If you have some old camera flashes in the closet that you can’t use with your new DSLR have a look at this project that Adapts an Old Silver Flash for use on a Digital SLR over at Rien que pour les yeux. There is a 5.1 volt zener diode in the circuit to protect the TTL fire circuit of your camera. Please follow the warning on the site that mentions the dangers of attaching an old flash without a converter to our modern camera which could cause permanent damage.
