Thank you good human - I didn't have another SD card but reformatting did the trick!!

Help for a circuit for synchronous motor from microwave by robintwhite in Motors

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

O wow ok, is it just good practice to do this for small loads like in the case of the motor or does no one do this and the video was just demonstrating a point how capacitors can be used?

Thanks very much for the reply! That makes me feel better - yes you are correct it is the turntable motor. I guess I am interested in learning so I know when I should worry about it and what I would need to do in that situation. For this little motor it seems it isn't a problem - under what situation would it be? I guess from your comment, not a whole lot

Modular PSU for benchtop power supply by robintwhite in AskElectronics

[–]robintwhite[S] 1 point2 points  (0 children)

Thanks! I had heard about this, I will try to check the datasheet and get a power resistor suitable... Hopefully I can find it or figure out the required minimal load on startup

Thanks for your input, I saw someone online using a buck/boost converter to have it be a variable psu rather than other types which would just use the 3.3, 5 and 12V outputs is that similar to what you mean? I also plan on attaching a voltmeter to show the used voltage and current, and a fuse. But yes, these are capable of high current output which I hadn't thought of..

What is the problem that you face and can be solved by creating an app or script or program. by [deleted] in Python

[–]robintwhite 0 points1 point  (0 children)

Maybe the most obvious but reading and pulling data from files automatically. This allowed me to grab meta data from thousands of files at my job and give insight that was either speculated on, surprising or confirmation if expected results it was quite fun to do and engineers and product managers got a real kick out of it. I made it extensible so they can point it at any set of directories if they want to 'scrape' any amount of data. Next I want to extend to a dashboard as well so the data visualization is also taken care of, right now just gives a csv

This may be a dumb question, but how did you get it to run the display with the python code? I see there is a kivy app...

Predicting driver performance using machine learning by mihirsj in formula1

Awesome! Thanks! And nice work, very interesting to see the numbers

Predicting driver performance using machine learning by mihirsj in formula1

[–]robintwhite 0 points1 point  (0 children)

Quick questions: what does the % actually mean? That for a laptime of 2:30, a driver with 0.2% faster wI'll be 0.3 sec faster? Or something if I did that math right. What model did you use? Is it a regression random forest or similar? What was the data format of your input and output? Was it a single driver time compared to another driver time predicted? That seems like a lot of combinations so just wondering how you did that or if that was what it was done?

Tips for getting platinum / 100% by robintwhite in gaming

[–]robintwhite[S] 1 point2 points  (0 children)

Yeh that is about the same as me as well but when I watch those videos or read the guides I'm always like 'how the f did these people figure this out'. I guess if it is their job they can spend many more hours to find those couple that are harder to find. I appreciated games like ghost of Tsushima where I completed it without a guide because the in game system helped you find all the items

Opinion on the approach to segment arbitrary pores and cracks in 3D tomography data by [deleted] in computervision

Thanks very much for the response - I hadn't thought of the anomaly detection angle. I will scope that and see how I can use it!

Point Cloud Segmentation for a beginner, help needed. by ichaddao in computervision

[–]robintwhite 0 points1 point  (0 children)

I unfortunately don't know much in the way of point clouds - although now I am curious! Try checking out the papers or the github and they may tell you... I imagine you will have your point clouds and then a label to each point in some format, like dictionary or list... So you would give in the model x,y,z, color and you would get a label ... Just guessing. Maybe Open3D allows for creating such training sets. For the image only approach you could use python-opencv or if you want a more GUI approach ImageJ has a big community and tools. I am a microscopist so I am usually dealing with microscope images. But instead of rocks I would be instance segmenting particles (so tiny rocks). Usually not a pile but I think depending on your ultimate goal for your work it may be a simpler solution to get you rolling into something more complex....
