**** BEGIN LOGGING AT Tue Mar 23 02:59:56 2021 Mar 23 03:06:24 10:00! Mar 23 14:31:29 wow i just expierenced one of the biggest set backs in coding for a long time ... yesterday i had it working like a charm but for the wrong reason and now i cant get it back Mar 23 19:01:51 Running Debian 10... lots of networking issues. I've set a static IP and I'm connected to LAN via ethernet and BBB accessible by other devices on LAN no problem. But internet access keeps failing. When I `systemctl restart networking` I'll be able to ping 8.8.8.8 for like a minute and then it fails again but still accessible on LAN Mar 23 20:12:24 GenTooMan: I got the pick up and wires attached and in their respective places and almost ready for BELA. Mar 23 20:12:50 I still need to mark up some grooves for the strings so they stay in place. Please hold for photo. Mar 23 20:13:35 * GenTooMan sings the song "Life On Hold, press 1 to repeat" Mar 23 20:13:51 https://drive.google.com/file/d/1snWZVVS5dsoxF7dGGBjdpMDYRgN-4p4I/view?usp=sharing Mar 23 20:13:58 Repeat that, sir! Mar 23 20:14:02 Neat heh? Mar 23 20:18:38 It appears you covered it with some fibre glass type material? Mar 23 20:18:57 No...that is from sanding. Mar 23 20:19:08 I put a truss rod in it too. Mar 23 20:19:51 The damn pick up was giving me trouble. I must have made 15 holes in it so far and that was 15 holes just for the pick up. Mar 23 20:20:16 hmm are you making a guitar> Mar 23 20:20:22 Luckily, I had a 3/64 bit for the strings. I missed those holes too. Blah. Mar 23 20:20:23 No. Mar 23 20:20:25 Violin! Mar 23 20:20:33 Electric Violin! Mar 23 20:20:59 I am waiting on the machine tuners now. I found some machine tuners that I think may work. Mar 23 20:21:32 ukulele tuners but they should do! Mar 23 20:22:37 It is hard wired now. So, I got an old amp, BBB + BELA, and the elect. violin to do stuff w/ at the Maker Faire. Mar 23 20:22:40 Phew. Mar 23 20:23:24 are you using the frequency of vibration to convert the string to a midi note then set up the timing etc based on that? Mar 23 20:23:35 I could have only hoped I got farther down the line in their documentation and chapters. I am only on chapter 6. Mar 23 20:23:42 Yes. Mar 23 20:23:52 I can...see. Mar 23 20:24:25 I was going to do a plug and play version. I plug it in and then I play. But...I have only gotten so far w/ the BELA tuts. Mar 23 20:25:09 So, I do not have all the required instruction so far to handle all their ideas that are reality in C++ on the BBB/BELA for the show. Mar 23 20:27:06 GenTooMan: The last BELA tutorial I got to was tut. six. So, in that tutorial, they had a GUI and some source. In the GUI/source, one could alter the sound of the output w/ either the GUI, source, both, neither, and/or an instrument. Hence...electric violin! Mar 23 20:28:54 Maker Faire was not going to be this year. So, they just contacted me and said it is on the 10th of April. I have not planning time. I have nothing but older projects that need revamping and some newer projects that need an entire new world. Mar 23 20:29:24 -- Mar 23 20:29:45 I recommend only show what you accomplished. So the uneven finish is do to roughing the outside of the violin structure. Normally one would put a sealer / primer one after the rough finish is cleaned then proceed toward 1200 or 1600 grit so it is fairly polished then put protect coat(s) on it. Mar 23 20:30:35 Okay. You think it will sound like dung? Mar 23 20:30:56 It is my first and only so far. I would be happy if dung sung. Mar 23 20:31:39 not sure I was just talking esthetic appearances only. If you don't care about it, just said you were trying to make it look like wood grain. :D Mar 23 20:31:39 I am not a fiddler. really. I am not. But...I can be. So, I will just show it and hope a fiddler