Not sure who the original post was a victim of.... but my chain drive door opener with a BLUE casing, Branded "DoItBest" [local lumber yard chain store] had the exact same failure. I went into the lumber yard with the busted off sprocket in my hand. Their eyes rolled back in their heads and they pointed to a box on the floor. It was 90% of the parts of a brand new unit, just like mine. The box had been opened to "warranty" some part or piece of the chain rail of somebody else's Chamberlain door opener. Apparently Chamberlain contract-bulids for DoItBest. The lumber yard boys were going to claim the whole thing anyway so they said... "help yourself to the power unit and bring yours back... no charge" And so, I got a new power unit, rebalanced the door, and I'm back in business, BUT I plan to inspect that shaft from time to time.

In a bid to boost the viability of lithium-based electric car batteries, a team at Lawrence Berkeley National Laboratory has developed a chemistry that could possibly double an EV’s driving range while cutting its battery cost in half.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
