Has anyone here messed around with them?

B+ =$25
2= $35

Im thinking of grabbing one to mess around with.

Yes a few of us have them. I built a PI TNC packet station and I think BigDaddy has a PI IRLP node.

I use one Pi Model B (512) as a IRLP Node.

Another Pi Model B (512) as a NTP (time) Server.

And  I just picked up a Pi2 Model B (1GB) to experiment with.


They are quite capable for the money

I currently have two B+s in the house that I experiment doing various things with. I am in the process of gathering pieces for both a packet node and IRLP node mentioned above. It may take some time, but that's my plan. They really are capable computers as long as you keep in mind their limitations.

I have one running my APRS digipeater.

I have used one to run HF digital modes (FLDIGI) in conjunction with an FT-817.

I am going to do the NTP server if I can remember.

I'd go with the Pi2. While the B+ has more support the Pi2 is coming along nicely and is
way more capable (and the B+ isn't a slouch.) I've got several, one is running my ntp server,
another is an RTL radio to aircraft transponders (dump1090), and a third is doing spectrum
analysis with alerts 24/7 using rtl_power. (And on that note, I keep picking up what looks like
a near-field burst at 137.6 MHz of under a second about once a day -- now that's a head-scratcher.)

Definitely worth getting one to play around with. I'd suggest getting an RTL-SDR dongle as well.

I'll go make one

Many don't know this, but there was the Pi B model, Rev 2, B+ and then Pi 2's came out.

I've got a Rev 1 that was my girlfriend's (now wife's) connection to my Plexmedia server for her apartment that I put together for her for Valentines day. I've got 2 Rev 2 B models, one is on a VESA mount with a TNC Pi plugged into the back of a TV at my desk. The other is a experimental toy. It gets used for site stuies (rtl_power), testing scripts, and testing ideas. One of the current ideas is trying to look into using it as a serial server as well as a virtual network device (similar to how a serial server works, just virtually sharing a network device named usb0).

I have 5 of them in use 24hrs a day.

Got one running PLEX for a TV, and another one that will be a workstation for my go box.

What do y'all use for displays on these? Both for setting up headless units and also for portable displays. I'm getting interested again.
Link Posted: 6/30/2015 10:32:21 AM EDT
I use all of mine headless. Most are B, some are B+, I think the printer's is a B+ but athat's the only one I remember for sure. Some of them are first-revision model B. I don't have a model A, but I can see the utility in the form-factor. I should replace the B with an A in the GPSD NTP server.

One is a portable RTL-SDR spectrum analyzer.
One is an rtl-sdr APRS IGate.
One is a GPS disciplined NTP server.
One runs my 3d printer.
One is a GameBoy form-factor NES emulator.
One is a remote-listening post at my in-laws house on HF, using an RTLSDR with a 20m bandpass filter and direct sampling.

One is sitting on my bench going to become a wifi-time synced alarm clock with an OLED screen.
One is sitting next to the alarm clock to become a controller for my softrock rxtx to replace the rtlsdr listening post.

Jesus I have a lot of these things...

Don't you need some kind of display for the initial configuration/setup?  What do they use, HDMI or something?

PUTTY through the network.







None of mine have displays.  But Im not using them with any need to see the actual boot process.

Setup can be done without a display if you configure the SD card on a PC with a few edits to
key files. But yes, you can use a HDMI or HDMI to DVI adapter to get a screen if you want.

I use ssh on my linux box. Heck, you can ssh -Y into the Pi and run X on the Pi and have the
apps show on your linux PC's screen as well. (That's how I do the net every week, except
it's not a Pi I ssh into.)

I have several running.  Three are running webcams using the UVC interface.  Two are doing ADS-B reception with SDR dongles.  I also have MySQL DB's running and one has WordPress on it.  Nice little devices and really cheap for what you can do.  Sadly I had one get fried by lightning back on 5/31.  I keep some spares so I was able to replace it rather quickly.

SSH is how I administer a lot of stuff. My Pi's, my home server, Microtik routers…SCADA systems for big oil.

I generally run headless for experimenting. Initial configuration is generally done via Minicom if there isn't a network connected. If there is, I'll generally just search for it using arp and then nmap -P22 -O it to make sure I've selected the proper IP.

Nope. Just drop the image on the SD card, plug the mac address into my dhcp server, and ssh in once it boots.

If it doesn't require network comms, I just use a serial console.

I guess I have some reading to do

I have a few for media centers running our TVs. We don't have cable anymore but a raspberry pi running osmc (new xbmc replacement) makes the need for cable television obsolete
