**** BEGIN LOGGING AT Mon Jan 21 02:59:56 2019 Jan 21 12:30:17 Hi, I'm having a hard time locating any docs on the IPU system onboard the BeagleBoard X15, does anyone have a good starting point for reading about it? Jan 21 13:35:16 JohnT: IPU? do you mean IVA? or GPU? Jan 21 13:35:30 ah, never mind, IPU is the Cortex-M4 cores Jan 21 13:35:43 JohnT: the TRM should have lots of info on the Cortex-M4 cores Jan 21 13:35:59 JohnT: and Code composer studio lets you target them Jan 21 13:36:14 or you can use your favorite other compiler, like gcc which should work fine too Jan 21 13:38:44 JohnT: see chapter 7 in http://www.ti.com/lit/ug/spruhz6k/spruhz6k.pdf Jan 21 13:42:00 bradfa: yes I have read chapter 7, it is a bit intimidating, I worked with the TM4C123 series before. What I can't seem to figure is how to bridge the gap and actually loading the binary into the system? Jan 21 13:42:31 bradfa: And thank you :) Jan 21 13:44:04 JohnT: all of am572x is a bit intimidating :) Jan 21 13:45:25 JohnT: you want to boot an IPUx subsystem from Linux or from bare-metal? Jan 21 13:46:24 bradfa: From Linux Jan 21 13:46:37 JohnT: have you read http://www.ti.com/lit/an/sprac60/sprac60.pdf Jan 21 13:46:52 JohnT: that's teh "TI way" of doing things Jan 21 13:47:28 JohnT: there are many ways to start the M4 cores Jan 21 13:48:30 JohnT: also see http://processors.wiki.ti.com/index.php/RPMsg_Quick_Start_Guide and http://processors.wiki.ti.com/index.php/Linux_IPC_on_AM57xx Jan 21 13:49:11 bradfa: Thanks a lot, I wasn't able to find at least two of the articles you sent me Jan 21 13:49:52 JohnT: you can also just hand Linux command line a "mem=" line to limit Linux's use of RAM above a set point and then use /dev/mem to play Jan 21 13:51:48 JohnT: /dev/mem when hitting addresses which are within DDR won't be "fast" but it can get you going if you don't want to deal with cmem or cma or remoteproc or any of the other ways of loading/starting/communicating between the processor subsystems Jan 21 13:53:34 bradfa: So the IPU can share DDR with the core running linux? Jan 21 13:53:51 JohnT: yes, you just have to use some mechanism to ensure that Linux doesn't think it can use that DDR for other things Jan 21 13:54:18 JohnT: that's where cma/cmem come in, or just limiting Linux with a "mem=" command line parameter and then only using above that point for your IPU/DSP things Jan 21 13:54:52 JohnT: each IPU also have it's own local SRAM and caches, but they can execute out of DDR too Jan 21 13:54:59 and access DDR Jan 21 13:55:35 JohnT: only restriction on DDR access is if your board has more than 2 GB of DDR, then only the Cortex-A15 cores can see above the 2GB point due to the way the L3 interconnect works Jan 21 13:55:50 most borads don't have more than 2GB Jan 21 13:57:39 bradfa: Thats very cool. And intimidating Jan 21 13:58:15 JohnT: yeah, am572x isn't the easiest thing to grok, but don't worry, am65xx has twice as long TRM and it doesn't even have any DSP cores :) Jan 21 13:59:59 bradfa: Is there any Beagleboard x30 coming or something? Jan 21 14:00:09 JohnT: sorry, don't know :( Jan 21 14:02:18 bradfa: I'm working a servo control system as a part of a larger distributed system, and I thought the beagleboard seemed fit for the job, but it seems rather tedious to get all the parts up and running compared to a linux SBC + serial link to a MCU. Jan 21 14:03:14 JohnT: it depends on your use-case and how much you care about cost and integration and a bunch of other things, but yeah, if you don't need the DSP(s) in am57xx then it might not be worth it Jan 21 14:03:38 JohnT: have you looked at using the PRU cores in AM335x to do your motor control and run Linux on the Corrtex-A8 there? Jan 21 