**** BEGIN LOGGING AT Sat Jun 01 02:59:57 2019 Jun 01 05:02:15 Should I use UART or GPIO for the RelayCape? Jun 01 05:03:11 I am asking b/c I posted on the Seeed-Studio forum. Jun 01 05:03:59 I was inquiring if their 30A grove adapter would work w/ the older version boards you all produced, i.e. BBGW. Jun 01 05:05:12 They only have uart or i2c connections on that board for grove adapters. Jun 01 05:05:48 <<<< never used a relay and yes it is true Jun 01 05:16:11 read more. I know! Jun 01 05:19:17 SPDT! Jun 01 08:03:07 set_: https://pastebin.com/G5JHb5fv Jun 01 09:05:55 Anyone used a ninja cape, all the websites and documentation seems to have died Jun 01 09:08:01 a what Jun 01 09:10:10 from what I can tell its an 433mhz tx and rx connected to an Atmel chip(Arduino like) and then sends received 433MHz codes in JSON over the UART Jun 01 09:20:01 sonuds like you have a fair bit figured out already at least :) Jun 01 09:49:46 The issue is the company went out of business and now all the websites are dead Jun 01 09:50:04 so the only info I have to work with are some strange things on google and all the code on github Jun 01 09:50:19 also using webarchive but it seems to have been designed as a cloud product Jun 01 10:09:31 The annoying thing is I have just moved and I can't find my arduinos to test on Jun 01 10:19:28 if it's UART, then it should be easy enough to test on the BBB directly Jun 01 10:21:38 I've given up Jun 01 10:21:47 going to use my cheap 433MHz reciever Jun 01 10:24:35 at least the hw docs seem to be online still => https://github.com/ninjablocks/hardware/tree/master/Ninja%20Blocks%201.2.1 Jun 01 10:25:19 maybe someone with eagle can make a pdf export Jun 01 10:54:47 zmatt: (reading what you were saying to Jonnyw2kk) why *is* there so much extra space in the images? i noticed that debian console image you referenced (bone-debian-9.8-console-armhf-2019-04-14-1gb.img) decompresses to… 891 MB. that makes it 60% empty! Jun 01 10:56:07 1) what's the right way to shrink an image? and 2) could that be done by the image-building scripts? Jun 01 10:56:49 because it's pretty much impossible to buy even 1GB cards nowadays Jun 01 10:57:11 also the images are DD's direct from a sd card/emmc chip Jun 01 10:57:28 tbr: ? Jun 01 10:57:47 and if the *file* itself is a concern, unpack as sparse or sparsify and use a filesystem that supports sparse files Jun 01 10:58:24 tbr: that wasn't what i had in mind, though that's another good reason to shrink Jun 01 10:58:25 dabbler: if the card you are putting it on is 8, 16, 32 or 256GB in size, then size of image doesn't really matter much Jun 01 10:58:38 tbr: it does for wear minimization Jun 01 10:59:05 no sense in dd-writing a bunch of empty space Jun 01 10:59:16 if you care about a few hundred megabytes of zeroes being written to your SD, then you have massive other problems Jun 01 10:59:28 also makes the flash process take longer Jun 01 10:59:58 and if you are constantly rewriting your cards, like in every few minutes, then you should strongly consider custom minimal images anyway Jun 01 11:00:01 people can end up writing images many, many times Jun 01 11:00:23 unless that's tens of thousands of times, it won't impact things, at all Jun 01 11:00:28 regardless of how trivial you think it is, if shrinking is also easy, why not do it? Jun 01 11:00:42 as it will introduce other problems Jun 01 11:00:48 such as? Jun 01 11:01:15 you need to know the size of the filesystem *before* you create it Jun 01 11:01:30 that's not always given Jun 01 11:01:58 and the benefit of trying to minimize a generic default image is just not there Jun 01 11:02:16 *if* you need this kind of optimization, then you should roll your own Jun 01 11:02:53 you can know the size of the filesystem if you've just created it in an image larger than you'd need Jun 01 11:03:14 then create an image of just the necessary size and copy Jun 01 11:03:18 related: I'd be pretty miffed if I'd flash my