\n!SocketIO Arduino Client, an Arduino client for connecting and messaging with Socket.io servers\n\nBased on Kevin Rohling's arduino websocket client modified to work with socket.io servers. Along the way, all uses of the String class were replaced with fixed char buffers so as to use less memory.\n\nThe bitlashsocketio.ino example provides an integration with Bitlash on the Arduino and a node.js example server that can be used to send Bitlash commands over the Websocket fabric to the Arduino, and see its output in reply.\n\nKevin's documentation is reproduced hereinafter, with changes as needed.\n\n!Caveats\n\nThis library doesn't support every inch of the Websocket spec, most notably the use of a Sec-Websocket-Key. Also, because Arduino doesn't support SSL, this library also doesn't support the use of Websockets over https. If you're interested in learning more about the Websocket spec I recommend checking out the Wikipedia Page. Now that I've got that out of the way, I've been able to successfully use this to connect to several hosted Websocket services, including: echo.websocket.org and pusherapp.com.\n\n!Installation instructions\n\n\nClone this repo into your Arduino Sketchbook directory under libraries, then restart the Arduino IDE so that it notices the new library. Now, under File\sExamples you should see SocketIOClient.\n{{{cd ~/sketchbook/libraries && git clone https://github.com/billroy/socket.io-arduino-client.git}}}\n!How To Use This Library\n\n{{{\nbyte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED };\nchar server[] = "echo.websocket.org";\nWebSocketClient client;\n\nvoid setup() {\n Serial.begin(9600);\n Ethernet.begin(mac);\n client.connect(server);\n client.setDataArrivedDelegate(dataArrived);\n client.send("Hello World!");\n}\n\nvoid loop() {\n client.monitor();\n}\n\nvoid dataArrived(WebSocketClient client, char *data) {\n Serial.println("Data Arrived: " + data);\n}\n}}}\n\n!Examples\n\nThere example included with this library, EchoExample, will connect to echo.websocket.org, which hosts a service that simply echos any messages that you send it via Websocket. This example sends the message "Hello World!". If the example runs correctly, the Arduino will receive this same message back over the Websocket and print it via Serial.println.

!About \n\nNode.js package to access serial ports for reading and writing OR Welcome your robotic JavaScript overlords. Better yet, program them!\n\n!How To Use\nUsing node-serialport is pretty easy because it is pretty basic. It provides you with the building block to make great things, it is not a complete solution - just a cog in the (world domination) machine.\n\n!To Install\n\nThis assumes you have everything on your system necessary to compile ANY native module for Node.js. This may not be the case, though, so please ensure the following are true for your system before filing an issue about "Does not install". For all operatings systems, please ensure you have Python 2.x installed AND not 3.0, node-gyp (what we use to compile) requires Python 2.x.\n\n!Desktop (Debian/Ubuntu) Linux:\n\nYou know what you need for you system, basically your appropriate analog of build-essential. Keep rocking!\n\n{{{\n sudo apt-get install build-essential\n npm install serialport\n}}}\n!Raspberry Pi Linux:\n\nStarting with a a vanilla New Out of the Box Software (NOOBS) Raspbian image (currently tested: 5/25/2013)\n\nLog into your Raspberry Pi through whatever means works best and ensure you are on a terminal prompt for the remaining steps. This could be local or through an SSH (or a serial connection if you like).