BIVBlog #25: Highlights from RIPE-68 and about my secret project

Here are my personal highlights from last week’s RIPE-68 in Warsaw/Poland, and some quick info on a secret little project of mine.

    RNGs: From the need for 12V, I can probably guess what your basic design is. A few years ago, when game ports were still popular on PCs, I did a 5V-only thermal noise source.

    That was what I ended up with once I had considered manufacturing and testability. If you go this route, mail me. There are some layout tricks.

      Hi Kasper,

      no, it’s not a thermal noise source, but a Zener/avalanche diode. The idea is that it is meant to be built from general-purpose, widely available components and is done in such a way that anybody with an oscilloscope and some basic knowledge how to use it can actually verify that it hasn’t been tampered with.

      The core circuit I am currently using (excluding the step-up converter, microcontroller and USB interface chip) gets away with a zener diode, two transistors, two capacitors and five resistors.

      Last night I’ve tried to record an overview episode over the hardware design I use so far, but it turned out *way* too long. If I find the time tonight, I’ll give it another try.