card and find out that there is ZERO usable space on it for a *default* image Jun 01 11:03:35 you expand it after flashing Jun 01 11:03:50 which the flasher script can do Jun 01 11:03:56 IIRC that's not part of the default behaviour Jun 01 11:04:27 that's why we're talking about this Jun 01 11:04:33 if you feel so strongly about this, I'd suggest to take the scripts, modify them, test it and send RCN patches Jun 01 11:05:00 he can suggest that, but if it's simple he might just do it Jun 01 11:06:32 now, my other question again. zmatt, how were you suggesting Jonnyw2kk shrink the image before flashing? Jun 01 11:09:27 I have no idea why they have so much free space instead of just making them min-size and auto-expand on first boot Jun 01 11:11:32 you're right. on first boot is a better idea than in the flasher script. Jun 01 11:12:07 would cover those who use SD as their system Jun 01 11:12:21 https://github.com/Drewsif/PiShrink Jun 01 11:12:23 I used that Jun 01 11:12:24 what i mentioned before about creating image of just the necessary size and copying contents would probably result in excessive fragmentation unless done by a binary that planned its work before beginning to copy any files Jun 01 11:12:44 the flasher script doesn't need to "expand" anything since it creates a filesystem of correct size on the eMMC to begin with Jun 01 11:13:29 you can just shrink the filesystem to minimum size with "resize2fs -M", shrink the partition, and truncate the image Jun 01 11:13:31 ohh then it copies its contents over with rsync? Jun 01 11:13:47 probably yeah, never looked at the script Jun 01 11:14:13 i remember seeing some mention of rsync when i happened to look at the display output during an unintended flashing haha Jun 01 11:14:28 I'd use rsync too so it makes sense Jun 01 11:15:02 how come? is the flashing process resumable if it's interrupted? Jun 01 11:15:22 i wouldn't think the copying itself would be more efficient than cp's Jun 01 11:15:35 rsync with appropriate flags is just the easiest way to ensure stuff gets copied correctly, including ACLs, sparse files, hardlinks, etc Jun 01 11:15:41 ah Jun 01 11:15:46 file capabilities Jun 01 11:15:56 gotcha Jun 01 11:23:36 rcn-ee[m]: what do you think of doing as zmatt described above to the images? (i.e. using "resize2fs -M" to shrink them before compression, then making them running "resize2fs" (no options) to make them fill the partition upon first boot) Jun 01 11:25:21 it would reduce flashing time and (for people who don't want to flash) allow the full space on the sd card it's flashed to be used without additional steps Jun 01 11:25:48 both are also important when flashing eMMC via BBBlfs/BeagleBoot Jun 01 11:49:51 it would also minimize wear to the SD card Jun 01 11:51:50 do you have in mind any particular method of determining when a boot is the first one, zmatt? Jun 01 12:12:06 https://pastebin.com/qFQb4NCq Jun 01 12:12:23 here's a script to shrink an image to min size Jun 01 12:14:38 I mean, just create the image with an empty "/expand-filesystem-on-next-boot" file, check for it in initramfs and remove it once it's done Jun 01 12:15:20 (or possibly early boot service, depending on how unhappy stuff gets if there's really little space) Jun 01 14:14:49 @zmatt: Thank you for the heads up on the GPIO pins on the RelayCape. Jun 01 14:15:16 I saw the schematic after finding other articles on relays. Jun 01 15:02:05 If anyone is using the datasheet for the Goodsky Relay on the RelayCape, please send some type of manual. I found IEEE's Datasheets360 but there is no article. It is just a page for the part number. Jun 01 15:02:06 ... Jun 01 15:02:07 Aw! Jun 01 15:03:57 I think I found something. Sorry for the panic. Here it is: https://datasheet.lcsc.com/szlcsc/GOODSKY-RWH-SH-105D_C157751.pdf. Jun 01 15:04:11 The photo is off but there are some ideas on its content. Jun 01 15:09:43 what are you trying to determine? Jun 01 15:11:02 Nothing right now. I