Well, if the switch turns on when the AC is at a peak voltage, the dV/dT will be VERY large. xC will be very low as a result. Donald.

Not directly electronics but many in the electronics world use 900MHz devices for all sorts of applications. As a license free band, it's attractive for experimental remote control, remote monitoring

Hum. Never considered that, I don't doubt you but will the instanious current ever exceed the Xc? It feels like the maximum current can't exceed the Xc.....and yea feelings are important but

One more detail: You previously mentioned that you replaced the resistor with a fuse. You ought to have a small value resistor there. If the power is switched on at the peak of the sine wave, an

I made a mistake, in my description of a ultra simple current limited LED driver. Call the cyber police to take my PCs from me. [Me making a mistake ought to make at least one person in this group

I checked with the KY DOT and our MD before using it while driving and there is no comment, good or bad, about using a nebulizer while driving, the rules concern what is being vaporized. Albuteral is

Hi, Actually I was more interested in this new way of quickly diagnosing car problem using something called “pressure pulse sensor” : <https://www.youtube.com/watch?v=6CcYPhtfKSk>

I have that model. Amazing performance for the price. I seldom use it since I have regular bench oscilloscopes except for when there is no power available or I do not want the headache of moving a

I was looking at Hantek. Their 8 channel would be sweet but sampling falls off quickly and also appears to be geared around automotive environments. ~SD

Intended purpose is to look at waveforms / triggers of IGBT and their drivers on a 118KW aux pwr supply fed by 800vdc. Cost is a factor, I can see losing an IGBT & Driver violently and taking out

Read the reviews. Not the best out there. This is a good start to at least look at waveforms, but most negative reviews says the calibration is not good. There is the PoScope version that is USB based

Depending on what you intend to do with it, can be a good choice or not. From my experience, if it's just for occasional DIY or the like, it's good enough. If you want something slightly better, WITH

Been kicking around idea of getting a pc based o-scope to keep in my tool box. My first ever was one that connected to a SoundBlaster Pro sound card. Have had a few over the years (portable pc based).

Yup. ~SD

Nope, not something that can be used while driving. Or shouldn't be used. Mine was battery portable, the Nickel something battery having short life span during treatment. I dont think it heated. I

Oh, for the record, I've never claimed to be responsible, only mostly accurate.