14:03:56 JohnT: am335x is less intimidating and quite a bit cheaper Jan 21 14:04:48 JohnT: I'd also say you could look at the NXP/Freescale Vybrid parts, they have Cortex-A with Cortex-M integrated, for pretty cheap prices Jan 21 14:06:24 bradfa: Maybe I should look into those systems, price is not really an issue, I had thought that the x15 would be much easier too work with. Jan 21 14:07:10 JohnT: it just depends on how much investment you want to put into learning Jan 21 14:07:48 JohnT: if you're making a product and you have low volumes, and you don't need the DSPs, I'd advise to not use AM57xx and find something simpler/cheaper. But if you need the DSPs then it's really hard to beat the price of AM57xx Jan 21 14:09:05 bradfa: Thanks a lot, its a relatively low volume product we are working on, so maybe I should reconsider using another board. Jan 21 14:09:26 JohnT: beaglebone is easier to get goign with, if it'll meet your needs Jan 21 14:10:03 JohnT: and there's lots of SoM (system on module) vendors with AM335x parts, and you can also look at the Octavo part used on the pocket beagle for your own board design Jan 21 14:10:08 https://octavosystems.com/octavo_products/osd335x/ Jan 21 14:10:37 https://octavosystems.com/octavo_products/osd335x-sm/ Jan 21 14:14:10 JohnT: if your motor control needs can be met with the PRU, they are pretty simple to grok, you'll have the least frustration if you get an overview of how they work and understand the instruction set and capabilities first. TI has some good training on the PRU Jan 21 14:22:47 bradfa: Is the PRU System on the Beaglebone easier to use then the X15 or is it the same? Jan 21 14:23:10 JohnT: the AM57xx PRU cores are slightly more advanced than those in AM335x, let me find the guide one sec Jan 21 14:24:13 JohnT: see this doc http://www.ti.com/lit/an/sprac90c/sprac90c.pdf Jan 21 14:25:13 JohnT: iirc, if you have code for am335x PRUs then it should be able to run with only minor changes on am57xx but I haven't tested this Jan 21 14:25:51 JohnT: PRU subsystem on AM65xx is even further advacned and integrates a bunch more Ethernet things, if you care about that Jan 21 14:35:18 bradfa: Thank you so much for all this information it will be very useful Jan 21 14:36:55 yeah the pru examples included with py-uio run on both am335x and am57xx without modification, since they don't have any specific hardware dependencies Jan 21 14:39:16 bradfa: it's so weird that am6 is a keystone (3?) processor without any DSP... instead of being an ARM-only version of a DSP+ARM SoC Jan 21 14:42:36 but yeah PRUwise the am6 is a monster Jan 21 14:44:31 although I think some earlier SoCs still win in terms of pru core count, but most of them were for special-purpose use (e.g. some ks2 SoCs had 15 pru cores in the Packet Accelerator subsystem and 8 in the Queue Manager Subsystem) Jan 21 14:47:11 zmatt: I don't know enough of the history of keystone to really grok what you're saying Jan 21 14:47:26 zmatt: I think keystone naming is getting blurry Jan 21 14:47:43 well the main thing I found funny is that architecture-wise the ks6 is clearly like TI's c6x DSP line of SoCs Jan 21 14:48:03 as opposed to am5 which is an omap5-derivative Jan 21 14:48:58 OMAP family and C6000/Keystone family SoCs look very different w.r.t. their overall architecture, especially interconnect and prcm Jan 21 14:49:07 zmatt: ah, ok, I'm only getting my feet wet with DSP side of things, my background is mostly omap Jan 21 14:49:21 zmatt: but I have some fun c667x work coming up this summer, hopefully :) Jan 21 14:50:01 so, the am6 basically feels like a DSPless DSP to me ;) Jan 21 14:50:01 "fun" Jan 21 14:50:14 zmatt: something like that, maybe it'll have a