Arduino CNC Shield – 100% GRBL Compatable Do it yourself CNC projects are popping up everywhere and we decided that we wanted to contribute to the growth. Here are a few of our design goals: Modular Design – We wanted to do more than just keep cost down.
The Superior Works - Patrick's Blood & Gore: Planes #1 - #8 Quick Find: #1, #2, #2C, #3, #3C, #4, #A4, #S4, #4C, #4 1/2, #4 1/2C, #4 1/2H, #5, #A5, #S5, #5C, #5 1/4, #5 1/4C, #5 1/2, #5 1/2C, #5 1/2H, #6, #A6, #6C, #7, #7C, #8, #8C Let the games begin, starting with the bread and butter of Stanley, upon which they built an empire, the Bailey patent bench plane in its various configurations. Leonard Bailey designed what has become the standard plane configuration that's still in use to this day. Circuit Simulator Applet This is an electronic circuit simulator. When the applet starts up you will see an animated schematic of a simple LRC circuit. The green color indicates positive voltage.
Learn and Be Inspired by Deek Diedrickson's Book on Tiny Houses Steve Sauer relaxing in his Seattle, WA Pico Dwelling. Photograph by Andrew Pogue Photography Microshelters by Derek “Deek” Diedricksen. New Scientist Invention Blog The threat of terrorism has made reliable detection of explosives an important goal. While there are many methods for doing the job quickly and reliably, few of them are truly portable. This is because, before an explosive can be detected, many techniques require significant preparation of a sample, such as dissolving explosive residue in a solution, or collecting large volumes of air containing explosive vapour. Now, Rolf Hummel and colleagues at the University of Florida in Gainesville, US, have developed a portable technique that requires little or no sample preparation, based on the way explosives absorb and reflect light.
Opensource CNC controller written for Arduino’s (G-code interpreter GRBL) Traditional CNC machines used old-fashioned printer / parallel ports to connect to a computer. The computer then sends the signals to the motor’s over individual cables. So why would you want to use a Arduino powered CNC controller? Well the team from Dank that developed the software called Grbl have a few good reason for doing so. Here are their reasons.. Tilting router lift This is my tilting router lift. Being able to tilt a router lift really extends the possibilities for creating interesting molding even when using basic and inexpensive sets of router bits. I'm not the first to come up with a tilting router lift, there are even some patents for some designs (fortunately, the patented designs aren't very good, so no risk of infringing).
555 timer IC Internal block diagram The 555 timer IC is an integrated circuit (chip) used in a variety of timer, pulse generation, and oscillator applications. The 555 can be used to provide time delays, as an oscillator, and as a flip-flop element. La technologie NFC - Définition et utilisation What is NFC: definition? NFC, or Near Field Communication, is a short range wireless RFID communication technology. It means that two devices equipped with NFC technology are able to communicate with each other and share information as soon as they are close to one another. There is no need to launch an application, bringing the devices near each other automatically triggers the defined action - from a single easy "tap"! The NFC technology is derived from RFID (Radio Frequency IDentification) and works by creating a "near field" (maximum approximately 10 centimeters) using high frequencies that will allow to interact with NFC equipped devices.