just want to be able to determine when the times comes. Jun 01 15:11:30 I guess I was panicking over little info/math on my end. Jun 01 15:11:31 both mouser and digikey say the relays are max 15A @ 24V DC and max 12A @ 250V AC Jun 01 15:11:41 I saw that much. Jun 01 15:11:57 I am trying now to understand how to convert. Jun 01 15:12:16 ... to ? Jun 01 15:12:22 I am trying to convert VA and Watts to HP. Jun 01 15:12:38 I am coming up empty right now. Jun 01 15:12:47 So, back to the book. Jun 01 15:12:52 HP is not a unit used in electronics :P Jun 01 15:13:30 Right but at some point, motors have that amount of HP or at least 1/2 HP or 3/4 HP. Jun 01 15:13:40 it's a simple multiplier Jun 01 15:13:44 Oh. Jun 01 15:13:56 So. VA x W = HP? Jun 01 15:14:02 what? Jun 01 15:14:15 I do not know. Jun 01 15:14:18 Sorry. Jun 01 15:14:36 You stated multiplier. Jun 01 15:14:37 VA and W are the same thing (sort of, with some caveats) Jun 01 15:14:46 how about asking the web search engine of your least distrust: how to convert from watt to horsepower Jun 01 15:14:53 Okay. Jun 01 15:15:13 I have a wolfram alpha app. It can do the work for me. I want to learn how to do it. Jun 01 15:15:24 and what zmatt says regarding VA~=W Jun 01 15:15:33 wolfram should tell you the multiplier too Jun 01 15:15:33 tbr: I will look around again. Jun 01 15:15:35 Okay. Jun 01 15:15:38 just DO it Jun 01 15:15:41 1 hp is around 735-745 W depending on which of the various definitions of horsepower you use Jun 01 15:15:42 Okay. Jun 01 15:16:25 about 740. Got it. Jun 01 15:16:38 1 HP = about 740 W. Jun 01 15:17:02 of course an electrical motor that produces 1hp of mechanical power is going to consume more electrical power than that since motors are not 100% efficient Jun 01 15:17:29 (the efficiency will depend on many factors) Jun 01 15:17:50 I know. I have to give and take. @zmatt: how did you apply the math behind your conclusion? Jun 01 15:18:05 I didn't apply any math, I looked up the definition of horsepower on wikipedia Jun 01 15:18:09 Oh. Jun 01 15:18:12 Dang it. Jun 01 15:18:26 and it gave several, ranging from 735W to 745W Jun 01 15:19:01 I typed in the 740w into my computer thing on Wolfram Alpha. It says 0.992x HP. Jun 01 15:19:35 I would like to know how they did it, i.e. computational wise. Jun 01 15:19:40 Off to look it up! Jun 01 15:19:43 there is no computation involved Jun 01 15:19:49 None? Jun 01 15:19:52 it's just an arbitrary historical unit Jun 01 15:19:57 Oh. Okay. Jun 01 15:21:17 what do you expect? look at the name of it, it was literally a rough estimate of how much mechanical power a typical horse can deliver... Jun 01 15:22:06 I know. Jun 01 15:22:06 * tbr hugs the SI Jun 01 15:22:20 Horses are big and not a unit of measure. Jun 01 15:23:35 So, even though there are motors (not engines) w/ ratings of HP on them that are listed, I have to go on to think of it as P = E x I? Jun 01 15:23:53 wat? Jun 01 15:23:58 Yea. Jun 01 15:24:03 Power. Jun 01 15:24:16 define your varialbles Jun 01 15:24:32 Power = Voltage x Current? Jun 01 15:24:36 they're just different units for the same thing... like centimeters and inches Jun 01 15:24:46 (W and HP) Jun 01 15:24:50 Oh. Jun 01 15:24:52 Okay. Jun 01 15:24:59 So, I need to read about engineering instead on this one? Jun 01 15:25:04 and no it's not like P=UxI Jun 01 15:25:30 the required math to convert from Watt to HP is about 3 or 4th grade Jun 01 15:25:37 Oh. Jun 01 15:25:39 I have no idea what you need to read about since I have no idea what you're trying to do, ask, or what you're confused about apart from "everything" Jun 01 15:25:47 I am trying to remember. Give me a break. Jun 01 15:25:57 Okay. Jun 01 15:26:31 Power [Horsepower] = Power [Watt] * 0.75 Jun 01 15:26:40 So, I just wanted to make sure that the 15a @ 12vdc is for each switch/relay. Jun 01 15:26:42 for a simple approximation Jun 01 15:27:02 relays don't come in horsepower Jun 01 15:27:04 tbr: uhh no Jun 01 15:27:19 