Comment Re:Walking on sand (Score 2) 210

You know, we're engineers some of us? Let's "run the numbers" ....

Assume walking is about the same metabolic equivalent as riding a stationary bike lazily (http://en.wikipedia.org/wiki/Metabolic_equivalent), you expend about 50W more or less. So a 10W shoe is going to make it about 20% more "difficult".

Hard to say how that will "feel". "Walking on sand" seems to about sum it up.

Or make the PS auto-sense the required voltage. I dumpster-dived a Targus laptop supply a few years back. Their absurdly overpriced tips simply include a resistor which feeds back a sense voltage to the PS though an additional lead in the cable, so with the addition of a trimmer resistor heat-shrinked into the power cable I now have a power supply that (with the aid of a voltmeter) will deliver between 9 and 20-something volts. This kind of feedback can be built into a PS for cheap.

Comment "Betters?" (Score 1) 581

What are you, a butler on some English grand estate? A doctor or bike shop owner isn't your "better", hopefully you regard them as some kind of fellow professional. If you enter into a business relationship with some kind of class warfare in mind, you're going to get treated like dirt.

Comment Tongue stylus (Score 1) 208

The teledildonic French kiss adapter, discussed yesterday, might be useful in addition. Do people with these disabilities have more precise control over their tongue or their heads? It's probably a matter of personal preference. There are also those who communicate by puffing into a device, either in morse or some other code.
