Electronics: Germanium Diode- Testing and Analysis

I've never really had the chance to use or test out a germanium diode before, so this was an exciting opportunity for me to try one out! Of course, I first wanted to see if the sayings that there would be voltage drop of around 0.3 volts would be accurate...

Electronics: Germanium Diode- History and Uses

Currently, my basement has flooded, which means a pause for my projects for a little while. I'll be getting back to the Filastruder project soon. In the meantime, I have some interesting information about the history and information of a part that I found in some old boxes of components- a germanium diode.

Filastruder: Introduction

After I had my 3D printer for a couple months, I had the urge to extrude my own filament. Filament isn't that cheap, and by extruding my own filament, I would have the ability to use whatever plastics I wanted, and whatever amounts I wanted. All on my own time.

So, I bought a Filastruder kit!

Thingiverse Reviews: #414556 3D-Printed Screw-In Front Lenscaps

Welcome to this week's edition of Thingiverse Reviews! Today, we'll be looking at one of the latest prints I tried out- the 3D-Printed Screw-In Front Lenscaps by profhankd. Pictured here is one of the lenscaps that I printed, attached to the lens of my camera.

3D Printing: How Long is a Roll of PLA Filament?



I've been wondering for a while how long a roll of 3mm PLA is, and today I decided to find out. Not by unrolling the filament roll, of course, but by using a little math.

3D Printing: Precise Color Changes: Step-by-Step Part 3- Printing

Last week, I described the process of making a print with a precise color change. Using the CuteOcto.stl file, we created a gcode file with a color change 30 layers up in an 85 layer print.

3D Printing: Precise Color Changes: Step-by-Step Part 2- Combination

Now that we've exported both of our STLs into g-code, it's time to combine them into one part. We'll be using YAGV, or Yet Another Gcode Viewer, to view these files. It can be run in the downloaded directory (cd yagv-master) with python yagv [filename.gcode], with your own G-code file substituted with "filename.gcode".

3D Printing: Precise Color Changes: Step-by-Step Part 1- Planning

Last week, I described the overall process that I used to make quick color changes with my printer. This week, I'll show you exactly how these color changes are done.

The underlying principle is that the excess filament should be put somewhere that is out of the way of the rest of the print while the colors are changing. This consists of these actions:

1. Move the hotend above the print
2. Move it over to an area that is not occupied by the print
3. Begin printing a cube that is large enough to contain the filament already in the extruder and what needs to be switched
4. Switch the filament by hand
5. Let the cube finish printing
6. Move the hotend above the print
7. Return to the print