Yes! Convo! Jun 01 15:27:33 set_: it's per relay yes Jun 01 15:28:10 zmatt: right, went silently to kilo-watt Jun 01 15:28:18 I have a 14a, 24vdc motor. Jun 01 15:28:43 tbr: and it's the wrong way around, power in kW = 0.75 * power in HP Jun 01 15:29:16 ok, today I also fail at 3rd grade math :) Jun 01 15:29:23 set_: I wouldn't want to use a relay cape for motors, use motor drivers for that Jun 01 15:29:26 In series, how many relays should I use? Jun 01 15:29:30 Okay. Jun 01 15:29:51 No more relays for motors. I was reading about go karts. Jun 01 15:29:52 putting relays in series is completely nonsensical Jun 01 15:29:57 Okay. Jun 01 15:30:29 also depending on motor you might need to do more than simple ON/OFF Jun 01 15:30:46 Right. I would need the on/off/on. Jun 01 15:30:58 electric motors have pretty much full torque from standstill Jun 01 15:31:41 it's like having a car where the accelerator only has two positions 'none' and 'full tilt' and no clutch Jun 01 15:32:28 Right. I found a site that is owned by autodesk. Jun 01 15:32:37 Um...Instructables. Jun 01 15:33:15 Anyway, that site states that, from this writer or whomever, a list of connections to be made for the electronics. Jun 01 15:33:16 * tbr starts to question his involvement in this "discussion" Jun 01 15:33:23 Who? Jun 01 15:33:32 yeah I'm out too Jun 01 15:33:35 Fine. Jun 01 15:33:38 Sheesh. Jun 01 15:35:50 you probably can use 4 relays + 4 protection diodes to make an H-bridge I guess, but with these amount of power I'm not really feeling comfortable contributing further to this notion Jun 01 15:39:42 yes sir. Jun 01 15:39:46 Thank you, anyway. Jun 01 15:40:30 I found that info. but the controller for an H-bridge to handle my motor load is expensive. Ouch! Jun 01 15:41:51 there are some cheap 30A h-bridges around, but beware, they often have chinese clone drivers that can't handle the power Jun 01 15:42:20 ands don't forget to allow for the ground shift due to the load current or things will cook Jun 01 15:43:42 they're 12v only though so may be useless to you Jun 01 15:44:33 Right. I found a $185.00 controller that can handle 60a per motor at two motor output. Jun 01 15:44:46 That is too small for a cart. Jun 01 15:44:53 this one does 24 https://www.pololu.com/product/1451 Jun 01 15:45:26 and pololu will be OK. You might be able to find it cheaper. the vnh2sp30 is the 12V that's cloned badly Jun 01 15:45:37 Oh. Jun 01 15:46:46 I found the 2 x 60 sabertooth. This can interface w/ a BBB family board easily. It says 1000 lbs. general purpose. Jun 01 15:47:00 your $185 doesn't sound so bad when you consider it has spare capacity and runs 2 motors Jun 01 15:48:01 Right. I only need one motor w/ chain. Jun 01 15:48:19 BBB rat rod cart? Jun 01 15:50:03 Anyway, thank you for your input. I was going to use the BBB family of boards (SiP) for controlling my electronics. Small bots are fun and cheap at times. But...the ride is worth it. Jun 01 15:53:40 14a @ 24vdc motor w/ a 1275 rpm and 250w. I think I can tune it to set up at least 10 hours of deep cycle enjoyment. Jun 01 15:55:21 PWM! Jun 01 18:28:41 Hello Jun 01 18:35:01 I need to get started with BeagleBoard discussion forums? Jun 01 18:35:47 I posted a question but I don't see my question ? Jun 01 18:36:14 Do I need to create a username and password ? Jun 01 18:56:16 jani_: I think those forums work. Maybe you need to update Chrome? Jun 01 18:56:44 or...maybe you need a gmail account. Right? Jun 01 18:57:14 I doubt you need a gmail account to use a non-Google forum Jun 01 18:58:53 I thought the google groups forum was from gmail? Jun 01 18:59:01 Oh! Jun 01 18:59:04 On the website. Jun 01 18:59:13 dabbler: they're google groups Jun 01 18:59:19 you still don't need gmail Jun 01 18:59:22 Oh. Jun 01 18:59:26 Nice! Jun 01 18:59:43 I always wondered about that fact. Jun 01 18:59:44 maybe your first post needs to get moderated or something? to prevent spam Jun 01 18:59:53 Aw! That makes sense. Jun 