Inventor Open Sources "TV-B-Gone," and Why 340

ptorrone writes "Inventor Mitch Altman explains why he open-sourced his TV-B-Gone kit, the original stealth keychain fob for defeating TVs in public places. The title of the article is 'Patent-B-Gone' and perhaps the most interesting fact is that Mitch's brother is a patent attorney, but he still decided to release an open source hardware version of the TV-B-Gone, with pretty impressive results."

        I don't mind if a bar owner wants to put on a TV in his bar. That doesn't bother me. However, where I live (Orange County, Florida), there are television sets (with sound) in the following places that need not have them, and they are there for no other purpose than to show an announcement that could be served with a poster and no sound:

        • Libraries
        • Courthouses
        • Public Works Office
        • School Lobbies
        • University Common Areas
        • Hospitals

They are called "programs" for a reason. They program the viewer to pay attention. Most of the programming takes place on a subconscious level and has to do with alternating the volume levels (a simple example of that is that the commercials are always louder than the shows) and also with the frequency that the images are displayed and changed.

Go on and criticize, but as long as people will spend their money on it, there is someone out there making money by selling them what they want. When it gets too expensive, this over-consumption will stop. In the meantime, there must be people who like to go to bars with lots of TVs. Personally, I prefer to eat somewhere with a TV when I am by myself instead of hearing people criticize what I consider normal.

          There are also bars that have NO televisions in them.

          It's called freedom of choice and expression. Two of the things the American settlers left the old world for.

          We like having freedom of choice here. And our freedom of expression.

          The cool thing was, you could have gone to another bar, one you liked, instead of being in the "sports bar" style place.

          That's one of the things that makes our country a great place to live. We can actually make choices, and people with the drive to prosper can keep making (and I agree with you, I HATE the sports bar mentality, the TVs, etc) places the people want to go to.

It is much like a drug. Turning the tv off is more about breaking it's inevitable grasp on everyone's attention for at least a short time, so people look up and look around once in a while. It's not like you break the tv, it can be turned back on, and probably will be in short order.

That's why I don't get out much, I'm fed up going to bars where music is too loud to talk, people are staring at multiple TV sets spread around the place showing junk-TV shows and I get home with my clothes stinking like smoke so bad that I feel like puking.

        Nothing against football games. It's fun to get together with friends and watch the game at the local café. But having multiple TVs on all the time is annoying. And they're everywhere.

        • Within the last 10 years where I've lived, they have slowly outlawed tobacco in enclosed public places. Therefore, if you go out to the bar, the only place people can smoke is outside, on the patio. Ever since they did this, I've started to notice just how much of a problem the smoke was. It's really nice to be able to go into a restaurant, and not have to worry about smokers ruining the experience.

      I just recently left a commercial installer and all the professional TV's we were installing had no IR/RF it was all RS232 control. If they did the IR was on the back, and we would cover up the sensor with a backup IR control eye with a patch so nothing else could controll it.

      Most places I've gone to have done it right and installed TV's that you can't mess with.

      There are a few bars that have normal TV's. But if you're in a bar why would you be shutting of someone else's TV's in the first place?? what gives you the right?

A discrete little box that you stick on the IR sensor and block malicious signals. The box contains a couple of IR LEDs, and a descrambler chip. The chip decodes signals from the special remote control (which he also will sell) so that the stores still have control over their TVs.

Using that method, the store clerks would have to break out a step ladder and climb up to each TV, and pull off the tape any time they wanted to adjust the volume or change the channel, or turn the TV off at night.

      Because you're in the wrong bar. Bars do exist that provide a good atmosphere for conversation. I always make it a point to seek those bars out. In the US, most places that claim to be an English pub have reasonable volume levels but that's far from universal. I also look for bars that focus on drinks like wine or cocktails. I'm a beer drinker myself but the atmosphere is usually better in those places and they do usually have some sort of decent beer handy.

    I'm curious how avoiding patents, and open sourcing his product would protect this guy from a big company, that say... has a good partnership with Best Buy, making a copy of this product and due to it's bigger marketing power and retailer deal, taking all the potential profits away from the guy? Would his open source license protect against this? I'm not being rhetorical- I really don't know.

Keep up the good work! But please don't ask me to help.
