Re: Pi Time Capsule

Here's another way of setting up a stock raspbian system to act as a time capsule:

It worked well for me, though I'm now backing up my Mac to a FreeNAS server.

Scanner controller

I've got two older Epson all-in-one scanner/printers, and neither one prints very well any more. That doesn't bother me much, though, because I now have a nice color laser printer for all my printing needs. However, it means the "copy" function of those printers doesn't work any more, and that's use...

Re: Use rPi as a Time Capsule - another method

The Time Capsule (whether on an rPi, a true Apple unit, or some other server) needs to be network-accessible by your Mac for the backup to run. The easiest way to do that is if they're on the same LAN. If you're in a remote location and can VPN in to your home LAN, that would work as well--though th...

Re: Wine making

Check out the TeensyPi project (http://www.teensypi.com/)--it uses a Pi in combination with a Teensy (small Arduino-compatible board) to monitor and control temperatures. It's intended for beer, not wine, but the same principles should apply.

You can't readily get there from here. You need an ATA like the Obi100 (www.obihai.com) for about $40 US.

Re: File sharing with OSX

so I added my external HDD so it looks like this /media/matman_backup How did you do that? If you only changed AppleVolumes.default, that won't do it. What are the contents of /etc/fstab? What's the output of running "mount"? And do you in fact have a subdirectory in /media/ called matman_backup?

I uploaded my music on hold files using scp from my main computer--with a Mac you can just use the scp command from the terminal; with Windows you'll need to find an scp app.

There's a lot more support on the PBX in a Flash forums--pbxinaflash.com.

Re: Time Capsule setup with Raspberry Pi

If it's asking for a username and password, try giving it a username and password--a combination that's valid on the Pi would be good. Unless you've changed from the defaults, that would be pi and raspberry, respectively. And make sure, as scoopdevon posted on 1 Jun, that the pi user has write acces...

Yes. Mount the Time Machine to a directory on the Pi (something like /mnt/timemachine/ would make sense).

Re: logging DDM data to RPi

From the manufacturer's data sheet, linked from the page you gave: "All new APPA 100 series has RS-232 optical interface to connect to PC for data acquisition." RS-232 is a serial standard, so the USB interface is likely a USB-serial converter. Fire up a terminal program, connect it to whatever USB ...

Re: logging DDM data to RPi

None whatsoever, other than you'll first need to find some documentation on the data format or figure it out yourself. Does it present as a USB-serial device? If so, that'll likely make it easier to work with.

Without knowing more about this DMM, I'd first look into whether the QtDMM software is compatible--just do "sudo apt-get install qtdmm" at a command line to install it.

Re: Satellite phone and a weather balloon

That's an i386 .deb file; your rPi doesn't have an i386-type processor. Unless you can find a version of the software compiled for the rPi, or find source code to compile it yourself, this software won't work.

Re: Digital multimeter(DMM) and Rpi

As stated, most DMMs don't have the ability to talk to other equipment until you get into rather expensive models, and even many rather expensive units don't do this (my Fluke 87V, for example, a $300+ meter, doesn't have a computer output). Here's one inexpensive model that does have this ability: ...

Re: MAX3232 on RadioShack 276-159B, RS232-to-TTL Conversion

Polarized caps aren't necessary. They're shown in the schematics because, in times past, you'd almost certainly need a polarized cap to get 1 uF. Today, you can get cheap nonpolarized ceramic caps in that range, which makes the process easier. I'd generally follow the recommendations in the data she...
