Barix Exstreamer 205 now available
icon4 10 21st, 2011| icon3Comments Off on Barix Exstreamer 205 now available

The Exstreamer 205, announced at the recent IBC trade show, is now in stock and available for order. Innovations on the device include a line level stereo input and a microSD card slot, making the Exstreamer 205 perfect for its Retail and Hospitality target markets.

Music from a hotel guest’s iPod or phone can be played, or the user can select a radio stream to listen to. In addition, the Exstreamer 205 listens on a priority channel which means that it can be built into a facility’s emergency communication infrastructure, keeping guests informed in case of any incident.

Audio over IP and the SIP Enviroment
icon4 10 14th, 2011| icon3Comments Off on Audio over IP and the SIP Enviroment

The introduction of a SIP gateway is the most effective way to merge audio over IP distribution with an already established SIP-based phone system. This is most useful when you are directing background music, paging and public address to loud-speaker systems as opposed to simply routing phone calls.

IT Telephony Article

All,

as you  might have heard in the past, Alfred Wegener Institute in Bremen (awi) has been using Barix products (namely, Barionet and Instreamer) in a science mission (PALAOA) in antarctica since quite some years now. The Barionets are used for general control and power management, while the Instreamer is used to realtime encode audio from Hydrophones and stream to Neumeyerstation located in Antarctica as well.

There is a very nice, detailed paper available from the PALAOA website (link: here), explaining details and difficulties of the whole setup.

Here is another link to the story, this time in german, with more the scientific view, sound samples etc: PALAOA.

And here is a direct link to the live stream from Antarctica, encoded by a Barix Instreamer: http://icecast.awi.de:8000/PALAOA.MP3

One thing to notice .. Barionet and Instreamer, both standard “consumer temp range” Barix products, work flawlessly since years in the setup in Antarctica, being operated sometimes at -50’C, constantly (24/7) delivering control and monitoring of the station and an IP Audio feed of the hydrophone(s).

What works that reliably in this remote location under extreme conditions should do well for you too, ain’t it ?

Monitoring of fridge or freezer to prevent rotten food
icon4 10 3rd, 2011| icon3Comments Off on Monitoring of fridge or freezer to prevent rotten food

Have you ever lost food due to a broken fridge or freezer, or did you ever find a door not shut on your kitchen fridge – after one day ?

Worst, of course, if these things happen in a place you do not regulary stay, such as a weekend cottage or vacation home !

I did this even better …. unplugged the freezer because i needed the power outlet to recharge the car battery .. then forgot to plug back in the freezer …. result, after 5 days …. quite a loss of food ! And a mess to clean up …

Barix Barionet devices can come to the rescue here ! If done right, you can monitor the fridge or freezer for both breakdown as well as open doors etc, without doing any modification or adding sensors to the fridge.

Here’s the secret: get a current sensor such as the RIBXKTF from Functional Devices (costs around $15 if you search online). you will need to install it, best in the electrical cabinet, so the source power for the fridge runs through it. The output of this specific type resembles a “contact closure” (it’s probably a transistor), so you can connect, depending on the type of Barionet you use, up to 4 or even up to 8 of these sensors.

The sensor will not detect the usual “standby” current of a fridge (while the compressor not being active), but it will definitely transmit “on” when the compressor runs.

A fridge/freezer should not be active all the time, there should be alternating periods when the compressor is active and inactive.

A typical graph is here:

Freezer Activity example

Freezer Activity Example

By monitoring the sensor for activity, you can now derive quite some information about your fridge !

– constant “off” tells you the fridge is probably plugged out, switched off or fuse blown, compressor dead etc
– constant “on” tells you the fridge is using a lot of energy, probably because the door is not shut correctly or ice buildup

By calculating the duty cycle (percentage of the fridge being on in a certain period) over time, you can even detect growing inefficiency, when a de-icing makes sense etc – of course, the “nominal” values vary by fridge and average load and need to be determined.

Calculation and alarming can be programmed right into the Barionet or done in a higher level home automation system (such as XTension for the mac – i’m using that myself).

One time rotten food/loss of content can easily cost more than the “Barionet freezer monitor”, if you already use Barionets in your house, just add the sensor …. and of course, this functionality can also be applied to heaters, fans, pumps – about anything which is meant to be on “some times” but not always …

If you want a programming example for the Barionet, contact me – happy to provide that to you as source code.

Home automation that makes sense – with the Barionet, the real-world I/O interface from Barix !

All the best,

Johannes
