Cart works fine with Internet Explorer 11. The assembled unit is on the same page as the kit but here's the direct link...

Indeed! It was not showing with Firefox :|

I ordered the unit and the probe, thanks!

Mark, did you ever get this resolved?

Slucky,

No I messed around with that thing, It's in that adjustment pot, cleaned up any solder inspected well but intermittent at best.

Through it off to the side for now, but thank you.

I received it today. There was even a 1x-10x probe inside the (sealed) box.

Just one more question: how stable should the 9V power supply be? I have a rather poorly filtered 9V power supply and I am hesitating at using it for the scope.

No idea. I have been using a 9v battery!

Get a 7809 regulator IC. Don't exceed 10V to the scope. I have a "9VDC" wallwart that puts out 14vdc unloaded. I put a 7809 on it. Two 9 volt batteries will probably last long enough for you to get tired of playing with it. :mrgreen:

You could use a OneSpot, like you use with pedals. Super clean 9.5v.

How long did it take for your orders to arrive? I ordered several items over two weeks ago, still waiting.
Thanks,
Greg

Thanks! If the battery lasts long enough before I order a 7089, that would be nice. I have 5 and 12V regulators but no 9. "C'est la vie" :wink:

Note that the power supply jack should have its center positive, so a pedalboard power supply might not be a plug and play solution.

Maybe this is a reason for prefering the kit version: it's easier to mod it.

It took 2 weeks and 4 days to arrive. I could read banggood stores items in the US, so the US guys might not wait that long. I am still waiting for the (redundant) probe to arrive, though.

But where are you from? It seems that the storm damaged many shipping containers in Germany. I hope that our goods were not inside but some should be impacted, at one point.

xtain, thanks for the suggestion on the $20 oscilloscope!

I spent the better part of Saturday assembling mine. It works, fits in the case, and the measurements ON/OFF feature is amazing.

Thank you, all who responded to my shipping time question. Still no delivery, so I will get in touch with them.
