How to make coolpix 775 work with a Slave Flash and other things?

DrXu.com viewer Laureano López has come up with an original and fantastic schematic to make coolpix 775 work with a Slave Flash. Below is the schematic and a sample photo.

Laureano would like to share his experience with all DrXu.com viewers. Below is the message he sent to me:

"I love  to experiment with digital Photograph . Trying to use a slave flash I found that it don`t lit at the correct
time.To resolve this problem I has make a very simple delayer circuit and now theslave flash works fine and it`s very easy to take photos really wonderful.

I wish to share this experiencie with other members that can be interested on it. If you want to put it on your web, I can give you the schematics and some photos about the construction of this device. The attached file is sample of the photos that we can take with this device.Also I have interesting things about Infrared Photos and amazing pictures of
moon fixing the camera and binoculars to the same tripod. Please, excuse my bad english.

Congratulations for your nice web."
