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.

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

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???
