Sous-vide cooking involves cooking food in sealed plastic bags inside a temperature controlled water bath.
It's a technique that's been around for a few decades, but is just beginning to be popular in the home kitchen. We decided to give it a try by using a NerdKits microcontroller kit plus some items from our local Wal-mart and Home Depot to construct a sous vide cooker. The result is tasty food with textures and consistencies that are simply unachieveable by conventional cooking techniques! Normal cooking techniques, like heating in a pan or oven, rely on heating the outside surface of food via convection or conduction. That heat must then travel to the center of the food via conduction. In contrast, sous vide cooks the food for a long time at the final desired temperature.

NYC Resistor. Converting Cordless To Lithium Li-Po. Stefanv.com. "Spaghetti" IP Cam / Arduino Motion Detect Sprinkler. Posted by Phil Tucker on June 17, 2012 After a neighbourhood dog decided my front lawn was a fantastic place to poop on and his owners decided that they don’t care for bylaws I set upon finding a solution.
Sure you could try cayenne pepper, mothballs, ammonia or even marking your own territory (take that!) But I already had an IP camera monitoring my front yard for security purposes, so I figured I’d just hook up an Arduino and a sprinkler valve. This yard defense solution has two added benefits, it keeps my lawn healthy (I can set up timed watering through this system) and it sends offending dogs home stinkin’ wet. From me having to shovel dookie off my lawn to negligent owners having to deal with wet dog — perfect.
When the IP camera detects motion in configured regions of its video stream (the rectangles in the screenshot) it triggers one of its General Purpose Input/Output ports (GPIO). How to Build an Inexpensive Seismometer - make seismograph kit. New <em>Daybreak</em> AT&T commissioned short film features Nikola Tesla. Daybreak film segment featuring a model of Tesla'sWardenclyffe Tower Joe Kinney, Senior Project Engineer of the New Yorker Hotel, contacted me recently to inform me of a new short film featuring Nikola Tesla.
The film was produced by Ridley Scott Associates and was commissioned by AT&T to promote their mobile technology. The plot of the story revolves around the main character's attempt to unravel the mysterious death of his father who was on the verge of discovering the secrets of Tesla's wireless power transmission. The film is action-packed and very interesting. LCD monitor repair. I have noticed that many people find my blog when looking for monitor repair ideas. So here is another one of my ideas for monitor repair. I have in the past fixed laptops by retrofitting them with LED's. The problem with this monitor is that the power supply for the vacuum tube back lighting dies. The first step is to totally disassemble the monitor into little pieces, then carefully remove the gold colored trays that hold the vacuum tubes. Then carefully remove the tubes themselves without breaking them, like that can be done.
The LED's are spaced at about 1/2 inches apart by using the edge of a cardboard box as can be seen below. Electric Clothing. Solar Panel Setup around $100. 12V BoostPack. Replaces auto battery.
