When bikers want one-of-a-kind cycles with hand-built frames, elements like wiring harnesses must also be customized. Wiring is already a weak point for many bikes, so when Finch Customs is building its unique frames, like the Double Cross featured in the Discovery Channel’s “Biker Build-Off,” making sure wiring is not an issue is a key design parameter. Ron Finch and his co-designer, called Screwy, check wires hidden inside the frame using Fluke Corp.’s 88V, which features a beeper to signal continuity. The DMM helps the team understand the impact of using LEDs and incandescent bulbs, which have dramatically different current and resistance levels.
Researchers have been working on a number of alternative chemistries to lithium-ion for next-gen batteries, silicon-air among them. However, while the technology has been viewed as promising and cost-effective, to date researchers haven’t managed to develop a battery of this chemistry with a viable running time -- until now.
Norway-based additive manufacturing company Norsk Titanium is building what it says is the first industrial-scale 3D printing plant in the world for making aerospace-grade metal components. The New York state plant will produce 400 metric tons each year of aerospace-grade, structural titanium parts.
