I just can't believe they didn't put any drat holes in the board for mounting.

Space Gopher posted:One of the big attractions for this is "feel free to gently caress it up, you can just restore it!" You know, from that other PC you have. Not to mention, it'd sure be nice to teach people to use modern programming tools, rather than just saying "well print() statements were a good enough debugger for me..." Even if you do manage to screw up the boot, it's not like you need 1:1 desktop per raspberry pi. You just need access to a single public PC to download a unfucked SD image and load it on there. In fact, I'm betting you could get a cheapo USB SD reader, and have your friend's pi recover your SD card for you, no desktop PC at all.

So, are there people working on porting android to this? I was just discussing with a friend how this would be pretty neat for a carputer running android possibly. Is there anything about the board that would make it unsuitable or especially difficult to run Andriod on?

Well, I mainly want (my first) one for HTPC/XMBC use, but I'm also thinking this could be a nice robotics platform, probably enough power to do a bit of video processing: plug in USB camera, strap to roomba, or better yet XV-11 with laser rangefinder and program it to do all kinds of autonomous cool stuff.

I don't know a lot about the various arm processor versions to say if it would be easily portable to raspi, but Smoothie firmware is a CNC controller firmware designed to run on ARM (Cortex M3) processors. As far as I know it is a standalone firmware that doesn't run on top of any OS like linux. Besides porting or writing the controller software, the other main issue I think is whether or not there is enough GPIO pins exposed to handle 3 (or more) motor controllers, plus various other accessories(for ex. in 3d printing, hotend heater/thermistor, heated bed heater/thermistor, 4 axis X/Y/Z/extruder, limit stops, fan control).

Aurium posted:Interestingly enough, at this point I've argued on both sides of this issue. A fully assembled RAMPS board (not including the Arduino mega or Pololus) runs about $85. So basically what I'm getting at is that if it is possible to make a daughterboard for raspi that can break out enough pins over i2c or whatever to perform similar function as RAMPS, for similar price, then that could possibly make quite a few people happy. The whole intermediate parallel interface idea is foreign to me, and seems extraneous. Edit: This diagram shows how all the stuff interfaces with the RAMPS board. Dual extruder(what the 5th stepper driver would be for) is optional and not widely used at the moment.

I just stumbled across this thread on the raspberry pi forums about processor configuration/ overclocking. Something which hadn't really crossed my mind before, but could be a lot of fun. Bascially you can overclock by simply editing a text file. Dom says he's already been running 1Ghz(from a baseline 700Mhz) and short tests at 1.15Ghz. I wonder how much higher is possible with addition of heatsink/heatsink+fan/liquid cooling/dry ice/LN2

Got the pi in today. Running the main debian image from the raspberrypi.org. This thing is super annoyingly slow, more than I thought it would be. I already overclocked it to 1Ghz. I hope there is still much room for improvement from software optimizations.

Shane-O-Mac posted:What are you using it for? I wanted to get one as an HTPC, but if it's performing badly I may change my mind. The plan was to use it to replace my old Xbox 1 running XBMC. Based on the current performance i have no idea how it will be able to do that, I'm hoping it's all in the software optimizations, I don't know if they are taking adavantage of any video acceleration yet or whatever other special instructions. There's no RaspBMC image yet to try out, so gotta wait a while.

I was searching for a fast SD card to be used with the pi, and I found these SD card benchmarks from Tom's Hardware: http://www.tomshardware.com/charts/2011-sd-cards/benchmarks,125.html Shows a whole bunch of charts using different benchmarking programs. I'm not 100% sure what to make of all of it as far as what's the best card for general linuxing, but I ended up just buying one of the "Patriot EP Series (32 GB, UHS-I)" because it seemed to perform in the top tier for most tests, and at a really nice price for all that capacity. Also, what the hell is going on with "Samsung Plus (16GB, Class 10) MB-SPAGA" in some of the h2benchw results? It scores like 1000 times faster than the other, but this seems like some sort of error since the other benchmarks show nothing like that. Maybe some weird caching thing going on with the controller on this chip? Or just incorrectly recorded test results?

You could do the same with a couple of these on the end of the ribbon cable instead of using a whole pcb. http://www.digikey.com/product-detail/en/SIP110-PPPC-D13-ST-BK/S9332-ND/2095341 There's probably also a single 2 row plastic connector somewhere with .3" row spacing that would fit a breadboard too. Edit: I think this one should work(couldn't find a 26pin, so I went up to 28): http://www.mouser.com/ProductDetail/ADAM-TECH/FDP-28-T/?qs=TTVbHWoAP%2fQP8HTx%252b5csmA%3d%3d peepsalot fucked around with this message at 09:57 on Jul 3, 2012 |

Just wanted to chime in to say that RaspBMC has been working really well for me. Haven't come across a file that it wouldn't play well. The only slightly annoying issue is that the sound in the beginning takes a few seconds before it gets going for some reason (it stays in sync w/ video once it starts), and then the last couple seconds of video just freeze-frames and the audio cuts out. I've been using it with the official XBMC Remote for Android, which is really nice.

Wow xbian really is great, I hadn't heard of it before and just switched over tonight. The difference in menu responsiveness is hard to believe. And I didn't even know HDMI could do this whole CEC thing, it worked first thing with no configuration required at all. No need to use android xbmc remote anymore

porktree posted:Who's running Xbian? I put it on my Pi and let it chug along and update the libraries (overnight) - but I seem to be having a lot of issues streaming even low quality (SD) content from my media share. The same stuff runs without a hiccup through XBMC on my ATV 2, or streamed wirelessly to my iPad (using Airvideo). I'm going to load up a card with RaspBMC and see how that does with playback. Or, are there any tweaks I should try with Xbian? It shouldn't take overnight to update. Only took a couple minutes for me if i remember correctly. Are you using a wifi dongle with a spotty connection or something? Just sounds to me like you are getting terrible network speeds.

Well, that's a shame, xbian was working very well for me. I didn't realize there was an issue with GPL violations. Judging by Koen's reactions, he sounds a bit immature to be leading such a project. So what's the consensus on raspbmc vs openelec. I tried raspbmc a while ago and was frustrated by the unresponsiveness of the menus. I guess this turbo update should hopefully fix all that though. I haven't tried openelec yet

I haven't tried OpenElec but the one thing that turned me away from it when I looked at it was that it's not based on any distro and therefore doesn't have a repository of packages that you can install if you feel it is missing anything. Raspbmc and Xbian are Debian based so you can get all the debs you want.

Raspberry pi ethernet port is only 100Mbit. I would imagine it would still be quite a bit faster than reading SD. I can't say I've tried networking booting yet though.
