Best of first 180 stereo photos

Today, I present you what I think are the best of my first 180 stereo photographs. All images shown here are made with a simple compact camera without any further equipment, using the so-called cha-cha method. It means taking two consecutive photos from slightly different positions.
I recommend to set your preferred view below the first image and to reload the page by pressing F5. You can also view the album on Phereo.

Homemade weighing scale - Calibration and readout scale

This post helps you to calibrate your homemade weighing scale and creates a printable readout scale that you can glue onto the device. The post will guide you through the entire calibration process, establish a functional relation between mass and indicator position (the process is termed regression), and lets you configure the appearance of the scale. Finally, you obtain a file that you can print on a black/white printer.

To allow you reading through the page and trying out the tools without doing the calibration, I provide example data from my prototype weighing scale.

Homemade weighing scale - Construction and Plans

This post provides a tutorial and plans for a homemade weighing scale, similar to a classical letter scale. You obtain a scale that you can easily adjust to have the range of your needs, be it for only 20 grams like my prototype shown on the left, or for 100 or 200 grams.
Accompanying this post, I provide a tutorial and JavaScript tool that allows you to easily calibrate the weighing scale and that produces a fancy readout scale that you can print and attach to the device.
The video below demonstrates usage and accuracy of the prototype.

Marble Maze Cube (simple) - Plans

Time for another plans post! Here is a construction manual with plans for a very simple version of my marble maze cube. The idea is a three-dimensional, hidden maze through which one has to guide a marble or steel ball.
This cube contains one of the most simple mazes possible, where each "floor" can be solved alone to get to the next one. More complicated versions contain more changes between the floors.
Be sure to watch the time-lapse video of the simple construction process below before reading the manual! A 3D stereoscopic version of the video is available here.

ASCII Art Cartoons, celebrating 500 YouTube Subscribers

Celebrating one year and 500 subscribers on YouTube, here are some ASCII animations. Thanks to all of you for watching my videos!
ASCII art is the art of creating graphics using only text characters. It is not just an out-dated technique from the times of text-based computer monitors and communication, but a great way to produce animations with little effort. Be it a simple GIF animation as shown on the left, or a more complex cartoon as in the video below.
