Help me name this device.... Saw this at someones house. A small device that allows you to control a dvd player or stereo (any infrared device) while it's within a cabinet with the doors closed. A small box is stuck on the outside of it that apparently catches the signal and transfers it inside and resends it to control the components within. Does that make any sense?? Where can i find this thing? Thanks!
Connecting my DVD player to my TV apparently damaged the latter's composite cable ports. Now I'm wondering if this could happen to other devices. [more inside]

If there is something available, what does it cost, is it worth it ?? etc. I live in Austin, Texas.

I'm traveling outside of the U.S. (to Israel) and want to know about charging my electronics. I'm only taking a few (I agree with comments in a summer 2005 posting that taking too much stuff can distract from the actual visit) namely my HP handheld (for contact numbers) and my digital camera. I may need to recharge both. I have the original charging cords, appropriate adapters and I have access to a transformer. Do I use the transformer, and is it safe to charge these devices overseas?

My partner is looking at buying a digital notepad/tablet, but we don't know much about them. Specifically she is interested in the ACECAD DigiMemo 692 from TigerDirect.ca. Google suggests that it's a decent piece from a crappy company. Does anyone have any experience with this (or other) digital notepads or this (or other) Canadian suppliers?

Is TIVO dying? I was about to buy a Tivo Box (I have DVR from Time Warner and it sucks) when a friend of mine mentioned that he heard that Direct TV was dropping Tivo and hinted that the company (tivo) was hemorrhaging money.

I recently read that anything plugged in continues to suck up valuable electricity, even when turned off. What's the best way to minimize this wasteful situation without constantly resetting/rebooting clocks,microwaves,tivos,answering machines,etc or constantly unplugging/plugging lights,cordless phones,tvs,stereos,etc? Any special gadgets or outlet strips that will help? Other ideas?

My car stereo was recently stolen. Since all I used it for was to route my mp3 player through the RCA in's, and since I've been kicking myself to start doing some DIY electronics projects, I'd like to make my own amp rather then buy a new stereo.

My MP3 player came with a pair of earbuds, the kind that basically look like tiny headphones with foam covers and sit in the cleft of the ear right in front of the canal. The sound is terrific, but I find them uncomfortable for periods of time over 40 minutes or so, and usually end up switching to a more comfortable pair of overear phones that don't get quite as good sound. Do you have any tips for making these more comfortable? Are my ears just the wrong shape?