big brother :) Jan 21 14:50:32 just like the am1xxx SoCs, but those were just omap-L1xx SoCs with the DSP removed/disabled Jan 21 14:50:46 yeah maybe, but traditionally the DSP would have come first Jan 21 14:50:57 zmatt: I think DRA8 automotive needs might have driven a lot of the removal of the DSP from am6 to get to market Jan 21 14:51:50 interesting Jan 21 14:52:21 zmatt: Im' not in automotive but a lot of automotive things seem to be focused on super high powered DSP needs or more simple network hub things now Jan 21 14:52:31 I do like the C6x architecture, although I haven't really done anything with them for years Jan 21 14:52:49 yeah and the am6 isn't super high powered Jan 21 14:52:53 it doesn't have EVEs either right? Jan 21 14:52:57 don't think so Jan 21 14:53:06 DRA8 doesn't either, iirc Jan 21 14:53:34 yeah I meant the underlying SoC, not whatever part number marketing stuck to a feature subset ;) Jan 21 14:53:43 ah, well, yeah :) Jan 21 14:54:02 zmatt: don't worry, I'm sure TI will come out with something exciting soon Jan 21 14:54:20 that's why I prefer the names (e.g. subarctic and vayu) over part numbers... unfortunately I don't know the name of the dra8/am6, if it has one Jan 21 14:55:03 zmatt: only the cool kids know the internal names Jan 21 14:55:15 lol Jan 21 14:55:24 usually they are easy to find Jan 21 14:55:31 google is hard :) Jan 21 14:55:37 haven't really looked much in case of the am6 though Jan 21 14:57:28 it's funny how the am6/dra8 is in many ways the exact opposite of the tda3/dm50x/dra78x Jan 21 14:58:11 which has omap-like architecture, DSP and EVE, but no cortex-A/R Jan 21 14:58:32 and uses IPU as boot cpu :D Jan 21 14:59:16 zmatt: I've seen some neat radar integration things using those parts, IPU doing management and DSP doing number crunching Jan 21 14:59:33 with TI radars, obviously Jan 21 15:01:41 btw, do you happen to know why ATL (Audio Tracking Logic) is only in automotive parts, and pretty much undocumented? based on the limited info I have, it sounds like it would potentially have been quite useful in audio applications Jan 21 15:02:22 zmatt: dunno, I always thought that was for like FM/AM radio but I've not used the automotive parts Jan 21 15:02:59 basically it tracks the relationship between two clocks that have approximately the same frequency Jan 21 15:03:48 e.g. for asynchronous resampling or relating timestamps of two audio devices Jan 21 15:04:03 zmatt: oh, I dunno, maybe noise cancelling? Jan 21 15:04:35 no, nothing like that, it purely deals with clocks, not with audio data Jan 21 15:04:45 oh, dunno then Jan 21 15:05:09 basically, it seems very useful to me generically, which is why I don't understand why it seems to be kept so.. obscure Jan 21 15:06:06 the description even says " This same IP can also be used generically to track errors between two reference signals (such as frame syncs) and generate a modulated clock output (using software-controlled cycle stealing) which averages to some desired frequency." Jan 21 15:06:57 anyway, was just curious Jan 22 00:24:48 hi all ... when testing the dmp on BB-Blue, the yaw value slowly rotates when the beagle is not moving ... has anyone else seen this ? Jan 22 00:25:37 Man! You got that thing to fly? Good job. I am still in the process. Jan 22 00:26:29 i was able to stabilise the yaw value by enabling the magnetometer and Reading Magnetometer before ISR ... but it still seems wierd that that was required Jan 22 00:26:54 set_: :) ... it took quite a bit of experimenting Jan 22 00:27:12 I know. I am still trying but I keep getting interrupted. Jan 22 00:27:17 More tasks, more stuff. Jan 22 00:27:32 Good luck charlie5! Jan 22 00:27:35 More power to you. Jan 22 