Capturing Serial Data from PROTEUS Designs Sometimes, during the design process it is advantageous to capture serial data from the design under simulation. The ISIS simulation environment contains a couple of external simulation devices that allow the design to interface serially. Using a GPL null-modem Windows COM driver enables host capture of the design data. Continue reading
PIC-based PID Motor Control Proteus Simulation II This project is a formalization of the previously posted motor control project. The primary difference is that the code has more product features. The architecture of the control loop attempts to account for the expected lag time of the real world motor. Continue reading
PIC-based PID Motor Control Proteus Simulation This project was assembled in order to experiment with a PID algorithm for an engine control project. The Proteus based simulation was useful for debugging and tuning the time base and mathematics of the control equation. For this project, the control code was done using Sourceboost BoostC. I've included a bit of a rant regarding MikroC and Labcenter in the project text. Continue reading
PHP Google Analytics Example Having a new website , one has access to all the statistics Google Analyticator provides when installed in your Wordpress plugins. Making a Google Analytics account enables you to have Google mash all the data for you in various formats. Continue reading
PHP jQuery AJAX-based Stock Quote retriever This version of the original CodeIgniter jQuery AJAX-based Stock Quote retriever project has a few modifications. Continue reading
PHP based IP Resolution Tool Before I figured out how to configure AWSTATS to resolve ip addresses, I put together this PHP program to resolve addresses in the log file. Continue reading
CodeIgniter jQuery AJAX-based Stock Quote retriever This Code Igniter example project uses jQuery-based AJAX to retrieve stock quotes from YAHOO finance. Its a small example that sets up a matrix of stocks and continuously updates the data using jQuery.post() calls to a backend PHP helper. Continue reading
Sparkfun Reflow Toaster Oven in Proteus This project is a Reflow Toaster Oven Controller kit from Sparkfun. I built a Proteus simulation and schematic. The provided hex code operates in the simulation. Continue reading
Hello world! Welcome to the Project Place.  This site is new and active thx
Proteus Example VSM-Analog/Digital Model This Proteus VSM example combines the first two examples into a VSM model that has both digital and analog inputs. The net result is a device that animates a 4-LED bar graph based on an analog input pin while producing programmatic logic on it's digital output pin. Continue reading
Proteus Example VSM-Digital Model This example VSM builds from the previously posted ACTIVE Model example. The digital model retains the analog input pin while adding two digital inputs and one digital output pin. However, by adding the digital interface, you’ll find that the analog … Continue reading
Bank Scraper Guru employer was looking for a utility to scrape a site that maintained bank information. Typical information included, name address, city, etc. The proposal example utilized PHP Simple HTML DOM. Continue reading
Auction Scraper Guru employer was looking for a utility to scrape an auction site, swoopo.com. The proposal example utilized PHP Simple HTML DOM. Continue reading
Proteus Example VSM-ACTIVE Model This project is an example VSM ACTIVE model for the Proteus simulation tool. The example builds from the SDK VSM MODELING TUTORIAL. Instead of the numeric voltmeter, this example lights 4 distinct simulated LED bars. The test circuit directly drives a 5V sine wave into the analog input pin. Continue reading
