"When frame their work as apolitical or “purely” technical, they are not being naïve. Some may genuinely believe that can be fully neutral, but many rhetorically employ a strategic naivety, because they know it allows the to continue to exist, and their employers to continue to benefit from its decisions about internet standards.
This cultural imperative to downplay or sideline politics in" decisions creates a steep hurdle for society.

So, over the last week or two, I've been working on building a physical #Cessna #C172 #skyhawk #simulator

Only now did I think it might be a good idea to start a thread documenting the design and construction, so here we go!

Enter the icon of industrial : the !

I went through about a dozen iterations trying to get these to work. The one pictured below was the first to work properly!

Originally, I started with the standard gears like you think of in a watch, but I quickly discovered that there were precision issues with the sizes I wanted, and getting the gears aligned when they don't barely weigh anything was tricky.

So, I quickly discovered that thicker gears work a lot better in these situations, but they have issues with lateral slipping. So, I discovered this herringbone design that works way better than all the rest.

Finally, I had an almost working design, but there were issues with precision from my 3D printer. The design was just too small. So, I upsized it to the biggest the 3.25" dial diameter could fit and got the gears pictured below.

If you're interested in learning more about the herringbone design, check out this video I learned it from: https://www.youtube.com/watch?v=FqNkHA6-61c

I work in a multidisciplinary medical research lab and study this stuff in grad school. On the physics side, we basically hack MRIs and any other superconducting magnets we can get our hands on LoL 😆

Found out why science hasn't been in my corner all week...

Been building a radio receiver to use with an MRI. This is my first time using these wire wound SMD inductors. They're a little over 1mm in size. But the challenging part is a coating that doesn't seem compatible with solder we have in the lab.

Right before I left the lab today I built a new circuit with ceramic inductors. It worked. Woohoo.

Last night my co-authors and I turned in the final chapter's first draft for our book, Practical Detection Engineering: A hands-on guide to planning, developing, and validating threat detections. Still got a few rounds of technical reviews and copy edits but definitely a big milestone for us.

When performing competitor analysis we found that despite the numerous amazing blog posts from industry experts, there wasn't a complete book focused solely on detection engineering, so hopefully we can fill that gap for the field! The book is scheduled to release in early August and is available for pre-order on Amazon now:
https://www.amazon.com/Practical-Detection-Engineering-Confidently-detections/dp/1801076715

If you have a Packt subscription, it'll be in the eBook library too.

Thanks in advance for anyone who decides to invest in our work and check it out!
