Dave looks like a double oven reflow job, they might have placed the passives first. It just looks like the passives drifted off their pad a bit, and then the actives were put down. You can see a lot of bubbling in the solder joint. Anyways you were showing a bunch of inductors in a group time 9:39 that might indicate config options. But to me they would just change the DAC board in front to change the instrument frequency. Well Dave totally COOL review of a product, nice in and out shot. 4k review might have to wait for some of us to see. But keep your electrons flowing and don't get shorted Cheers.

Dave,I know it is off topic, but a video that I would LOVE to see you do is a full length tutorial on repairing zebra strips on meters.I have done a couple, and turned them from faded to brand new. But I have one more to do, and I know that it doesn't always work to just clean the edge of the strip.I also have a calculator to do.Aside from cleaning the edge with alchohol, has anybody ever tried "shaving" the edge with a scalpel or sharp razor blade just by a "knat's balls hair", as you would say? Obviously it would have to be a VERY tiny sliver that would be removed, otherwise you would have to shim the presure on the zebra slightly.What do you think? Think about all the tech's out there who could benefit from learning out how to bring zebra strips (and hence meters) back to life!All the best....

Spending something like 30 seconds to show what it looks like when turned on would not degrade the quality of the video, but the exact opposite. And nobody would certainly complain about it. Seeing how the device looks when turned on would be interesting to a casual viewer. It would not turn away pros. So what exactly is the harm? (And cue people defending the practice, with zero rational reasoning why.)

So if this processor on this generator can support Android and Linux, then what OS does it have on it to begin with, and how and why would you change the OS anyway? It's proprietary, right? So what would you do with other OSes replacing that? Or does it support those OSes just because it's a somewhat common processor like the Motorola 68K series and the Intel series and compatibles (and even the MOS 65xx/85xx series), and we might see one in many tablets and phones? But even if that's the case, then still, what OS does this run on?

Someone make a circuit that can calculate the speed of a bicycle. What I have in mind is a magnet on the bike's wheel that will pass a coil and create a pulse of electric current. Then have a circuit count the time frame in between the pulses then do calculations based on the wheels circumference to find out the bikes speed. This will be displayed on a 2 digit 7-seg display. Too bad I don't understand electronics enough to create these kind of complicated circuits. Maybe someone out there can apply my idea. Or maybe it has already been done. Thank you.
