3D-Reconstruction: Building a small, simple Turntable [Video]

Sep 1, 2024

in 3D Reconstruction, Projects

In this video we’re building a small and simple turntable that we can use to take photos of an object in regular intervals. By combining the turntable with gphoto2 most of the process happens automatically. This is the second post in a series about 3D Reconstructions. The first post gave an overview of what we’re…
3D Reconstruction: Intro and Image Acquisition [Video]

in 3D Reconstruction, Projects

This is the first video of a series about 3D Reconstructions. We’ll use the open-source Photogrammetry program Meshroom and a home-built machine to take pictures of an object in regular intervals. Over the entire series we’ll look at and test which factors affect the quality of our reconstruction. I’ve found 3D reconstructions fascinating for a…
Building a DIY Spectroscope [Video]

in Projects

In this post we’ll use a camera, an analogue pocket spectroscope and some software that I wrote to build a digital spectroscope. The spectroscope will be limited to roughly the visible range of light (~400nm to ~700nm). While it’s probably not as accurate as commercial devices we will calibrate it carefully to give decent results.

In this video we start a journey through the history of human ideas about the nature of light. It’s a long journey but we’ll try to keep it brief and concise. In this first part we focus on Europe and on the Middle East. In future posts we’ll move on to the time from 16h…
Mono-Conversion of a Canon 350D [Video]

in Photography, Projects

In this video we disassemble a Canon 350D and we remove the top layer of the sensor, which includes the colour filter array. As a result we’ll end up with a monochrome camera. We also discuss auto focus calibration and a few related topics.
RPi NAS: Extras – Building a Case [Video]

in Linux, Projects

In the previous posts we covered the hardware related aspects that matter for this NAS, now we can finally set up our system! This post contains a video that goes through the process of setting up a Raspberry Pi and installing and configuring Greyhole. Setting up the NAS involves a lot of steps, which are…
Snapper Rollback on Arch Linux [Video]

Jul 7, 2023

in Linux

Linux allows for an enormous amount of customization and control over your system. But if you’re not careful then it’s very easy to break it in some way or another. Rather than trying to undo a mistake, it’s often easier to just wipe the slate and start again. One way of achieving this is by…
