Topic: Applications / Is BUG right for me?

I’m done with the Teletype project, photos here: http://www.flickr.com/photos/wwward0/sets/72157…

I’ll start poking at the xBee setup now.  gigahertz wireless range is so finicky, but I think we should give it a due look before we write it off as inadequate.  In my case, I was using WiFi ad-hoc to cover a very large open space.  If you’re doing an installation in a new office building, it’s likely you’ll have a lot of good free space to bounce the xBee signals around in.

 

Willis and I are going to start banging on it shortly.  An Electrical Engineer’s tricorder, that’s what this should be.

Topic: Applications / Old school text entry

Hey jconnolly,

In your app BaseDiagnostic, in the service tracker, line 171, what is the use of KEY_UP?  I can’t find anything that tells me what that relates to on the bugbase.

Thanks again for your help.

Topic: BUGbase / bug as a remote field camera?

Everything I’ve run across about Bug says memory is 512mb.  I haven’t seen anything that talks about putting more than 512 mb of sodram in Bug.

The BUG absolutely does not have 512MB RAM.  It has 128MB of RAM.  See the specs here. 

Zoneminder (www.zoneminder.com) would allow you to do #1 and with an external sensor to detect the rain/floods, #2. I haven’t currently tried Zoneminder on Bug, the big issue being at 320×240 resolution, you need 1mb of ram

If I were to do this project, I would use the following:

  1. A temperature/humidity sensor integrated with the VonHippel module to sense rainfall.
  2. A UVC-compatible webcam capable of recording video (cheap, usually <$75)
  3. Ditch the zoneminder idea and write your own custom application using our tools, or something from openembedded that is already done for you.

Topic: BUGbase / Bug Memory Upgrades

Are there any plans to make the base physical memory expandable in Bug either by swapping out the ram and/or an extra BugRAM module(s)?

Topic: BUGbase / bug as a remote field camera?

i’m interested in finding out if a bug and cam could be adapted for use as a remote solar/bat powered field camera. I would like to automatically 1) take a snapshot everday at noon, and 2) record ~1 hour videos of floods when it rains. Is this a job for a bug? If so i’ve got some questions: Is it easy to supply power from an external battery? What is the voltage and current draw? Can a bug go to sleep in a low power mode and then be awakened by a trigger when it’s time to do something? Or, would I have conserve power by switching it on and off using another device? Lastly how much memory can a bug have?

Ok,

Zoneminder (www.zoneminder.com) would allow you to do #1 and with an external sensor to detect the rain/floods, #2.  I haven’t currently tried Zoneminder on Bug, the big issue being at 320×240 resolution, you need 1mb of ram.  Everything I’ve run across about Bug says memory is 512mb.  I haven’t seen anything that talks about putting more than 512 mb of sodram in Bug.  It shouldn’t be to hard to set something up that turns off everything not being used (e.g. just the sensor for #2 or zoneminder until noon or sensor alert) to be able to extend battery power life.

Topic: Applications / Getting SSID names?

Well, despite my misinterpretation, you have to admit that it would be a funny way to say a question is too noobish.

Is that a java way of saying I asked a garbage question?

No, that’s a way of saying that java handles memory management internally, via its GarbageCollector.  I can can create anonymous inner objects to my heart’s content, but upon the return from that method/class, the objects are discarded and the memory is reclaimed.

If anyone else light on the java experience stumbles accross this, you can see a good step by step explanation of the anonymous inner class at the following link:

Anonymous inner class.  After enough fooling around, I noticed that text in the type assist box in Eclipse.  A bunch of digging later, and I am straight.

Sorry for the dopey question 8-(
