There’s always a risk that implanted medical devices will become colonized with bacteria, causing infections and sometimes even needing to be removed. Such complications could soon be less likely, though, thanks to a new graphite nanoplatelet coating.C… Continue reading Antimicrobial implant coating uses graphite to slice up bacteria
As many a fancy-refrigerator-owner will know, fingerprints tend to be highly visible on stainless steel. A new transparent coating could help, however, as it goes about reducing the appearance of prints in three ways…

TL;DR — Don’t use silicone to pot electronics.
That’s the conclusion [GreatScott!] comes to after trying out several methods for waterproofing electronics. His efforts stem from a recent video in which he discovered that water and electricity sometimes actually do mix, as long as the water is distilled and the electronics in the drink are relatively simple. He found that the main problem was, unsurprisingly, electrolytic corrosion, so he set out to experiment with various waterproofing coatings. In a series of careful experiments he goes through the pros and cons of both conformal coatings and potting compounds. The conformal tests …read more
There’s no beating the beauty and durability of a high-quality powder-coated part. There’s just something about the look and feel of the finish that goes far beyond mere painting and makes it worth the effort and expense. The typical electrostatic spray powder-coating setup can be expensive, though, and not necessarily suitable for every workpiece.
Enter the fluidized-bed powder coating chamber, perfect for limited runs of small parts, and the brainchild of [Andrew Mayhall]. With a business providing furniture kits based on iron pipe, [Andrew] needed a way to finish flanges and fittings, and powder coating provided the best look. The …read more