shows up to play it. Mar 23 20:31:50 Ha. Mar 23 20:32:25 if you coat it correctly it might actually do that. Mar 23 20:32:31 if you're not a fiddler, how come you're always fiddling around with something? Mar 23 20:32:46 I fiddle w/ no fiddle. Mar 23 20:33:11 actually a friend of mine is a violin collector and fiddler his daughter is a concert violinist I guess he got interested in it because of her. Mar 23 20:33:26 This time, a rare occurance, fiddling w/ a fiddle is due. Mar 23 20:33:28 Oh. Mar 23 20:33:54 Nice. Concert! Big skill set that... Mar 23 20:34:09 it takes decades of practice. Mar 23 20:35:05 I know. I understand. I watched this fellow play a violin/fiddle on youtube. I was blown away. He was an older gentleman that knew his way around the unfretted fiddles. Mar 23 20:35:11 It was awesome to watch. Mar 23 20:36:08 Well, w/out my machine tuners, I am really blowing smoke here. So, until another day. I will show it again soon, before the Faire, in case the Faire people demolish my fiddle. Mar 23 20:36:25 most violins are unfretted. I think the scariest violinist to deal with is one who plays purely by ear. The reason that is, due to the number of times they need to practice a whole concerto before it doesn't drive your ears crazy. Mar 23 20:36:46 * GenTooMan has run concerts so... heh. Mar 23 20:37:17 doodle, doodle, doo * 9e10 Mar 23 20:37:54 Oh... Mar 23 20:38:25 GenTooMan: I had the incorrect cables for my machine I was building. So, the motor and cross-comp. w/ the BBB will take some more time. Mar 23 20:38:38 I think you can work with the finish of your violin to be fair. I would think a slow setting epoxy coating would do the trick. then you carefully polish it. The underlying undulations of the printing you can use with care to make it look like wood grain. Mar 23 20:38:39 This motor is bad! Mar 23 20:38:59 I do not have that time. Mar 23 20:39:02 oh it doesn't function? Mar 23 20:39:06 the 10th... Mar 23 20:39:16 Well yeah. Mar 23 20:39:17 I need to practice, gather, and organize. Mar 23 20:39:24 It works. Mar 23 20:39:33 I just have to plug it in. Mar 23 20:40:23 Right now, w/out machine tuners, I have no way to test. I need to tune the machine, plug it in, and wonder. Mar 23 20:40:43 Hmm, "How about I rosin up my bow? Mar 23 20:40:56 do you have a bow? Mar 23 20:41:00 yes! Mar 23 20:41:26 I got a cheap-o, depot bow. It was so cheap, I am scared to rosin it up. Mar 23 20:41:50 I am afraid that what they call horse hair is synthetic fibers. Mar 23 20:42:37 if you want inexpensive to order audio stuff https://www.parts-express.com/ I can't guarantee the quality. Mar 23 20:42:45 Ha. Okay. Mar 23 20:42:47 Thank you. Mar 23 20:43:18 I usually get all the motors and things second hand. They have a place called Surplus Center. Mar 23 20:43:34 People just dump what they did not use at this place. Mar 23 20:43:39 well for example if you want to make some speaker panels for the house they have transducers that can drive foam board and the like. Mar 23 20:43:40 They sell it. Mar 23 20:43:49 really hmm URL? Mar 23 20:43:53 Wait. Mar 23 20:43:55 Let me get it. Mar 23 20:44:08 * GenTooMan sees set_ is "well" prepared. Mar 23 20:44:52 Where can you get a hydraulic motor for under $200.00? https://www.surpluscenter.com/ Mar 23 20:45:54 Pumping that oil mate! Mar 23 20:45:59 Air too! Mar 23 20:49:50 I was looking at 545mm speakers for sub woofers hence parts express. Mar 23 20:50:41 Oh. Mar 23 20:50:48 Are you building a system? Mar 23 20:52:55 The cabinet for those will be kind of big. I was thinking about it. However I feel 2KW RMS power seems dubious likely they are only 1KW. They aren't dual voice coil either. Very disappointing. You use dual voice coal to use multiple amplifiers in parallel to reduce current