00:27:49 There is a chat about the BBBlue. Jan 22 00:27:52 trouble now is that if i quickly rotate the beagle 180 degrees, it takes about a minute for the yaw to increment to the new value Jan 22 00:28:01 Oh! Jan 22 00:28:05 set_: thanks :) Jan 22 00:28:15 where is the chat about BBBlue ? Jan 22 00:28:31 Hold. I stopped visiting. I need to find it again. Jan 22 00:28:33 Please hold. Jan 22 00:28:38 sure ... and thanks Jan 22 00:30:19 https://gitter.im/mirkix/BBBMINI is something I found where people discuss the BBBMini and pocketPilot/arduPilot on the BBBlue. Jan 22 00:30:27 Are you using ArduPilot? Jan 22 00:30:56 Or some other form of piloting software? Jan 22 00:31:38 i'm using the libroboticscontrol library Jan 22 00:31:43 Oh! Jan 22 00:31:45 Even better. Jan 22 00:31:50 This is the place. Jan 22 00:31:57 thanks for the link Jan 22 00:32:02 I am so sorry. I thought you were using ArduPilot. Jan 22 00:32:05 i'll ask there also Jan 22 00:32:09 Okay. Jan 22 00:32:45 charlie5: So, let me get a picture of what is happening before we get to yaw and that stuff. Jan 22 00:33:15 You used the librobotcontrol software to make a Quadcopter? Jan 22 00:33:24 Or copter/plane? Jan 22 00:34:00 nope, just an autonomous ground vehicle (for the moment) Jan 22 00:34:04 Oh! Jan 22 00:34:21 i have the edumip kit Jan 22 00:34:24 That is cool. I thought yaw was for angling in the air. Jan 22 00:34:25 Oh. Jan 22 00:34:38 yaw is compass heading Jan 22 00:34:43 That is it? Jan 22 00:34:54 charlie5: if it's just a gyro then I can imagine it's not strange if the value slowly drifts? Jan 22 00:35:03 pitch is elevation (rotation about the y axis) Jan 22 00:35:10 Oh. Jan 22 00:35:29 roll is rotation about the x-axis Jan 22 00:35:34 See, I learn stuff all the time. I never knew why it was so important to have those things installed and typed up to work. Jan 22 00:35:56 roll, pitch, yaw! Jan 22 00:35:57 charlie5: wait, bmp? you mean the mpu-9250 imu probably? Jan 22 00:36:02 the bmp is the barometer Jan 22 00:36:51 which, I assume, is not used for determining yaw ;) Jan 22 00:36:52 zmatt: the dmp rather than the bmp Jan 22 00:37:01 oh I misread Jan 22 00:37:04 what's the "dmp" ? Jan 22 00:37:17 digital motion processor, i think Jan 22 00:37:19 charlie5: There is also something to see here ---> https://www.hackster.io/edumip/edumip-13a29c Jan 22 00:37:25 I don't think I've seen that abbreviation before Jan 22 00:38:57 zmatt: I think mr. charlie5 got the acroynm incorrect. That is all. Jan 22 00:38:59 Right? Jan 22 00:39:25 If I could spell. That would have made sense. Jan 22 00:39:33 blah. Jan 22 00:39:38 set_: yep, that is the link we used to put the BBB/edumip together :) Jan 22 00:39:47 Oh. Jan 22 00:39:54 I'm assuming it means the imu... I just wasn't familiar with that particular name for it Jan 22 00:40:04 There is also some others. Please hold. Jan 22 00:40:11 People liked that kit when it first came out. Jan 22 00:40:56 ah, found the abbreviation in the imu's docs Jan 22 00:41:01 from the libroboticscontrol headers ... Jan 22 00:41:02 ##DMP Mode Jan 22 00:41:03 * Jan 22 00:41:03 * Stands for Digital Motion Processor which is a feature of the MPU9250. Jan 22 00:41:10 yeah, just found the same in the datasheet Jan 22 00:41:44 Hey. Are we talking BBBlue or BBB w/ Robotics Cape? Jan 22 00:41:46 okay, so that should be the fusion output that includes the magnetometer Jan 22 00:41:55 then it's odd that it drifts Jan 22 00:42:17 set_: BBBlue Jan 22 00:42:20 Okay. Jan 22 00:42:55 presumably the robotics cape uses the same imu? Jan 22 00:42:56 zmatt: yep, i thought it odd also ... was wondering if it is same for all ppl or something peculiar to my h/w Jan 22 00:43:13 do many ppl here use