Lost in Space has got to be one the most classic robot shows ever made. Here is an Old-School video that I believe was done quite well. The Song is called The Robots by Kraftwerk.

The robot waitress server, Now you never have to get up again because this robot is ready to serve you, the beer drinking master. I do admit the waitress may need some redesign to look a bit more feminine, but it’ll do for now.

Now for the critical very last drop at the bottom of the glass, it’ll even shake it for you! How could you ask for anything better. Well, now that you mention it, it could be really neat if the robot set it on a conveyor belt after and sent it away right to your seat. But then again that is what the robot waitress server is for

I especially like how this beer pouring robot pulls off the bottle cap! it uses a nail off the wall of the garage to conveniently pull the cap off. Then it conveniently disposes of the excess bottles.

The Asahi Beer Pouring Robot may be a slightly more affordable robot for your beer drinking needs. Although not nearly as fascinating as the big beer pouring robots, the Asahi Beer Pouring Robot is compact and even works as a refrigerator to cool your beer before pouring you an ice cold beverage. The Asahi Beer Pouring Robot is even a production model designed for consumer use! Or consuming use, but either way I think you will be left completely satisfied.

Ahh, it always makes you feel good inside watching other people getting hurt after doing stupid things. Especially after dressing up in beer can boxes and claiming to be a beer robot. Don’t you agree?

Enjoy

Now it’s time for you to make one of these robots with the Parallax Propeller microprocessor chip, if you decide to make one I will too, so we can battle! I’m serious about this. It would be awesome to make one of these with the Parallax Propeller chip. Probably wouldn’t be too expensive or difficult either. I looks like they used a RC radio controller to tell the little red robot where to go and what to do next. It look like the robots just have preset routines coded into the microprocessor and when certain button combinations are pressed, the robot will perform different moves. It looks simple, and it would almost be just like the fighting games for the PC or consoles but in real life instead! The Parallax Propeller chip is the way to go.

When watching How to Create a High-Def speaker for under a buck, you may think to yourself, “Hmm, I wonder if this works?” Haha, the answer is no. This is not the way to make a high definition speaker for under a buck. In fact, even if you did get a speaker to work for under a buck it wouldn’t be high definition. When marketers claim a speaker has “High-Def” they are mostly just trying to get you to buy their product. It’s an appeal to logic based on semi-false claims.

The way a speaker works is based off the basic principles of an electro magnet. You have to start with some form of a coil that will create an electromagnetic field to push or pull a speaker cone back and forth. All the cone does is push air and create vibrations by pushing and pulling at a certain frequency determined by the pulses generated by the music payer.

So in a nutshell, here is how something like a set of headphones works: The music player sends out pulses that flow into the electromagnetic coil, and the electrical pulses are turned into an electromagnetic field that pushes or pulls on either a big magnet or just something metal that is magnetic. The object pushed or pulled is connected to something big and flat but also lightweight that will push lost of air. The more air that can accurately be pushed at one time, the lower the frequency of bass can be produced.

However the lower the frequency and the larger the amount of air pushed the more power you need to make it work. Headphones usually don’t have much base because they can’t get enough power to produce sound. So if you want more bass and more volume you need an amplifier. The way you get what advertisers call “High-Def” is by creating a full range of sound over the whole sound spectrum, and also doing this by having a balanced volume over all the frequencies. The only way to do this is by having speakers of different sizes. Although there all “full-range speakers”, you still get better sound by having multiple sizes of speakers.

Why the speaker in the video doesn’t work:

1. In the video “How to Create a High-Def speaker for under a buck”, they used a paper plate to push air, but they didn’t have an electromagnetic coil to push the plate and air back and forth.

2. In the video “How to Create a High-Def speaker for under a buck”, they are hooking it straight into an iPod that won’t put out enough power (amps) for a speaker that size.

3. In the video “How to Create a High-Def speaker for under a buck”, they claimed you can get “High-Def” from the one speaker, but they are wrong, you need more than one.

4. In the video “How to Create a High-Def speaker for under a buck”, they used people’s ignorance to get them to make something and get confused and angry. They were all victims of a hoax. Congratulations.

But on the brighter side, they are ways to make a simple speaker out of a cup or a bowl that do work. And you can even make them for under a buck. Here is one design below, just make sure it has an electromagnetic coil for pushing and pulling air.

Have fun

Now it is the task of you and I to generate enough electricity off a cat to power your Parallax Propeller chip. It really won’t take much, and just think about all of the exciting things you could do! Such as creating blinkers for you cat when it turns left or right, or a beeper for when it backs up. Here is a preliminary design idea for you to think about. I think this just might work!
