AC-AC & AC-DC Power Adapter Tester
Sure, that 50-cents non-returnable AC power adapter you found in the Unlabeled/NoWarranty/NoNothing bin the local thrift shop is a bargain and defeats any effort at building your own small power supply, but R U sure it’s the right voltage-out? And what’s the plug polarity, and the spec on current-out? Who knows it may even be AC-out.

Gerber file

CAM/CAD data for the PCB referred to in this article is available as a Gerber file. Elektor Members can exclusively download these files for free as part of their Membership. Gerber files allow a PCB to be produced on an appropriate device available locally, or through an online PCB manufacturing service. Elektor recommends its business partner Eurocircuits as the company of choice for its own prototypes and volume production in selected cases.

Download the BOM list
The BOM (Bill of Materials) is the technically exhaustive listing of parts and other hardware items used to produce the working and tested prototype of any Elektor Labs project. The BOM file contains deeper information than the Component List published for the same project in Elektor Magazine. If required the BOM gets updated directly by our lab engineers. As a reader, you can download the list here.
