Gary over at TOG-Dublin Hackerspace published a new build, the vintage metal detector project:
ETI Electronics, February 1978, IB Metal detector Mk2. This is the first in a series of ‘vintage’ electronics projects that we hope to build at TOG. We have the original magazine, so why not get building. There are some amazing projects in the electronics magazines from the 70’s and 80’s.
Update…. The build is in progress. Pics here.