libroboticscontrol ? Jan 22 00:43:28 charlie5: I don't have a blue so I can offer only limited input I'm afraid Jan 22 00:43:34 I have only tested it a couple of times. Jan 22 00:43:44 I have a BBBlue, though. Jan 22 00:43:45 librobotcontrol you mean Jan 22 00:44:09 Yea. Jan 22 00:44:14 (formerly libroboticscape) Jan 22 00:44:24 yes, librobotcontrol, sorry Jan 22 00:44:36 librobotcontrol. Jan 22 00:44:41 Things change. Jan 22 00:44:45 I get the impression it's the main way to use the blue's functionality? Jan 22 00:44:55 i thought so too Jan 22 00:45:12 Heh? Jan 22 00:45:32 I thought you could use software, out of the "BLUE," for the BBBlue too. Jan 22 00:45:55 I did not think that we all had to use a set of software examples specified for the machine. Jan 22 00:46:43 But yea. librobotcontrol was specifically geared towards that board, BBBlue. Jan 22 00:47:24 i guess we don't if there are alternatives ... it's just that librobotcontrol came with the image we installed and seemed to be the main lib to use Jan 22 00:47:47 Yea. That does make sense. I used it. It works. Jan 22 00:47:54 the example code is also pretty nice Jan 22 00:48:13 you could try updating the lib if it's not uptodate already, or open an issue on github Jan 22 00:48:29 So, about this yaw? Oh and yes. The software has good examples for each component and what could be attached. Jan 22 00:48:40 So, there is nothing going on and it just moves? Jan 22 00:48:40 zmatt: yep, both good ideas Jan 22 00:49:20 yeah, the bot sits still and yaw slowly increments (about 1 degree every few seconds) Jan 22 00:49:44 That is odd. I wonder where in the software it says to move a little bit every so often. Jan 22 00:50:21 Like the stuff I typed up w/ help from 100,000 poeple does not do that but it is weak in relation to the librobotcontrol. Jan 22 00:50:34 charlie5: does the magnetometer maybe need calibration of some sort? Jan 22 00:50:37 possibly zmatt is right and the gyro is drifting Jan 22 00:50:56 zmatt is more correct more often on these subjects in relation to me. Jan 22 00:51:04 Most definitely. Jan 22 00:51:37 zmatt: it does and i calibrated it (as well as the accellerometer and gyro) Jan 22 00:51:46 ok Jan 22 00:52:13 I see you need a receiver and transmitter. Is this what you are using? Jan 22 00:52:41 nope, i think that is for the DSM Jan 22 00:53:19 "DSM2 and DSMX are common standards for remote control plane and car radios." Jan 22 00:53:38 in this case DSM is not involved Jan 22 00:54:29 https://github.com/StrawsonDesign/librobotcontrol is an example of their ideas. Jan 22 00:54:46 I keep coming up w/ psychiatric stuff when looking up DSM stuff. Yikes! Jan 22 00:55:12 Well... Jan 22 00:55:37 On that page, that github.com/Straw... page, there is a chat for their items they invented. Jan 22 00:55:48 librobotcontrol! Jan 22 00:56:16 Oh and if you need me to test something, let me know. Jan 22 00:56:26 I Have the bbblue in a stone's throw away. Jan 22 00:56:32 hmm I found some github post claiming the dmp only provides fusion of the accelerometer + gyro, not the magnetometer, but that directly contradicts the (not very detailed) datasheet Jan 22 00:56:54 set_: i'm using their own test program ... https://github.com/StrawsonDesign/librobotcontrol/blob/master/examples/src/rc_test_dmp.c Jan 22 00:57:27 did I break my bbb ? [ 43.403554] net eth0: phy "/ocp/interconnect@4a000000/segment@0/target-module@100000/ethernet@0/mdio@1000/ethernet-phy@0" not found on slave 0 Jan 22 00:57:40 what would cause that error ? a broken device tree ? or a real physical issue Jan 22 00:58:28 charlie: I am plugged in now. I will run the software soon. Should I plug in anything to test it? Jan 22 00:58:37 could be anything. since