Well, yes, it's done that way, but there's no guarantee that the OP wants to do exactly that. They'll have enough fun playing around with the various mini-printers out there - they are all slightly different, and they all use subtly different command sets. Plus, there's the learning about using the ...

So just to clarify, it would be relatively safe for a person to put up a public downloading site for ROM files? It depends. Unless you have explicit releases for all the old abandonware titles you're hosting, someone might come after you. A few years back, Rare (formerly Ultimate, now part of MS) p...

When you do lsusb, what does it show up as? That looks like a generic serial adaptor, so you might be able to open the device using escpos.Serial("/dev/ttyUSB0") or similar. Sure, serial means fiddling with baud rates and the opaque stty command, but once you've got it set up, it should just stay th...

Remember that most Raspberry Pi distros default to a UK keyboard, and the @/" switch is typical of not having configured the keyboard for your country.

There's nothing wrong with the receiver board it does randomly flicker due to background RF noise it's up the Pi's coding to reject or accept incoming signals. That's a feature, rather than a bug. These boards all use automatic gain control so they can attempt to hear the quietest signal. The train...

Still running my Marvell Plug from 2009 with ridiculous uptimes. Should probably upgrade from the dodgy old Ubuntu 9.04 that's on it, but it does its job well.

Floating point on these CPUs is terrible.

I'm guessing the xxxx:xxxx is 2504:0300 for you, so:

Code: Select all

lsusb -vvv -d 2504:0300 | grep iInterface

etc.

That module has rather an odd way of interfacing to what looks like a standard USB serial interface.

You'll have to be very careful to set the pitch of the blades all the same, ot you won't be measuring like wind speeds.

Some corporate firewalls block Sourceforge (as a source of unauthorized software).

Food for thought.

Not really for me. Idling, the Dell 690's going to draw far more than 20× the power of a Raspberry Pi.

Markdown is (deliberately) a very small, simple, readable markup language which maps directly to HTML. Any extensions will break it, especially if you have to accept text from other people.

Others are a bit off topic / political but my attention was drawn to some facts elsewhere on the web in comments that have now been removed , and i thought might best be avoided in general discussion to keep major anarchy at bay.

You guys are aware that Amazon now has them in Canada, and I think generally they have free shipping for anything over $35 or so? Yes, but they're still more expensive than Creatron, my local brick 'n mortar … Incidentally, talking of Creatron: They've moved. 255 College is closed, and they're now ...

Is there anywhere that I can bag myself an old-ish keyboard, with those big apple/atari style keys and a 9-pin serial or ps/2 connection? My usual surplus store has a bunch of really nice bare keyboards that look identical to the ones used on the BBC C, new old stock. They're mostly German QWERTZ, ...

Nice project idea. Apart from staying away from potentially lethal voltages, there is no right way to do this. The way I'd approach it is to try to find the thermostat manual, either online or lurking around the house. Find out how it switches your heating system on and off. There are some which use...

Hi Steve, All I want to do is use an RPi to record noise and the times of the noise to save me having to do it. How up for experimentation and trial/error are you? This might be a little harder than it might at first appear. If you have a smartphone, I've listed a couple of readymade potential optio...

Yet another cheap nasty clone I expect. … Well, the archbeards at GNU are very keen on the Longsoon MIPS stuff since it meets their very tortured definition of “free”. Of course, no silicon can be guaranteed to be free of backdoors unless you fabbed it yourself, but that's a hardware problem, and c...

I've found that power funniness tends to destroy SD cards pretty quickly, but if you're running the filesystem from the USB things go better Good to know. Looks like you had more reliable power there than we had in the east end of Toronto. Hang onto your webserver, I've just posted your link (via y...

That's really nice. And yeah, we did get hammered this year, certainly by comparison to the last decade's mild winters. Glad the tech all worked; what did you do to ensure it all stayed working? If you've not experienced the Great Lakes, they make some interesting weather. Huge fetches of open water...

Encoding/capturing to FLAC is fairly pointless … It does put a bit more load on the processor than just recording to WAV. Sure, those files are bigger, but they take very little CPU power to write. Recording to mp3 would likely be a waste of time — the Raspberry Pi can barely do realtime MP3 encodi...

Your printer isn't too well supported under Linux.

The 3.10.x number is your Linux kernel, not the firmware. You'll need to do the sudo apt-get update ; sudo apt-get -y dist-upgrade bit to get a newer kernel, if there is one. You have successfully updated your firmware, though.

I'm wary of older USB keyboards now. I have a USB MS Natural Keyboard that flat out won't let the Raspberry Pi boot. A friend who is doing cleverer stuff spent ages trying to fix the same problem. Her keyboard was backlit, and that was too much for the Raspberry Pi without a powered hub. Now I have ...

So you gave it the full device name like /dev/serial/by-id/usb-067b_2303-if00-port0 and it still didn't work? The name depends on your hardware.
