Skeptical Boost polarity

[mcluff]

Hey all -- I'm about done with my Skeptical Boost but I noticed that the 9V input spots on the PCB are marked "~ ~" instead of the usual "+ -"

I'm assuming it should be + on left, - on right (looking at the printed side) like usual. Is that right?

The input has a bridge rectifier into a voltage regulator into a dc-to-dc converter. It’s polarity agnostic and can accept AC or DC input (7.5V – 24V).

Oh derp, of course! Thank you

Please excuse my ignorance. Does this mean I can hook it up the positive and negative to either of the ~ ~? In other words, does it matter which ~ the positive goes in, as long as the negative goes in the other ~? Looking at the schematic, it sort of appears that way. Thank you kindly.

That’s correct. It doesn’t matter how it’s connected.

Did yours work? I cannot get mine to boost

Never got mine to work! Haven't done a full troubleshoot yet but I'm considering starting again with it?

I’ve built two, both work great.
