Use for old digital cameras

Many people have old, low resolution digital cameras lying around from the previous generation. Here's a good use to put them to, particularly if you have a housekeeper.

When somebody needs to put something away, and they don't know where you like it to go and have to figure out where, have them pull out the old digital camera and take a picture of the item and a picture of where it was put.

Then every so often you can pull out the images into an online folder, ideally with a thumbnail browser.

Tales of the HDTV Superbowl Commercials Party

For the third year in a row, I held a "superbowl commercials" party. In this case, we used MythTV to record the game in HDTV for a while, then sat down to fast forward through the football and slow down to watch the commercials.

To bell the cat

Here's a simple though not too exciting idea. Make bells for cat collars in different pitches. Thus you can always know which cat is coming just by sound.

Closed caption history on demand

One thing I've noticed when you get a TV broadcast that has 5-channel sound, it that you get the voices on the center channel. Particularly with things like voice-overs, sportscasters etc. If you can mute the center channel, you can watch a game, for example, with no commentators.

But sometimes you do want to hear what they said, if there is something on the field you don't understand. If you have a PVR, you can rewind and turn on the center channel audio (though rarely is there a good UI to do this) but here's another idea.

Database Dangers: The easy evidence is what they follow

You may have run into the story of a fireman charged with burning down his own home. They charged him because his Safeway Club card records showed he had purchased the type of firestarter that was used in the arson on his house.

Sounds like a good case? Problem is somebody else confessed to the arson. He's now a free man.

Changing the nature of TV again

I love hard disk video recorders because they surprised me by being much more than super-fancy VCRs. They changed the nature of the way people watched TV in ways I didn't expect.

Now I've been working with MythTV which is an open source PVR. I have a new program in development, and if any of the readers out there are using MythTV I wouldn't mind some folks to test it out before I announce it to the Myth community.

This program does many things, including two things that I think could change the nature of how TV is chosen.

Two cables into the PC

In spite of all sorts of efforts, I remain amazed at how many cables still go in and out of my PC. My home theatre PC, which I recently wanted to take somewhere, had me unplugging power, ether, audio, digital audio/SPDIF, keyboard, mouse, cable in, video out and a serial cable providing PPP to the old Tivo. It could easily have had another video, USB devices like a printer and more.

Revealing you get stuff for free

Dan Gilmor notes that he is concerned about a new program called the "Silicon Valley 100" in which a marketing company identified 100 influentical silicon valley folks with plans to give us stuff in the hope of generating buzz. Dan worries whether people will disclose they got the stuff for free as part of this venture.

Paired lights for lit signs

You see it everywhere -- signs on buildings where a light has gone out. It is often amusing where a missing letter changes the name of the company in some silly way.

They spend fortunes on these signs, but bulbs are hard to replace. So why don't they make them with a special unit that has sockets for 2 bulbs, and switches over to the backup when the first one burns out? It's not actually that much more expensive, as you are going to pay for the 2nd bulb eventually (especially incandescent) though here you pay for it earlier.

Ultimate photographer's monopod

When you go out hiking and photographing, carrying a tripod can be too much, even my lovely carbon-fiber one. Besides, you want a good hiking stick on a hike anyway, you exercise more of your body. And most hiking sticks have a small tripod screw in them to use as a camera mount.

But here's a plan to make an all-out monopod/hiking stick kit to do a lot more than you can do with just the basic stick.

Ant-proof pet bowl

When you get an ant infestation here in California, you need to make sure your kitchen is clean with nothing to attact them. But if you have pet food out, they will find it.

In theory, ants won't crawl over some materials like vaseline. But if you coat the bowl rim with vaseline, it will get in the pet's hair.

Better door to door shuttles

Just back from the nightmare of holiday travel, which started at 5:30am on Christmas morning and a security line snaking all the way to baggage claim. Coming back 6 days later, I braved the door to door shuttles from the airport.

Make cheap ATSC (or DVB) RF-modulators

As I continue to play with HDTV, I found I had a horrendous time getting good output from my computer running the MythTV open source PVR into my TV. DVI, the uncompressed digital standard, just wouldn't work from the video card I had to the TV. The TV has Firewire/1394, which would allow me to stream mpeg-2 to it, and that would be really great, but as yet no software supports it because few TVs have such inputs.

More on entertainment.com

In my quest over the leak/sale of the entertainment.com mailing list, I have some amusing updates.

After telling them you don't respond to a "You sold my name" complaint with a request for all of the person's personal information, I got back yet another stock message, "Here's how you can get off our mailing list." I'm getting a lot of companies who use customer service reps for E-mail who clearly never read the E-mails. Yes, I also get software that auto-responds, but amazingly we also get humans who auto-respond.

Let's teach creation science in the schools

Creationists regularly complain that schools teach evolution improperly and should also offer creation science as an alternative. They went so far as to push one school board to put stickers on biology textbooks remindng students that evolution is a theory and should be critically viewed.

Some folks don't get it.

When I give an E-mail address to a web site, I give a different one to each site. I have many domains, including one where all addresses are forwarded to me unless I turn them off.

HDTV wishlist for MythTV

I have been building an HDTV PVR with MythTV and the pcHDTV tuner
card. It's been a major adventure, not yet ready for prime time, but
it's lead me to have some thoughts about things you want to think about
in a PVR that particularly relate to HDTV.

Let's re-see history in HDTV

For people of my generation, a great deal of history was seen on regular low-resolution TV. But a lot of it, up to the 70s or so (and often after) was shot on film, at higher resolution. Older generations saw some of this (once or twice) in newsreels at the movies.

So as HD sets become common, it would be great to see this old film footage of events like the wars, the Olympics, famous speeches, the moon landing and other space program material in high definition. I saw a DVD of the 1936 Olympics on a good screen and even that was surprising.

One fiber does it all

A short note, as I've been busy with a number of things including trying out PC based HDTV recording and mythtv, which I will write about shortly.

In a VoIP pricing debate, I calculated an interesting observation. Today we have voice codecs that can do very fine voice quality in about 25 kilobits. FM radio quality. Cell phone quality can be done in 7 kilobits. Anyway, that means all 200 million adult Americans could be on the phone at once and it would use 5 terabits.

Temporary split brain

This is a science-fictional idea, but strikingly probable. You are probably aware the brain is split into two halves, joined by a nerve bundle called the corpus callosum. People with severe epilepsy have had the callosum severed, and ended up having two brains in one body. A left brain controlling the right half, and a right brain controlling the left half. The left brain can speak and can lie, the right brain can write with the left hand to communicate.