you're using a bleeding edge kernel I'd sooner guess a problem with that than with the hardware Jan 22 00:58:44 Motors, receiver, having a transmitter, and etc? Jan 22 00:58:47 but it worked before Jan 22 00:58:53 hmm Jan 22 00:58:53 it just did that all of a sudden Jan 22 00:58:56 after I carried it home Jan 22 00:59:22 consistently, even if you power cycle the board? Jan 22 00:59:32 it's rebooting to see that Jan 22 00:59:39 now it works, yeah Jan 22 00:59:42 set_: nothing else needs to be plugged in Jan 22 00:59:43 (note: power cycle, not merely reboot) Jan 22 00:59:45 but weird still Jan 22 00:59:46 yeah Jan 22 01:00:09 then I guess it's the phy issue the bbb has, and the workaround for it hasn't been forward-ported to the extremely bleeding-edge kernel you're using Jan 22 01:00:10 so maybe it's the 5.0.0-rc2 that could random issues like that Jan 22 01:00:16 ah Jan 22 01:00:17 charlie: So, I just plug in the BBBlue and run the software. Cha-bling, and it is supposed to work? Jan 22 01:00:24 so it's a known issue Jan 22 01:00:27 I see Jan 22 01:00:30 set_: yep Jan 22 01:00:36 Okay. Please hold. Jan 22 01:01:18 set_: $ rc_test_dmp -t Jan 22 01:01:23 charlie5: Where are those files located? Jan 22 01:01:42 yeah the reset timing of the phy isn't quite right, causing it to sometimes initialize in a wrong state. most commonly this causes the phy to be on a different address, which is what the workaround is for Jan 22 01:01:58 (more rarely it just doesn't work at all) Jan 22 01:02:02 set_: if librobotcontrol is installed they should be in your PATH Jan 22 01:02:22 /usr/bin/rc_test_dmp Jan 22 01:02:22 Okay. I will run that rc_test_dmp -t cmd. Jan 22 01:02:24 Please hold. Jan 22 01:02:29 cheers Jan 22 01:02:33 Cheers. Jan 22 01:03:05 brb Jan 22 01:03:14 charlie5: I got it. Jan 22 01:03:22 Let me pastebin.com it. Jan 22 01:04:21 https://pastebin.com/vCNuj2dT is some info. I found via that cmd. Enjoy! Jan 22 01:04:36 I have not fixed anything or calibrated anything. Jan 22 01:05:36 That is, as is. Jan 22 01:10:13 I bet we can find all kinds of info. from that bit of info. I displayed. Jan 22 01:10:16 set_: tah ... does the third value (yaw) slowly change Jan 22 01:10:27 Let me check again. Jan 22 01:10:29 Hold, please. Jan 22 01:10:54 The deg. keeps shrinking. Jan 22 01:11:06 Subtracting itself as we type. Jan 22 01:11:38 yep ... same behaviour as here Jan 22 01:11:50 behavior Jan 22 01:12:28 charlie5: So, that decrimental subtraction is yaw making moves w/out the "owner's" commands? Jan 22 01:12:57 $ rc_test_dmp -t -m -b ... the yaw value should eventually stabilise Jan 22 01:13:04 Okay. Please hold. Jan 22 01:13:26 set_: yes, changing w/o the bot actually rotating Jan 22 01:14:14 Oh. Can you cmd the bot to move w/out the lack of that cmd? Jan 22 01:14:47 can you use other cmds instead? Jan 22 01:15:09 Like forward, reverse, stop, go spasm, and etc... Jan 22 01:15:36 that command is only to test the DMP mode of the IMU Jan 22 01:16:05 Okay. So, w/ that test, you are "for sure" knowing what the IMU is giving as feedback? Jan 22 01:16:05 rc_balance will make the bot balance on two wheels Jan 22 01:16:12 Aw. Jan 22 01:17:26 yep, re IMU feedback Jan 22 01:18:18 i have written a program to make bot move forward/backward via remote control using mavlink Jan 22 01:18:30 Okay. charlie5: All my commands work but I can never test them b/c my kit is not here. I do not have one. Jan 22 01:18:32 Cool. Jan 22 01:18:51 I have not gotten into R/C yet w/ success. Jan 22 01:19:38 hok, thanks for the help guys ... i'll play around with it some more (maybe test the 'Normal' IMU mode and see what results that gives) Jan 22 01:20:11 I can keep testing things to let you know what is on