Query: A wire chamber for educational purposes   Gaseous detectors with sense wires are still in use today in small
experiments as well as modern ones as those at the LHC. This short note is
about the construction of a small wire chamber with limited resources, which
could be used both as an educational tool and also as a tracker in small
experiments. The particular detector type selected for this work is the so
called "Delay Wire Chamber": it has only two output channels per plane and can
be made fully gas tight for educational operations. The design can be made with
free software tools, and the construction can be achieved by relatively simple
means.
