PHP DocWriter Summary PHP DocWriter is a set of PHP classes that allows you to create documents in OpenOffice.org XML format (that is, StarOffice/OpenOffice.org documents). It is also capable of communicate with the OpenOffice.org application with the purpose of convert OpenOffice.org XML generated documents to any other format supported by the OpenOffice.org application in an automatic and transparent way. Functionality The class is still under development but it's fully fuctional right now.

Map, Filter and Reduce — Python Tips 0.1 documentation These are three functions which facilitate a functional approach to programming. We will discuss them one by one and understand their use cases. 4.1. Polargraph Drawing Machine: 26 Steps (with Pictures) Confirm you have set the right serial port, and that it's communicating with the arduino by looking for a Polargraph READY! at the top of the window. This line will be red if it's not connected. If you connect the machine after starting the controller, then you'll probably need to close and restart the controller too. If you're running from Processing, then you should also be seeing incoming: READY in the Processing console every couple of seconds, in the background. That's great!
Introduction — Kivy 2.0.0 documentation Start Developing Kivy Apps Right Away! Creating Kivy apps is fun and rewarding. This guide should be the perfect starting point to get you on the right track for app development. cx_Freeze About cx_Freeze cx_Freeze is a set of scripts and modules for freezing Python scripts into executables, in much the same way that py2exe and py2app do. Unlike these two tools, cx_Freeze is cross platform and should work on any platform that Python itself works on. It supports Python 2.7 or higher (including Python 3). Learn Python Visually PDF download free – Learn Python Visually– WebUser – 18 May 2016– Custom PC – July 2016– Micro Mart – 19 May 2016– Tkinter GUI Application Development HOTSHOT Learn Python Visually is a modern breakthrough that makes learning programming more intuitive, easier, and fun Using the most basic approach to learning that we all inherently know from childhood, “Learn Python VISUALLY” solves the comprehension problem that so many other books cannot seem to bridge Visual learners retain information very differently than their left brained counter-parts, and thus benefit from different approaches Full color illustrations help memory triggers as your brain never forgets an image, metaphor or schema Illustrations can make a world of difference over strictly words on a page!
Vertical Plotter Gondola v3 (aka Polargraph) by rincey12 My version of a gondola (penholder) for a simple vertical plotter. See also the bead chain gear in my objects. See both objects in action in this video: There is also a slightly more complicated v4 here: These models (and some electronic stuff) are all you need to build your own vertical plotter. Sandy Nobles (creator of Polargraph) great Instructables is a good point to start:
Using Recorder.js to capture WAV audio in HTML5 and upload it to your server or download locally This is the 1st post in our new recording audio in HTML5 series. Next, we’ll cover using WebAudioRecorder, vmsg, the opus-recorder and MediaRecording API. Matt Diamond‘s Recorder.js is a popular JavaScript library for recording audio in the browser as uncompressed pcm audio in .wav containers. It is the 1st JS library to deal with audio recording in the browser – the initial commit is from September 2012, almost 6 years ago. Before it the only way was to use Flash. When used in conjunction with getUserMedia() Recorder.js can record audio from a user’s microphone (or other input devices) directly in your web site.
Arduino Wireless Communication - NRF24L01 Tutorial - HowToMechatronics In this Arduino tutorial we will learn how to make a wireless communication between two Arduino boards using the NRF24L01 transceiver module. You can watch the following video or read the written tutorial below. Overview For explaining the wireless communication we will make two examples, the first one will be sending a simple “Hello World” message from one Arduino to another, and in the second example we will have a bi-directional communication between the Arduino boards, where using the Joystick at the first Arduino we will control the servo motor at the second Arduino, and vice versa, using the push button at the second Arduino we will control the LED at the first Arduino.
Javascript Tutorial: Record Audio and Encode it to mp3 Explanation of Event Handlers: console.log("I was clicked") — set up logs to make sure button clicks are triggering the event handler.record.disabled = true — after clicking on the recording button, disable it so you can’t keep clicking on it during recording. After you click on stopRecord , re-enable the record button with record.disabled = false .record.style.backgroundColor = 'blue' — after the record button is clicked, change the color of the record button to signal that you are currently recording.audioChunks = [] — create an array to hold your audio binary data.rec.start() — begin recording. let rec = new MediaRecorder(stream); MediaRecorder is a built in class in javascript that allows you to save streamed media data inside an object. Call rec.start()to start recording the audio stream and rec.stop() to stop recording the audio stream.
SHIELD-EKG-EMG Open Source Hardware Electrocardiography electromyography shield for DUINOMITE, PINGUINO, MAPLE, ARDUINO like development boards This is an EKG/EMG shield which allows Arduino like boards to capture Electrocardiography Electromiography signals. The shield opens new possibilities to experiment with bio feedback. You can monitor your heartbeat and log your pulse, recognize gestures by monitoring and analize the muscule activity as it is done in this project. SHIELD-EKG-EMG converts the analog differential signal (the ECG/EMG bio potentials generated by muscles), attached to its CH1_IN+/CH1_IN- inputs, into a single stream of data as output. The output signal is analog and have to be discretized further with aim to give the option of digital processing.
