We hope to have some details here in a few weeks about the general purpose flash trigger circuit for starters.  If all goes well with it you should be able to build your own at our next Physics Alliance Meeting.  (No date yet but soon I hope!)
   Hopefully in time we can post other relatively simple projects here.  In the meantime if you're interested in things electronic, or your students are, please drop me a line by way of the email link on the home page and/or check out the series of books by Mr. Mimms carried by Radio Shack as well as other places.  If you want to see some of these books we also have a partial collection here in the physics department.