issues. Mar 23 20:53:40 Nice. Mar 23 20:55:09 I just want to go through the design process. Since midrange and tweeters would be handling most of the power subs are just filler. Mar 23 20:55:30 Double nice. Mar 23 20:55:49 however you don't want to put that in your car, unless you want to spray glass then well it's up to you. Mar 23 20:56:00 I picked up a book on analog stuff a while back. It gets into digital stuff too but... Mar 23 20:56:44 good digital isn't all that complicated analogue is what digital is. Digital is just over simplified analogue. Mar 23 20:56:46 I am only on chp. 6. I get getting back tracked on it. It discusses amplifiers, reducers, and basics. Mar 23 20:57:07 Let me see... Mar 23 20:57:39 right I need a quasi complimentary symmetry class AB amplifier. :D Mar 23 20:58:26 Okay. Hold for quasi. The rest. Who knows? Mar 23 20:59:06 right let me explain it in terms you can understand then. Mar 23 20:59:57 ARRL, Inc. is the people who typed it up. Mar 23 20:59:59 complimentary symmetry means a bridged amplifier with the load between 2 half bridges. quasi means you use the same transistor type for upper and lower drivers. Mar 23 21:00:10 Oh. Mar 23 21:00:13 Thank you. Mar 23 21:00:44 GenTooMan: "digital" means highly non-linear analog ;) Mar 23 21:00:51 I may never learn that entirely but that is good info. Mar 23 21:01:45 The reason for that is finding transistors that are matched is very difficult PNP / NPN hence you use 2 of the same type NPN power transistors for the high and low side drivers. Mar 23 21:02:38 zmatt, heh :D Mar 23 21:04:07 set_, https://falstad.com/circuit/ <-- over simplified circuit simulation. Mar 23 21:05:54 GenTooMan: we once made some prototypes of a nice little sub... and by little I mean you needed two people to lift it ;) Mar 23 21:07:16 boom, boom! Mar 23 21:08:56 zmatt considering the driver might weight 25kg then add in the mass of the cabinet and other stuff I can see that lifting an 85kg cabinet might need more than one person. :D Mar 23 21:10:00 I always see the sign: "Use two people to lift!" Mar 23 21:10:06 now, I know why. Mar 23 21:10:50 you should see the connectors for those things, they are bigger than your hand and the cables make your fingers look like spaghetti. Mar 23 21:11:16 GenTooMan: and I don't remember if it was a sub or a main unit, but I remember some trial customers used it at such high power that a driver demagnetized from the heat, and I also remember some cabling having melted through acoustic dampening material Mar 23 21:12:33 it was pretty wtf Mar 23 21:14:54 that's not as uncommon as one would want, it's expensive frying those things. They probably used the NEC to get the cable size. Normally that would be OK but not with MTW wire Mar 23 21:15:32 I have no idea what that means. note that these were active units, integrated amplifier Mar 23 21:15:55 Really that's messed up. Mar 23 21:16:24 probably the connections couldn't handle the current then. Mar 23 21:16:51 iirc we relaxed some of the limiting because people felt they couldn't go loud enough :P Mar 23 21:17:20 maybe it was relaxed a bit too much Mar 23 21:17:25 I dunno, it was a long time ago Mar 23 21:17:39 that is kind of funny. Mar 23 21:18:35 I also remember a photo with some DJ having a set of us... as monitors, behind him, pointed right at him Mar 23 21:18:46 do these people not have any functioning hearing left? Mar 23 21:20:23 probably not. I remember having to deal with a deaf choir director once. It was ... nuts. Mar 23 21:21:18 the guy complained "we need people that can handle pain" then a minute later he goes "dang my deafness is such a hassle at times" <-- duh? Mar 23 21:32:44 Okay. I am going to make a makeshift setup on the BBB/BELA w/ the Violin. Wait for glory (or failure)! Mar 23 21:43:31 glorious failure! Mar 23 21:44:09 Yep. I failed. I am going to need the machine tuners. The wires/strings are too unruly. Mar 23 21:44:21 I cannot tie 'em down easily enough. Mar 23 21:44:39 But...I am plugged in! Mar 23 21:44:45 No errors so far. Mar 23 21:46:16 I am using the wavetable controller right now. I need to figure out input on this C++ source first. 