A little background: I’ve been building and tinkering with computers since I was about 12, when I got my own laptop and desktop both from garage sales and began swapping parts, doing OS upgrades from floppy disks and doing whatever I could to tinker with them. Fast forward almost two decades, and I’m still at …

Offsite backups 101
I’ve learned some hard lessons in the couple decades of tinkering with computers. One of the biggest is data loss. Like everyone else, I didn’t worry as much as I should have and it cost me…
New Year, New Car? Or DDoS Fun?
Started off 30 minutes into the new year by hitting black ice and completely annihilating my favorite car. Thankfully safe but Eris didn’t make it. Now for the DDoS fun…

Arduino Wireless Logging, Post Four: The Graphs
When I got all this data logged and running, I wanted an easier way to show data than spreadsheets or queries. The end goal was actual graphs to show trends and what not. Introducing “phpgraphlib”. This is an open source piece of code built to implement charts/graphs into webpages with ease. This took a bit …

Arduino Wireless Logging, Post Three: Mysql, PHP, and a little networking
Here’s where things started to get a little more complex. At this point, I have a wireless system to transmit data from multiple nodes to a central hub (node0) which collects and shows the data via serial connection. The general idea/goal is this: Arduino Nodes send data to central node Central node is connected to …

Arduino Wireless Logging, Post Two: The Design
This is the second part of the series for my Arduino wireless project I’ve been working on for a couple weeks now. You can start reading from the first post: https://aasullivan.com/?p=1146. We have the idea, now we have to build it. I have three Arduinos set up at this point in this manner: (1) Set up …

Arduino Wireless Logging, Post One: The Idea
I’ve had a number Arduino systems for some time now along with a large number of RF24 wireless modules and DHT11 humidity/temperature sensors. The idea I’ve had for some time is this: Arduino with a DHT11 sensor and RF24 wireless device pull then transmit data. Data goes to secondary hub/master Arduino using an RF24 module …

Arduino Home Monitoring
Lately I’ve been engrossed in a project to add some monitoring to my home. This includes temperature and humidity readings, along with monitoring for windows and doors eventually. This will be built almost entirely using Arduinos wherever possible. The Goal: To have a remotely viewable home dashboard to monitoring the house The Plan: Use Arduinos …
Latest Computer build: RAID fileserver and media center
Had the idea in my head for a while now about doing a fileserver build to put all my media in one place. This includes years of movies, music and TV shows along with about 100GB of music rips. The goals of this were pretty simple: Have some form of redundancy, most likely in a …
