00:01.24Turlfocus_it: you just need usb power to power them up though?
00:01.28focus_itI have MK802 talking when it receives RS232 signal. Anything text it sees between <s> text </s>, it will speak out!
00:01.51Turlheh :)
00:01.58focus_itTurl: need 2 x monitors to see what they do. I have 30" and 24" already on desk doing other stuff
00:03.29focus_itnot for public release - image for MK802 with gambas here http://www.gplsquared.com/mk802/mk802.html
00:03.39Turlfocus_it: replace them with A10 tablets with screen :)
00:03.47Turlgonna be cheaper than a monitor :P

10:36.58slapinhno: I tested HP 16500C with 16550A logic analyser on NAND, but was too lazy to solder all the pins, so I don't see how yours LA doesn't work - HP has only 4KB per channel. I soldered ALE, CLE and CE and see all the output.
10:37.09slapinhno: and NAND still works...
10:38.16slapinhno: by the way, I seem to have the same problem as you now - cold booted hw doesn't see nand but otherwise operational - it seems fclk failure... I don;t see other explanation.

11:59.04slapinhno: do you have any success with LA?

12:41.53gzambonifocus_well interesting, do you know if it works well ?
12:46.17slapinfocus_well: they don't ship to .ru
12:46.47slapinfocus_well: I always wanted something like this
12:47.29slapinfocus_well: I use hot iron for bigger BGA chips
12:47.53slapinfocus_well: bigger = higher pitch like DDR SDRAM chips
12:48.16slapinfocus_well: but this is very hard and complicated task
12:50.37gzambonii dont understand, it says £139.00 and after: Manufacturer Suggested Retail Price:2599USD
12:50.47gzambonithere is a huge difference
12:51.53focus_wellgzamboni: it works well with taking off chips - exactly on their video at ebay page
12:52.42focus_wellsoldering chip - i have not tried because we have engineer here who does 'drag soldering' to solder 100 pin+ chips
12:53.11focus_wellwe don't try BGA as policy - but A10 is bga, so we must, so I buy device and hope to start using it for bga
12:54.35slapinfocus_well: hw with BGA is too expensive to produce here - RND costs are too high for hobbyists / small hw companies
12:54.58gzambonithe same here, at the moment i dont use bga anywhere, but a10 and a10s are only bga
12:55.01focus_wellslapin: I think the device is good enough for nand and bga chips
12:55.08slapinfocus_well: making good boards takes time and lots of money
12:55.25focus_wellI believe this is game changer if bga soldering is possible with this machine
12:55.41focus_wellI see many different bga soldering techniques on youtube - none as good as this!
12:55.58focus_wellbut getting it right is no easy matter
12:55.58slapinfocus_well: if you want sample boards, you have to pay 400-500 euros each iteration at minimum
12:56.31slapinfocus_well: soldering is easy and cheap with right equipment, but making board is too expensive
12:56.52focus_wellslapin i believe i can get it done for $250 in CN - but still way too expensive
12:57.04gzamboniits a top rated seller, this means its right what he sells
12:57.57gzamboniif you do the routing and buy 10 samples pcbs with all the equipment
12:58.21gzambonianyone konws www.ourpcb.com ?
12:58.29gzamboniits CN, i want to try them
12:59.01focus_welli have laser that can cut stencil mylar sheet for bga. this stencil normally steel - so I don't know how good it will be.
12:59.43focus_wellWith stencil you apply solder paste. Then place bga on top, then use this lamp, 7 to 10 flashes and its soldered!!!!!!!
12:59.55focus_wellThats what I'm hoping can be achieved
13:00.41focus_wellI do KiCAD and do all routing.

13:01.29gzambonithe laser cut should be expensive, i dont have one ...
13:01.52gzamboniwould have to buy the A10 stencil from somone
13:01.59focus_welllaser to cut mylar sheet is about $800 in alibaba.com

13:06.21focus_wellbut acrylic can't get thin sheet.

13:07.28focus_wellI tried it, and i believe the stories, though I don't know if its good enough for bga
13:07.45focus_welland this lamp system
13:10.23slapinfocus_well: sometimes some stencils can be made or made from others by hand
13:10.56focus_wellyes that ok - but remember bga is small and alignments critical
13:11.25slapinfocus_well: solder paste doesn't requie that much precision
13:12.02focus_wellslapin:  I can make you stencils if you send me paypal payment :-) - but let me get it right first!
13:12.12slapinfocus_well: also, you can generally have this applied when ordering board, so solder paste will not be required for BGA soldering
13:12.49focus_wellslapin: that good idea!! Get the factory to do it!!
13:12.51slapinfocus_well: my stencils are cheap at the moment, $20 each for SDRAM.

13:13.23focus_wellif its mylar I can do them for $1 :-)
13:13.38slapinfocus_well: other SMT can be soldered without stencils by hand and normal solder
13:14.09focus_wellyes - its the bga, nand, ram that worry me
13:14.09slapinfocus_well: mine for auto-smt for the whole board
13:14.58focus_wellthe factory I work with in CN can make 10,000 SMT boards in 3 days - so no problem scaling once boards are right
13:15.08slapinfocus_well: RAM is simple, cpu is hard. NAND can be soldered via cheap smt station after a few tries and good flux
13:15.54focus_wellour engineer here uses 'drag soldering' technique - 100 pin chips he can solder in one minute!
13:16.49focus_wellits a special solder tip with a cup in the middle of the bit to hold a solder reservoir
13:17.17slapinsolders TSOP packages in less than a minute with 2 magic passes, good USA-made flux and normal conic solder tip
13:17.45focus_wellOK with TQFP packages - but LCD connector is hard for him to do

