tija | mithro: Hey How are you? | 06:42 |
*** Bertl_zZ is now known as Bertl | 06:55 | |
mithro | tija: busy | 07:07 |
tija | mithro: haha! I knew. | 08:06 |
mithro | Opsis boards have started production so I'm dealing with issues related to that... | 08:09 |
mithro | xfxf: Camera + Case received | 08:51 |
mithro | xfxf: one the HV30 from eBay also turned up | 08:51 |
xfxf | rad. bring it with you to LCA, i won't need it until then at the absolute earliest | 08:52 |
mithro | xfxf: The case has some positives and negatives | 08:52 |
mithro | xfxf: One primary negative is that it doesn't actually prevent spills from getting into the case | 08:53 |
xfxf | well, most won't, they'll have holes for air given it's a small case | 08:53 |
xfxf | could you look at trying to print a 3d case for it, given you have a printer + there are existing mini ITX designs available? | 08:54 |
mithro | xfxf: The power supply thingy inside doesn't add much either | 08:54 |
xfxf | i'll ask around to see if i can find somebody to help, but i can't guarantee it | 08:54 |
xfxf | mithro: how do you mean it doesn't add much? | 08:54 |
mithro | xfxf: The opsis could just take the power directly from what ever plugs into that | 08:54 |
xfxf | right | 08:55 |
mithro | IE it just needs 12V | 08:55 |
xfxf | i'll need to know where to order reliable power sources though, i've had bad experiences buying power supplies off ebay | 08:55 |
xfxf | yeah i know that, but i'm dubious on ebay quality | 08:55 |
mithro | That power supply provides 3V3 and 5V, etc | 08:55 |
xfxf | yeah, nod, it's meant to power standard ATX boards | 08:56 |
mithro | Yeah | 08:56 |
xfxf | my understanding is the opsis has a ATX power connector | 08:56 |
mithro | It has a 12V PCI-E header | 08:56 |
xfxf | for powering other things, or being powered? | 08:57 |
mithro | being powered | 08:57 |
xfxf | so what do you recommend we do regarding cases. i'm not comfortable making calls on the hardware on my own given this is all new | 08:58 |
mithro | xfxf: well, I haven't had much luck with people designing cases for me | 08:59 |
mithro | xfxf: it's much harder then it seems at first | 08:59 |
mithro | xfxf: but the 3d printed cases for the miniSpartan6+'s I have are awesome | 08:59 |
mithro | xfxf -> https://plus.google.com/+TimAnsell/posts/9BVq3AHdMED | 09:00 |
mithro | xfxf: that is much smaller though | 09:01 |
mithro | xfxf: Power supply quality doesn't matter all that much - it just needs to provide somewhere in the vicinity of 12V (IE things should still work if it was providing 9V or 14V) | 09:02 |
xfxf | oh those 3d printed cases are cool | 09:11 |
xfxf | yeah the problem is all of the cases without PSU's i looked up are about $100 AUD ea by the time they get here | 09:11 |
xfxf | then plus a power supply | 09:11 |
xfxf | plus previous comment too about those existing cases being big and bulky and not something i'd take on a plane with me or to a user group | 09:12 |
xfxf | re the PSU | 09:12 |
xfxf | i'm not clear on the barrel size, polarity, etc | 09:12 |
xfxf | can you provide those specs? | 09:12 |
xfxf | i'll try to find a bunch now to order | 09:12 |
mithro | xfxf: I recommend ordering inline brick style rather than wall-wart style | 09:15 |
xfxf | i'd agree with that | 09:16 |
xfxf | i've just had wonderful experiences with ebay adapters blowing up out of nowhere | 09:16 |
xfxf | but get me the specs and i'll figure it out - '12v barrel' is insufficient | 09:16 |
mithro | xfxf: this style -> http://www.shure.eu/dms/shure/products/accessories/images/wireless/ps124/PS124E_10_cols/PS124E_10_cols.jpg | 09:16 |
xfxf | yep, nod | 09:16 |
xfxf | mithro: those style are geared for much higher watts/amps | 09:22 |
xfxf | mithro: i assume the device won't care if >1a is supplied? | 09:22 |
mithro | nope | 09:22 |
xfxf | curious, why are you against wall warts again? | 09:36 |
xfxf | (it's what the twinpacts use) | 09:36 |
xfxf | mithro: any answer on polarity + size of barrel size? | 09:49 |
xfxf | (i'm downloading kicad now to see if i can figure it out, but if you know, would be helpful) | 09:49 |
xfxf | mithro: what's the 'do not populate' Conference 12V all about in the power diagram? | 09:56 |
xfxf | mithro: the hardware schematic doesn't seem to say a part number, only 'barrel_jack'; from that should I assume you're not sure what the polarity/barrel size is as it's up to the manufacturer? | 10:01 |
