| 12:12 | topi` | mwcampbell: all HB carriers except the Gate have a headphone jack |
| 12:12 | topi` | at least my Gate doesn't have one |
| 14:45 | mwcampbell | I read that the HummingBoard Base and Pro carriers were designed to be compatible with Raspberry Pi cases. But that was before the model B+. Are there any Raspberry Pi cases currently on the market that will fit the HummingBoard Pro? |
| 14:45 | mwcampbell | The HummingBoard Pro looks like my ideal board; I just need a case for it. |
| 14:56 | Humpelstilzchen | mwcampbell: huh? I got a rpi2 case - works |
| 14:57 | mwcampbell | Oh, nice. |
| 14:57 | mwcampbell | Then maybe my existing B+ case will work with the HummingBoard Pro. |
| 15:00 | Humpelstilzchen | mwcampbell: just some minor issues, e.g. ir led has no opening |
| 16:28 | mwcampbell | Can anyone tell me if the HummingBOard Pro will fit in this specific RPi case: https://www.modmypi.com/raspberry-pi/cases/modmypi-single-colour/modmypi-modular-rpi-b-plus-case-black |
| 16:30 | Humpelstilzchen | don't think so, this one has micro usb on the hdmi side |
| 16:31 | mwcampbell | You said the HummingBoard Pro fit in a B+ case. I thought the B+ layout was the same as the 2 and 3 |
| 16:31 | mwcampbell | Or was your case for a B rather than a B+? |
| 16:32 | Humpelstilzchen | probably B |
| 16:32 | Humpelstilzchen | what was the b+? |
| 16:33 | mwcampbell | The RPi model B+ came out between the B and the 2. Same SoC, but a different board layout and some other tweaks |
| 16:34 | mwcampbell | So I guess I need a model B case, or one designed specifically for the HummingBoard Pro |
| 16:34 | Humpelstilzchen | go for B then |
| 16:34 | mwcampbell | I could get an Edge, since SolidRun has a case for that. But I really want a USB powered board. |
| 16:40 | Artox | mwcampbell: that B+ case looks really wrong |
| 16:40 | Artox | I doubt it'd fit |
| 16:40 | Artox | just try to find the sdcard slot |
| 16:41 | Artox | lego case obviously works |
| 16:41 | Artox | then there was an acrylic case from poland |
| 16:43 | mwcampbell | How about this case? https://www.amazon.com/Protective-Enclosure-Black-Color-Raspberry/dp/B008VVXMK0 |
| 16:43 | Artox | http://www.myraspibox.com/ this is one I got, but in black |
| 16:44 | Artox | and probably by another vendor |
| 16:45 | Artox | nope, that one looks wrong too |
| 16:46 | mwcampbell | Artox: I don't think that URL you gave is correct |
| 16:47 | Artox | http://elinux.org/RPi_Cases#myraspibox_case |
| 16:48 | Artox | banana robotics rpi case looks nice |
| 16:48 | Artox | with a lid |
| 16:48 | Artox | Very useful |
| 16:49 | Artox | just make sure it fits models A and B |
| 16:49 | Artox | or a competitor like Hummingboard, bananaPi\ |
| 16:49 | Artox | those that resemble the first Pi models |
| 16:52 | Artox | one identifying feature is that the side with the thernet port has space just for 2 usb ports and NOT 4 |
| 16:52 | mwcampbell | It's hard to find an original model A/B case that's still for sale |
| 16:53 | Artox | http://store.acmeun.com/products/raspberry-pi-box-blue.html |
| 16:53 | Artox | apparently the US still has some |
| 16:59 | Artox | mwcampbell: there, from China |
| 16:59 | Artox | http://www.ebay.de/itm/Raspberry-Pi-B-Case-Enclosure-High-Quality-Orange-Acrylic-Gehause-Box-Shell-/261679476892?hash=item3ced4ff09c:g:vG8AAOSwAL9UeEJh |
| 16:59 | Artox | quite cheap |
| 16:59 | Artox | not that hard after all |
| 16:59 | Artox | you know its the model A/B because it has a wide slot for the sdcard, and space for just 2x usb |
| 16:59 | Artox | and note the slod for a ribbon cable |
| 17:00 | Artox | I skipped any that fit the B+ too, to minimize number of holes |
| 17:17 | mwcampbell | This RPi model B case looks right to me: https://www.amazon.com/Raspberry-Closed-Case-BLACK-Model/dp/B00DK7ZSQQ/ref=sr_1_8/154-2273302-3849230?s=electronics&ie=UTF8&qid=1480349014&sr=1-8&keywords=raspberry+pi+b+case+black |
| 17:31 | Artox | mwcampbell: yes, looks right |
| 17:31 | Artox | if you don't mind the lack of a hole for the ribbon cable |
| 17:32 | mwcampbell | No, don't need that hole |
| 17:32 | mwcampbell | Now, how do I know if I need a heatsink? |
| 17:33 | Artox | are you getting an i4? |
| 17:33 | mwcampbell | No, either an i1 or i2 |
| 17:33 | Artox | an d are you going to run opengl stuff? |
| 17:33 | mwcampbell | No OpenGL, just WiFi and audio playback |
| 17:33 | Artox | you don't need one |
| 17:34 | Artox | oh wait |
| 17:34 | Artox | heatsink |
| 17:34 | Artox | not fan |
| 17:34 | Artox | you want a heatsink |
| 17:34 | Artox | the HB comes with one |
| 17:34 | Artox | afaik |
| 17:34 | Artox | just checking |
| 17:34 | Artox | my i1 has no heatsink |
| 17:34 | Artox | interesting |
| 17:35 | mwcampbell | Then maybe if I get an i1 and keep the CPU load down it'll be OK without a heatsink |
