High voltage on flash hot shoe? An insert between camera and OLD flashgun.
Step 1: Circuit
Well, it is not new idea. It is not a patent.
It is common principle how a thyristor works.
Step 2: Parts From Scrap
Left is a shoe from old broken flash - unscrewed and right is part form disposable camera, just cut it of ...
Step 3: Insert
All parts together.
I made from Plexiglas an insert, thickness about 35x30x8 mm, and carved proper extension slots..
Step 4: Lower Part
Of course, different extension slot for lower shoe...
Step 5: Upper Part
Upper part have a different print so the extension slot has to be made different way...
Step 6: Testing
On paper was all OK, but now a real situation...to adjust components.
Step 7: Works or Not?
This is when I use original voltage from flash... Red wire to touch a gate ... it works!
Step 8: Before Assembling
Final testing before assembling and gluing...
Step 9: Squash
Trickiest part of all. Put everything inside...
Step 10: Before Gluing
And now only to apply few drops of Cianacrylat glue (fast glue)...
Step 11: Left Wiev
Assembled. Stitched on. Ready. Go.
Step 12: Right Wiev
Well, so I made it. I can put any old flash now on and under I have a low voltage.
It works for me.
You can do this on different way. Different form. Different results.
Remember, what you do- it on you own risk.
