Can my Canon Powershot A510 be Hacked?

My camera's video recording option is limited to 30 seconds which I think was done to prevent people from using it as a video camera and therefore drive sales for other products. I think that sucks. I should be able to record to my heart's content Does anyone savvy know of any way to hack the software/firmware to remove the 30 second limit?

Anyone know a good HDTV installer in LA?

I set up my big screen and I think I did a good job. Only there's a lot of artifacting on the regular TV channels (not the HDTV). That may be as good as it's going to get with my DirectTV box but I'm not sure. Can you recommend a good guy at a reasonable price in LA to come take a look at it?

Infrared remote extender thingy, who are you!?!?!

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!

Can I insure my Digital camera against losing it?

having just lost an expensive digital camara, and having had to replace it, is their some type of insurance that covers losing such items? I know renters insurance covers you if you get broken into, but I'm more concerned with losing items in public.

Charging electronic devices overseas

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.

Minimizing the electricity drain of plugged-in items?

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?
