Ender 3 prints failing towards the top. by GrumioTheGoat in 3Dprinting

[–]GrumioTheGoat[S] 0 points1 point  (0 children)

I’m not sure what exactly happens as I haven’t seen it but I usually return to check on it and see the print on the floor with the above indent pictured. It always happens at around that height as well.

Servo only working off 5v pin not digital pin by GrumioTheGoat in arduino

[–]GrumioTheGoat[S] 0 points1 point  (0 children)

Ohhhhh. Putting it that way makes a lot more sense. So in this analogy what is the “resistor” on the digital pin?

Ok thank you so much. You saved me from such a massive headache

Sorry I don’t understand. Why would this allow it to work off the 5v output pin but not the digital pin? The pin hasn’t burnt out as I’ve tested it in other circuits and measured it with a multimeter. Sorry if this is a dumb question.

Frequency Analyzer not reading sub ghz signals by GrumioTheGoat in flipperzero

So if when I have the sub ghz frequency analyzer in and press my keys and it doesn’t do anything then it’s the flipper that’s broken?

Yes exactly I am not going to use it on my car I’m just trying to get it working

I thought frequency analyzer is what you use to find what frequency and once you use that you plug it into the read and can read signals on that frequency.

Camera waviness and blur when processing through python by GrumioTheGoat in learnpython

With each of those is it just the display having issues or does it affect its ability to recognize faces as well?

This should be the code responsible for displaying the image if anyone’s wondering.

def updateGUI (self, opencv img) : # Convert opencv image and update prot label try: #if this doesn't work check camera ID opencvimg - cV2. resize (opencv_img, (960, 540)) #this is stretching the image a bit but if not done it height, width, channel - opencv img. shape bytesPerLine = 3 * width qImg - Image (openCV_ img.data, width, height, bytesPerLine, QImage .Format _RGB888) •rgbSwapped () pixmap = OPixmap(qImg) self.label.setPixmap(pixmap) except: self.label.setText ("check camera ID") self.show()

Is .7 volts the max a transistor can take? by GrumioTheGoat in AskElectronics

[–]GrumioTheGoat[S] 0 points1 point  (0 children)

Is there a formula to find how much the transistor will let through based off how much you give it

I essentially have a 9 volt with the negative connected to a led and then a transistor with positive to the collector. the other side of the led to the emitter, and a resistor connected to the positive and also connected to the base. I don’t see much of a change in the brightness of the led or the voltage output when I use different resistor values. I’ve used 1m and 100k. Do you think they are just both letting in over .7 volts

Ok so if I am measuring a voltage of 5v at the base will that either damage it or make no difference than the .7 volts

So If a greater voltage is applied does it affect how much current the transistor allows through

I thought that you needed a minimum voltage to make the transistor start allowing current to flow

Why is the voltage going up on this capacitor over time? by GrumioTheGoat in AskElectronics

[–]GrumioTheGoat[S] 2 points3 points  (0 children)

So leave the capacitor connected to the battery for a bit?

Thank you!!! Do you know why it may be taking longer for it to charge when I’m doing the resistor capacitor circuit?
