  • 11:0811:08, 8 December 2024 diff hist +10,976‎ N AVR web scraper ‎ Created page with "This project is an intro to web scraping using an AVR and lantronix ethernet module. The idea here is to connect to a web server, scrape a specific page, parse everything on it to find the desired data and do whatever I want with said data. In my project I am scraping temperature data to display in a (somewhat) fancy wall decoration. Every hour it will get the temperature from the webpage and update the 7 segment display. This was a present I made for my Mom who moved..." current
  • 11:0811:08, 8 December 2024 diff hist +4,714‎ N RGB driver ‎ Created page with "==Abstract== This project was for a Halloween prop wand. A tiny circuit board with a AA battery pack and RGB LED was held in the hand with a ~10" acrylic light pipe to pose as the wand. The wand had 4 modes. RGB cycle mode - The wand cycled through the RGB color spectrum slowly fading into surrounding colors. Color lock - Locks the wand onto the currently displayed color. "Tink" mode - The wand slowly pulsates a tan color, much like what you would picture Tinkerbel..." current

It uses a strand (or 2) of individually addressable RGB LEDs. The LEDs have a WS2811 driver IC which communicates using 1 wire serial. This is NOT to be confused with the WS2801 which is a 2 wire serial IC, and quite frankly a lot easier to work with. Luckily though, people like [http://bleaklow.com/ Alan Burlison] have already done the hard work for everyone and have been..." current

I originally make my own PCB to control the cannon. My day job approached me a month ago and asked If I would present something to a local elementary school for the Great American Teach-in Day. I converted this machine to be controlled by a Allen-Bradley CompactLogix PLC for that demonstration. This is that program. It makes use of the new user defined instructions a..." current

Ping Pong Scoreboard! --Paul 13:16, 10 January 2008 (EST)<section end=updates /> <section begin=oldnews /> <section end=oldnews /> ==Abstract== This device is intended to make score keeping easier and more spectator friendly for the game of ping pong. It consists of 2 double digit 7-0segment displays, 1 display for each player. Each display has 5 LEDs that are used to indicate the player’s current serve. The d..." current
  • 11:0711:07, 8 December 2024 diff hist +829‎ N Omron NB HMI and Allen-Bradley CompactLogix example ‎ Created page with "I had a difficult time with this due to the lack of support from Omron, lack of examples, and questionable documentation for this procedure. Hopefully this will help others who had the same issues as I. This is a example project showing how to pass variables from the PLC to the HMI over RS232 DF1. It shows how to pass all the supported data types by the HMI; INT, REAL, and BOOL. I am using an Allen-Bradley L31 CompactLogix and a Omron NB7W-TW00B HMI but anyone using a..." current

I will probably be getting some Xbee pro modules soon to try and compensate for this. The device's operation is just hit and miss with the current setup. Ive tried implementing several solutions to compensate for this but all of which were unacceptable. Im putting this project o..." current

It is still a work in progress!''' --Paul 20:27, 14 February 2013 (EST) I stumbled on this lovely old school Fluke Nixie tube DMM. After waiting for a bit I was able to pick one up cheap, the only problem was it was not working. Well sort of. The DMM did not function but the Nixie display seemed to work fine. The great part about old lab instruments is that the schematics were all public and published in tech manuals. G..." current
