ASK ME ABOUT MUTILATING MY PET TO SUIT MY OWN AESTHETIC PREFERENCES


So I got one of these when they first came out cause I wanted to use it to stream movies from my computer to my TV but I've got not the time nor the patience to learn how to set it up. So if any of you goons wanna buy it, they shipped it today and should be here in a couple days. I'll sell it to you for what I bought it for which is $35 bucks plus the price of shipping. Just lemme know if you want it.

Is it the model B? I would be interested as long as the shipping isn't too much. How much do you think it would cost to ship to NH?

Mine is installed with Debian on an 8GB card and currently acts as a downloader for my server backups. I've installed Apache on it, and as soon as my Xbox camera arrives it'll be a remote office monitor with web interface.

It runs fine from a BlackBerry phone charger which outputs the required 700mA.

I still have my Commodore 64, and when Jack Tramiel passed earlier this year, I pulled it out of the closet and have been hacking around on it for the past few months. Thanks to the still-vibrant scene, I've got it talking on the intarwebs via ethernet, and finding all kinds of things to run on it.

One of the things I keep bumping into is the fact that, despite how much development has continued in the past couple decades, I'm still hacking around on a 30-year-old platform. It will never be useful/valuable beyond the novelty of using something that old to do something (anything) practical. There are folks out there that run web-servers on stock C64s, but I'm not sure I see the long-term value in that.

The RaspberryPi, on the other hand, seems an eminently hackable platform that can be turned into something noteworthy. There are lots of good ideas what to do with this, and I'm having some of my own ideas (a web-server frontend to heyu to run the lights in the house) what to do with this.

Decided upon a remote sentry (access point, comms centre, sensor array) for my caravan.

So far:

Enabled SSH
Changed start.elf to high ram allocated to CPU
apt-get upgrade
Installed Samba

Looking into RPI.GPIO for Python

It's a neat bit of kit. Wouldn't recommend the default Debian install for use as a desktop PC - too slow and ram limited.

Looked a little bit into OpenBSD, and apparently BroadCom, who makes the SoC, are really tightassed about docs and specs. So far, some sort of binary bootloader is necessary, and that's not really available yet.

I think there's a fair chance we'll get the BSDs on board as well, but not right this second.

I've been playing a little bit with mine, getting some first impressions. First of all, it's not responsive, especially in X. The browser takes double-digit seconds to load, and everything feels sluggish. I'm sure me running it against a full HD TV didn't help, and the graphics are as good as non-accellerated, so I have hope.

Can't really get a good setup, but managed to squeeze about 23 mbit/s inbound and about 15 mbit/s outbound through the LAN interface. These values might be SD card limited.

In its non-overclocked state, it doesn't get warm at all.

I've looked into stuff some more, and apparently the GPU boots up first, and then powers up the CPU. So the GPU is, in effect, the bootloader, and that particular piece of code is binary, and will probably never be released in source form. And even if it did, it would require a specific Broadcom GPU compiler, which we won't get either.

It appears that the GPU firmware expects a VFAT formatted partition on the SD card (at the beginning, most likely) that contains certain files (bootcode.bin, loader.bin, start.elf) and these can then boot a kernel. I'm no OS guru, but it seems plausible that other OSs could be booted that way.

Yes, the ultimate effect of the closed-source loader binaries is to find a file called kernel.img on the first partition of the SD card, load it into memory starting at address 0, copy the contents of cmdline.txt to address 0x100, and start the ARM going with a PC of 0. That ought to be enough to get your OS of choice running.

Doing a bit of overclocking, 900 CPU, 500 ram, GPU and voltage stock.

Got some spare Radeon GPU ramsinks, and stuck them to the chips on my Pi.

Runs quite warm at 700, 900 is very warm. Not going to burn you though.

Unnecessary. Heat isn't the limiting factor when overclocking this thing. Someone's run one for months at 1GHz with no extra cooling at all.

Looks like I missed UPS with my delivery today. I never got a shipment notification, or really any notification outside of order received months ago, but that just made it a nice surprise to come home to! Now to make a nice case for it.

