Less is more. Researchers determine a way to emulate insect eyesight to ditch accelerometers. In a search to understand how insects sense gravity, this might be an opportunity to model insect movement using optical flow, to find more utility in the onboard cameras.
Update on SLAM
I like SLAM. I find this article useful. Telemetry and control in a single gear. What’s not to love? The problem, again, with pretrained AI is that the drone cannot necessarily learn much new stuff. It just arrives “aware of” things like trees, vehicles, and people and such. Drones do not “find” power lines affixed to poles of a regular size and distribution rate along roadways, yet they exist. where else do you find them? it would be cool to be able to detect the lines using infrared sensors.
Train tracks provide an alternative to travel over roads, empty lots, and existing property. It is safe and brilliant. Drones can also be used to spot maintenance issues, wildlife, erosion, and other forces that shape resource management. Drones could be used to monitor remote RTUs for switching and rail management. They can provide volumentrics for grading, advanced planning, and emergency management, including lights and airborne medical supply transport.
Nematodes! NEMS are Nano Electro-Mechanical Systems. I am only posting this as a jumping-off point for engineers who might be interested in shrinking avionics needs on drones. Scientists found that DNA acts as a moving vehicle within an electric current that can rotate at 10^9 rpm. That’s ridiculous. Also, that’s a microscopic turbine, so it has torque, and measurable changes in gyroscopic forces can be used to measure changes in position. But what about optical gyroscopes, laser ring gyros? The Sagnac effect can be used to measure changes in position based on the change in interference patters of lasers pulsing at different phases. These same forces can make sound appear to be louder or softer, wavy. With slight variations in a certain range of audible (less than 1500 Hz with a difference less than 40Hz) sounds), you can discern binaural beats in the tones, an illusion produced by the brain’s inability to register phases of sound, only amplitude and direction. Less is more.
The possibility of phonons replacing photons in quantum positioning devices might be a cool launching point for discoveries. Hardware with smaller form factors might even be more accurate. If you want to have quantum LiDAR, then you need systems that can exploit metamaterialized superconductors and such.
I was presenting some content to tie MIR sensors to chalcogenide glass, and somehow the version never made the automated changelog for the website. I probably preempted the save by closing the laptop too soon after hitting ‘save’. I have had an issue with Outlook Mail providing the same problem.
The three days I participated as a volunteer instructor at Verticals were as follows: April 28th, May 5th and May 12th, 2022. I guided students through the process of learning how to safely fly drones in uncontrolled airspace. Two students flew my professional drone over the nearby Monongahela River, by an old truss bridge. One landed the professional drone, wow! On the first day! We planned a video with storyboards and a huddle on production elements. They brainstormed, scheduled shots, got gear, and produced the footage. One the last day, students edited and shared footage.
I basically hustled parts, minor repairs, battery charging, and network connections to and from supply to the production locations. I answered questions. One team was outside the building, another inside. I invited students to explore their own styles. They had fun. The teams erupted with creativity and effort. I had hoped to use the course module in a creative writing lesson or a programming lesson. The presentation that I use sort of serves as a class rubric, but I supply the students with worksheets to plan their productions step-by-step.
I learned some crucial limitations and opportunities for the next session. The most valuable thing is to have a report formatted to assign communication channels, teams, roles, and work schedules. Safety issues were routinely handled successfully. All craft and pilots, tablets and other parts of the Uncrewed Aircraft System (UAS) made it back in the box, so to speak. All inventory recovered, repairs and orders made, all data shared in the cloud, students back in their districts, rooms ready for the next class.
Verticals is a local community development center that gives kids a choice of after-school programs that enrich young lives and provide a sense of pride in community. A link to the group is provided. Some school districts, like Monessen and Brownsville, pony up transportation. It makes a huge difference to the kids, and I am grateful to meet the van drivers. They like the class, too!

I can see a drone academy being a part of an 21st-century community, so I am studying what we need to do to qualify to become a FRIA. I have a break from school in a month, and I like to read legislation. One of the problems is that it’s not 1986anymore. These rules were written before the Internet absolutely debased the concept of community. It used to involve, at the very least, physical mail for remote correspondence, on land lines, even. Brick and mortar have given way to ones and zeros. The architecture is in an electric field instead of a dirt lot. “Model aviation” was a concept that existed before FPV, before streaming, before smart phones, before laptops. Ridiculous changes continue to occur and need to occur more quickly because of climate change.
(1) is described in section 501(c)(3) of the Internal Revenue Code of 1986;
(2) is exempt from tax under section 501(a) of the Internal Revenue Code of 1986;
(3) the mission of which is demonstrably the furtherance of model aviation;
(4) provides a comprehensive set of safety guidelines for all aspects of model aviation addressing the assembly and operation of model aircraft and that emphasize safe aeromodelling operations within the national airspace system and the protection and safety of individuals and property on the ground, and may provide a comprehensive set of safety rules and programming for the operation of unmanned aircraft that have the advanced flight capabilities enabling active, sustained, and controlled navigation of the aircraft beyond visual line of sight of the operator;
(5) provides programming and support for any local charter organizations, affiliates, or clubs; and

Topics in the Verticals Youth Empowerment program include artificial intelligence (AI), robotics, drones, digital fabrication, coding, media production, design studio, blockchain, and crypto. Courses in the topics are presented alongside fitness and wellness resources. The center director is retired NFL pro-football player William James, who stepped off the gridiron and into a new life arena. William has an amazing base of supporters, collaborators, volunteers, and stakeholders who help make this happen. Very grateful.
Verticals Youth Empowerment Center is designed to stimulate young minds, give parents an inclusive environment in which to socialize, and to offer youth a sense of pride in themselves and their community. There are other facilities in the works.
