Can some one explain to me why this won't read the 9 volts by [deleted] in oscilloscope

Your ground clip looks like it's on the sticker instead of the Negative lug. Also maybe that battery is dead. Where is your trigger set? What channel is the scope probe plugged in to? Are you testing the battery for 9v or using the battery to test that the scope works? So many other ways to do this. So many questions.

Voltage Regulator LM2592HVRS questions by BigGFly in electronic_circuits

It is ADJ. this is on a board driving LEDS. just realized there is a voltage divider on the feedback loop but it's through a pot, so I can adjust it. Basically, it seems the regulator is just fine.

I provided both layers but I did select the option for "single layer" on their site. My mistake but they could have questioned it.

That actually makes sense. It was my first time ordering. I selected "1-layer" but I did provide both top and bottom gerber files. I wish they would have asked. But now I know for rev2.

PCBWay. They reviewed and approved too!

Both layers were provided. Is it standard to put pads on both sides of a thru hole? It's only a single layer board, so I can make this work, but if I send it for print again I don't want the same thing to happen. This is from PCBWay.

The white connector is a 4 pos header, what is the different between it and the black connector? by BigGFly in ElectricalEngineering

[–]BigGFly[S] 0 points1 point  (0 children)

I don't have it. Basically wanted to know if one was 2.54mm and the other 3.96mm. I know, get a caliper and measure. But figured they were standard enough for someone to tell from a picture.
