Why no links from the video to the actual project?

Why no links from the video to the actual project?--This looks like it has been inadvertantly left out of most/all of the recent Gadget Freaks.

I am not singling out this particular project. (I was interested enough to search the information out, and to log in and speak up)

I get an email with a link to Gadget Freak, but only to the video. I find no links anywhere on the video page or in the video that leads to the actual project information. (I am most interested in reading the schematic and what was done to accomplish the project)

I had to go to the DN home page and find the Gadget Freak ad on the right side, click on that and search the projects to locate the one I was interested in.

 

I hope this can be fixed for future projects. Maybe past ones too???

I've seen older solutions that amplified the noise generated by a Zener diode. Digital uber analog now a days. Good thinking!

The impressive part of this is the cost -- without the transistor, under a dollar. With the transistor, it's $1.50. That, of course, assumes you have some speakers handy. Nice idea, good execution.

Latest Analysis
From home enthusiasts to workers on the manufacturing floor, everyone's imagination is captured by the potential of 3D printing. Prototyping, spare parts creation, art delivery, human organ creation, and even mass product production are all being targeted as current and potential uses for the technology.
ABI Research, a firm based in the UK that specializes in analyzing global connectivity and other emerging technologies, estimates there will be 40.9 billion active wirelessly interconnected “things” by 2020. The driving force is the usual suspect: the Internet of Things.
Just in time for Earth Day, chemicals leader Bayer MaterialScience reported from the UTECH Europe 2015 polyurethane show on programs and applications using its materials to help reduce energy usage. The company also gave an update on its CO2-based PU as that eco-friendly material comes closer to production.
Solar and wind energy are becoming more viable as a source of energy on the electric grid. For decades, the major drawback to solar and wind was that they’re temperamental. A cloudy day kills solar and a still day renders the wind turbines useless. Automation tools, however, are providing a path to help these renewables become practical.
In honor of Earth Day, the National Security Agency has launched the STEM Recycling Challenge in Maryland schools to encourage kids to think about where the garbage they throw out every day actually goes. The agency has also introduced “Dunk,” a muscular blue cartoon recycling bin wearing shorts and sneakers.
