I want universal DC power

I went around and counted that we seem to have around 30 birick and wall-wart DC power supplies plugged in around the house, and many more that are not plugged in which charge or power various devices. More and more of what we buy is getting to be more efficient and lower power, which is good.

But it's time for standardization in DC power and battery charging. In fact, I would like to move to a world where DC devices don't come with a power supply by default, because you are expected to be able to power them at one of the standard voltage/current settings.

Fix some eBay feedback problems

Like many, I am interested in reputation systems, and eBay has built the largest public reputation system. Many have noted how feedback on eBay is overwhelmingly positive -- a 97% positive rating would be a reason to be wary of a seller.

It's also noted that people do this because they are scared of revenge feedback -- I give you a negative, you do it back to me. One would think that since the buyer's only real duty is to send the money that the seller should provide positive feedback immediately upon receipt of that money, but they don't.

Design of the ideal digital AV system and the Broadcast Flag

For some time I have been musing over the design of an ideal home A/V system using digital technology. Sadly it's not coming, in part because it's illegal under the new Broadcast Flag rules.

To read my design of this system, and the musings of the legality of it and why that presents a problem, see a draft on an Ideal A/V digital system