| 17:35 | Artox | the i1 will be good with high cpu load |
| 17:35 | Artox | sr designs with no airflow in mind |
| 17:36 | Artox | so you'll be fine |
| 17:36 | Artox | even with i2, though I would have expected the i2 to come with a heatsink |
| 17:38 | mwcampbell | An earlier version of my application ran even on the original RPi (the slowest one). What I'll be adding in version 2 doesn't require much CPU power, just WiFi. So it should be fine on the i1. |
| 17:39 | Artox | sure |
| 17:39 | Artox | but in that case the i2 wouldn't hurt, so jsut get what you're comfortable wth |
| 17:40 | mwcampbell | One more question. The specs for the HummingBoard Pro carrier include "analog audio". That means a 3.5mm headphone jack, right? |
| 17:41 | Artox | right |
| 17:41 | Artox | BUT |
| 17:41 | Artox | the i1 |
| 17:41 | Artox | ..... |
| 17:41 | Artox | check the specifications of the i1 SoM |
| 17:42 | mwcampbell | Is the audio DAC on the SoM or the carrier? |
| 17:43 | Artox | I can't remember |
| 17:43 | Artox | and I can't find what I've been looking for |
| 17:44 | mwcampbell | All I can see in the SoM specs is that they all have one digital audio serial interface |
| 17:44 | Artox | yes |
| 17:45 | mwcampbell | That suggests that the DAC for analog audio is on the carrier |
| 17:45 | Artox | ping someone, ask if the i1 will serve the analog audio |
| 17:45 | Artox | I remember a pitfall there on the i1 |
| 17:45 | Artox | but I can't pinpoint what it was |
| 17:46 | mwcampbell | I'll get an i2 if that will help, but I want to be absolutely sure I get the right thing before I place an order and wait possibly 14 business days for it to ship |
| 17:47 | Artox | sure |
| 17:47 | mwcampbell | Artox: You have an i1, right? Can you do a quick test of analog audio with headphones? |
| 17:47 | Artox | not quick |
| 17:48 | Artox | but I can |
| 17:48 | Artox | other question |
| 17:48 | Artox | pro carrier? |
| 17:48 | Artox | reasons? |
| 17:48 | mwcampbell | I thought the Pro carrier was the only one with analog audio |
| 17:48 | mwcampbell | not the Base |
| 17:48 | Artox | oh the base has the plug too |
| 17:48 | mwcampbell | Then the specs must be incomplete |
| 17:49 | Artox | I will see if I can bring the i1 up |
| 17:49 | Artox | very interesting! just read those specs |
| 17:49 | mwcampbell | Unless the plug on the Base is only for S/PDIF |
| 17:49 | Artox | rabeeh: ping |
| 17:49 | Artox | there are 2 |
| 17:49 | Artox | I got a base right here |
| 17:49 | Artox | but it is not new |
| 17:50 | Artox | back then the missing pieces were IR, pcie, sata, IR |
| 17:57 | Artox | mwcampbell: no audio on the i1 |
| 17:57 | mwcampbell | Is the issue with the SoM or the carrier? |
| 17:57 | Artox | if I remember right, one could still produce sounds |
| 17:57 | Artox | but not real audio |
| 17:57 | Artox | SoM |
| 17:58 | Artox | the sgtl5000 is missinh |
| 17:58 | mwcampbell | Does the i2 have that chip? |
| 17:58 | Artox | I remember so |
| 17:58 | Artox | but no i2 in range to test with |
| 18:00 | mwcampbell | Then the specs for the SoMs must be incomplete, because they say nothing about analog audio, for any of the SoMs |
| 18:00 | Artox | http://wiki.solid-run.com/doku.php?id=products:imx6:hummingboard&s[]=analog&s[]=audio |
| 18:00 | Artox | there |
| 18:00 | Artox | trust your first instincts |
| 18:00 | Artox | ignore any of my half-knowledge n the audio side |
| 18:01 | Artox | so it is the carriers fault |
| 18:01 | Artox | but that pwm output mentioned there hasn't been implemented |
| 18:01 | Artox | in software |
| 18:02 | mwcampbell | If PWM was good enough, I'd stick with my RPi |
| 18:02 | mwcampbell | (or get an RPi 3 to have WiFi) |
| 18:02 | mwcampbell | no, need a real DAC |
| 18:07 | Artox | okay. HB Pro |
| 18:07 | Artox | I hope you'll leave this irc less confused than you entered it |
| 18:08 | mwcampbell | Artox: Thanks for your time. Now I know what to order. |
| 18:09 | mwcampbell | I'll eventually blog about my project, and probably open source it, if it's a success. |
| 18:09 | Artox | sure, would be great |
| 18:09 | Artox | good luck with that |
| 18:13 | mwcampbell | Hmm, since you mentioned that the DAC is an SGTL5000, I should check that component's data sheet and make sure it meets my requirements before I order |
| 18:18 | Artox | mwcampbell: http://wiki.solid-run.com/lib/exe/fetch.php?tok=44f271&media=http%3A%2F%2Fwww.nxp.com%2Ffiles%2Fanalog%2Fdoc%2Fdata_sheet%2FSGTL5000.pdf |
| 18:19 | mwcampbell | Thanks, but already found that data sheet on NXP's site via Google |
| 18:19 | mwcampbell | Looks like it's what I need |
| 18:20 | mwcampbell | which isn't much, just a consumer-level DAC and headphone amplifier, which is better than what the RPi has |