my side of things, for future reference. Jan 22 01:20:29 thanks, that will be a help ! ... :) Jan 22 01:20:45 btw, are any of you blokes in .au ? Jan 22 01:21:09 (australia) Jan 22 01:21:27 Nope. Jan 22 01:21:29 USA! Jan 22 01:21:42 at this time, most of the rest of the world is asleep :D Jan 22 01:21:51 Oh. Jan 22 01:21:58 Southern Hemisphere? Jan 22 01:22:03 yep Jan 22 01:22:12 it's 12:22 pm here atm Jan 22 01:22:13 I know the toilet flushes in the opposite dir. there. Jan 22 01:22:17 Oh. Jan 22 01:22:17 lol Jan 22 01:22:21 ha! Jan 22 01:22:42 I used to live in WA. Jan 22 01:22:53 Bunbury! Jan 22 01:23:24 * charlie5 recalls simpsons episode with the US toilet flush machine to make the loo's here go in the 'correct' direction Jan 22 01:23:36 Ha. I missed that one. Jan 22 01:23:45 ah, right ... i've heard of Bunbury Jan 22 01:23:53 i'm in northern NSW Jan 22 01:24:05 Yes. They have Busselton, Bunbury, and Margeret River. Jan 22 01:24:09 Right on the Coast. Jan 22 01:24:15 nice Jan 22 01:24:19 Yep. Jan 22 01:24:30 i've not been further west than melbourne Jan 22 01:24:44 or further north than brisbane Jan 22 01:24:57 * charlie5 doesn't travel a lot :) Jan 22 01:25:01 Oh. It is nice out there. Hot, roomy, and full of water. Jan 22 01:25:02 Oh. Jan 22 01:25:12 mostly full of water. Jan 22 01:25:17 They have the beaches closed off. Jan 22 01:25:21 hot here also ... tho not as hot as WA, i guess Jan 22 01:25:29 Too many sharks. Jan 22 01:25:35 * charlie5 just had an air-con installed Jan 22 01:25:44 ...By you? Jan 22 01:25:48 yeah, i've heard the sharks are bad on the west coast Jan 22 01:26:01 nope, handyman did the install Jan 22 01:26:08 They have chains in the water so we could swim. Jan 22 01:26:32 Odd days. Jan 22 01:26:45 I'm not far from Byron Bay ... they have had a few fatal shark attacks over the years Jan 22 01:26:58 talks of putting in shark nets Jan 22 01:27:18 Yep. It sucks when water is around and no one can swim in it. Jan 22 01:27:23 * charlie5 nods Jan 22 01:27:35 I bet you can think of something to do w/ water and the BBB! Jan 22 01:27:45 BBB water vaporizer? Jan 22 01:27:49 mm, got to head off for a bit Jan 22 01:27:55 Okay. Jan 22 01:28:07 Good luck w/ Mavlink and the BBBlue. Jan 22 01:28:09 heh, a shark detecting/hunting BBB would be cool Jan 22 01:28:17 Yep. Or BBB tags. Jan 22 01:28:24 (BBB min-submarine) ... :D Jan 22 01:28:29 They have that! Jan 22 01:28:35 ah, nice Jan 22 01:28:42 I thought someone had an ROV interface for the BBB? Jan 22 01:28:51 I forget what it is called. ROV, that is it! Jan 22 01:28:57 Thank you, GenTooMan. Jan 22 01:29:14 I remember things just not well. Jan 22 01:29:24 hok, got to go ... cheers for the help and chat guys ... will talk more later Jan 22 01:29:36 Later mate. Jan 22 01:30:29 Let me see down under is 13 hours away? so it's 9:30am? Jan 22 01:30:45 Depending on which side. Right? Jan 22 01:30:52 or left ... Jan 22 01:31:01 I mean west really I do. Jan 22 01:31:14 Left 9:30, Right 15:05? Jan 22 01:32:01 GenTooMan: We were testing the BBBlue w/ librobotcontrol. Jan 22 01:32:10 it's not spaning the international date line and I think they don't go by half hour increments or 5:35 for that matter. But hey china is all the same time. Jan 22 01:32:23 I gave away my IMU info. Jan 22 01:32:32 Right. You flush it, we can scoop it! Jan 22 01:32:58 set_ and you successfully did something with it? Jan 22 01:33:07 w/ the BBBlue? Jan 22 01:33:09 Yep! Jan 22 01:33:25 Finally, a pride in the yaw. Jan 22 01:34:01 rich pull and yaw! Jan 22 01:34:08 Southern grin from cheeks to cheeks. Ooh. The librobotcontrol stuff works well. Jan 22 01:34:42 I was surprised that the librobot... kept up w/ info. and works as well as it