JSR Intervalometer FAQs

Which cameras work with the JSR?
The JSR is designed to work with almost any DSLR camera. However, I only supply a 2.5mm cable to connect it. This is the standard remote connection on many of the Canon DSLRs. You will have to supply your own cable if your camera has a different connector. See here for some information on the different connectors.
The bulb ramping feature should work with most Canon Cameras. I have tested it on the 60D and T3i and it works well. The bulb ramper will not work with Nikons. It is untested on other makes.
The IR remote should work with Canon, Nikon, Pentax, and Sony cameras that support IR remote shutter release.

Which motors will it run?

The JSR will run 2 small DC motors that draw a maximum of 1 amp each. This should be sufficient for most camera dollies and diy contraptions out there. You can also run a single stepper motor (4, 5, and 6 wire steppers all work). Be careful not to exceed the 1 amp limit. Even a small stepper can exceed this current rating.

How long do the batteries last?

The batteries last approximately 1 - 1.5 hours; less if it is running motors. If you need extended time, there is a jack to plug in external power (7-12V, DC).

What is high-speed photography?

High speed photography is capturing fast movement that is normally difficult to photograph. Balloons popping, projectile impacts, and objects breaking can all be photographed using high speed photography. This is usually done in a dark room with the camera is set up and the shutter open. When the action happens, an external flash fires. The short duration of the flash "freezes" the movement, and is enough to expose the camera's sensor. Normally this is done using a sound trigger which listens for a certain sound level, then triggers a flash. The JSR has a built in microphone and user interface to trigger a flash used in high speed photography. 

Can the JSR do ________ ?

The JSR is a very capable intervalometer, but undoubtedly, there will always be some things that it can't do. The software is programmed using the Arduino IDE, which is an open source electronics platform. The lanuguage is C++, and is relatively easy to use. You are more than welcome to reprogram the JSR to suit any needs that you have.

How do I upgrade the firmware?

Right now, there is a 6 pin ICSP connector inside the JSR. You access it by removing the 4 screws from the faceplate and pulling off the LCD. You will either need an Arduino UNO or an external programmer like this to interface your computer with the JSR.

That's complicated. Can you put on a USB to upgrade the firmware?

Realistically, I don't expect very many updates to the JSR software once it is released but I am looking into the feasibility of a USB connection.

How do I order one?

I'm currently not taking orders. You can send me an email (jsrintervalometers@gmail.com) with any inquires.

What is included?

JSR Intervalometer
3.5mm to 2.5mm shutter cable
2x DC power cable to connect motors or an external battery.
Wall charger (120-240V, US plug only)
Worldwide shipping to most places.

What will I still need?

-If your camera doesn't support the 2.5mm shutter release cable, you will need an appropriate adapter or connector.
-If you want to do bulb ramping, and your camera doesn't have a PC cable jack (for the flash), you will need a hotshoe adapter (something like this). Also, you will need a connecting cable PC-3.5mm (something like this ) to connect the camera hotshoe to the JSR.
-If you want to do high speed photography, you will need an external flash. The hot shoe adapter and PC-3.5mm cable above will work for this too.

How much does it cost?

The JSR is not available. Have a look at the JSR DIY Kit or the Bulb Ramper Shield for Arduino.

How do I pay?

I will send you a paypal invoice when your JSR is ready to ship.
