I suppose it would be possible by taking the recorders apart and figuring o=
ut the electrical signal created by pressing the power on button, and the r=
ecord button. Then you could build an external electronic gizmo that would=
duplicate those signals on a timer. That would make an interesting project=
for an electrical engineering student.
Two inexpensive pocket recorders that do offer a record timer function are =
the Tascam DR-08 and the Yamaha Pocketrak W24. Both recorders allow you to=
set a record start and stop time, and both can be set to record at that ti=
me on a daily basis. Once the timer is set, you can turn the recorder off. =
When the appointed hour arrives, the recorder will start up, record, and t=
urn itself off again.
Of the two recorders, I prefer the Yamaha. It has 2 GB of flash memory bui=
lt in, and can accept a micro-SDHC card up to 16 GB. More important, the Y=
amaha can run for up to 30 hours on a single AA cell. The Yamaha uses date =
and time to create the file name for recordings. This helps when sorting th=
e recordings.
The DR-08 has the advantages of more widespread availability, and much lowe=
r price. Battery is composed of three AAA cells, which power the recorder =
for about 6 hours. An external battery box that provides 5V power might be=
necessary if you plan to leave the recorder unattended for a few days.
Unfortunately, neither the DR-08 nor the Pocketrak W24 have particularly cl=
ean mic preamp sections. I guess you can't have everything!
The Pocketrak CX is the predecessor to the W24. It was introduced in Fall =
of 2008, and is now discontinued. Occasionally the CX will appear for sale=
at a substantial discount. The CX does not include built-in flash memory,=
has a shorter run time (about 20 hours) on its single AA cell, and records=
at a maximum sampling rate of 16/48. Otherwise, it seems similar to the P=
ocketrak W24.
The DR-07 is the predecessor of the DR-08. The DR-07 lacks the DR-08's sop=
histicated record timer function.
