Welcome to Issue 10,
Thank you to all of you who have ordered volume one (issues 1-8). After some printing delays the cordex binder for volume 1 has been submitted for rapid production. The final pdf files needed for printing each of the magazines are nearing completion. We expect to be releasing PDFs for printing this week. We are very grateful for your continued patience. Such delays are not expected with volume 2, since all of the articles are already in the correct format for printing.
In this month’s issue there is a great selection of hardware and software projects.

We are on the look out for willing volunteers to help with layout, testing and proof reading activities. If you can dedicate some time, please email firstname.lastname@example.org.
