A "Build-it" Printing Exposure Meter was described in Photography How-To Guide in 1978. it is simple to build, and back then used only $10 in parts. I built one and have used it for a number of years, until I replaced it with a commercial model. Included in the article are instructions to build as well as how to use. It is especially useful when making different size enlargements from the same negative. ...saves test strips.

Familiarity with small electronic parts and a 25 watt soldering iron is helpful.

I have the 13 page article now on a PDF file about 4mb size, and am willing to email it to anyone who asks. PM or email to:
