If you want a box that just works while you're traveling look into a little travel router like from TPLink, etc. Get one that can run OpenWRT and it will be almost as hackable as a Raspberry Pi. The Pi really isn't good as a VPN or router because it can only use USB ethernet adapters at USB 2.0 speed. Also the Pi isn't really made to handle abrupt power losses an can pretty easily corrupt its SD card if you aren't careful and yank out the power when rushing to go somewhere. In addition it's kinda sketchy to be running through airport security with a little circuit board and wires hanging off of it, etc. Ultimately I think you'll be frustrated and unsatisfied with a Pi as a little travel router. As a learning device for electronics, etc. the Pi is perfect though. Set your expectations to something that the board was designed to do and you'll be much happier.

On this note, what are some good suggestions for Pi projects? I currently have a Bittorrent Sync cloud running on a B+ which I think is awesome, and my Motionpie camera which...isn't so awesome. I've been debating flashing the SD and reloading Raspbian or Jessie in order to have it stream to an old work computer running VLC, but I'm open to new ideas.

Wanting to build a full size 4-player arcade cabinet run off a RPi2 with the ipac4 controller. RetroPie seems like the perfect fit and I'm ready to start buying parts, however I want the cabinet to be mainly a Crawl cabinet, with the MAME/MESS stuff as an option. Crawl does have a linux version so I know it will run but I'm not very familiar with the Pi at all. Is there a way to setup RetroPie where I could have an option of playing Crawl or jumping in to the emulators? My understanding is that if you have retropie on the sd card it boots directly to that without any options. I should note I haven't done real programming since college which was 99% C++ and I have no desire to actually code anything myself. Would have to rely on already-made software.

That's described in this doc.

My raspberry pi doorbell works yay! It's set up for a coffee shop drive-thru, so if the customer hits the doorbell, everyone's phone gets a push notification that someone is at the window. push button and python script sends message to push app which sends push notification to all devices on the account. I am using Instapush, which is free. Might upgrade to Pushover ($5) for user groups and downtime management. I am going to try to use crontab to schedule the script to only run during business hours, however that still sends a push notification to every phone that is logged into the app, even for the people who aren't at work.

Just an FYI: If you install FreeBSD 11.0-CURRENT for your Raspberry Pi (even a 2), the first boot will take a loooooooomg time before you get a login prompt. It's not frozen, it really is just still booting. No idea what it is that sucks up all that time, but drat does it take forever.

It seems to be on apt-get under the name "crawl." You can find the path to the actual binary with the "which crawl" command. You could probably compile it from source, too, if you want to get the absolute latest version.

Aww you got my hopes up. That's actually Dungeon Crawl, which seems to be extremely popular because every time I search for the Crawl I want I find tons of stuff for that game but not what I'm looking for. I think I'll email the devs and ask them what the odds of getting a compatible version are. Edit: Wow the dev emailed me back already. Seems like a super friendly guy. Said there was no ARM compatible version right now but seemed optimistic as they had made an android/ouya version and it ran quite easily on low spec machines. He said he wouldn't have time to make a custom build but if I knew of an easy way for him to export from unity without requiring him to do a lot of tinkering he'd be up for it. Considering the guy who made the game isn't sure I sure as hell wouldn't know any better. ChesterJT fucked around with this message at 09:08 on Nov 9, 2015 |

Hey, I recently (literally just now) grabbed a pi because I wanted to compile java and whatnot to spit out jars for me, I was trying to figure out if there was a way to just plug a USB into the pi and use that directly as an ssh interface. I saw this http://www.adafruit.com/product/954 but that literally just looks like a usb cable with female headers applied to the +5, ground, and data+ and - line. I'm assuming the TTY is intrinsically minorly different than the USB standard but I wanted to confirm this was the case before either breaking the new thing or getting a useless cable.

Yes you can do an ssh over putty on the serial line(s) For the same price you can just get an $8 edimax USB Wi-Fi adapter and throw it under the bed or somewhere out of the way. Generally now you only want to do serial if it's a truly dumb device. If you're going to ssh into it with putty anyhow, might as well get full high speed network.

There are some active components in that cable. Also you'll need to hook it up to the UART pins of the Pi and power it separately with the USB port, you can't power it off a computer's USB port. You could also use a wifi dongle to connect to your router and then SSH in like the dude above mentions, but that's dependent on having a router, etc. Also wifi can be kind of a pain to initiall set up.

I'm assuming the TTY is intrinsically minorly different than the USB standard but I wanted to confirm this was the case before either breaking the new thing or getting a useless cable. There's actually a PL2303TA serial to USB chip inside the little plastic around the connector for that cable. Serial and USB are very different at the protocol level so this chip translates between the two. That's a good cable to pick up for talking to the Pi's serial port and should work perfectly for you. If you're using a different cable you want to be careful that it's a 3.3 volt cable and not a 5V cable. Trying to send a 5V signal to the Pi's serial RX pin would damage it. That PL2303 chip is 3.3V so it's fine to use with the Pi. IMHO the easiest way to talk to a Pi is just to plug it into a port on your network's router. Raspbian will assign it the hostname 'raspberrypi' by default and most routers make that available to all the computers on your network with DNS. I think Raspbian even enables avahi by default now so if you're on a Mac you can reach it by 'raspberrypi.local' too. Once you get connected and install Samba you can even access it from '\\raspberrypi' with NetBIOS on Windows. mod sassinator fucked around with this message at 01:51 on Nov 10, 2015 |

Thanks for the help. I wanted to be able to just have a machine that I code on or throw java code to and have it spit out a compiled jar without using wifi or networking so that was the main use of it. I already have mine set up with a wifi dongle that came with it but I don't want to have to connect when I'm out and about to a wifi network that won't exist so that was the stuff. Thanks for stopping me from frying my pi too though, I wondered why it looked so simple and was so expensive so I thought either adafruit was tryin' to rip us off (which I try to think better of her) or there was something simple I was missing.

