A Maker’s Microwave

How many microwaves have you thrown out because they get flaky after a few months? The thrift stores are full of these rejects. How many times have you wondered who designed the user interface for these things? What planet were they from? Wouldn’t it be nice to have a microwave that isn’t flaky and has a sensible interface?

Nathan did exactly that. He took a broken microwave and put in his own smarts via a Raspberry PI. It has a beautiful control panel, accepts voice commands and provides voice synthesized feedback. It even scans a product bar code to fetch cooking instructions. It is so smart, that you don’t have to babysit the thing to stop it to stir. With the bar code powered instructions, it will stop at the right time, tell you to stir, and start up again to finish the cooking. He even did a tablet interface.

The key to a project like this is a microwave with an intact magnetron, which is the tube which does the cooking. As already mentioned, most of the time these tubes are fine. It is the sorry electronics that flake out. Take inspiration from this guy. You don’t have … Read the rest

Get Accredited Degree Online

While many universities have been offering some of their courses online for a few years now, none have offered actual degrees (aside from dubious “professional” colleges). Georgia Tech is first to have taken the leap. In collaboration with Udacity (which I have written about before), they are offering an accredited masters of computer science degree for $7,000.

Of particular interest is the fact that the actual courses are free. It is only the degree that costs money. This is nevertheless good news. There are a number of positive things to note:

  • An actual college degree can be obtained online from home without having to move and live near or on a campus.
  • The cost is much less than tuition for the same degree is normally; not to mention the considerable savings in living expenses.
  • The actual education is free for everyone in the world.
  • The degree is obtained via proctored exams offered at 4000 Pearson locations around the country.

That last item also points to another positive trend – certification by exam. Currently, the primary value of a college degree has nothing to do with education. Its main value is the piece of paper that opens doors into the world … Read the rest

Nanotechnology at Work – A Wonder Waterproof Coating Now Available

There is a new two-part coating that will make anything waterproof. Called Ultra-Ever Dry, it is nano-technology based and works wonders. Watch the video below and be amazed:

The only problem with this product is it is far too expensive to be practical and only comes in large industrial quantities.

There is now good news. Rust-oleum has brought out a similar product called NeverWet. You can buy it at Home Depot for only $20 for 18 oz. It is still pricey, but practical for many things. Imagine boots that cannot get wet or even muddy. This product is definitely not your father’s Scotch-guard. I just hope there isn’t a patent war, putting this technology out of reach for us regular folks.

If you use this product, please share the applications you find for it in the comments.

Why You Should Homeschool Your Child

Here at ProvideYourOwn, we believe one of the most important things you can do for yourself and your children is to teach them at home. If you need yet another reason to do so, take a moment to watch this telling interview with Michio Kaku on how children’s intellect and desire to learn are crushed by the schools:

Of course, homeschooling is not a panacea if it duplicates the public school model. Set your child free – let him or her direct their own learning. That is what children are designed to do, and it makes your job as a mom or dad that much easier.
