That's what I use in all my calipers and micrometers. The difference is that the SR44 cell uses a silver oxide chemistry while the LR44s are alkaline chemistry. The SR44's discharge curve is also a lot flatter, so with a slightly higher starting voltage the SR44s consequently lasts a lot longer.<p>-=- Terence</p><p>http://blog.OpenBeamUSA.com</p></p>

Which is correct?</p>

That outputs 'only' 277oz/in of torque and I have ripped the stock Axial mounts to pieces in a hard steering bind. These little beams simply do not look strong enough for that. On go-fast RC cars like my Slash, I have hit hard enough to dislodge bullet connectors and servo tape, these would snap. Granted, im hard on my stuff, but still.<p>Id assume this mount is for light duty stuff, looks like itd work admirably for that.</p></p>

Rob's not trying to mislead anyone, though, these are just usually improvised one-take videos and he's not an engineer (nor am I). He stays plenty busy keeping the catalog in order. Thanks for pointing out that mistake so no newbies get the wrong idea. We'll try to be more careful in the future. Thanks DanJAB!</p>

In this case, the inverter puts out a higher voltage than the input, but it's main function is the frequency generation, not the voltage difference.</p>

Though maybe this would be fixed more simply by having a QC that checks the inverter with the board (both output wires are black, so it can be super confusing).</p>

Quote from the video starting at 6:13 "An inverter simply takes one voltage and puts out a much higher voltage" NOT NECESSARILY TRUE. An inverter takes a DC voltage and outputs an AC voltage.<p>Yes, in most cases it is a higher AC voltage output than DC input but an inverter could give out a lower voltage than is going in.</p><p>I don't want to be pedantic but it sounded like you suggested that any high voltage will do, what's more important is actually that it is AC as DC will not light EL wire (not constantly anyway).</p><p>Maybe I am being pedantic but anyway...</p></p>