The cable is a good deal if you also do stuff with Arduino and other micro controllers (you can communicate with them even if the board doesn't have a working USB adapter), but there's better ways to ssh into the pi. Serial is really slow compared to Ethernet or WiFi. Just hook it up to your network in whatever way is easiest for you.

That ought to work but you're trusting that the public computer you have access to will let you arbitrarily install and putty. I guess if you have a thumb drive with your git repository + a copy of putty + Notepad++ you should be ok You're really not going to want to find the serial pins each time so you'll want to come up with a way to mask off the other pins, I guess. They're not pins 0,1 or 39,40, it's something stupid like 13,14 in the middle-ish, right next to the 5v and GND rails. It would be kind of neat if you could tunnel port 80 over SSH to a Cloud9 instance Actually, just get a BeagleBone Green, this is the perfect use case The BeagleBone Black is the original and costs about $50, the Beaglebone Green comes with Ubuntu preinstalled on an eMMC chip, and already has Cloud9 preinstalled. You don't have to gently caress with serial as it's both powered by and has a data connection using USB. That's one of the big pluses of the BeagleBone design is the power is also the data - you don't have to worry about Ethernet, wifi or serial to connect out. http://www.seeedstudio.com/depot/BeagleBone-Green-p-2504.html Bonus: it fits inside an altoids tin edit: BeagleBone green is on backorder, BeagleBone Black is $55 and also has HDMI out, still has Cloud9, still fits inside an altoids tin. http://www.seeedstudio.com/depot/Embest-BeagleBone-Black-RevC-Singleboard-Computer-p-1860.html

My Pi 2 does torrenting together with OpenVPN and it it hits the configured speed limit of about 10 mbit/s fairly often which is more than enough for how little I use it. load average is about ~2.5 in these cases, with one core being hit harder as openVPN only uses one core, the weak point here would be the connection stalling because openVPN is maxing out that one core it uses which means it can probably not be pushed much farther than that on the Pi2. (at least not with one openVPN instance) E: Also routers don't run on magic, they're just computers too. Lots of routers actually have specs that make the Pi 2 look like a supercomputer. The only thing that really cripples the Pi 2 there is USB and no direct in-hardware support for some things. Police Automaton fucked around with this message at 08:11 on Nov 12, 2015 |

A thing I stumbled over once because of me mis-configuring I didn't immediately figured out (tricked myself a little there) was the Pis 2 entropy pool constantly being sucked dry because of encryption and a WLAN connection being a lot slower than it should be as a result. The Pi 2 does have a hardware RNG and there's little reason not to use it, especially if you run the Pi headless. I'm pretty sure all distros made for the Pi specifically already cover all that in the default configuration already but hey, it tripped me up once.

My Odroid-C1 is in a pretty poo poo state right now. I think maybe the SD card may have gotten corrupted because a singular package would not update when updating via pacman. Now I can't access it via SSH so I decided to take a look at it and I can't get the thing to show up on a monitor. Flipping through the various resolutions in boot.ini isn't working either. Any way I can mount this SD card and chroot it and forcefully update it? Being that it's ARM I'm not sure how to do this with my X86 system.

I set up an Raspberry Pi 2 in my garage to act as a thin client for RDP to a computer I keep in my basement. The RP2 is connected via ethernet. The RP2 is connected directly to one of the ethernet ports on my router, which is also in the garage. The RP2 can connect to the internet with no problem. I can ping the router without issue. My network is set up kind of like what is shown in this diagram (black is wired, blue is wifi): The primary router runs dd-wrt and the access points are cheap routers running OpenWRT, configured to run as access points. The primary router assigns pre-set IP addresses for every device on the network via DHCP (I know what machine has what IP). When configured exactly as shown, I can make connections (ping, ssh, etc) between the laptop and the RP2. The RP2 can connect to the laptop, the router, and the internet, but CANNOT connect to any other device on my network. If I use the wifi on my laptop to connect to a different AP, I can't connect it to the RP2. None of the other devices on the network have this problem. I have an Odroid C1, a FireTV stick, a couple of smartphones, a couple of Nooks, a Linux server, and a Windows PC in the basement. All of them can talk to each other and to the outside world without issue, even with multiple "layers" of switches/access points in between them. I run a web server on the Odroid. My router (which has DDNS set up) is set up with port forwarding. I can't connect to the Odroid from the RP2 directly (ie http://192.168.1.x) , but I can if I refer to the Odroid as http://blahblah.dynamicdnsprovider.com. WTF is going on here? Why is the RP2 the only device on the network that can't communicate properly with the other devices on the same subnet? I have another RP2 (connected via wifi), and it can speak directly to any other device on the network, regardless of switches and APs in between.
