpro | ah | 19:02 |
| Kilos | it si on all bedside lamps | 19:02 |
| Kilos | is | 19:02 |
| Kilos | daai goed | 19:03 |
| inetpro | ok, ek verstaan | 19:03 |
| Kilos | checkers has that too | 19:03 |
| mazal | Night everyone , sleep well | 19:03 |
| Kilos | night mazal | 19:03 |
| inetpro | mazal: goeie nag | 19:03 |
| Kilos | sleep tight | 19:03 |
| Kilos | inetpro did you answer | 19:04 |
| Kilos | can your car get near router room | 19:04 |
| Kilos | then you can try before you buy | 19:05 |
| inetpro | where do I get that funny connetor that goes into the router | 19:05 |
| inetpro | ? | 19:05 |
| Kilos | communica | 19:05 |
| Kilos | or any radio shop | 19:05 |
| inetpro | what do i search for? | 19:05 |
| inetpro | and how do I know to get the right size? | 19:06 |
| Kilos | you take the old charger with and show them what plug you want | 19:06 |
| inetpro | hmm... | 19:06 |
| Kilos | then you solder flex inside | 19:06 |
| inetpro | yikes! | 19:07 |
| Kilos | if you go to a radio or tv repair shop they will solder it for you | 19:07 |
| inetpro | ah, good idea | 19:07 |
| Kilos | might even do it free | 19:07 |
| Kilos | maybe even auto electricians | 19:08 |
| kulelu88 | you old-school afrikaaner okes are solid with handywork | 19:08 |
| Kilos | even gremble could do it | 19:09 |
| inetpro | should perhaps make it so it can plug into the cigarette lighter plug | 19:09 |
| Kilos | you can do that too | 19:09 |
| inetpro | then build the other side to connect to the battery | 19:09 |
| Kilos | you get those plugs as well | 19:09 |
| Kilos | huh | 19:09 |
| Kilos | lighter plud on one side and other side the router plug | 19:10 |
| inetpro | ja man, then I can use it interchangably for other purposes | 19:10 |
| Kilos | oic what you mean | 19:10 |
| inetpro | but how do I get just 1A from the car battery? | 19:11 |
| Kilos | so from battery to lighter female and lighter mails for other things you want to connect | 19:11 |
| Cryterion | inetpro, the car lighter is probably capable of about 5A, you'll only draw what the router needs | 19:12 |
| inetpro | ah | 19:12 |
| Kilos | the router will only takes what it needs or you regulator will sort it | 19:12 |
| Cryterion | as long as your supply is higher than the demand then your fine | 19:12 |
| Kilos | car battery can reach way over 50 amps if needed | 19:13 |
| Kilos | just measure when starter starts turning | 19:14 |
| Cryterion | yeah, but the lighter plug is fused, normally about at about5A | 19:14 |
| Kilos | yes | 19:14 |
| Kilos | but not fused the way he wants to do it | 19:15 |
| Cryterion | then he more Amps available :) | 19:15 |
| Kilos | you get inline fuse holders as well | 19:15 |
| inetpro | so don't they sell such a fused lighter plugs with connectors to a battery? | 19:16 |
| Kilos | he will have more availble than what flex can handle | 19:16 |
| Kilos | lol | 19:16 |
| Kilos | the lighter plug gets wired into cars wiring so fuse is on fuse bow | 19:17 |
| Kilos | you could ask a radio/tv repair shop to put a fuse holder in the flex for you | 19:17 |
| Cryterion | inetpro: http://www.mantech.co.za/ProductInfo.aspx?Item=72M3585 | 19:17 |
| inetpro | aha | 19:18 |
| inetpro | thanks Cryterion | 19:18 |
| Cryterion | they might have the other cable, just can't find it on their site, but they'll have all the bits to make one | 19:19 |
| Kilos | sjoe you can build it for much less imo | 19:19 |
| inetpro | that looks exactly like one of the parts that I need | 19:19 |