14 days! Two weeks! A Fortnight! Mar 23 21:47:52 hmm so if you work 16 hour days for 14 days that comes out to be 224 hours of time. Mar 23 21:48:25 the equivalent of 4.5 weeks normally, think you can do it in a month? :D Mar 23 21:48:40 So, I will spend about two hours of the 14 days working on this project. Argh! Mar 23 21:48:51 I will get it! I will! Mar 23 21:49:00 But no...I do not think I can doo-ee. Mar 23 21:49:13 I will try... Mar 23 21:49:25 how about 2 hours per day 10 days that's 20 hours if you are careful and meticulous you can do it. Mar 23 21:49:48 Good idea. Two hours a day. I can doo-ee! Mar 23 21:51:47 right just remember do the work first then play. Mar 23 21:57:59 Play then work. Got it! Mar 23 22:12:09 so far on my pocketbeagle most of the examples fail. also the pru cookbaook including case studies likewise. basic on /off is ok. ntp, bluetooth, neopixel all fail Mar 23 22:14:54 most examples are probably for the beaglebone black I guess? bluetooth would presumably be for the beaglebone black wireless (since neither beaglebone black nor pocketbeagle has bluetooth) Mar 23 22:15:34 I've never looked at the examples myself really, so I wouldn't know :P Mar 23 22:19:50 but yeah I agree that a set of basic examples shipped with the image ought to work, this doesn't sound like a great out-of-the-box experience Mar 23 22:21:18 going for the 2017 image as a other user said it worked till then and not since Mar 23 22:21:38 that sounds like a terrible idea Mar 23 22:22:19 its that or the bin. I cant use it for projects without neopixel at least Mar 23 22:23:15 with neopixel you mean ledscape? Mar 23 22:23:47 I don't see why that wouldn't still work, as long as you change it from remoteproc-pru to uio-pruss (you can do so in /boot/uEnv.txt) Mar 23 22:24:12 Try...w/ python3 updates. SOme of the old examples are still in python. Mar 23 22:24:33 like, whatever causes some example to break on the latest image, it's probably something minor and fixable Mar 23 22:24:38 I cloned it and am starting to make headway on the examples. Mar 23 22:24:42 change it from remoteproc-pru to uio-pruss (you can do so in /boot/uEnv.txt sounds good Mar 23 22:26:14 wizard3141: there are three uboot_overlay_pru= lines in /boot/uEnv.txt, two of which commented out. the default one on the latest image will be uboot_overlay_pru=/lib/firmware/AM335X-PRU-RPROC-4-19-TI-00A0.dtbo but you can just comment that one out and uncomment uboot_overlay_pru=/lib/firmware/AM335X-PRU-UIO-00A0.dtbo Mar 23 22:26:30 syntax? Mar 23 22:26:40 ? Mar 23 22:31:12 fantastic. will do Mar 23 22:35:33 back to play time. ttfn Mar 23 23:55:44 looking for advice on my networking troubles: Mar 23 23:55:45 (fully working) ubuntu PC: Mar 23 23:55:45 `ip route show` Mar 23 23:55:46 `default via 192.168.101.1 dev enx00e04c680a42 proto static metric 100` Mar 23 23:55:46 (working LAN but not internet) debian 10 console BBB: Mar 23 23:55:46 `ip route show` Mar 23 23:55:47 `default dev eth0 scope link` Mar 23 23:55:47 `default via 192.168.101.1 dev eth0 onlink` Mar 23 23:56:58 ``` Mar 23 23:56:59 multiline comments Mar 23 23:56:59 would be better Mar 23 23:56:59 ``` Mar 23 23:57:02 darn Mar 24 00:09:48 masdf: please don't pate multi-line stuff into IRC, use a paste service like pastebin.com Mar 24 00:09:57 *paste Mar 24 00:10:12 yeah it's atrocious, sorry about that Mar 24 00:10:22 and dunno, normally