This is a modified version of G0MJW's modified version of Kozon's Power supply box for DDS signal generator. I removed the screw holes because two of them never lined up on either of the predecessor designs, and since the PCB and cover snap nice and snugly together, additional hardware seemed superfluous. I reused the vent grill that G0MJW put on the bottom of the case on the top portion. As G0MJW points out, heat dissipation is often better and more desirable on the ground plane for SMD components, but this particular PCB design aimed for simplicity, so any improvements gained by attaching syncs to the bottom of the board are likely lost in poor surface contact with imperfect solder pools and the fact that heat rises. Still, I left the depth of the base and vent grill of the base unmodified from G0MJW's improved design. To the top portion of the case, I added a large access area for the screw terminals and header connections as well as a hole for the incoming power LED. Additionally, I shaved plastic from the inside of the feet that partially obstructed the last screw terminal on either side of the PCB. On both top and bottom, I widened the opening for the incoming power barrel connector as this connector was partially blocked on my PCB. The access modifications are unnecessary if you use this PCB exclusively for the function generator it's most frequently sold to accommodate, however, I find this unit to be extremely handy for powering all kinds of project circuits, so access to the screw terminals and pin headers are quite helpful. I'd like to thank Kozon for his original design, and G0MJW for his improvements. Hopefully somebody will find these further adaptations useful. 07302020 Added version 2 of this box. Version 2 has a shorter top and bottom half to reduce the overall assembled profile of the unit. Version 2 also has all beveled edges and modified power input openings that are a closer match to the board locations and size of the respective connectors. While I left the bottom vent openings, version 2 no longer supports bottom mounted heatsyncs. If you assembled the unit as designed and per instructions, the board should fit properly. I left the version 1 files here. The version 2 files are labeled as such.
