With Frank's blessing, I have seven of his version 1 (25x100mm) PCBs available. $40 each includes USPS shipping in the US. These are fully assembled and the pots are pre-trimmed, so they will drop into place and work right out of the box. Email me (PMs kill kittens) if you'd like one.

<p>Necro bump for help. </p><p>I'm assembling a v1 board right now. And just tested it. Adjusting the pot lets me change the switchover up to like 13.8 volts. and then as soon as I adjust it anymore, it won't switchover at all.</p><p>I'll try and post a video.</p>

<p>Update.</p><p>Here is where I'm at.</p><p>I turn the voltage up to 14.5. Field voltage stays ~14. Turn off the power supply, field voltage is at 0. Turn down the voltage to 14.4 or 3 and the field voltage goes back up.</p><p>Its like it isn't switching correctly.</p>

<p>Update.</p><p>If I slowly change the input voltage then I have to go all the way up to ~17 volts for field to drop to zero.</p><p>If I raise it quickly straight to ~14.7 or so then it drops to zero.</p><p>When I slowly raise it to ~16 field reads 14.8.</p>
