Any ideas what to do with Raspberry Pi 2B?
>>51591420
Buy the camera add-on for it and install it in the girl's restroom.
>>51591420
Seed box?
A Bitcoins miner would be neat
>>51591466
why? so you can make 10c/year?
>>51591420
What about the zero
I want to 10 of this little suckers and do some parallel stuff
>>51591447
Seedbox is pretty good idea, but I probably wouldn't use it that often, any other good ideas?
-thanks tho
>>51591467

Why? Because you can motherfucker!

Lol he asked what to do with it and I said make a miner cuz it would be neat. Yes a gpu would be far superior (on that I have no argument). You can indeed use an pi

Shouldn't be hard to emulate ethernet through GPIO ports. Then All you need is a rj45 socket.
It would be slow, but good enough for mining bitcoins or sshing into it
>>51592170
which would make the whole thing more expensive than the CHIP that already comes with WLAN and Bluetooth
>>51592145
Ah, right. But I think you could use the micro USB port for that.
>>51592145
It has usb, I'm pretty sure you can find usb network adaptors
I've got a pi as a pvr/kodi box, thinking of getting another as a carputer or a MAME
>>51592118
Piggybacking an 8266 on the Zero will be trivial.
I can guarantee the Zero will sell twice the number of all previous Pi's combined, if only because so many people will buy them by the bucketful.
Wish they weren't a fucking charity, imagine what their stock price would be like.
>>51592175
You think the GPIO's would be able to handle 10MBit ethernet?
I mean, shit, I guess if written in a low level language you might get some good throughput.
Wonder how it'd compare to the USB Ethernet of the regular pi? And how badly it'd tie up the CPU?

Anon, hasn't anyone told you?
I'm so sorry you had to hear this way.
>>51592269
I don't have the slightest idea
I don't have a pi.
I do have an idea of implementing networking by connecting two sound cards, I think one can go over 320kbps and beyond with that.
one day, I'm gonna write a driver for that
for £400 you can get 100 rpizeros.
turn them into a cluster and that is:
100cores
50gb ram
--------------
for the price of a mid tier phone.
>>51592344
good luck finding that many in stock
>>51592344
actually connecting them to a cluster will double the price
>>51592344

Sound cards kind of have bad SNR coming and going. You might be theoretical at like 1.8Mbps, which would be something weird like 44100 bit words, and much less likely to actually work.

I'm no expert but you would have to do a maintenance/performance/time cost balance sheet thing to figure it out
>>51592419
yes. a standard gpu features hundreds to thousand cores

For hashing algorithms however, there are instructions available to gpus

I wasn't thinking about speed, it's more about compatibility.
By converting data to sound waves and back, It's possible to make networks with all sorts of things. say, an fm transmitter and receiver for example.
It would take a lot of parity bytes to make it work, but fuck me if that's not exciting

Last I checked (about two years ago desu), that broadcom ARM cpu was still proprietary, and hence there's no way you could know there's no built-in botnet.
>>51591434
Only good idea in the thread
>>51592553
In any case you're limited by Shannon-Hartley applied to your slowest link. It would take pretty robust code to change transmission on a per-link basis, especially in a platform-independent and quick way. Network drivers are typically kernel level too, this won't be pretty.
I mean think like a phone line vs monster cable 3.5mm stereo connectors. The cable can probably carry 20-44100 realistically, the phone line would only carry like 100-4000 I think, so your link over phone (limited by SNR above, which is almost definitely worse) you've got a link at 10% THEORETICAL of your fastest. You're better off just learning about the physical layer that already exists.
Additionally, a physical layer implemented over DVI or VGA would be a lot cooler desu senpai

Squeeze a TB HDD in there, and get it to routinely backup your system partition to it.
Make a cool "BackupDrive+ 32" logo to go on the plastic front of the drivebay.
Add LED screen showing date and time of last successful backup, and erroressays for unsuccessful attempts.
Put a turbo button on its panel for shiggles.

It depends on what you're building. If you expect to build something like a regular computer then yes. However, if you plan mainly using the GPIO for some custom device (slap a small screen on it and one of those controller boards for an Arduino that have some buttons and a joystick and have it be a portable emulator for old Gameboy/Gameboy Color/GBA games), it might make more sense.

That's true, but I haven't encountered anything like that (yet).

Yeah, you could probably even learn clustering concepts if you got yourself two of them.
