For portraiture and other special shooting modes using flash is often necessary in the illumination of the object with different angles, but Standard... "blitz" the desired effect, alas, does not.
We offer homemade device allows you to enable sync one camera not one, but two flashes (FV, FV), and this is achieved shadowless illumination captured on film objects.
Unlike previous surveys, where ignition of the lamp is a bright light source is supplied from the pulse transformer, the primary winding of which discharged (via the sync IC camera) bolsheselsky capacitor, here, an additional already attracted a pair of thyristors.
Part of the discharge current of the capacitors of the camera flashes through the diodes galvanic junction VD1 and VD2, vicious sync IC and the limiting resistors R1 and R2 is supplied to the control electrodes of the thyristors VS1 and VS2. Button SB1 is to reset the charge, if the subject did not take place.
A circuit diagram of the device is so simple that collect it can pretty quickly even new to electro - and radio engineering. Besides and radio component this requires a little, and they are all inexpensive and available. Mounting - hinged, familiar to everyone from school physics lessons. And as the case plastic box size 50x40x30 mm.
Basic electric circuit device to include two "blitzes" from microcontact one camera
After the first response, followed by the regular ignition on display the flash device is ready to use for the scene.
