mithroI wonder why it's borked on travis - I'm guessing an older / crappier version of patch or something05:38

CarlFK[m]Kamilion (IRC): you know stuff.  we need 10ish 12v 3A PSs of this form factor.  any comments on if we should spend the extra $ $16 Asus brand or $7
rohitksinghmithro: would you like to look into that? I have next to zero experience with travis05:42
mithroYeah I'll dig into that05:42
KamilionSo, two things, are you intending these for use with EEE PCs?05:42
Kamilionyou linked me to two different supplies; one of which has a 5.5mm barrel, the other has the specific jack for the smaller EEEPC netbooks (like mine)05:44
Kamilionone of which was 19V, not 12V.05:45
Kamilionif 12V is what you need, with a 5.5MM barrel, I have a large cache of those. If the 19V with the pinprick EEE connector is what you need; you'll need to be more specific with the model ID you want to plug into; as there's 12V, 14V, and 19V variants.05:46
KamilionThese are what I've got on hand:
Kamilionthey're physically larger and more rugged than you requested, but it's unlikely they'll ever develop a fault.05:50
Kamilionthey are switching adapters; they will only supply what you draw; so if 3A is all you need; these will be incredibly stable power rails.05:50
Kamilionit's unlikely they'll even get warm at half their rated load.05:52
Kamilionhowever, they're also physically quite heavy as well, so they're not especally well suited for traveling in that reguard.05:53
CarlFK[m]Kamilion (IRC): I need 12v and the dimintions  of the asus one05:56
Kamilioni have a few leads to spare with anderson connectors on them05:56
CarlFK[m]I will likely cut off most of the cord.  it is to go inside the case and power an Opsis05:57
Kamilionbut I'd suggest just purchasing the cheap ones and salvaging the cable off it.05:57
rohitksinghmithro: can I come over and look into how you work with travis?05:57
Kamilionthe molded cable-end is high quality on most of them05:57
Kamilionyou shouldn't need to destroy original asus supplies just to salvage those05:58
mithroSure - I'm just finishing up an email....05:58
CarlFK[m]Kamilion (IRC): I need the 7c? 2 prong power plug to line up with a db9 hole on the case05:59
CarlFK[m]I have the asus ps here, and it just fits.05:59
Kamilionthey've got panel connectors with leaf-edge locks05:59
rohitksinghmithro: ok. ping me when you start work on travis...06:00
Kamilionlet me take a photo of the cable in question06:00
CarlFK[m]that's the bit I will throw out06:02
Kamilionoh? Be very careful what you buy then06:02
micolousCarlFK[m] wants an IEC 60320 C8 socket06:02
Kamilionthe asus supplies are 19V06:02
Kamilionnot 12V06:02
micolousWhich takes in a C7 cord06:02
Kamilionwhat, this?06:03
micolousYes, so the power supply would sit inside the case and have one of those sockets, and then 12v on the inside06:04
tpbTitle: 100 Pcs AC 250V 2.5A C8 Type Screw Mount Power Jack Socket Black - Free Shipping On Orders Over $45 - - 24400429 (at
Kamilionthere you are06:04
Kamilion100 pieces for $2606:04
micolousWe need the complete PSU ;)06:04
Kamilionagain, the asus PCBs are for 19V06:05
Kamilionbe mindful you get the right one06:05
Kamilionasus made those netbooks for about six years06:06
* CarlFK[m] uploaded an image: VectorImage_2018-01-14_050147.jpg (4601KB) <>06:06
Kamilionand there's at least ten different variations on the different sizes and models06:06
Kamilionfrom the little 7" netbook to the 12"06:06
KamilionI see the photo, and I understand06:08
Kamilioni'll also point out it's a safety hazard, but it's a one-off so who cares06:08
Kamiliondo not advise others to do this06:08
Kamilionbut if the original asus supply you have does the job, buy more.06:09
Kamilionyou cannot rely on the vendor to give you the same stock more than once06:09
Kamilioni ran into that issue while using EEE netbooks in the field.06:09
Kamilionalso, car adapters that can boost to 19V are infuiriatingly hard to come by06:10
Kamilionwhich is where I salvaged that cable from; and it is the last of my stock from those times06:10
Kamilionso, if you're after that specific asus R33030, buy all you need at once06:11
Kamilionas long as it's from a US vendor you'll probably get what's in the picture06:12
Kamilionif it's from an ebay international vendor in china, there's a good chance you'll get a "R33030 compatible" in any manner of shape or size.06:12
Kamilionthe asus branded supplies are probably going to hold tighter regulation and contain better quality components06:13
Kamilionhalf the asus supplies I ordered had some amount of rattle inside06:13
Kamilionso be sure you pick up at least two or three more than you think you need06:13
Kamilionhalf the EEE supplies I ordered had some amount of rattle inside06:14
KamilionAlso, if you're gonna mount the PSU inside the case; use the industrial velcro instead of double sided sticky tape.06:15
Kamilionit doesn't have a tendancy to float like the cheap walmart velcro strips06:15
Kamilionget it from home despot06:16
Kamilionfuzzy side on the supply, pokey side in the case.06:16
Kamilionuse more than you think you need.06:16
Kamilionthe heat from the running power supply will make it nigh-impossible to remove afterwards06:17
Kamilionvelcro also transfers heat better than you'd think06:17
CarlFK[m]some amount of rattle ?!06:22
Kamilionyeah. Component fell off the board. plastic latch snapped off...06:23
Kamilionthe usual.06:23
Kamilionwhat, you've never ordered shit from aliexpress?06:23
KamilionQA can be nonexistant sometimes for a lot of the under $10 products06:24
Kamilionsometimes you get lucky, sometimes it's the electronic equivoloent of a steaming turd on your doorstep06:24
Kamilionother vendors have gone beyond just cloning; and actually offer solid product for not much more than the price of components06:25
Kamilionbut some of them just have no idea what they're doing at all06:25
KamilionI'm sure it's gotten better now -- those are rather older memories and the Maker movement is in full swing now06:25
Kamilioni've still got a few orders in dealextreme's history that go back to something like 2007/2008 I think06:26
KamilionWell, good luck on your kitbashing adventure, I'm gonna go to the store and be afk for an hour06:27
Kamilionhighlight me if I can be of further assistance.06:28
