Adapter for Photographer Tools

Photo01, the diagram of the power adapter, which allows the photograher Tools to
control a solenoid valve (to take pictures of collisions of drops of water), a motor or a relay.
As you can see, the power adapter is very simple: A resistor, a transistor and a diode.
If you wish to drive a valve, a relay or a small engine (as on Photo01),
a low-power transistor is sufficient.
By cons, if you want to drive bigger engines will require a transistor, that can withstand high power.
I mention the 2N3055 which supports up to 15 Amps (at 12 Volts, it is 180 Watts max).
Caution! You will fix the transistor on a radiator or in a metal box, for dissipate heat.
Example of setting of the Photographer Tools in detector mode, for doing collision of water droplets:
Using OUT1, in INTERVALLOMETER, DELAY = 10s (this will be a collision of drops every 10 seconds),
DURATION = 10ms, and SLEEP = 10ms and REPEAT = 1.
Every 10 seconds, two drops of water will be distributed through the valve with an interval of 10ms.

Photo02, my power adapter (small power) that I made??.
I used it to drive a solenoid valve. Photo03, the solenoid valve and the power adapter.

The power adapter can be connected on OUT1, OUT2, OUT3, and also OUT4 OUT of "remote module".

Photo04 is an adapter for AUX1 and AUX2.
By default, I have made ??available +5 Volts on AUX1 and AUX2.
This allows to directly supply small external sensors directly by Photographer Tools.
The AUX1 and AUX2, you must use 3.5mm Stereo Jack male.
The tip of Jack is connected to + 5 Volts, the medium is the input signal, and the base is ground.
If you want, that your reflex triggers the "Photographer Tools", or if you want to trigger other
triggers for flash and one slave triggers, triggers the "Photographer Tools",
you will make the small adapter same as photo04.
It takes a single resistor of 100 Ohms.
It is possible to put this resistance directly into the cap of the jack, it helps to a single cable.
I did some tests, with a flash shoe on my DSLR, and with this adapter (new cable)
connected to the "Photographer Tools".
On OUT1, I put a flash and I was able to exceed the flash sync with my Nikon D90.
The Nikon D90 has a flash sync at 1/200s max, and I managed to shoot at 1/250s
without seeing black bars caused by the descent of the curtain.

So for the moment, this is the two adapters that can be helpful.
