evancohen/smart-mirror: The fairest of them all Touch Screen coffee table DIY with 32" TV and low cost CCD sensor I have already talked about the great hardware specifications of the Teensy board. But combined with the Arduino software environment, the Teensy also offers some great possibilities. But first let's install the plug-in Now you should see a category "Teensy" when you choose your board. For now, all of my Arduino UNO codes have been successfully built on the Teensy which means the adaptation between the ARM Cortex M4 and the AVR Atmega328 have been very well made. A for loop from 0 to the number of LED - Turn an LED on (as the LEDs are wired with the Anode on VCC and Cathode on the PIN, you have to give a LOW state to turn it ON) - ClearCCD(), The sensor has to be cleared once before reading the value... - readCCD(), read the sensor, if a value is above the calibration it is stored and the function return 1. - Turn the LED off (HIGH state for OFF in this configuration) If something has been detected, then the flag_detect is set to 1 and you enter the IF function.
Introduction · Smart Mirror Documentation ESP8266 Successor – ESP32 released with CAN support | An Engineer's Blog ​o, the interesting little ESP8266 WiFi SoC finally has a younger brother which appears to be even more capable. Among other interesting updates, the 32 bit Dual Core microcontroller still supports WiFi, but also Bluetooth Low Energy, a DAC, many more ADCs, GPIO pins, etc. etc. Lots of good details here: The ESP32 is now avaialble to buy directly as a chip, or on small development boards. The feature which particularly piqued my interest, however was the mention of CAN 2.0 support. There are already a number of other microcontroller which do offer CAN bus support (actually the list is probably huge since nearly all automotive and industrial spec controllers will) but for example the Arduio Due (Atmel SAM3X8E ARM Cortex- M3 CPU) and the Teensy development boards support CAN. So far i haven’t managed to find any now details on the cab bus interface.
Il Fabrique un Miroir Connecté avec Contrôle Vocal sous Raspberry Pi (Video) Inspiré par le travail de Michael Teeuw et Hannah Mitt, Evan Cohen vient de réaliser Smart Mirror, un miroir connecté sous Raspberry Pi. Ce modèle intelligent est entièrement contrôlé par commande vocale. Il peut donner la météo, des informations, la localisation, mais surtout allumer ou éteindre la lumière de la chambre avec ajustement de la couleur. Regardez la démonstration vidéo, c’est plutôt convaincant. Si vous souhaitez en savoir plus sur la conception du Smart Mirror , direction le site GitHub. source Requetes sur le meme sujet: miroir connecté raspberry piraspberry pi miroir tuto
Playing Chess on a Beautiful, Magnetized Globe “I think I can do it better.” Having this thought is a moment that every maker knows and loves. It is exactly what came to mind when Ben Meyers saw a picture of a spherical chess set online. The version he had come across used jacket snaps to connect the pieces to the board. He immediately thought this looked inconvenient and challenging to play with. Photography and media by Ben Meyers The board took about five weeks to complete from start to finish. It is obvious when looking at the beautiful final product that each piece was artfully crafted with exceptional attention to detail. From here, the base was turned on the lathe and a router was used to make the curved arm. Finally, the spacer and knob used to turn the board were made on the lathe. Meyers has had some difficulty getting people to play with him as the spherical chessboard can be a little bit intimidating. Meyers says he was surprised by how some aspects of gameplay changed on the spherical board.
Touch Screen coffee table DIY with 32" TV and low cost CCD sensor - 3 As Wikipedia is way better than me on explaining : "A charge-coupled device (CCD) is a device for the movement of electrical charge, usually from within the device to an area where the charge can be manipulated, for example conversion into a digital value. This is achieved by "shifting" the signals between stages within the device one at a time. CCDs move charge between capacitive bins in the device, with the shift allowing for the transfer of charge between bins. The CCD is a major piece of technology in digital imaging. In a CCD image sensor, pixels are represented by p-doped MOS capacitors. Basically, the CCD you find in a scanner doesn't read lights in two dimensions, but on one line. As I couldn't find any tutorials explaining how they work on the internet, I tried to understand the logic by myself. Then you can check if some lines are bigger than others (it's probably going to be the power and the ground, you can verify which one it is with your oscilloscope when the power is ON).
MEMS mike draws almost no power 25 May 2017 Acoustic sensor developer Vesper has launched the VM1010, said to be the first MEMS microphone to enable voice activation while drawing almost no power. The first member of Vesper’s ZeroPower Listening MEMS microphone product line, the VM1010 is said to allow product designers to offer touchless user interfaces without power consumption penalties. Consuming 6µA while in listening mode, VM1010 is said to extend battery life to months or years by enabling the rest of the system to power down completely while waiting for a keyword. “We are seeing a ‘Cambrian Explosion’ of voice-enabled consumer electronics, including smart speakers, smart earbuds and diverse IoT products,” said Matt Crowley, Vesper’s CEO. “By using materials that directly convert sound energy into electrical energy, VM1010 is the only MEMS microphone that uses sound energy itself to wake devices from sleep, while consuming negligible power.” Author Graham Pitcher
6 Best Raspberry Pi Smart Mirror Projects We've Seen So Far The magic mirror of the future won’t just say you’re the prettiest of them all. It’ll also tell you the time, date, weather outside, upcoming calendar appointments, and more. In fact, you can make such a smart mirror right now. A smart mirror is featured on one of these amazing videos to peek into the future. Why You Need a Raspberry Pi A smart mirror is basically a mirror with a screen behind it. The Pi is basically a credit card-sized computer. At the moment, no one has made a smart mirror with the $5 Raspberry Pi Zero. What You’ll Need Whichever smart mirror project you decide to do from this list, there are a few elements you’ll always need. A Two-Way Mirror It’s a smart mirror, so it should be no surprise that you actually need a mirror, right? An LCD Monitor This is the best way to make use of any old computer monitor you have lying around. A Raspberry Pi So far, no one has made a smart mirror with the $5 Pi Zero.

Literary gold mine for CNC millers From 1976 to 1983, Popular Science magazine, along with the American Plywood Association, ran an annual plywood panel project design contest for its readership. Often the winning projects were items of furniture, but that was not a requirement. A potter’s kick wheel and a folding plywood boat are notable exceptions. The rules were simple: Apart from common fasteners, the entire project had to be constructed from one or more panels of plywood, cut to make most efficient use of the material. In 1984, these projects were collected, by original contest editor Alfred W. Lees, into a book called 67 Prizewinning Plywood Projects. 1984, of course, was decades prior to the advent of accessible home CNC milling, so all those carefully shaped and slotted parts, at the time, had to be laboriously hand-cut using a jigsaw or similar tool.
Xonay Labs | Michael Teeuw When I built my MagicMirror 2 year ago, I could have never predict the popularity of the project. With over 2,5 million pageviews on my blog, 1250 stars and almost 500 forks of the GitHub repository and a growing list of MagicMirror builders, the MagicMirror project deserves some extra love. Time to announce something awesome! When I worked on the original project, the interface of the MagicMirror was just one of few stept in the process of making the first prototype. Because I never expected others to built upon my proof of concept, the software wasn’t as powerful and thought-through as it should have been from the start. In the past two years, many community members worked on expanding the MagicMirror system allowing them to customize it to their needs. There clearly was the need for a modular system allowing users to install extensions without the need to modify the core framework. So without further ado I proudly announce MagicMirror², The open source modular smart mirror platform!
