DINTERVALOMETER, A CUSTOM MADE INTERVALOMETER FOR DSLR CAMERAS
If you want to take a timelapse with your camera, it may be helpful to use an intervalometer. It is an attachment or facility on a camera that operates the shutter regularly at set intervals over a period, in order to take timelapse series or take pictures after a set delay.
Daniel Knezevic had developed a custom made intervalometer for DSLR cameras. Dintervalometer (Deni’s intervalometer) enables cameras to shoot time lapses and allows shutter speeds longer than the 30s.
The Dintervalometer is built with an Atmega328P clocked at 10MHz, a PCD8544 84×48 pixel monochrome LCD display with a backlight, a 3.5mm male jack connector, and two tactile push buttons all combined together on a small PCB.
- Intervalometer: It is used for time-lapse photography. It controls how often, how long and how many shots are taken.
- Bulb mode: It allows to take time exposures longer than 30s.
- Charging via USB
The Display & Backlight
The PCD8544 LCD display can be powered using 3V3 and it draws very small amounts of power (around 200uA) making it extremely good for use in battery powered devices. It is typically used in Nokia 5110/3310phones, and it interfaces to microcontrollers through a serial bus interface (SPI).
A custom made backlight were designed to allow using the Dintervalometer in the dark without an additional lamp. It operates like a backlight of a cell phone: it is active for 10 seconds when the user presses a button or the Dintervalometer finishes some job.