01 19:00:16 I hate when forums don't say that, leaving you thinking something isn't working Jun 01 19:00:24 I'm just guessing Jun 01 19:00:27 Me too! Jun 01 19:00:56 I tried to answer some a while back. I never did get any replies. Jun 01 19:01:29 Someone was questioning the bone-debian-os. Jun 01 19:01:55 I said and I quote, "Update your eMMC!" Or maybe I said bootloader. Who knows? Jun 01 19:03:37 Is com always GND? Jun 01 19:04:06 "com" ? Jun 01 19:04:09 A bit more complicated most likely. Jun 01 19:04:40 Yes. COM. I saw on the schematic and in many more locations that some items have a COM terminal and it is usually GND. Jun 01 19:04:57 Like...w/ the schematic of the loadCape and RelayCape. Jun 01 19:05:18 Like a shared GND called COM or something? Jun 01 19:06:11 the relay COM pins are not connected to ground, they're just mislabeled Jun 01 19:06:12 Like in the GND for the MultiMeters. Jun 01 19:06:16 Oh. Jun 01 19:06:43 connecting the relay terminals to anything on the low-voltage side would pretty much defeat the purpose of using relays in the first place :P Jun 01 19:06:58 Aw! Jun 01 19:07:03 Good notion, sir. Jun 01 19:07:32 Relays equal high voltage use! Jun 01 19:07:47 well not necessarily Jun 01 19:07:52 oh? Jun 01 19:08:14 so, zmatt, returning to my write reliability Q: that's interesting about SLC mode increasing write performance. too bad it would at least halve capacity. (is the eMMC MLC or TLC?) the write reliability I was referring to in my Q though was the Write reliability setting register (WR_REL_SET). wondering the performance impact of switching to the mode that doesn't risk data loss (of whatever else happens to be in the same… erase block (i Jun 01 19:08:15 s it?) if power is interrupted during a write operation. Jun 01 19:08:17 Well, 115v and 46vdc is a good source. Jun 01 19:08:25 but the circuit being switched is isolated from the circuit that is controlling the switch Jun 01 19:08:36 Oh. NO and NC. Jun 01 19:09:10 dabbler: MLC, and yes I know what bit you're talking about and understood your question the first time Jun 01 19:09:49 as I said then, I don't know the impact of that bit in isolation, just in combination with SLC mode Jun 01 19:10:12 since this stuff is all one-time-programmable configuration, I didn't feel like testing a whole bunch of combinations :P Jun 01 19:11:04 oh, sorry. that's what i get for reading when tired, i guess Jun 01 19:11:42 once you switch to write reliability, you can't switch back?! Jun 01 19:14:27 worse, configuring that bit is part of the hardware partitioning setup, so setting that bit also requires making irrevocable decisions about other settings (e.g. SLC mode) Jun 01 19:15:28 (you set a bunch of settings, then set the PARTITION_SETTING_COMPLETED bit, then power-cycle the eMMC after which the settings become permanent and the eMMC will reconfigure and erase itself) Jun 01 19:16:18 Termination! Jun 01 19:16:19 da fuq!? Jun 01 19:16:42 why the hell would they make it work that way? Jun 01 19:17:06 let me guess: a penny cheaper? Jun 01 19:18:50 that eliminates my unexpressed wonder why you didn't just enable write reliability and SLC piecemeal to test the effect of at least one of them in isolation, though :p Jun 01 19:19:32 well some of those settings have a fundamental impact on how the eMMC manages its flash and can't reasonably be changed on the fly. this is obvious for SLC mode, but it could also be true for the write reliability setting in some implementations, I have no idea Jun 01 19:20:41 I think they expect this configuration is done as part of the manufacturing process of your device and changing it later is not a relevant use-case for the overwhelming majority of users (e.g. the millions of smartphones out there) Jun 01 19:21:19 this is just my guess though, I have not seen a motivation or rationale for this Jun 01 19:25:23 well i can certainly understand changes requiring restarts, and data loss in the case of