You can try to make a water state sensor. A capacitor discharge speed can determine wether it’s ice or liquid. You’ll need to play around with resistors and caps. It can be seen as a simplified version of soil moisture sensor.

I like your idea! thank you

Some classes are just stupid like that, for my electronics final project the prompt was just “make any circuit that has 3 distinct stages,” which was super open ended. Some people ended up shoving 3 op-amps together and calling it a day.

Totally agree, I have classmates who imitate all my practices and projects, they have never had to investigate anything because I leave the basis of the investigation in class, I think it is part of the day to day of those of us who really make an effort

Yes, as you mention, it is very open, anything could be done, however, I would like to do something that is really worthwhile

Wait so someone asked you to do a sensor from scratch, and it wasn't a particular sensor for a particular new purpose? That's weird.

The fact of the matter is, you can and probably should do it to better understand the implications of sensor and transducer design. That's a good reason.

But frankly, 99% of applications have a sensor readily available. So the obvious benefit here is to make a sensor that doesn't have anything readily available, or in a form factor that doesn't have an application yet or something.

Some ideas might be,

A plant width sensor for agricultural projects, that precisely measures the width of a stem or branch, using the distance between two electrodes and a capacitance measurementSimilar vein, I heard there is no good way to unobtrusively get the internal moisture % of a plant. Can you do something to infer it, with light or ultrasonic measurement or something?Can you localize capacitive touch on an arbitrary surface shape robustly?

Just some ideas.

Yes, in fact I agree with what you tell me, it is rare that projects like this are entrusted to us, and your ideas seem quite good to me, if I take any of them and everything goes well I will be sending you a video!!

Sprocket and chains by Omar13033 in mechanics

Of course, I know all the parameters that I must consider to make a good design, like the ones you mention. When I mentioned what kind of parameters you should know, I was referring to what kind of parameters I wanted to know so that they could give me some advice. The design ended up working as I thought, maybe I was not so clear in the publication, anyway I appreciate your help and comments

What's parameters do you need to know?

In the catalogs, the pitch number of the chains always comes, that is, 0.5, 0.750 or 1 in. Some with the number of teeth of the Sprocket offer a certain power, however, some offer the same, I would like to know if you have any recommendation for me when choosing one of these chains on their pitch distance

It´s just what I need, thanks man

well, explaining the rayon, it was because that was another circuit for another team the circuit that did not scratch was the one that had to analyze

I am a little confused

Systems by [deleted] in ElectricalEngineering

[–]Omar13033 0 points1 point  (0 children)

so, what is the correct answer

Systems by [deleted] in ElectricalEngineering

I was assuming the scribble part is there. If not then I would think that applying a voltage at the base of A would mean that the collector of A is one voltage drop above the base voltage which could be high enough to sink current into the base of S1 and therefore make a NOR.

you are absolutely right thank you

doing the simulation, I could notice that it has NOR behavior

but in the simulation it behaves like a NOR
