Re: [nfc-l] Thoughts on equipment

2011-09-27 Thread Michael Lanzone 
I frequently use my iPhone for both field recording and recording nocturnal
migration. I made an adapter from which I can attach a shotgun mic to for
field recording, or a a number of different microphones for nocturnal
recording. There are also a number of different recorders out there, but I
find the biggest challange is there is not an app yet that you can set to
rrecord everyday at a specified time. If anyone is interested I can get the
info together on how to make the connector and post tot the list, I would
also be happy to make some for people too if you sent me cash to cover the
parts!

Another option that I hope to make available to everyone very soon is an
open source project I have been working on for a nocturnal recorder. It will
be fairly cheap (between $200-400) depending on the options like solar
charging and hard drive capacity, but it will be a great option for this
kind of recording. I have used the design at various places over the last
several years succefully, but a few bugs still need to be worked out to make
it a bit more user friendly, I hope to be able to do that soon! I will keep
everyioe posted on its progress. The end result will be a small unit that
you can leave in the field to record, length of time you will be able to
leave these unattended will only be dependent on hard drive size installed.

Best,
Mike

[nfc-l] Thoughts on equipment

2011-09-27 Thread Scott Laurent 
The true value of NFC monitoring will be realized when there are many 
monitoring stations located around the world. One limiting factor is the cost 
of the equipment.  I was wondering if anyone has investigated the possibility 
of use the Apple iPhone or IPod Touch as a recorder? 

I think there are some reasons why this might be an excellent platform for NFC. 
First, it is ubiquitous. You can get a device almost anywhere. Second, the cost 
is far lower than a custom made device for recording because of the economy of 
scale involved with this platform. Third, there already exist many of the 
components necessary to do remote monitoring including extended life batteries, 
weatherproof cases, etc. 

The iPhone is being used by journalists for recording interviews, videotaping, 
etc why not use it for field biology? I would welcome a discussion on this, why 
it would or would not work, what hurdles need to be overcome.