SLC/MLC. *sigh* good point re phones, but they should have some respect for phone rooters! it's a good thing those sorts of assumptions aren't seen to fly with the firmwares of various PC components Jun 01 19:27:22 I have no idea what you mean by that last bit Jun 01 19:27:47 seen to fly = seen as acceptable Jun 01 19:28:02 that was not the confusing part Jun 01 19:28:41 imagine if hard disk manufacturers assumed you only needed to set the idle sleep time once Jun 01 19:28:59 this isn't mere idle sleep time Jun 01 19:30:49 no, but what's so functionally different between the write reliability mode and, say, the journaling mode of a file system? Jun 01 19:31:03 I do feel like it ought to be possible to reconfigure the eMMC again with loss of all data, especially since it already has to do so once. then again it is entirely possible that there's a good reason for it, I'm not privy to insight into the internals of eMMC devices Jun 01 19:33:11 I have no idea. that's my point, *I have no idea*. it's also not just a matter of whether it *could* be implemented, but whether it's worth the extra effort, complexity, cases/scenarios where stuff could go wrong, associated risks Jun 01 19:33:40 I agree it sucks though Jun 01 19:35:11 well i appreciate your thoughts. if only i could spare 1 GB of the eMMC :p Jun 01 19:36:02 yeah if you already have only 2G then sacrificing half of that is definitely not fun Jun 01 19:36:15 we also don't use SLC mode on our "development" beaglebone, just the production ones Jun 01 19:37:06 anyway, I'm afk Jun 01 19:37:13 @zmatt: Sir! Jun 01 19:37:19 afk in da house! Jun 01 19:37:27 sorry. Jun 01 19:37:31 lo Jun 01 19:37:35 *lol Jun 01 19:37:48 dabbler: I have jokes about the BBB too. Jun 01 19:37:59 oh dear Jun 01 19:38:01 What is black and read and painted all over? Jun 01 19:38:27 a BBB that fell in a bucket of red paint Jun 01 19:38:28 a BBB book from a painter! Jun 01 19:38:33 Ooh. Jun 01 19:38:41 Sorry. Okay. Jun 01 19:38:54 book? Jun 01 19:38:59 dabbler: What are you doing w/ your BBB lately? Jun 01 19:39:05 read! Jun 01 19:39:23 ahhh haha Jun 01 19:39:53 Sorry for my mild humor (nothing too strong). Jun 01 19:40:48 set_: no worries. i like humor. what i'm doing with it? first iteration of a home file, tor, media server. Jun 01 19:40:58 Aw. Jun 01 19:40:59 Okay. Jun 01 19:41:12 sounded earlier like you're doing robotics Jun 01 19:41:14 I never got into that but it sounds interesting. I remember reading some articles on tor. Jun 01 19:41:31 Yep. As usual. I plan on big things and end up settling. Jun 01 19:41:58 But. I invested some time to save money for a welding machine. Jun 01 19:42:09 I plan on putting in some small stick welds to some angle iron. Jun 01 19:42:32 I want to have my own cart managed by the BBB. Jun 01 19:44:00 If you want to see something funny. Look here: https://www.hackster.io/silver2row/an-app-to-control-your-roverbot-w-gps-dbe6a5. I made this w/ a linode serving Ubuntu. I can work my machine via internet now w/out the need for close controls. Jun 01 19:44:14 interesting. don't know much about welding myself Jun 01 19:44:18 Me neither. Jun 01 19:44:22 Books! Jun 01 19:44:29 haha but you're making a welding cart? Jun 01 19:44:32 Point and click basically. Jun 01 19:44:34 No. Jun 01 19:44:46 A cart to drive, w/ 24v of power! Jun 01 19:44:59 Some battery powered carts. Jun 01 19:45:14 ohhh Jun 01 19:45:32 remote control? Jun 01 19:45:47 Yep. I have been researching ideas. The motor controller says 1000lbs. Jun 01 19:45:48 No. Jun 01 19:45:55 Not remote control for this buggy. Jun 01 19:46:03 a go-kart? Jun 01 19:46:12 Basically. Rat Rod BBB! Jun 01 19:46:19 rat rod lol Jun 01 19:46:30 Yep. Just smaller. Jun 01 19:46:37 sounds fun Jun 01 19:46:53 One bucket seat instead of two. No foot pedals. One lever for glory and oomph. Jun 01 19:47:16 Like a dang boat on wheels. Jun 01 19:47:47 dabbler: Fun...yes. It will be years from now before I finish. If i ever. Jun 