**** BEGIN LOGGING AT Fri Jul 22 02:59:58 2016 Jul 22 04:57:57 thought ya'll might like this: https://www.reddit.com/r/linuxmasterrace/comments/4tvieq/not_quite_a_screenshot_one_more_hello_world_to_lmr/ Jul 22 04:58:00 featuring the bbb Jul 22 07:08:10 need an lcd for BBB. Probably will buy it from here http://www.rhydolabz.com/displays-c-88/7-inch-touch-lcd-cape-for-beaglebone-black-p-2175.html Jul 22 07:08:21 any thing you would like to suggest > Jul 22 07:08:22 ? Jul 22 07:08:34 like it wont work with the latest kernel or such ? Jul 22 08:16:09 ZeekHuge: I bought LCD 7'0 from 4DSYSTEM. It don't work with the last version bone kernel Jul 22 08:16:19 *doesn't Jul 22 08:16:51 dirkk, is it hdmi? Jul 22 08:20:30 belgin you just plug the board behind the LCD screen Jul 22 08:20:46 oh i see Jul 22 08:21:22 belgin ZeekHuge http://www.4dsystems.com.au/product/4DCAPE_70T/ Jul 22 08:28:38 dirkk, my hdmi monitor only works with bbb and the latest linux if I plug the hdmi cable AFTER x starts Jul 22 08:28:45 not at power-on Jul 22 08:29:10 not sure about your lcd Jul 22 08:38:43 belgin what are you doubts ? Jul 22 12:36:48 http://uk.rs-online.com/web/p/processor-microcontroller-development-kits/8874764/ Jul 22 12:44:13 whoa, X15 available in numbers? impossibru! Jul 22 13:28:39 OOoooo. Jul 22 13:30:36 don't wet yourself Jul 22 13:30:37 ;) Jul 22 14:23:17 broke the mini usb port :-( Jul 22 14:26:06 soldering seems really tricky on these pins Jul 22 15:40:08 av500: so what was changed in B1 ? any idea? Jul 22 15:40:12 the hw docs aren't up yet Jul 22 15:42:09 meh, why do they show prices with VAT if they only sell to companies Jul 22 15:42:36 can anyone tell me why i'd want the A2 version of X15 board Jul 22 15:42:41 instead of the one now released? Jul 22 15:42:49 you mean the B1 Jul 22 15:42:51 or Jul 22 15:42:53 ty Jul 22 15:43:20 because of the CE/FCC logo stamped on it ;) Jul 22 15:43:35 i hold no respect for authorities Jul 22 15:43:51 so, beside that? :D Jul 22 15:45:05 hehe Jul 22 15:46:43 well the emission limits do exist for a reason of course, the amount of EMI crap floating around in your neighbourhood will to some degree affect wireless communications and noise/interference in other hardware Jul 22 15:47:03 then again I suspect that at nurdspace there's already plenty of that going around ;P Jul 22 15:47:48 ;) i'm convinced yeh Jul 22 15:47:55 assuming they didn't somehow manage to make a high-powered transmitter by accident, I suspect it's fine Jul 22 15:49:39 zmatt: no idea Jul 22 15:52:45 IIRC it was something about the HDMI. Framer or trace routing or such. I forgot the details Jul 22 15:54:45 buZz: so could also be that too noise external noise gets transferred onto hdmi, or it isn't sufficiently robust against noise received via hdmi Jul 22 15:55:31 much* Jul 22 15:55:36 yeah Jul 22 15:55:39 :) Jul 22 15:55:46 well, curious Jul 22 15:56:02 excessive emissions seem most likely to me though Jul 22 15:56:15 hell, the BBB passed the tests with <1 dB margin Jul 22 15:58:32 yes, I'd also expect emissions to be the problem Jul 22 15:59:17 you might get away by putting it in a proper metal case. ofc there is still some stuff going to escape via cables and such unless you go all out ferrite Jul 22 16:00:28 or just by not caring. I suspect the probability is very low that some people in suits show up "yes we've detected emissions that exceed the legal limit by 2 dB and triangulated it to this location" Jul 22 16:01:04 oh, that for sure Jul 22 16:01:24 I meant more "if you care or have other rf sensitive things around" Jul 22 16:03:25 :D Jul 22 16:03:37 i kinda expect random microwaves to already output such levels Jul 22 16:03:47 buZz practically lives at a hackerspace... I don't think anything rf sensitive would feel very comfortable there anyway Jul 22 16:04:03 >:) Jul 22 16:04:25 would be nice to RF harvest some power for leds, make a big chandelier with it Jul 22 16:04:39 visualizing EM basically Jul 22 16:07:46 something with an RF diode and then... dunno Jul 22 16:08:55 ideally it would collect energy into a cap and then discharge it when it holds enough energy to give a noticable blink Jul 22 16:09:36 maybe there is enough in the air to actually power a led, I'm not sure really Jul 22 16:14:24 some crazy people have done that, but used a magnetron from a microwave to illuminate it with RF Jul 22 16:14:31 if my quick calculation is right, space filled with a uniform travelling wave of 1 V/m field strength (rms) has an energy density of 2.65 mW / m^3 Jul 22 16:16:00 of course if you make a device that manages to absorb all energymagnetic energy that hits it (and even turn it into usable energy), the military will be interested to have a chat :P Jul 22 16:16:01 http://www.getfreevolt.com/ Jul 22 16:16:28 https://www.youtube.com/watch?v=g91xkISmp2g - don't try this at home, kids. Jul 22 16:17:26 buZz: Tesla would be proud :P Jul 22 16:18:50 no mention of the amount of power they expect to be able to extract? Jul 22 16:20:06 i assume near nothing Jul 22 16:20:10 so suitable for a led :P Jul 22 16:20:18 i think i just signed up for a devkit Jul 22 16:20:26 :P Jul 22 16:22:40 hehe Jul 22 16:25:05 a bit curious though, can you simply sell a non-CE/FCC certified board like that? Jul 22 16:25:16 they don't even mention the fact on the site Jul 22 16:28:58 maybe there is something in the box Jul 22 19:57:43 awesome, 5pm meeting on a Friday. Stupid left coasters. Jul 22 19:57:52 heh, wrong window Jul 22 20:18:39 hahahaha Jul 22 20:47:09 i'm going to start scheduling 8am EDT meetings ;) Jul 23 00:24:49 hah, lol what... I thought it was already bad the am335x ROM loads MLO at a non-page-aligned address, but apparently omap4 uses an address which isn't even 32-byte aligned (hence not suitable for using as vector base) Jul 23 00:33:55 (at least that's what u-boot's armv7/start.S seems to suggest, don't immediately see any reason for it in TRM, but oh well) **** ENDING LOGGING AT Sat Jul 23 02:59:58 2016
