DIY or Magic Lantern: Creating an Intervalometer for Your Canon T1i

Looking to create an intervalometer for your Canon T1i without breaking the bank? There are two main options: building a DIY intervalometer from scratch or utilizing the Magic Lantern firmware. While a DIY project requires some electronics knowledge and microcontroller programming skills, it can be a fun and rewarding experience. Alternatively, Magic Lantern offers a built-in intervalometer and other advanced features, making it a more hands-off solution for many users. Let's explore both options in detail.

DIY Intervalometer: A Hands-On DIY Project

For those who enjoy tinkering with electronics and programming, building an intervalometer from scratch can be an enriching experience. Here's a step-by-step guide to creating your own:

Materials Needed:

Microcontroller (e.g., Arduino) CD4013 BCD to Binary Countdown 4-Bit Flip-Flop IC (or equivalent) Push button switch Headsphone jack Wires and resistors (as required) Optocouplers Power supply (optional)

Step-by-Step Instructions:

Set Up the Hardware: First, connect the push button switch to the microcontroller. Use a push button with an internal pull-up resistor or add one if necessary. The interval time will be set by pressing the button. Connect the LCD Display: Incorporate an LCD display to show the current interval time. This can be done using a standard LCD display module and connecting it to the microcontroller. Interface the Camera: Utilize a 3.5mm headphone jack to connect your Canon T1i. Wire two of the four contacts to close the circuit when triggered. Ensure that the optocouplers are used to isolate the camera circuit from the microcontroller. This dual-wire setup will allow the camera to either focus or take a picture, depending on which pair of wires are shorted. Programming: Write the necessary code to control the intervalometer's operations. This usually involves reading the button input, displaying the interval time, and dictating when the camera should take a picture. Use a programming language like Arduino IDE to accomplish this. Testing: Test the intervalometer thoroughly to ensure that it works as intended. Adjust the code as needed to fine-tune the performance.

Key Considerations:

Ensure proper isolation using optocouplers to safeguard your camera's electronics. A thorough understanding of electronics and microcontroller programming is essential. This project allows customization and control over various aspects of your photography.

Magic Lantern: A User-Friendly Firmware Option

Alternatively, users looking for a more straightforward and plug-and-play solution can explore Magic Lantern firmware. Magic Lantern offers a built-in intervalometer and a host of additional features, making it a viable option for many. Here's how to set it up:

Installing Magic Lantern:

Backup Your Camera: Always backup your camera settings and firmware before making any changes. Update to Magic Lantern 2.3: Download and install the latest version of Magic Lantern firmware (2.3) for your Canon T1i. Ensure that your camera is connected to the internet during the update to download any necessary files. Accessing Options: After installation, wait for 4-5 seconds or until the LED turns off after opening the card door. Press the delete button to access the Magic Lantern options menu. Using the Intervalometer: Within Magic Lantern, navigate to the intervalometer settings. Configure the interval and any other desired settings, such as ISO, aperture, and shutter speed.

Benefits of Magic Lantern:

Simplifies intervalometer setup with just a few clicks. Works seamlessly with existing camera functionalities. Supports other advanced photography features, such as HDR Bracketing and ISO and Aperture Shutter Speed Control during video mode.

Important Notes:

Installation may void your camera's warranty and might cause damage, but many users report no issues. Wait for the LED to turn off before accessing the Magic Lantern options to prevent data corruption.

Both DIY and Magic Lantern options offer unique benefits. For electronics enthusiasts and those looking for a high degree of control, the DIY intervalometer path is rewarding. For users seeking ease and convenience, Magic Lantern provides a hassle-free solution with advanced functionalities. Choose the approach that best suits your needs and skills.

Conclusion

Whether you opt for a DIY setup or utilize Magic Lantern firmware, your Canon T1i can be transformed into a powerful time-lapse and long-exposure photography tool. Explore the possibilities and capture unique moments with precision and creativity.