I was thinking something simple and plastic I can velcro to the back of my television, or just turning a block of wood into a nice looking and 'hidden' computer case. The options I've found online all look like they were lasercut from a sheet of plastic.

Paper burns at about 451 F, or 230 C. I doubt you will get it that hot.

I saw mention on the RPi forum that using paper for "cases" was something that they considered, and that aside from damage to the RPi itself, fire was extremely unlikely. One of the founders put it like "Look, it's 5V at 700mA or so. By design, nothing gets hot enough to be a concern at all." The subsequent discussion drilled the point home - If you're using a paper case for your RPi and it catches on fire, something bad (i.e. unusual) has happened - like damage to the board/components/etc causing a dead short somewhere. Still, the amount of current involved is pretty low, so things have to have been going really badly for fire to be a result.

I'm still waiting for mine to arrive, but I'm curious how hard it is to interface with the I2C bus. I found a bunch of low-cost 16 channel LED drivers that use I2C for control, and would love if they have basic "send 'blah' to 'address'" drivers so I could do all the work in userland without having to write any kernel-mode drivers.

The appeal of having my own personal (monochrome/low resolution) jumbotron is too much to pass up.

Which led drivers are you looking at? I'm looking at some led projects, am on the lookout for some cheap drivers!

I settled on the NXP PCA9635. 16 independent 8-bit channels, with additional functions for easy 4-color mixing, plus an 8-bit master and strobe effects. Nice little chip for $2.50 each, although it's only available in a TSSOP surface mount variant which isn't the easiest thing to work with at home.

v True, but SMD soldering takes a bit of practice and a good pencil-tip soldering iron.

TSSOP is easy to deal with if you're making your own pcb or if you can find an adapter board that isn't terribly overpriced.

Do you suppose it's be possible to use the Raspberry Pi to run the standard Reprap software? It already relies on an external motion controller (Arduino Mega), so real-time programming wouldn't be an issue. It wouldn't be as cool as programming an ARM board to run the machine by itself, but it could be worthwhile for many applications.

In all likelihood any of the linux reprap host software will run on a RPi without modification.

One note I would like to make is that slicing/tool pathing/gcode generation step is rather processor intensive. It's still be very likely to run unchanged, it'd just be slow on the not so powerful ARM in the RPi. Feeding the printer already generated gcode would be well within its capabilities.

Wow kudos to Newark/Element14 for having their act together now. Glad I went with them over RS.

They played ping pong with my delivery date for a while, up to and including pushing it back by two weeks the day before it was due to ship. Then I happened to check again yesterday and wow, it had already shipped (a week before expected). Then purolator just showed up and my door and handed off the package.

Time to go find something to power this thing. I'm pretty sure I don't have any old phone chargers, or even a powered usb hub, anymore.

That's any crappy GPU these days. It's quite easy to have hardware decode for preencoded video and play it back fast - it has no bearing on live rendering performance. And even bare bones smartphones from a few years back have decent 3D performance.

Thanks for the link! I just got an RPi yesterday afternoon, and have been hacking around on it a bit since. I hadn't got 'round to investigating XBMC with any seriousness yet, so this comes in handy.

The image is a couple hundred megs, and it goes through a bit of a setup routine on first boot. It takes about 20-30 minutes to get everything in place. I was a little disappointed that it doesn't (yet?) seem to know how to do DLNA/UPnP (I have a Servio box on the network to serve up a bunch of stuff), but it was quite happy to mount a regular ol' USB thumb-drive and play TV:



Performance isn't stellar by any stretch of the imagination, but it does work. It does behave pretty well with straight-up playback; I didn't see any stutterring or skipped frames. XBMC can overlay the video with UI (as shown), and the RPi doesn't really handle that very well. Shortly after I took that snapshot, I had to power-cycle to regain control. Also, cueing back and forth in a file is a little rough. For casual viewing, though, it seems to be pretty reasonable. Very promising progress...
