<nicksydney> got the inductor but the footprint i'm using is too small for me to solder it properly...so doing it manually inside PcbNew
<wpwrak> design a bigger footprint ? or add a new size option to an existing one ?
* wpwrak notices that it's very hard to get people to try fped. once they've used for a few minutes, they love it. but getting them to make the first step is nearly impossible.
<larsc> same as with heroin
<viric> if you look only at similarities, almost everything is the same
<nicksydney> wpwrak: making the footprint larger inside PcbNew ..if it works out than will create a new module with different footprint
<wpwrak> heroin, the universal similant. now there's a new thought :)
<wpwrak> nicksydney: are you using footprints from the kicad libs or from qi-hw'
<wpwrak> s kicad-libs project ?
<nicksydney> wi0h
<nicksydney> qi-hw
<wpwrak> then you already have the original in fped
<wpwrak> you're using iunductor-2p-3mmx3mm ?
<nicksydney> yeah
<wpwrak> try cd kicad-libs/modules; fped inductor-2p.fpd
<wpwrak> see the nice little table ? :) just has one row at the moment, but there could be lots and lots more :)
<wpwrak> size{x,y} is the component size; p{x,y} is the pad size; gap is the space between the pads
<wpwrak> move the divider to the right or increase to full-screen
<nicksydney> ok i've increased the px and py
<nicksydney> but it did not chnage
<wpwrak> did the background turn blue ?
<nicksydney> px turns to magenta
<nicksydney> and at the bottom there is a green bar where i can enter the value
<wpwrak> yup. don't forget the mm
<nicksydney> ahh ok
<nicksydney> it works
<wpwrak> if you forget the unit, then it prints an error in the status line at the very bottom and the background of the drawing turns blue
<wpwrak> (and it doesn't update the drawing)
<nicksydney> so once i save it ...and go back to kicad it will refresh ? or any other steps i have to do ?
<wpwrak> naw, don't change the existing entry. else you'll lose the old footprint.
<wpwrak> quit, restart, and make a new row instead.
<wpwrak> or is your inductor 3mm x 3mm, too, just differing in px/py ?
<wpwrak> what's the part number anyway ? (or datasheet link)
<nicksydney> hang on let me get the datasheet
<nicksydney> it's the LQH4C Type
<nicksydney> LQH4C6R8M04
<wpwrak> ah, you're on the wrong footprint with this
<wpwrak> these come in standard sizes. so this one is an 1812. lemme see if we have that already ...
<wpwrak> yup. just use 1812 from stdpass.fpd
<nicksydney> 1812 or 1812P ?
<wpwrak> it's not polarized, so just 1812
<nicksydney> ok let me print it out now
<nicksydney> ok much better than the one i did manually :)
<nicksydney> cool
<nicksydney> learn something new today about a chip called Super I/O ... only on x86
<nicksydney> nifty little chip from this company http://www.fintek.com.tw/eng/products.asp?BID=1&SID=17&layer=0
<nicksydney> wonder if in ARM world they have something similar
<nicksydney> apparently can do HW monitoring too
<whitequark> Super I/O is the remnant of the 8086 era
<whitequark> basically a kitchen sink of various compatibility shit they have to still carry around
<whitequark> proper CPUs simply shed that nonsense when it becomes obsolete
<nicksydney> what i find interesting is the HW monitoring part
<whitequark> look up ARM PMICs
<nicksydney> cool thanks whitequark
<nicksydney> ahh Power Management Integrated Circuits (PMICs)
<nicksydney> spoke too soon that's not BLE
xiangfu has quit [Remote host closed the connection]
<wpwrak> actually, it is. "BT Smart" is the new official name for "BTLE"
<whitequark> *facepalm*
<wpwrak> whether the idea of replacing a nice and descriptive name with something vague and generic is really a smart idea, seems somewhat dubious
<nicksydney> ohh....interesting they change the name..making people more confused
<whitequark> wpwrak: well it sure sounded well to marketing guys
<wpwrak> in think the official acronym for BTLE was actually "BLE". but that also robs is of the distinctive "BT" prefix.
<whitequark> that's basically their job, replacing nice and descriptive with vague and confusing
<wpwrak> so i just use a more understandable and descriptive acronym ;-)
<wpwrak> yeah, they exceeded themselves in this case

<wpwrak> it's somewhat galling that those certainly very smart people who make FETs had to place GSD (Gate, Source, Drain) counter-clockwise for single FETs, but clockwise in dual packages
<wpwrak> this means that when going from single to dual, not only the dimensions but also the topology of the circuit changes
jekhor__ has joined #qi-hardware
<wpwrak> that is, unless ... hack, hack ... yeah, compatibility achieved in one case
<wpwrak> let's see if i can do the other one, too

<apelete> Hi larsc
jekhor__ has joined #qi-hardware
<larsc> hi
<apelete> larsc: got a minute ? would to share some debug thoughts with you
<larsc> but only one
<apelete> :)
<apelete> seem like EIO is set by drivers/mmc/card/block.c
<apelete> don't know if that makes sense
<apelete> when mmc_start_req(card->host, areq, (int *) &status); fails, it goes into MMC_BLK_RETRY states 5 times in a row before going into MMC_BLK_ABORT
<apelete> that's where it seems to set EIO with blk_end_request(req, -EIO, blk_rq_cur_bytes(req));
<apelete> not sure about that, so I also stepped through jz_mmc_irq() in mmc driver (that's one of the two codepath in the mmc driver that also set EIO)
<apelete> it didn't triggered the EIO codepath though
<apelete> so last thing to do would be to step through jz4740_mmc_transfer_check_state() which has another EIO codepath
<apelete> and see if ot actually triggers an IO error (and if it is linked to drivers/mmc/card/block.c at some point)
<larsc> do you know why mmc_start_req fails?
<apelete> nope
<apelete> should I look into that ?
<larsc> yes
<apelete> ok, will do so
<apelete> larsc: thanks for your time :)

<nicksydney> the RA8875 has been shipped from taobaoring.com by EMS so hopefully in 2 days time it will reach...interesting to see if i get what i paid for :)
<nicksydney> according to EMS tracker it's in Beijing right now
<nicksydney> Video: Putin hits the ice to compete with legendary hockey players -- https://www.youtube.com/watch?v=TUdYCzdpzdY&feature=player_embedded
<nicksydney> better make sure you don't get in the way of Putin when he is playing hockey :)
<nicksydney> wpwrak: found this company (website) that can print things out based on your design in NZ https://www.ponoko.com/
<nicksydney> they have leather, paper, plastic, wood, cardboard
<nicksydney> "PETG is a clear thermoplastic polyester with a glossy finish." sounds sexy :)
<wpwrak> a local shapeways ?