\n\nIssue the following commands to ensure you are up to date: \n\n{{{\nsudo apt-get update sudo apt-get upgrade -y\n}}}\n\nDownload and install node.js: \n{{{\nwget http://nodejs.org/dist/v0.10.12/node-v0.10.12-linux-arm-pi.tar.gz tar xvfz node-v0.10.12-linux-arm-pi.tar.gz sudo mv node-v0.10.12-linux-arm-pi /opt/node/\n}}}\n\nSet up your paths correctly: \n\n{{{\necho 'export PATH="$PATH:/opt/node/bin"' >> ~/.bashrc source ~/.bashrc\n}}}\n\nInstall using npm, note this will take a while as it is actually compiling code and that ARM processor is getting a workout. npm install serialport\n\n!To Use\n\n!Opening a serial port:\n{{{\nvar SerialPort = require("serialport").SerialPort\nvar serialPort = new SerialPort("/dev/tty-usbserial1", {\n baudrate: 57600\n});\n}}}\n\nWhen opening a serial port, you can specify (in this order).\n\n*Path to Serial Port - required.\n*Options - optional and described below.\n\nThe options object allows you to pass named options to the serial port during initialization. The valid attributes for the options object are the following:\n\n*baudrate: Baud Rate, defaults to 9600. Must be one of: 115200, 57600, 38400, 19200, 9600, 4800, 2400, 1800, 1200, 600, 300, 200, 150, 134, 110, 75, or 50.\n*databits: Data Bits, defaults to 8. Must be one of: 8, 7, 6, or 5.\n*stopbits: Stop Bits, defaults to 1. Must be one of: 1 or 2.\n*parity: Parity, defaults to 'none'. Must be one of: 'none', 'even', 'mark', 'odd', 'space'\n*buffersize: Size of read buffer, defaults to 255. Must be an integer value.\n*parser: The parser engine to use with read data, defaults to rawPacket strategy which just emits the raw buffer as a "data" event. Can be any function that accepts EventEmitter as first parameter and the raw buffer as the second parameter.\n\nNote, we have added support for either all lowercase OR camelcase of the options (thanks @jagautier), use whichever style you prefer.\n\n!open event\n\nYou MUST wait for the open event to be emitted before reading/writing to the serial port. The open happens asynchronously so installing 'data' listeners and writing before the open event might result in... nothing at all.\n\nAssuming you are connected to a serial console, you would for example:\n\n{{{\nserialPort.on("open", function () {\n console.log('open');\n serialPort.on('data', function(data) {\n console.log('data received: ' + data);\n }); \n serialPort.write("ls\sn", function(err, results) {\n console.log('err ' + err);\n console.log('results ' + results);\n }); \n});\n}}}\n\nYou can also call the open function, in this case instanciate the serialport with an additional flag.\n\n{{{\nvar SerialPort = require("serialport").SerialPort\nvar serialPort = new SerialPort("/dev/tty-usbserial1", {\n baudrate: 57600\n}, false); // this is the openImmediately flag [default is true]\n\nserialPort.open(function () {\n console.log('open');\n serialPort.on('data', function(data) {\n console.log('data received: ' + data);\n }); \n serialPort.write("ls\sn", function(err, results) {\n console.log('err ' + err);\n console.log('results ' + results);\n }); \n});\n}}}\n!List Ports\n\nYou can also list the ports along with some metadata as well.\n\n{{{\nserialport.list(function (err, ports) {\n ports.forEach(function(port) {\n console.log(port.comName);\n console.log(port.pnpId);\n console.log(port.manufacturer);\n });\n});\n}}}\n\n!Parsers\n\nOut of the box, node-serialport provides two parsers one that simply emits the raw buffer as a data event and the other which provides familiar "readline" style parsing. To use the readline parser, you must provide a delimiter as such:\n{{{\nvar serialport = require("serialport");\nvar SerialPort = serialport.SerialPort; // localize object constructor\n\nvar sp = new SerialPort("/dev/tty-usbserial1", { \n parser: serialport.parsers.readline("\sn") \n});\n}}}\nTo use the