wireless RF remote control system
for Nikon compact flashes
deutsche Version hier klicken
Version does not exist any more. There is a new System
would like to present a "small" hobby project here on
which I was working for over a year:
my RF solution I not only can trigger the flashes, additionally
I can control power, wakeup from standby or let them work as
stroboscope. 'Ready' signal is processed so that the receivers will
tell me when all flashes are ready to trigger again.
system consists of a transmitter, plugged onto the camera, three
receiver units (could be seven) and the controller unit.
The system provides seven channels plus one broadcast channel. It can address seven receivers (plus one address for all receivers). Each receiver can control four flashes, 28 in total. The power of every single flash can be configured individually.
Rf transmission is hamming coded. Although no error correction is provided, errors can be detected so that theoretically no unwanted trigger pulses can occur. By the nature of this RF technique missing triggers cannot be avoided.
All units are powered from Nikon EN-EL4 batteries, so power should'nt be an issue at all. Additionally all batteries are protected against under voltage discharge. Besides the receiver and controller units contain battery chargers which can be fed by any power supply with output voltages between 6...12 Volts.
transmitter on the camera triggers the flashes fast enough to catch even
a 1/160 sec window.
powerful LEDs on the transmitter front provide an additional focus
support light. Not that powerful to focus on far objects but powerful
enough for portraits. This is just helpful in situations where the
focus light on the camera is covered by the lens hood or just accidentially
by a fat finger ;-). This focus light is immediately switched off
when the camera shutter release button is pressed to it's second
push point, preventing this light to be visible in the photo.
receiver controls up to four flashes. Power can be set individually
for each flash and all settings can be stored in the receiver so
that all settings are available on power-on again.
stroboscope mode can trigger the flashes up to 15 times automatically.
The minimum interval starts at 20ms while the maximum interval
lies at 5 seconds.
As the receivers can beep on certain events, it is configurable on which events the units should beep. At least all beeps can be switched off completely.
In certain situations it may be desireable to prevent flashes going into standby. So, just tell them.
And completing the receivers as 'egg-laying-wool-milk-piggs' they can be configured as remote control units for the camera as well including the abillity to activate focusing before triggering the camera. Thus the receiver can emulate the release shutter button for both focusing and triggering.
there is another unit ... the controller. With this unit the flashes
can be configured via the receiver units. On an LCD display one
can select the desired flashes and set them as required. The flash
list contains 28 units but you can configure this list to less receiver
units to have a more compact list.
LED Focus Help Light (Update: 2009.02.21)
Above show is the LED focus help light. It will switch on immediatly as you push the camera trigger half way down and stay on for adjustable one to four seconds. Only if you press the camera trigger full way the LED FHL will immediatly switch off again so that the FHL will not contribute to the foto.