01 19:47:48 i understand the BB is better suited for that kind of application than mine Jun 01 19:47:54 Yep. Jun 01 19:49:10 Running tor as a server is risky for the bbb b/c of many computations. I mean, that is what computers are for right. But, not of this sub 1 GHz. Jun 01 19:49:21 my friend just happened to have one he wasn't using and i don't have the money right now to go buy what i guessed might work only to find out later it wasn't the right board. so i'm trying it out and seeing how far i can get before i become limited by its capabilities and noting which ones Jun 01 19:49:37 Oh. Jun 01 19:49:57 That is a great way to be introduced to something fascinating. Jun 01 19:50:03 great = good Jun 01 19:50:34 I gave up on my home server. I was using Ubuntu. I could not get the site out. It was only on my local puters. Jun 01 19:51:18 i thought the BBB was 1 GHz. fortunately it does have the AES instruction set in the processor. not the same as a hardware unit, i know. will probably look for that in my next system Jun 01 19:51:19 I got scared w/ the ftp sites. It bugged me out that it was for people installing directly from my source. Jun 01 19:51:45 dabbler: They have another one coming out. Jun 01 19:51:52 At some point. Jun 01 19:52:08 AI. A bit of a new processor and w/ cool gizmos. Jun 01 19:52:52 EVE, M4, PRU, and maybe some WiFi. Who knows? Jun 01 19:53:30 for a system i want to be able to serve files, torrent, run a tor node, and decode video to my TV, i suspect the whole beagle line just isn't going to be my best choice, even with improved processors Jun 01 19:53:48 all those things potentially simultaneously at times Jun 01 19:54:08 Oh. Jun 01 19:54:13 so more cores, gigabit ethernet, and USB 3 will be pretty important Jun 01 19:54:22 also more RAM Jun 01 19:54:41 I guess. What would you use instead. A full blown 'puter? Jun 01 19:55:05 Like an old refurb. desktop? Jun 01 19:55:30 yeah, i do wonder if i should instead be looking for a new used macbook and repurpose this one, a Pro Jun 01 19:55:52 don't really have the money for that, though Jun 01 19:55:55 I know Dell has refurb. deals. Hell, businesses just chunk ' Jun 01 19:55:58 em out at times. Jun 01 19:56:22 They just toss them in the trash instead of repurpose them. Jun 01 19:56:53 dabbler: If you have "guts" or connections, contact a local industrial park business for this type of refurb. Jun 01 19:57:29 since this is a machine that would be running 24/7/365, i like the reduced power usage of an SBC Jun 01 19:57:36 Oh. Jun 01 19:57:39 Good point. Jun 01 19:57:51 not sure whether it would still have much less power consumption if it had all the capabilities i want though hahaha Jun 01 19:58:37 Right. The BBB, to me anyways, is a good board. It has helped me learn multiple ways to anger myself. Instead of just plain, ole anger, I learn too. Jun 01 19:58:51 haha Jun 01 19:59:19 I could not explain most things that are relative to programming (still cannot) but now I have a firm grasp on connections, ideas, and circulation of ideas involving electronics. Jun 01 19:59:20 ... Jun 01 19:59:33 There were many books produced a while back for the BBB. Jun 01 19:59:51 They were all, in the writer's own right, interesting. Jun 01 20:00:08 I believe this is where I first read about tor. Jun 01 20:00:12 In some book years back. Jun 01 20:01:21 rcn-ee[m] pointed out a brand of mini-comps called Qotom. not sure whether even they would be sufficient to handle everything i listed Jun 01 20:01:53 Think. You will need to get software for computing/seeing the use of your server. Jun 01 20:02:15 Like, how much i/o, how much traffic, and so on. Jun 01 20:03:03 If you plan on using a server for fun, it can work. I even found a couple good debian/ubuntu sites w/ this info. Jun 01 20:03:51 yeah, i wish i knew of a wizard for estimating those based on what set of tasks you want the system to perform Jun 01 20:04:19 i have a feeling just my torrent client