Question: What Is a Lag Switch? Answer: A lag switch is a piece of equipment installed on a home network that allows you to insert delays into the flow of local traffic to the Internet. Lag switches are normally used by unscrupulous players wanting to cheat at online video games. Lag switches are unrelated to normal network.

The SmaTrig is a compact, AVR microcontroller based multi-function flash or camera trigger. Its 15 modes of operation make it come in handy in many situations. Besides the interval modes for time-lapse photography it is equipped with sensors for light and sound for capturing short-duration events or high-speed photography. Serial Communication Interface Motorola 68hc11. It has a built-in sophisticated lightning trigger mode which reduces the shutter lag to the minimum by making use of the mirror lock-up function of the camera.
The only connection with the camera is the external trigger plug. There is no need to modify the camera in any way. The low-power circuit is powered by an integrated coin cell. Trigger modes • Manual trigger • Bulb exposure (switch toggles state) • Flash trigger • 2nd flash trigger (TTL) • Lightning trigger (uses mirror lock-up) • Sound trigger • Interval exposure 2.5 min • Interval exposure 1 min • Interval exposure 32 sec • Interval exposure 16 sec • Interval exposure 8 sec • Interval exposure 4 sec • Interval exposure 2 sec • Interval exposure 1 sec • Interval exposure 0.5 sec Manual Trigger - This is the simplest mode of operation. The pushbutton works as an extension of the shutter button on the camera (only the fully pressed state is available).
BULB exposure - Pressing the pushbutton toggles the trigger between open and closed. Long time exposure is possible without holding the shutter button down continously. This function is practical for analog cameras where long exposure noise is not an issue. Flash trigger - In this mode the camera is triggered directly by the photo-diode. This function can be used to trigger a servo flash or to build a light barrier with a laser pointer. 2nd flash trigger - In this mode the trigger responds to the 2nd flash in the sequence of two flashes such as the flash sequence.
The delay between the flashes must be less than 0.5 sec. This mode is primarily intended for servo flash control. Lightning trigger - This function is similar to the flash trigger mode, but it's optimised to minimise the shutter lag, i.e. The delay between lightning detection and exposure begin.
This is achieved by utilising the mirror lock-up mode of the camera. In the case of the Canon EOS 400D the pre-releasing of the mirror reduces the shutter lag from about 120 ms to 60 ms (see ) This is fast enough to capture lightnings easily. Check the for reader's images. The operation is explained in the following.
It is assumed that in the mirror lock-up mode the mirror is released automatically by the camera after 30 sec if no triggering occurs (as for EOS). • The camera is set to mirror lock-up mode by the user and the SmaTrig is in lightning mode. • Pressing the push-button activates the lightning mode. The camera is triggered once and the mirror goes up.
If a lightning is detected within 30 seconds, the camera is triggered for the second time and the exposure starts - a lightning was captured! Military Warrior Training Program. • After the exposure, for which a maximum duration of 4 seconds is assumed, the camera is triggered again and the mirror goes up as in step 2. The trigger waits again for a lightning. • If no lightning was detected within 30 seconds and there was no trigger impulse to the camera, the mirror is released automatically. One second later the camera is triggered again and waits for a lightning as in point 2.
During this second no lightning can be captured giving a probability of 1/31 to miss a lightning. • Pushing the button again deactivates the function. Effectively the camera is waiting for a lightning with a locked-up mirror. The SmaTrig tries to minimise the time where no capture is possible.
During the second in which the camera is 'reloaded' no lightning can be captured. This results in a probability of 1/31 to miss a lightning. Sound trigger - Sound exceeding a certain pressure level triggers the camera or the flash. This mode is perfect for high-speed photography. Popping balloons or champagne bottles are the typical trigger sources.
