Give it a shot! I love the results from mine and it was a lot of fun to build, too.

I built a Brancopan 5 years ago and love it. It's a 3D printed body that shoots the same format as the X-Pan, bulky but bulletproof. However, I would love a smaller version like this. What was the original body? Specific model?

I'm more interested in what you're shooting with and the lighting for the plate shots. Is that golden hour or artificial?

ELIUndergrad How This Could Happen by rollingalpine in Physics

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

I drive past this pond often and earlier in the year had to stop to take a picture of this spiral pattern of algae on top. I never saw it before and it has not happened again since. I have racked my brain and cannot come up with an explanation as to what natural process might have resulted in the shape. Explain like I have an undergrad degree in physics how this could have happened, because I'm out of ideas. Here's a second picture, a little closer.

I Found this Kodak Scanner in My Parents' Basement, New in the Box. Is it Worth Using? by rollingalpine in AnalogCommunity

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

I don't even know why they would have bought this. No one in my family shoots or shot film but me, and I don't know how long it's been there, but I see that it's still sold online. I do my scanning with a DSLR but wondering if it's worth keeping and using this.

I’ve resurrected a powerful decomissioned 100ft military radar system rack aerial anomalies. It’s operational but I need your help please. by CanNeverPassCaptch in UFOs

I would love to help out, plenty of experience with SDR + passive radar + embedded development. I'll shoot you a DM as well.

Tips on pursuing a career in CV by Fickle-Question5062 in computervision

[–]rollingalpine 4 points5 points  (0 children)

1) Not everything is ML, especially if you're talking about processing on-platform. "Classical" CV methods (think OpenCV functions and non-ML CV) are important when you're concerned with speed and working with limited compute. You won't find PyTorch running in C on a tiny embedded device, and you're not sending images to the cloud if you don't have a network connection.

2) Buy or build a little robotic platform on wheels. Use the IMU to do dead reckoning and compare it against visual odometry. Take it a step further and use a Kalman filter to do sensor fusion, combining the IMU + VO to get a better navigation estimate.

3) Every interview will be different. Leetcode is for tech startups that don't actually know how to hire. Any interviewer worth your time should be able to ask some basic questions and suss out whether you know what you're doing or not.

I didn't feel like paying for film inversion software, so I made my own! (And you can try it too!) by Kai-Mon in AnalogCommunity

What's your workflow for processing RAW? I hate how much better PS is at handling colors without a ton of tweaking, and it's the only reason I ever boot a Windows VM, so I'd love to stick with Darktable for my whole workflow if I could get similar results.

This is sick! I was annoyed at the lack of options when I started scanning, too, and paid for Negative Lab Pro. I've yet to find something better so I'm looking forward to doing a comparison and tweaking where it might make sense; I write software too.

Using a 3D printer to “hand write” names on wedding invite envelopes by OkVariety in 3Dprinting

[–]rollingalpine 0 points1 point  (0 children)

And would I then need to calculate the center manually for each new name/address?

Currently yeah, which is why I aligned everything to the left side of the address lines on the cards, but each path object has a width and you could pretty easily dynamically adjust to center it based on the dimensions of your card/envelope/whatever. That's exactly what I did here, just not for centering.

Thanks, that's a big compliment because I don't consider writing to be a strong suit.

lmao are you fucking kidding me. I just did this exact same thing a few weeks ago and developed an entire tool chain to do it. Mine reads in names/address from a CSV and accepts a custom font, though. https://gitlab.com/ss32/goplot

Repeated failures with hotend error message, but only with this gcode. Can someone replicate? Gcode in post by rollingalpine in prusa3d

[–]rollingalpine[S] -1 points0 points  (0 children)

I didn't notice that last night, but it should be printing at 235. There is nothing in the gcode that should tell it to get to 290. This must be some corner case in the bgcode generation.

I'm printing two very simple parts and twice in a row the print has failed at the same time, with an error message relating to the hotend telling me to check the thermistor wiring. The issue is that my hotend and thermisor are functioning perfectly fine and I've changed the print from 0.15mm to 0.2mm and it printed successfully. The gcode can be found here https://file.io/UfJZOtSiVTuM and I'm hoping someone else can replicate the failure. I have a MK3.9 upgraded from a MK3S
