MIOPS: Smartphone Controllable High Speed Camera Trigger Review

Part Three: The LASER Sensor

 

Today I tackled the LASER Sensor on the MIOPS trigger. I used a cheap laser pointer, easily and cheaply available from Amazon and other online sources or perhaps in your local shop. It doesn't matter which colour is used. To use the MIOPS with the laser sensor, one has to point the laser in to the light diode on the top end of the unit. When the laser is beram is broken, either the flash or your cmarea will be triggered, depending on what you are doing and your needs. For my purposes today, I had the MIOPS connected to my flash. 

To use the sensor one has to adjust three settings: The threshold, this determines how sensitive the trigger will be, the delay; once the beam is broken the sensor triggered my flash. This is very much a trial and error exercise and if you are working with items of different weight and size it can be a little frustrating. If you are able to set up some kind of rig whereby the height and weight of an item to be dropped is constant, it can be much easier and a more repeatable process, this is in the perfect world though and I don't live there :-). Finally set the number of shots you would like to take after the beam is broken. I can think that this would be great for wildlife, capturing a burst of activity.

Once you have done all of this you are ready to go. Today I experimented by dropping some balloons on to a dart and also by dropping a ball bearing in to a small shot glass filled with talc. The timings on each of the balloons were different, one too early, one too late and one just about right, although this will  obviously depend on what you want for your purposes.
