DIY NEX Intervalometer

Today I'd like to present my remote control for my first generation NEX cameras. They had only an IR remote control input for triggering the exposures externally without touching the shutter button. I also looked for a possibility to work in bulb mode for extra long exposures > 30s. For lack of a useful commercially available product I built one myself.

Let me describe the whole chain:

I. Intervalometer by Godox, with many features for timelapse photography

II. IR Remote Controller by JJC

III. DIY PCB with an ATMEL Microcontroller performing a monoflop action when the intervalometer activates the trigger output. This is necessary to simulate a manual button click to the RC device. For the electronic guys among us: the µC is powered by the intervalometer's power supply. The trigger output is a MOSFET in open-collector wiring, it's connected in parallel to the RC shutter release button.

IV. This is the IR LED of the RC device, soldered to a long cable. I've separated it from the RC to get closer to the NEX' IR input.

In revision B you can see how I fix the LED to the camera. I'm using a simple cable tie loop to fasten the LED in front of the IR sensor of the NEX camera.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
