gentLED-AUTO, timer/intervalometer for IR triggerable cameras and camcorders.

NEW: Click here for a demonstration video!
The gentLED-AUTO is an intervalometer (interval meter) for repeatedly triggering digital cameras and camcorders that have IR capability. This intervalometer sends an IR signal that fires the camera shutter at preset intervals. Once switched on it repeatedly fires the shutter without operator involvement, making it ideal for taking time-lapse sequences, photographs where the operator isn't present, and astronomy "bulb" exposures.

Uses a precision 22turn adjustment to allow exact setting of timing, easy to use and for security it wont change accidentally! At switch-on a short flashing sequence informs the operator of the interval to the nearst second. For full details on how this works see the bottom of this page.

Completely self contained, with built in on-off switch and battery (included unless prohibited by the Postal Service) this unit gets you any repeat between 1 second and 30 minutes in three ranges. 18grams (0.6oz) & only 38x28x18mm (1.5"x1.1"x0.7"). 100,000's of camera triggers on one CR2032 cell!

Canon HV20 / HV30 / HV40 are popular timelapse camcorders Sony NEX-5 is a popular Timelapse CameraAvailable for cameras (by pressing the shutter via the IR facility) & (pressing Photo via the IR facility) for camcorders
this is all you need to generate the images you need. Use the tables below to select camera/camcorder model respectively.

Notes on setting up gentLED-AUTO

The time interval between triggers is set with an internal link and a precision 22 turn adjustment.

1 second to 35 seconds

5 seconds to 5.5 minutes

30 seconds to 30 minutes
This makes the unit very secure, and it is difficult to accidentally change the timing.
These notes will help you quickly set-up the unit for any time between 1 second and 30minutes.

First set the range required, 1, 2, or 3, the link is located inside the unit beside the OFF/ON switch:

  1. 1 second to 35seconds.    The link is stored with only one pin connected.
  2. 5 seconds to 5.5minutes.  The link shorts out the 2 pins nearest the OFF/ON switch.
  3. 30 seconds to 30minutes. The link shorts out the 2 pins farthest from the OFF/ON switch.
Fine adjustment on each range is made with the gold adjustment screw on the lid of the box.
To make setting up range 2 and 3 easier there is a fixed relationship between them. The easiest way to set these longer ranges is to set range 1 then compute the interval on range 2 and 3:
  1. Set the time on this range, being the shortest range it's easier and quicker to adjust.
  2. This range is 10x slower. Take the range 1 time, subtract 0.5seconds then multiply by 10.
  3. This range is 60x slower. Take the range 1 time, subtract 0.5seconds then multiply by 60.
If you don't have a clock, or stopwatch, handy then the unit can help you!
The very first red flash after switching on sends a 3 part code as follows:
  1. 1, 2, or 3 short flashes indicating what range the link is set to.
  2. 0, 1, 2, or 3 long flashes indicating tens of seconds delay on range 1.
  3. 0 to 9 short flashes indicating units of seconds delay on range 1.
e.g. 1 short, 2 long, 3 short is Range 1 with adjustment set to 23seconds.
e.g. 3 short, space, 8 short is Range 3 with adjustment set to 8 seconds, approx 7.5 minutes.

At all other times the red light only flashes very briefly to indicate the IR shutter signal has been sent.

Notes on Astronomy and cameras with sleep mode

On models supporting Cameras (not Camcorders) range 3 is unique in that it emits a double burst of IR each interval about 2 seconds apart, this can be used in 2 ways:

  1. Some cameras (e.g. Sony NEX) allow bulb mode - one IR pulse to start and one to stop.
    The double flash allows a series of long exposure astronomy images to be collected back-to-back. In this mode the interval sets the exposure time.
  2. Some cameras (e.g. Pentax) can be set-up to "sleep" and be wakened up with IR.
    So the first flash wakes the camera and the second takes the picture.
    With the camera sleeping between shots batteries can last much longer.
For other users, delays above 5.5minutes (i.e. using range 3) means you get double shots each exposure. With today's large memory cards this is a small inconvenience. Post shooting you can use Windows Explorer in "thumbnail" mode to view files. Set the window to make the thumbnails 2 across then "rubber-band" one column and delete.
