Your content on Ltspice is one of the best out there. Please keep uploading new videos on the above topic. Also some content on embedded systems and analog electronic along with projects done on software's like Proteus and Ltspice will be highly appreciated.
Hello Grimm619! Thank you for the kind words! Well LTspice stuff will continue, among other more practical videos - but only as often as much as time allows. I'm not sure about Proteus though - I tried it out many years ago but if I was not extremely impressed, although LT has a more spartan look, once you get the hang of it its quite easy to use.
@@FesZElectronics thanks for replying. I highly agree with your point that Ltspice is a very powerful and useful tool when it comes to spice simulators. Although simulating complex models like a motor or some other inductive loads can become challenging and sometimes a pain and that's where proteus comes into picture. That being said your further Ltspice content will highly be appreciated.
Nice simple design. Professional probes with a hall effect sensor also have this effect with magnets, typically you can do a 'degauss' compensation to remove the offset.
I'm not sure if the degauss option refers to external magnetic fields, but rather the magnetization of the probe its self - usually you have a clamp made from ferro-magnetic material that can remain slightly magnetized when exposed to magnetic fields. This sort of magnetizable material is not present in the hall sensor IC that I used.
I haven't got into current sensing yet. However, I have been researching magnetic fields. If that device is literally a hall sensor > I'd be wondering how measurements turn out when multiple paths exist within the same area, b/c mag fields easily combine & cancel. eg, if you had 2 adjacent wires with different current&voltage, OR if the signals were in different phases OR had different frequency components. Personally if I were trying to get accurate and beat those cheap chinese things with the 7 segments already attached which are $5-$10 >> I would start with a slip over CT, OR something like a bridge(make it mini though!!). Those tektronix probes look nice, but they're $$$$$ .. It would awesome to DIY some current probes !! I salute you !! Why not try a more inductive approach. I know old school tape heads have an extremely short throw/HIGHLY directional. I don't think they pickup much even an inch away. All things considered / from what I gather from current technologies >> the series type are king . Just my $.02 . luv the content
I am noobie here , and I am looking forward to build this DIY while I am curios how would you calculate the bandwidth of a current probe and what would be the bandwidth of this probe?
There's this guy named bordodynov who has created an extensive list of components and libraries for ltspice which if figured out how to use them properly can prove to be highly beneficial and useful. Please consider this
Thank you for this suggestion! I did find his stuff and there is a lot of it, I will have a look to see the best parts. Anyway the next LT video I plan is about verifying spice models so in a way it is related to this subject.
I think that sensor's zero is not absoulte value, it is some ratio from your VCC. For example, 0 is not alway 2.499, it is more like 0,498 * Vcc. So, if this is correct, having some ratio from VCC for correction could be better choice. But I am not 100% sure if my assumption is correct. Most such sensors are having ratio from VCC as zero, not constant voltage.
Hi, I'm going to build this probe just one question, you and the datasheet are using an inverter amplifier configuration instead of a typical amplifier, is there a problem using a typical amplifier?, I tested this on ltspice and if I'm not mistaken works as well without the problem of returning an inverted signal, so don't get why the inverter config.
With the inverted configuration, the reference voltage is directly connected to one of the amplifiers inputs - there is no current to change the offset value; if you are using a non-inverting configuration, the reference voltage node is where you will also connect the amplifiers resistor network - you can end up changing the value of the reference depending on the input signal. With the right choice of resistors it might still work, although you can simply use 2 op-amps (double opamp in a single package) and re-invert the signal, to finally have the right side up.
@@FesZElectronics forget kicad, i used it for 6 years and i already switch to circuit maker, is a free-maker version from altium... Its the best free tool i tested
I guess the same will go regarding PCB software as for Circuit simulators - the best is the one that you know how to properly use. All programs have bugs, its just knowing the best way around them. I don't use Eagle because I consider it the best, I use it because I got used to all its quirks and it gets the job done for my needs.
21:09 I am glad you came to your senses. I was about to call the bench equipment distress line ;-)

Just found this channel, awesome content. keep up the good work.
I'm happy you like it! Thanks for the support!

@@FesZElectronics Hmm, good point indeed. So not completely comparable then.
Useful project! Thanks!
Cool! Do some more LTspice series on Gilbert cell multiplier or in general some circuits from designing to simulation
I will try to make more LTspice stuff in the future. Thanks for the suggestion on the Gilber cell!

Nice. Can you make a video or notes on the power signal ampflier box you made?
Your contents are Great . keep it up

11:59 Better to add a Zener diode, to stabilize the reference voltage for the bias adjustment pot.

@@FesZElectronics Thanks!.
At 22:00 seriously, set the trigger properly....
Whats the program your using? Isnt ltspice, rigth?
Yes. That is the program that I use for circuit simulation in all of my videos.
@@FesZElectronics i mean for the pcb
For that I use an antique version of Eagle. I do hear that Kicad is a really good free alternative though.