| Cryterion | just country wide, so should be a branch near you somewhere | 19:19 |
| Cryterion | they, not just | 19:19 |
| Cryterion | that's site price Kilos, I get less 20% on most stuff from them | 19:20 |
| Kilos | oh | 19:20 |
| Kilos | well her must measure the length flex he needs for starters | 19:21 |
| Cryterion | true | 19:21 |
| Kilos | always a bit longer than needed | 19:21 |
| inetpro | so what is it that kills a device? | 19:53 |
| inetpro | is the regulator / charge controller there to rgulate just the voltage? | 19:53 |
| Kilos | no the cureent alowed through | 19:54 |
| Kilos | wbb debs | 19:54 |
| inetpro | ah, obviously those things check the load of the battery and stop charging when it's full | 19:55 |
| Cryterion | Regulators regulate the voltage, but are they themselves are limited to a current rating | 20:25 |
| Cryterion | yes | 20:25 |
| Cryterion | inetpro: when you connect a voltage source to say a flat battery, the source voltage and battery voltage equalise to a state that is higher than that of the battery | 20:27 |
| Cryterion | this voltage continues to rise towards the original source voltage, (Hence charging mode) | 20:28 |
| Cryterion | the charge controller monitors this, and when that voltage reaches the right level, it disconnects the source from the battery, as battery is now full | 20:29 |
| Cryterion | A regulator itself just regulates the voltage, I.E. if the source is above 12V, the regulator only sends out 12V | 20:30 |
| inetpro | Cryterion: ty | 21:02 |
| Cryterion | np | 21:02 |
| inetpro | how do I check the polarity of a coaxial barrel connector? | 21:04 |
| Cryterion | hmmm | 21:04 |
| inetpro | they say center-positive is the most common, but some systems use center-negative | 21:05 |
| inetpro | You do not want to get the polarity mixed up! | 21:05 |
| Cryterion | yeah, sometimes they in verse, normal is centre positive, best way is a multimetre | 21:06 |
| Cryterion | but coaxial cable is normally for signals and not power btw | 21:07 |
| inetpro | hmm... | 21:08 |
| Kilos | ya | 21:08 |
| Kilos | whew | 21:08 |
| inetpro | https://en.wikipedia.org/wiki/Coaxial_power_connector | 21:09 |
| Kilos | you guys getting there | 21:09 |
| inetpro | guess I'm just referring to the common DC power connectors | 21:10 |
| Cryterion | ok, coaxial power connector is normally + centre, often there's a small picture next to the connector (Check on your Router) that'll show you | 21:10 |
| Kilos | ok guys, keep up the good work. see ya tommorrow | 21:10 |
| Cryterion | ok Kilo's, goodnight | 21:10 |
| Kilos | night all. sleep tight | 21:10 |
| inetpro | good night oom Kilos | 21:11 |
| Kilos | lemme know the outcome of all this tomorrow | 21:11 |
| inetpro | haha... | 21:12 |
| Cryterion | inetpro, maybe invest in a multimetre, you can get a cheap working of the shelf one for about R60 at most hardware stores | 21:15 |
| inetpro | Cryterion: I have a small one | 21:15 |
| Cryterion | That's the ideal way to check | 21:15 |
| inetpro | but not sure how I would check polarity with it | 21:16 |
| Cryterion | put the dial onto 20VDC | 21:16 |
| Cryterion | Black probe into GND/COMM and red probe into VAC | 21:17 |
| inetpro | ah interesting | 21:18 |
| inetpro | just can't seem to find this thing now... will look tomorrow and see | 21:18 |
| Cryterion | inetpro: http://www.engineersgarage.com/tutorials/dc-voltage-current-testing | 21:18 |
| Cryterion | ok | 21:19 |
| inetpro | thanks for the link | 21:19 |
| Cryterion | np | 21:19 |
