That said, it’s less crazy than one might assume at first […]
We typically think of neon signs as big commercial advertisements, hanging inside windows and lofted on tall signposts outside highway-adjacent businesses. [James Akers] has gone the other route with a fashionable build, creating little wearable neon necklaces that glow beautifully in just the same way.

To build something with these logic families nowadays requires an intense treasure hunt of antique components bordering on impossible and/or expensive. Rather than going down […]

[Icoso Labs] explains how it’s done, with plenty of handy tips along the way. There are three primary things you […]

(Credit: Excessive Overkill, YouTube) Industrial robots like robotic arms are basically everywhere, albeit usually out of the public’s eye in factories.