raw parser, you just provide the function definition (or leave undefined):\n{{{\nvar serialport = require("serialport");\nvar SerialPort = serialport.SerialPort; // localize object constructor\n\nvar sp = new SerialPort("/dev/tty-usbserial1", { \n parser: serialport.parsers.raw\n});\n}}}\nYou can get updates of new data from the Serial Port as follows:\n{{{\nserialPort.on("data", function (data) {\n sys.puts("here: "+data);\n});\n}}}\nYou can write to the serial port by sending a string or buffer to the write method as follows:\n{{{\nserialPort.write("OMG IT WORKS\sr");\n}}}\nEnjoy and do cool things with this code.\n

!Overview\n\nsnmpjs is a pure JavaScript, from-scratch framework for implementing SNMP agents, trap generators, and management applications in Node.js. It is intended primarily to enable the construction of a simple, general-purpose agent as an alternative to Net-SNMP.\n{{{\nvar os = require('os');\nvar snmp = require('snmpjs');\nvar logger = require('bunyan');\n\nvar log = new logger({\n name: 'snmpd',\n level: 'info'\n});\n\nvar agent = snmp.createAgent({\n log: log\n});\n\nagent.request({ oid: '.1.3.6.1.2.1.1.5', handler: function (prq) {\n var nodename = os.hostname();\n var val = snmp.data.createData({ type: 'OctetString',\n value: nodename });\n\n snmp.provider.readOnlyScalar(prq, val);\n} });\n\nagent.bind({ family: 'udp4', port: 161 });\n}}}\nTry hitting that with your favourite SNMP get utility, such as:\n\n{{{snmpget -v 2c -c any localhost .1.3.6.1.2.1.1.5}}}\n\n!Features\n\nsnmpjs allows you to implement agents, trap generators, and management applications that support the full range of SNMPv1 and SNMPv2c functionality. It is mostly compatible with all relevant standards -- see notes below -- and can also be extended to handle (and, optionally, to generate) SNMP messages that incorporate nonstandard data types and other deviations. Several pieces of standard MIB functionality are included along with a simple agent, but you can easily implement your own MIB subtrees or alternative agent. The library can also be used to incorporate SNMP functionality into other daemons; for example, to allow them to generate traps if a fault condition is detected.\n\n!Installation\n\n{{{npm install snmpjs}}}\n\n!More Info\n\nhttp://joyent.github.io/node-snmpjs/\n

http://www.tadiranbat.com/index.php/proven-in-remote-applications\n\nPulsesPlus batteries were developed specifically for applications such as automatic meter reading that require extremely long life at low average currents combined with periodic high current pulses. Marrying the inherent benefits of a standard bobbin-type lithium thionyl chloride cell with a hermetically sealed hybrid layer capacitor (HLC), they can be used to deliver pulses up to 3 A in amplitude and 380A/ s duration in a package no larger than two AA cells. By connecting these modules in series or parallel, a wide variety of voltages and capacities can be accommodated. The HLC is currently available in two sizes, all 15mm in dia. with lengths varying from 20 to 50 mm.\n\nThe use of hybrid lithium batteries enables Sensus Metering Systems to offer the industry's only published 20-year warranty\n\n\nAdditional benefits include:\n* Operating voltage of 3.6/3.9 V\n* Instant response/no passivation\n* Operating temperature range of ~40 C to 85 C\n* Hermetically sealed (glass-to-metal seal, laser welded)\n* 20-year operating life\n*Self-discharge <1.5% year\n* UL listed\n* Compliant with current shipping regulations\n

These are waterproof, scratch resistant, and UV resistant. They use a high efficiency monocrystalline cell. They output 6V at 930 mA via 3.5mm x 1.3mm DC jack connector - a nice upgrade to the 2W or 3W panels we have been carrying.

