Hi FvM thanks you for the response. I haven't measured the amperage, I'll do it next time I tinker with it, I'm working in the software side now trying to find out the better way to implement it, I'm not sure if its better to go for a lower PWM period. 500 ms seems to work better and the trials...
Hello everyone...
I have this temperature controller in my basement that I designed, its an NodeMCU board ( ESP8266 Wifi module ) that I program with the Arduino software. The controller has temperature probes and controls an inline duct fan similar to the one in this picture:
The...
Thank you for all the replies, I'm sorry we didnt have internet at the farm for several days due to a storm that damaged the antenna. I forgot to mention this farm is located in the souther mexican pacific.
So the discrepancy I see is due to the Power Factor from what I understood from the...
I work on a shrimp farm as an electronics engineer, I dont have a lot of experience in power electronics, just wiring three phase motors required by the farm as aerators.
We have a big diesel generator 100 KW of power, today the grid went out and the gen kicked in, after all motors were back...
I need to switch a 20A 240 Volts load, I have a relay rated 40A with just 4 terminals, the 2 for switching on the relay and the others 2 a NO contact, so my question is if its OK to switch a 2 phase load by switching off just one of phase or should I use 2 relays and switch both phases.
I was wondering if anyone knew about a circuit to generate coloidal silver. I know it is asy to generate it but haven't found a really nice circuit. For example some sites advise to reverse the positiv and negative terminals every now and then, and would be nice to have some kind of meter to...

Thank you guys for all the responses, I had so many problems with interference in the input stage at high frequencies... I was really getting close to something workable when I found an old used 20 Mhz Scope for les than 100 usd, I just went ahead and bought it...

Ok I figured out, I can't belive I spent so many hours on this stupid thing, I never thought you had to drag the device from the tree view to the library manager. I have another question: it is possible to change the name of a device inside my library (For example from...

I'm using version 4.16 but kept the discrete library because thats exactly what I use the most, I just want to add some devices to that library and use it as my standart library for proyects.
The problem is that when I do as you said the options Copy to Library and Add to...

Thanks for the help. I have been using Eagle for a while and I'm pretty happy with it, also you can't beat the price beeing free...
Well the only problem I have so far is: I'd like to create a library of favourite components, in most of my proyects I use the...
I like sleeping with the ceiling fan on, the problem is that at night is very hot when I go to bed so I turn it on at max speed. Early in the morning the temperature goes down a bit so I have to go out of bed to turn the fan to a lower setting. Is there a circuit to control the fan so it runs...
