JSR Intervalometer: The Basics

***Please note:*** 

***The JSR Intervalometer is no longer in production. This page remains for reference.***

The JSR Intervalometer is a camera and motion controller based on the Arduino Microcontroller. If you're into timelapse photography, this may be for you. Its many features include:

Camera:
-Basic intervalometer (either via 2.5mm plug-in cable or the IR remote. Canon, Nikon, Pentax, and Sony IR remotes are supported)
-Self Timer (0-99 seconds).
-Set number of pictures to be taken (1 - 9999 or infinity)
-Focus trigger can be set, with the length of time (0-9.9 seconds).
-Bulb Ramper. Take timelapses of beautiful sunsets or sunrises using the interactive bulb ramper.
-Shutter monitoring. During bulb ramping timelapses, shutter time accuracy is 1ms. The readout displays the desired shutter time and the actual shutter time.
-Focus and Shutter LEDs illuminated when the camera is focusing or shutter is triggered.

Motors:
-2 axis DC reversible motor control up to 1A per motor.
-Continuous movement or Move-Shoot-Move on each motor.
-Ramp up and down speeds ability on both motors independently.
-1 stepper motor can be used in lieu of 2 DC motors. The stepper speed can also be ramped up/down.
-Easy stepper connections. The wiring can be switched with the push of a button to get the right sequence.

Other Features:
-Aux Port, which can be configured as a hot shoe input (for bulb ramping), aux output (to turn on lights for plant timelapses, ect), or limit switch for your trolley.
-Backlight brightness can be set, and it can be faded (either fast or slow) after a set amount of time.
-System voltage display.
-Sound Trigger from a built in microphone to do basic high-speed photography (external flash may be required). The camera can also be triggered by a switch on the aux port.
-Flashlight for working in the dark.
-All information saved in EEPROM when unit is switched off.
-Run by 6x AAA internal batteries or external power (7 to 12V).
-SRAM check, for those who like to hack stuff (currently 116 bytes remaining).
-Internal ICSP programming connector to update the firmware.