! Enclosure - Flanged (Red) - $7.95\n[img[https://dlnmh9ip6v2uc.cloudfront.net//images/products/1/1/3/6/6/11366-01.jpg]]\nDescription: These beefy, bright red plastic enclosures will give your widget the protection (and attention) it deserves. You've probably seen these used to enclose radio equipment or antenna baluns as they can be secured to a pole using U-bolts (not included). At about 3mm thick, this 74x158x90mm enclosure has plenty of space for gizmos, gadgets, widgets and doohickeys. The mounting flanges extend 19mm from either edge with two 50mm-spaced 7mm diameter holes.\n\nThere's a rubber gasket around the inside of the lid which forms a dust and moisture resistant seal when the screws are tightened down. The lid is secured with 6 4mm screws (included)\nhttps://www.sparkfun.com/products/11366\n\n!Chameleon Enclosure - Black - $29.95\n[img[https://dlnmh9ip6v2uc.cloudfront.net//images/products/9/6/8/2/09682-01b.jpg]]\nDescription: Designed and built by ESawdust in Colorado, Chameleon 1 is an enclosure for popular development boards including Arduino and many Olimex dev boards like the AVR-P28. It also supports the XBee Regulated and FreeWave MegaMini RF modules. What makes the Chameleon so great is its universality, and its ruggedness. At only 9oz, it's surprisingly light but can withstand being thrown across a parking lot.\n\nIn addition to the enclosure, Chameleon 1 Basic comes with one blank faceplate and stand-offs. The following specialized faceplates can be purchased separately:\n\n*Olimex AVR-P28 and AVR-P20 Faceplate\n*Atmel NGW100 Faceplate\n*Arduino Duemilanove Faceplate\n*Olimex SAM7-P256 Faceplate\n*ET-AVR Stamp Faceplate\n*FriendlyARM mini2440 Faceplate\n*Blank Faceplate\n\n\nUsing a 1/8" drill-bit, as referenced by the hole guide, holes are drilled so that the 1/4" standoffs can be mounted on the universal base plate. The pre-centerpunched holes (small dents that guide the drill so it doesn't skate) make drilling much easier. No measuring or tweaking is required. The hole pattern for the Olimex AVR-P28 is 80x100mm and is a very common board size. The Chameleon 1 base plate was engineered to accommodate a host of 80x100mm boards including most Olimex dev boards and the SparkFun Marsupial protoboards.\n\nChameleon 1 is made of a stiff, lightweight aluminum. At only 9.5 ounces (269 grams), Chameleon 1 is a ready-made, rapid-install, hard-shell enclosure for your system. Once assembled, the enclosure feels rock solid. Chameleon 1 comes standard with a powder-coated black exterior that can be used as-is or painted if desired.\n\nNote: The Chameleon comes with a single faceplate, but you will need another one to fully enclose the box. You can either get a blank faceplate or a specialized plate.\n\nPackage includes:\n\n*(1) Universal base plate\n*(1) Lid\n*(1) Board mounting hardware kit including 1/4" standoffs, screws and nuts\n*(16) self-cutting, self-tapping metal screws to securely attach the lid and faceplates\n*(1) Blank face plate (additional styles available separately)\n*(1) Hardware package includes:\n*(16) self-cutting, self-tapping metal screws to attach lid, base, faceplates\n*(4) 1/4" female/female standoffs\n*(8) 3/16" 4-40 screws\n*(4) 1/8" 4-40 screws\nDimensions:\n\nLid: 2 x 5 x 6.15"\nBase Plate: 0.40 x 4.90 x 6.15"\nWeight: 9.5 ounces (269 grams)\nDocuments:\n\nDrawings and Application Guide (3MB so you may want to right click and download locally)\nDrill locations\nhttps://www.sparkfun.com/products/9682

Frequency Based Interface design...\n\nThe problem with op amps in the strembot design are simply too much to contemplate.\n\nStatement of the problem:\nSince the pressure tape only operates between two resistances, low is 1000 ohms and hi is 2000 ohms. Rather than try to express this resistance as a change in voltage, which leads to \nall sorts of level shift and zeroing issues, it is better to express the tapes resistance change in terms of a frequency change. The following circuit expresses this change as a \nsquare wave between 25 and 35 kilo Hertz. \n\n[img[http://docbox.flint.com/~flint/strembot/ainfr2_2014-03-010b_schem.jpg]]\n\nI hope that all this is helpful to understand this is a better way to go than try\nto do this in the amplitude domain as I have [[tried already|ADCop-AmpDesign]].\n\n\nArduino Frequency Counting Resources:\n
