Low Power Ethernet Hubs?
mike.851 asks: "I'm an engineer working in the embedded systems field. For the past few years, I've been using RS-232 to interconnect various modules into the embedded systems that I build. Lately, I've found that RS-232 simply isn't flexible enough for my growing needs. I need to switch to something else, and I don't think that USB is really an option for me. I've been looking into embedded ethernet as an alternative. I've found several great low-power platforms for hardware development including several of the uClinux kits as well as products from Rabbitsemiconductor. However, I'm having trouble finding ethernet hubs that meet my power requirements (my goal is 2W or better for the hub). So far I've found Ctrlink and W-linx, and I've considered replacing the power supplies in commodity hubs with switching regulators. Does anyone have experience with these products? Does anyone know of other low-power hubs? Thanks."
At any rate, wireless power exists everywhere, even before Tesla. It's in T-storms with their lightning. It's in the water. It's in the wind. It's in the earth, the sun, and all atoms. And that's just the stuff we can get at right now! Wait until someone makes a Dyson sphere!
They who would give up an essential liberty for temporary security, deserve neither liberty or security
Tesla coils (haha, funny joke) were groundbreaking because they managed to place electricity in a usable form that didn't require a wire. Blowing wind across a room doesn't count either - you'd need a generator to convert it then. BTW Joe... exactly what is it that you accelerated into? It appears to have had an impact on your logic. (yeah, a pun, no kidding)
