Sous vide cooking, immersing vacuum-sealed foods in temperature-controlled hot water, is all the rage in culinary circles, touting incomparable results achieving optimal doneness. But the price tag on most commercially produced machines is a bit steep, with $300 being the bare minimum, on upward to the thousands. Seattle Food Geek Scott Heimendinger was intrigued, but […]
Today, the latest newsletter went out for the Make It Last Build Series, sponsored by Microchip and Energizer. The goal for this week was to finish getting the stepper motor controller for our Drawbot working. By the time you’re finished, you should have at least one stepper motor turning in both directions on command. Check […]
Our new Arduino projects contributor, Riley Porter, has posted another cool project to our Make: Arduino page. In the project, he shows you how to hook up a Wii MotionPlus motion capture device to your Arduino to easily get 3-axis gyroscopic data onto the Arduino platform. You can use this set-up to control up to […]
Sweet! Make: Projects author Werner made an epic how-to on his teardrop camper trailer built on the frame of a cheap Craigslist popup camping trailer.
I’ve built a lot of stuff with wood in my life, but I do not consider myself a “woodworker” by any stretch of the imagination. When I evaluate a project that uses wood, personally, what I look for is the maximum cool result for the least amount of technical skill and work. Here, then, are ten of my personal favorite bangiest-for-the-buck wooden projects from the vault. Enjoy!
On Monday night IBM’s super computer tied the humans on “Jeopardy” – a few stumbles, by the end of the week, a winner will be declared… The computers haven’t proven to be our trivia overlords just yet. Give them at least until Wednesday. An IBM supercomputer named Watson finished one round of the TV show […]
Being made of glass, however, a proper Kipp generator is an expensive piece of apparatus, with new models costing upwards of $250US as of this writing. However, as the useful gas-generating reactions are usually aqueous, rather than organic, an all-plastic Kipp generator is almost as useful as a glass version. PVC pipe is inexpensive, durable, ubiquitous, and easily and securely joined using cement made for that purpose. Demountable PVC fittings are available in a wide variety of shapes and sizes and can be used to provide the necessary “dismantlability” for loading solid reagent into the device. Presented here is my design for such a low cost Kipp-type generator, with instructions for its construction.
