The EZTube Lunch Box design is now advanced enough to make it available to the DIY community. All the power supply and enclosure issues have now been resolved and the majority of the documentation is complete. An overview of the Lunch Box Project is given in the following document:
Lunchbox User Manual
This document describes the overall objectives of the project, and top level constructional information including the enclosure alternatives and basic module mechanics. It also lists all the other documents related to the Lunch Box project.
There are now four power supply PCB options, two with dc heaters and two with ac heaters. One dc heaters power supply is for use solely with an external power supply and the other one is on a standard Eurocard that plugs directly into the backplane. One of the dc heaters power supplies is the 100mm by 100mm PCB intended solely for use in Frank Rollen's enclosure. The other dc power supply PCB is Eurocard sized and plugs directly into the back plane. All four power supply PCBs are covered in a single document that can be found here:
