h1. Hardware Links * "Raspberry Pi":http://www.raspberrypi.org * CHiP * [[ESP8266]] ** "ESP Open SDK":https://github.com/pfalcon/esp-open-sdk - open source SDK for ESP8266 ** ""NodeMCU":https://github.com/nodemcu/nodemcu-firmware - lua based firmware for MCU like ESP8266 *** This has links to "esptool":https://github.com/themadinventor/esptool for flashing firmware to device ** "ESPlorer":https://github.com/4refr0nt/ESPlorer is a Java IDE for the ESP8266 ** "Arduino core for ESP8266":https://github.com/esp8266/Arduino - look under doc for libraries, etc. ** "ESP8266 Arduino forum":http://www.esp8266.com/viewforum.php?f=25 ** "Loading Firmware":http://www.esp8266.com/wiki/doku.php?id=loading_firmware ** "Getting Started":http://www.esp8266.com/wiki/doku.php?id=getting-started-with-the-esp8266 ** "Getting Started":http://rancidbacon.com/files/kiwicon8/ESP8266_WiFi_Module_Quick_Start_Guide_v_1.0.4.pdf pdf (different version) ** "AT Commands":https://room-15.github.io/blog/2015/03/26/esp8266-at-command-reference/ *** "Get MAC address":https://room-15.github.io/blog/2015/03/26/esp8266-at-command-reference/#AT+CIPSTAMAC ** Examples *** "One Way Chat, part 2":https://www.youtube.com/watch?v=iRMdj3dS2hc shows how to connect basic hardware (somewhat limited) and program to run as a web server using stock programs. *** "HTTP I/O":http://www.instructables.com/id/ESP8266-HTTP-IO-Server/ is a "library":https://github.com/jscottb/ESP8266_http_io that gives direct access to GPIO pins. This is essentially what we'd want except it needs to be "wrapped in a security layer":http://www.esp8266.com/viewtopic.php?f=23&t=3929 of "some kind":https://github.com/mziwisky/esp8266-dev/blob/master/esphttpd/user/auth.c. h1. AC Control # TRIACs: Low cost, high current handling capability. # Traditional relay: moving parts, relatively low cost, very high current # Solid State Relay: Higher cost, no moving parts. Advantage over TRIACs is that SSR can interrupt current at any point in the AC waveform. TRIACs only cut off current at the zero-crossing point. h1. DC Control TBC h1. Stepper Motor Control # TI DRV8811: Integrated FETs, up to 1.9A per coil http://www.ti.com/lit/ds/symlink/drv8811.pdf # (Toshiba?) TB6612: Used on adafruit and other boards: https://www.adafruit.com/products/2448 Documentation/sourcing appears limited
