|World's smallest autonomous racing drone proves to be a design challenge|
Scientists at Delft University of Technology in the Netherlands have created the world's smallest autonomous racing drone. The main challenge in making the 10-cm drone was using only a single, small camera and a highly restricted amount of processing. The main innovation was the design of robust, yet extremely efficient algorithms for motion prediction and computer vision.

|First all-electric Porsches: Taycan Turbo and Turbo S|
Move over, Tesla. The big kids are coming out to play. The world premiere of the first all-electric Porsches happened on Sept. 4, and the Taycan Turbo and Turbo S are, well, electrifying. The Turbo S (which doesn't have a turbocharger at all!) will do 0 to 60 in under 3 sec. There are lots of high-end features, with a focus on fast charging and sustainability too.

|A perennial reader favorite: Copper foam|
Copper foam from Goodfellow combines the outstanding thermal conductivity of copper with the structural benefits of a metal foam. These features are of particular interest to design engineers working in the fields of medical products and devices, defense systems and manned flight, power generation, and the manufacture of semiconductor devices. This product has a true skeletal structure with no voids, inclusions, or entrapments. A perennial Designfax favorite.
|3D Printing: Breakaway support material for complex FDM parts|
SABIC's AMS31F is a breakaway support filament for use with ULTEM AM9085F filament. The material maintains rigidity during printing and provides exceptional pliability during post processing to enable easier removal of structural supports at room temperature, which can reduce the time required to produce finished parts. Both AMS31F and ULTEM AM9085F filaments are compatible with Stratasys Fortus Classic printers and other industrial printers.
|Problem-Solving Tips: Screw tightening control methods|
Although the main role of screws (bolts) is fastening objects using the axial force generated from tightening in actual work, there are many people who control the torque by tightening with a torque wrench, because it is difficult to directly monitor the axial force, and so guarantee the axial force that way. However, there are other methods of control for tightening screws (bolts), such as using "elastic region tightening" and "plastic region tightening."

|Onshape includes PennEngineering PEM hardware|
Onshape, a next-gen cloud CAD and data management platform that speeds up product development, has partnered with PennEngineering, a global leader in the fastening industry, to include PEM hardware as a built-in standard for its 3D CAD models. Onshape will initially include PEM brand self-clinching nuts and self-clinching standoffs, and plans to add additional PennEngineering products to its Standard Content library in the future. PEM fasteners are typically used when a component must be readily replaced and where loose nuts and hardware aren't accessible during the final assembly process. By embedding a threaded nut into a piece of metal mechanically, it saves time and reduces post-manufacturing assembly processes. This efficiency is especially important when producing large quantities of parts.
|Replace traditional fasteners: 50+ retaining ring applications|
The benefits of a Rotor Clip Retaining Ring are simple: The ring is made from less material than traditional fasteners, eliminating machined shoulders, threads, cover plates, and heat-formed studs -- so you save. Using a retaining ring to fasten your assembly instead of a traditional fastener not only reduces your costs, but also saves the environment. Fewer parts and less material means cost savings for you and less waste for the planet. This quality part offers lot traceability. Want to know what you can do with a Rotor Clip Retaining Ring?

|Custom gearmotor lifts up to 10,000-lb boat|
A boat lift manufacturer contacted the engineering team at Bodine Electric Co. to assist in the development of a new high load-capacity vertical boat lift. The application demanded that the gearmotor be suitable for long-term use in a harsh waterfront environment, deliver high starting and running torque, positive locking capability when not running, and be powered by the 24-VDC battery/solar cell systems included on the lifts. The gearmotor efficiency also had to be high to permit many lift cycles from the charged batteries.

|Fun! Harley-Davidson electric balance bikes for kids|
Pedal bikes with chains are so 2018 for kids 3 to 7 these days. Well, that's not really true, but at least they have some neat alternatives. Harley-Davidson recently bought StaCyc, Inc., a maker of super-cool electric-powered two-wheelers for little ones. Revamped and rebranded as kiddie Harleys, you can now get a no-pedal electric-powered balance bike for that rider-in-training in your life. The IRONe12 (3 to 5 year olds, 12-in. tires) and IRONe16 (5 to 7 year olds, 16-in. tires) include quick-charge Li-ion batteries, ultra-low adjustable seat heights, twist throttles, tapered footrests, and lightweight aluminum frames. Progressive drive modes help with speed and control. Ride time is 30 to 60 min.