would be too much for the little BBB Jun 01 20:04:30 https://www.ubuntu.com/community and then go to ubuntu server. Jun 01 20:04:50 Ubuntu server is small in comparison to the full-fledged distro. Jun 01 20:05:26 There is this one guide. Please hold. I will see if I can find it again. Jun 01 20:06:13 yeah, i've always used ubuntu in the past, but to provide more living space on the BBB i switched to debian Jun 01 20:08:23 Oh. Jun 01 20:09:00 I cannot find the dang info. on the server. But, I did find this idea: https://www.ubuntu.com/download/server/arm. Maybe not for the BBB but for some other form factors. Jun 01 20:10:28 https://help.ubuntu.com/lts/serverguide/index.html <<<< found it Jun 01 20:10:54 This will provide some ideas on your visuals needed to monitor your server. Jun 01 20:19:49 well that seems to cover relevant software packages for different tasks. it's the hardware i'm unsure about Jun 01 20:20:19 https://wiki.ubuntu.com/ARM/Server/Install?_ga=2.90733405.635068259.1559420276-1126794279.1556237763. Jun 01 20:20:34 That site has outdated info. and some up-to-date info. too. Jun 01 20:22:04 Everything seems outdated, actually. Sheesh. Jun 01 20:22:24 those are ubuntu installation instructions for different hardware. i need something about selecting the right hardware Jun 01 20:22:33 Oh. Jun 01 20:22:43 Hmm. Good question. Jun 01 20:22:51 I guess...um. Jun 01 20:23:11 Do it w/ a larger than average GHz rating. That may help. Jun 01 20:23:38 and estimating the total loads (CPU, RAM, I/O throughput, etc.) of different combinations of uses Jun 01 20:24:09 I mean. Think about it, right. Servers need to be backed up, have raid, and so on. I mean if it fails, what is the back up to that failure, right. Jun 01 20:24:24 The server just then dies? Jun 01 20:24:40 Nope, you need a network and not just one source for distribution. Jun 01 20:25:56 dabbler: Let me look around. I found some odd boards here and there w/ older distros b/c of their usage but it may be viable for tor and a server. Jun 01 20:26:44 I think you can stack four BBBs together to make a mesh. Jun 01 20:26:53 Let me see. Jun 01 20:28:44 i don't need enterprise reliability here. i was thinking i'd do periodic cloud backups (something like backblaze) of my data, so i don't think i need the redundancy of RAID. and i won't have the I/O demand to require its other capabilities. i think USB 3 connections to backed up external disks will be sufficient Jun 01 20:29:17 Is USB 3 actually called USB C? Jun 01 20:29:23 Oh. Jun 01 20:29:28 Oh. Jun 01 20:30:03 http://www.ti.com/lit/ug/tidude6/tidude6.pdf has been in it a bit. Jun 01 20:30:21 They produce many ideas on this topic, circa 2015. Jun 01 20:30:47 I will look to an old book for tor examples. Jun 01 20:30:48 Please hold. Jun 01 20:33:17 http://www.ti.com/tool/beaglebk and "beaglebone for secret agents, (Datko 2014)." Jun 01 20:33:43 Page 48 of that book is the Tor Bridge for the BBB. Jun 01 20:41:12 thanks. :) appreciate your efforts, but i need to get some housework done now. ttyl Jun 01 20:42:41 peace. Jun 02 01:22:01 I see we have some nice, new colors on our terminals when typing up source. Jun 02 01:22:03 Nice! Jun 02 01:41:38 Hello. Should I look to this info, https://linux-kernel-labs.github.io/master/labs/device_drivers.html, for setting up GPIO on the BBB w/ kernel 4.19.x? Jun 02 01:42:19 I am asking b/c I feel still newly born in this hemisphere. Send guidance! Jun 02 01:54:38 How should I go about using commands in the newly refurbished kernel w/ character device? Jun 02 01:55:32 I tried to print out my ls -la command to specific "character devices." Jun 02 01:55:34 No go. Jun 02 02:30:19 Can I just type this out until I feel niceness surrounding me? Jun 02 02:30:23 character device! Jun 02 02:31:52 Okay. That was it. Jun 02 02:35:29 What config do we use in the debian OS for the BBB? Jun 02 02:44:06 Scratch that last bit. **** ENDING LOGGING AT Sun Jun 02 02:59:58 2019
