I was with a person that had an older style cell phone, I think it was an LG, but not sure. He was showing me pictures, but I was distracted with a series of around 10-12 numbers that were displayed on the screen, to the left and top of the picture area (not inside). They kept changing about once a second, each digit with no regularity. One would think that it may have been GPS coordinates but the numbers were too random and not changing in any particular sequence. What the heck was that? A tracking device? When I asked him what it was he very quickly deflected the question.

Just returned from fabulous 2 week holiday in New York. I Brought back Epson Artisan 800 All-in-One Printer from Staples costing $230. Unfortunately, I cannot use it in U.K., unless I plug voltage converter/transformer products. Has anyone else bought this set over there with more success? Any advice \ information appreciated. Please specify me What exact voltage converter product to buy & where to buy it from USA online store. Thanks. [more inside]

When I used to go visit my aunt who lived in a large house, she had a little console that sat on her kitchen counter with a speaker and a big button. When you'd press the button, it would buzz a similar console in the garage where my uncle worked, and then my aunt could talk to him. He could then hit his button and talk back. I guess it's like those things you see in movies where the executive "buzzes" his secretary. Anyways, what are those things called, because I need one. [more inside]

Electronics filter: Need to build something that'll light up different LEDs via radio frequency. Must be compact and battery powered. My electronics-fu is pretty good, but I'm not sure it's this good... [mi] [more inside]
