This is a much more refined version of that graph I created earlier. This one is much more detailed, and the sizes of the graph can easily be controlled with the imageSizeX and Y Vals. This program will render: <?php /* CAT:Scaling */ /* pChart library inclusions */ include(“/srv/www/lib/pChart/class/pData.class.php”); include(“/srv/www/lib/pChart/class/pDraw.class.php”); include(“/srv/www/lib/pChart/class/pImage.class.php”); $imageSizeXXal = 1000; $imageSizeYVal…

Again, short post. This php code: <?php session_start(); require_once “/srv/www/lib/pChart/class/pDraw.class.php”; require_once “/srv/www/lib/pChart/class/pImage.class.php”; require_once “/srv/www/lib/pChart/class/pData.class.php”; $squareSeries = array(); $cubeSeries = array(); $fourthSeries = array(); for ($i = 0; $i <= 4; $i++){ $squareSeries[$i] = pow($i,2); $cubeSeries[$i] = pow($i,3); $fourthSeries[$i] = pow($i, 4); } $myPowersData = new pData(); $myPowersData -> addPoints($squareSeries,”Square”); $myPowersData -> addPoints($cubeSeries,”Cube”); $myPowersData -> addPoints($fourthSeries,”Fourth”);…

As this post is more of an update, I won’t be adding any explanations, just giving the python code. This will read 3 values from the adc and put them into the database “adc_database”. It will put them in the table “adc_input_data_4” in the columns “Channel_1″,”Channel_2” and “Channel_3” respectively. #!/usr/bin/env python # -*- coding: utf-8…

The first revision of this project was shipped in November of 2020, but the subsequent redesign was commissioned and completed the following summer in 2021. This post primarily a journey through that second revision, and it’s publication comes some time after the deliverable was shipped to the client. Engineering requirements that arrive downstream from artistic…

Greetings from WPI! Here’s a video: Desperate times call for desperate measures. I recently found out that a club at my school is essentially a hackerspace equipped with 3D printers so I could finally print enclosures for the PiPlanter and the DSFU. But that means I would need to finial the designs for both of…

Here’s a video of the system working: I wanted to create a way to push data from my Raspberry Pi monitoring plant growth to myself. Instead of creating an email server and sending emails, or setting up an sms client, I decided to install tweepy and use twitter and python to send me the data. First thing’s…