does. Jan 22 01:34:47 It is really smart software. Jan 22 01:34:56 it helps when something works. Jan 22 01:35:01 Right-o. Jan 22 01:36:04 Hey. I know. GenTooMan: I was filling out this form from FirstBuild. Jan 22 01:36:17 They have this idea for a new, indoor smoker. Jan 22 01:36:24 I was going to help them w/ ideas. Jan 22 01:37:01 I would love to learn about that idea and get my BBB all up in that smoking smoker. Ribs, roasts, and rumps. Jan 22 01:37:25 ... Jan 22 01:38:05 huh. indoor smoker. Wonder how that'll work out. Jan 22 01:38:11 For now anyway. Their smoker is a bit small. I would enlarge the length of it for ribs most likely (instead of half racks). Jan 22 01:38:13 I know. Jan 22 01:38:17 It is interesting. Jan 22 01:38:42 Snert: Do you want to the link? Jan 22 01:38:50 sure I'll have a look Jan 22 01:38:56 Okay. Please hold. brb Jan 22 01:38:59 I suggest looking at existing smokers and determining how they are controlled temperature wise. Jan 22 01:40:05 https://firstbuild.com/blog/help-us-get-smokin/ Jan 22 01:40:31 They are in their first steps and trying to get feedback now. Jan 22 01:41:20 ... Jan 22 01:41:30 Hey. That must not be the one I am thinking about. Jan 22 01:41:43 These people just sent me an e-mail about it. I will see if I can dig it up. Jan 22 01:42:54 intersting though I can't figger out where the smoke leaves the house at. Jan 22 01:43:43 I understand. Jan 22 01:43:50 This is what grabbed my attention. Jan 22 01:44:01 I think something must lead to the outdoors. Jan 22 01:44:13 Hose, vac, something. Jan 22 01:44:21 I could see it sitting in a house window. Jan 22 01:44:50 I hope their ideas go w/ less expense compared to the other ideas. Jan 22 01:44:56 but dat greasy meat smoke needs to not collect on the outside of my house Jan 22 01:45:05 Right. Jan 22 01:45:25 I wonder. Hey, if you get the e-mail from them, take the survey. Jan 22 01:45:44 It shows a bit more of their ideas in the survey. Jan 22 01:46:31 I spose they don't wanna really give it all away by showing the whole idea on the splash page. Jan 22 01:47:38 the splash page shows a regular oven in use - prolly a test. Jan 22 01:48:05 I wonder if your oven ever smells not smoky ever again. Jan 22 01:48:19 Right. It is just a prototype. They are probably going to spruce it up to be that cost I was discussing earlier. Jan 22 01:48:37 In the survey, they asked what i thought of their dimensions. Jan 22 01:48:55 yea, they need to make some big bucks or else there's really no incentive. Jan 22 01:49:07 That is what I hate. Jan 22 01:49:25 Money, money, money. What about the experience? The humanity? Jan 22 01:49:46 Well, forget humanity. Just the experience. Jan 22 01:50:36 Snert: Do you think it is like a induction cooker and they had pellets and a screen for venting? Jan 22 01:51:14 I'm thinking wood chips in a bag you can buy Jan 22 01:51:25 but pellets might would work too Jan 22 01:51:36 Probably. Chips or pellets. Jan 22 01:52:21 Oh well. So, they have a hot plate, it heats the chips/pellets, and then their has to be some serious ventilation. Jan 22 01:53:19 I'm sure itzbeen tried b4. And there is prolly a reason there isn't a BigBrand Indoor Smoker out there. Jan 22 01:53:38 Oh well. Something interesting, for sure. Jan 22 01:53:39 Hahhaaha. Jan 22 01:53:40 Yep. Jan 22 01:53:52 I hope they do it. Jan 22 01:53:55 I want two. Jan 22 01:55:01 https://firstbuild.com/products/ventless-open-hearth-oven/ <--- I mean, they made this a reality. Jan 22 01:56:49 I like theor shop and their fristbuild community thing Jan 22 02:00:07 the ice balls are kind of neat Jan 22 02:01:25 That is cool. Ice balls. Jan 22 02:01:42 Literally. **** ENDING LOGGING AT Tue Jan 22 02:59:56 2019