13:30.16slapinfocus_well: yeah, and good flux is expensive
13:31.27slapinfocus_well: I don't have it at hands, will check the name
13:31.40focus_wellthanks
13:32.31slapinfocus_well: but for molex connectors I'd recommend hot iron at 350 degrees, or fan from other side of board.
13:33.17slapinfocus_well: because if you manage to get flux into connector they it is goner
13:34.06slapinfocus_well: you have to use good hard drawing brush to put flux on board when soldering these
13:34.31focus_wellI buy two types of iron - low energy and high frequency
13:35.05focus_wellthe low energy is about 15W and perfect for SMT - not enough energy to overheat SMT
13:35.33slapinfocus_well: for iron I mean the one you use to make socks more smooth...
13:35.42slapinfocus_well: not soldering one
13:36.27focus_wellthe 'high frequency' soldering iron updates the temperature of the iron about once every second or higher frequency - because of that the iron is held at precise temperature it is set to instead of wandering too much
13:36.32focus_welloop!
13:38.24focus_wellI think I know that technique - someone say use electric cooking plate, heat it up to high temperature, turn it off, place board on cooking plate at right time, and does perfect soldering without burning
13:38.46focus_wellbecause the cooking plate is cooling all the time.
13:40.21slapinfocus_well: don't forget that it is quite hard to change temperature fast without cooling system and precision is quite bad. I don't see how high freqency measurement can help here
13:41.05slapinfocus_well: my friend uses gas oven as reflow oven for last 7 years
13:41.34slapinfocus_well: that doesn't mean he wouldn't buy real oven if he could
13:42.30focus_wellnormal soldering iron has a big lag between on and off and so it always overheat or is too cold and stick. A high frequency iron when set to say 327 degrees will be at that temperature +/- 3 or so degrees
13:43.24focus_wellReal reflow ovens are about $600. But they have a fan that pulls the fume out - so need to have a big pipe to vent it outdoors or get poison fumes in the room
13:43.47focus_wellI buy one, but not use it yet
13:44.12focus_wellbecause of the need to fit the pipe through window
13:46.46*** join/#arm-netbook cat_x301 (~cat@gprs-internet-ff9bee00-214.dhcp.inet.fi)
13:48.59slapinfocus_well: fumes are not that big a problem, not more that what you get if you just solder it by hand. unless you're going to start mass-production
13:50.03slapinfocus_well: reflow ovens start at $400, but here I have to pay $1400 shipment fees for travelling overseas and customs fee of unknown value
13:51.38slapinit is very hard to get professional equipment in .ru these days
13:51.50focus_wellI understand - i have similar problems starting business in some countries. if its not the high fees, its the corruption. always loose money.
13:52.10focus_wellget fed up and do business elsewhere
13:52.27slapinthere are a few DIY projects using domestic IR grills, but too much trouble to implement
13:53.39focus_wellsome countries are poor because the problems start at the port and for NO other reason.

16:33.29valhalladrachensun: I'm looking at the pengpod and I'm wondering: how hard would it be to remove the capacitive touch screen and put an easily available resistive one? (assuming one is confortable opening devices, but not very skilled wiith soldiering)
16:38.27*** join/#arm-netbook rsalveti_ (~rsalveti@linaro/rsalveti)
16:42.17drachensunvalhalla: I think it would be very difficult for a number of reasons.  First, I think its adhered to the LCD, second, the way resistive and capacative screens are controlled is very different and the pins to the A10s built in resistive controller are not wired out so you would have to install a new controller chip and hack it into the i2c bus somehow then bring in a driver for it
16:42.47drachensunI'm curious, why would you want a resistive screen?  Generally capacitive is much better.
16:45.28mnemocin more industrial with apes operating the devices resistive works better
16:45.37mnemoc+envs
16:47.09drachensuninteresting, I've wondered how strong the effect was
16:47.50drachensunwe researched it for a vending machine application before, mounting the touch on the outside and having an air gap between the LCD to prevent shock from reaching the glass
16:47.51valhalladrachensun: mostly to be able to use it with a (non extremely expensive) pen. Also I find that the "capacitive is much better" is not always true, unless you're talking about android where you have to have multitouch for the interface to work
16:47.57drachensunbut the parallax became an issue
16:48.50valhalladrachensun: my experience is that resistive tend to be quite better than capacitive at precision
16:49.29drachensunvalhalla: There are capative styluses, stylii, not sure what the plural is, but for not much these days.  I used to carry some that were $2, they were pretty good for drawing games like "draw something" on Android

16:54.31drachensunyeah, I've been thinking about applications like that.  I was hoping to find some software to use the tablet as a 'drawing' tablet for a desktop PC.  Its been so busy though I haven't even had a chance to look.
16:55.07drachensunmnemoc: ugh that is pretty annoying
16:55.11mnemocvery
16:57.05drachensunvalhalla:  So for your project app, how would you output to the projector? with the HDMI?
16:57.09valhallafor drawing, resisitive usually has some kind of pressure sensibility (usually just a few levels), AFAIK capacitive are mostly using the size of the finger
16:57.14valhalladrachensun: yes, with the HDMI
16:57.27drachensunright now it can't do both the LCD and HDMI at once
16:57.31mnemocafter the 3rd try to press a button you start thinking about throwing it out of the window
16:58.34drachensunI'm not sure the TS would work right in HDMI mode, I think the script.fex would need the size parameters adjusted in both locations, probably will work though
