The fast food epidemic

I recently stumbled upon Robert Lustig's lecture entitled Sugar: The Bitter Truth. I recommend it highly -- at least the first half, after which it becomes a bit too technical -- for understanding exactly why fast food is killing us. As Lustig explains, there are two killer elements in fast food. One, fast foods contain lots of bad sugars like fructose and sucrose (most of all in the biggie sized sweetened sodas that accompany each value meal), which cause the body to do a poor job of knowing when it doesn't need any more food. (Contrast this with glucose, the good sugar that is present in maple syrup or honey.) Two, fast foods remove the fiber so that the food will cook faster. The reduction in fiber causes the body to absorb more sugar and do an even poorer job of knowing when it doesn't need any more food. So, fast foods offer a double whammy -- extra sugar combined with little or no fiber. Similarly, fruit juice is worse than fruit, because (you guessed it) it has the sugar but not the fiber.

Milwaukee Appliance Hand Truck

Image
Milwaukee Appliance Hand Truck, leaning against my shed Also known as a cart or a dolly. The model is HDA700. I paid around $120 for it. Here's a list of the features. Wrought iron frame 800 pound load capacity 6 inch non-marking wheels (solid, non-inflatable, never go flat) Stair climbers to help move loads up and down stairs and curbs Padding to prevent the cart from damaging the appliance (this is the white strip in the picture above) Belt or strap that goes around the appliance to secure it to the cart and keep it in place Manual ratchet belt tightener, the buckle-like part at one end of the belt (more on this below) Belt tightener handle (this is the red handle in the picture above) to add more tension to the belt once the manual ratchet has been used to the tighten the belt  I recently used this hand truck to move a big ass 320 pound refrigerator out of my garage (where it was delivered) and up a couple of steps to the deck, up one more step through the doubl...

My Experiments with the PICAXE 08M2+

Image
PICAXE 08M2+ I generally prefer to do things the hard way. For example, you can either microwave a frozen dinner or cook from scratch. The microwave option is a good backup plan, but cooking from scratch has far too many advantages, as I outlined in a recent blog post on the do-it-yourself way of life. In the electronics and robotics world, the analogy of cooking from scratch is to build circuits using a bare bones micro-controller chip (e.g. the PICAXE ) rather than a fancy board (e.g. the Arduino ). Therefore, once I get a circuit working with the packaged Arduino approach (e.g. this robot I built recently), I usually try to replicate the circuit using more basic components like the PICAXE. My decision to consider the PICAXE was influenced by Charles Platt's coverage of it in his awesome book Make: Electronics . But essentially, I am a minimalist and I want to see how much I can get done with a bare bones chip rather than a bulky board-based micro-controller like the Ar...

Utility trailer buying guide

Image
Introduction I recently bought a utility trailer . (I'll explain momentarily what that is and why you might consider buying one.) Going through the process (research, preparation, purchase, registration, setup and maintenance) has taught me that it's not a simple endeavor and very little good documentation exists in the public domain (e.g. on the Internet). Hence, this post. Research In dictionary terms, of course, "to trail" means "to follow" (or to trace the path of a primary vehicle). Alternately, Wikipedia defines a trailer as an unpowered vehicle pulled by a powered vehicle. So, let's get acquainted with what a utility trailer is and why you might consider buying one. If you're a hardworking, blue collar American you probably already have one -- it's the back half of your pickup truck . Well not quite, but that's the reason Australians refer to a pickup as a utility vehicle. A pickup is characterized by the presence of a flat...