if you plug a beaglebone into an ethernet network it should just work fine Mar 24 00:10:28 I've never had problems with it Mar 24 00:10:55 "default dev eth0 scope link" looks wrong though Mar 24 00:11:21 I don't think that should be there (and it isn't there on my BBB) Mar 24 00:15:57 Its one of the few discrepancies that stands out to me but I'm not sure what causes it Mar 24 00:16:29 did you change any network settings or just plugged it in? Mar 24 00:20:51 my network settings in `/etc/network/interfaces`: Mar 24 00:20:54 https://pastebin.com/SG8Cxj3S Mar 24 00:22:40 using two network managers at the same time is what's causing your problems... the default images all use connman (configured using connmanctl) so if you're using ifupdown (configured via /etc/network/interfaces) at the same time, they'll be fighting each other Mar 24 00:23:09 why are you using static configuration? Mar 24 00:23:13 are you saying I've been con'd Mar 24 00:23:34 my lab network requires static IPs for hardware targets Mar 24 00:24:00 how odd Mar 24 00:24:43 anyway, I'm sure you can configure a static IP for eth0 via connmanctl; alternatively if you want to you could probably disable connman entirely and use ifupdown instead Mar 24 00:25:00 (I personally use neither, I replace them with systemd-networkd) Mar 24 00:26:20 How would you recommend addressing for hardware targets in a lab setting where they need to be accessed remotely. Wouldn't you have difficulty if their IPs were changing dynamically? Mar 24 00:26:32 no, I connect by hostname Mar 24 00:27:04 hostname.local specifically Mar 24 00:28:06 oh I see, I guess that's a reasonable way to do it Mar 24 00:28:21 and thanks for the tips...  I'll investigate what conman is up to Mar 24 00:28:22 and in the rare case that I do want a device to have a fixed IP address, I statically assign it in the router dhcp server so that that device always gets assigned that address, without having to change the device's configuration Mar 24 00:28:51 that way I don't lose the ability to just pick up the device and plug it into any random network and have it work Mar 24 00:28:59 spoken like someone who understands networking haha Mar 24 00:29:01 I'll get there Mar 24 00:29:36 but honestly I don't generally have any reason for a fixed IP address, hostnames are fine Mar 24 00:31:03 okay in my defense the debian networking guides I've been using don't even mention connman: https://wiki.debian.org/NetworkConfiguration Mar 24 00:31:17 where should I have been looking? Mar 24 00:31:26 yeah those refer to vanilla debian Mar 24 00:31:44 connman being installed by default is specific to the beagleboard.org images Mar 24 00:32:11 I think the default /etc/network/interfaces contains comments intended to explain to people where they're supposed to be instead? Mar 24 00:32:14 iirc Mar 24 00:32:59 yeah it has a "connman: ethX static config" remark Mar 24 00:38:54 you know your stuff zmatt, this definitely looks like a connman conflict Mar 24 00:40:15 var/lib/connman/ethernet_blahblah_cable/settings is set to auto: https://pastebin.com/BYpqveES Mar 24 00:40:49 note that I don't think you should edit /var/lib/connman/ manually, use connmanctl Mar 24 00:50:14 will do, thanks for the help mate! Mar 24 01:00:32 Hey! Mar 24 01:00:58 connmanctl does not work any longer? Can anyone get that to work w/ the image from bbb.io/latest-images? Mar 24 01:02:09 https://pastebin.com/wG10Rsvm is a bunch of ideas that do not work... Mar 24 01:05:15 Someone stole my BBB sd card! Mar 24 01:05:19 I have to get ready. Mar 24 01:05:23 Ha. Mar 24 01:05:27 Dang people. Mar 24 01:09:13 Well, someone stole my sd card. The board is okay now! Mar 24 01:11:38 Man. At least dollar per GB went down. **** ENDING LOGGING AT Wed Mar 24 02:59:57 2021
