Per the Geofex website (regarding the Spyder power supply):
“April 10, 2015. This project has been up on geofex for fifteen years. I believe it was the origin for commercial many-output power supplies for pedalboards, and for the many dying battery simulators that are common in the DIY effects world. However, it does involve some risks. That warning is serious. In a couple of forums on the net I have seen some questions that have finally made me conclude that there are people coming into the DIY effects world that will ignore the warnings however they are worded. So, regretfully, I am removing the technical content from this article. “
