RGB Internet Pumpkin



Just in time for Halloween, I modified my previous Raspberry Pi Internet LED Control project to control an RGB LED, and stuck it inside a fake pumpkin. Now I have an internet controlled RGB pumpkin!

Digital Picture Frame with Animated Gifs


The problem with old computers is trying to find a use for them after you have upgraded. I found myself owning four different laptops. Along with my tablet, phone, and desktop, I didn't have use for so many laptops.

Astro Star Projector Kit Build


Recently I heard about the Cloud b Twilight Constellation Night Light, which is a stuffed turtle that projects stars from it's shell. I considered ordering one, but first I searched for a cheaper star projector.

The cheapest one by far is Astrostar Astro Star Laser Projector Cosmos Light Lamp, at just $15. The pictures look amazing. However, the reviews are something else.

Toolbox Boombox


While I was home for winter vacation, I quickly grew bored without access to my electronic tools and projects. To entertain myself, I took some speakers, and amplifier, and an empty tool case and combined them all into a boombox.

Raspberry Pi Visual Ping Indicator / Roommate Tracker


A frequent problem in my apartment is the lack of a consistent sleep schedule among my roommates. It's hard to tell when someone is asleep in their room, and when someone is gone and their door is closed. One of my roommates made a joke that I should build a device to track who is actually present in the apartment. So I did.

PCB Design Process


My Raspberry Pi Temperature Monitor Project was pretty cool, and I was getting some neat data from it, but I wanted to take it to the next level. This included using modern temperature sensors and building a printed circuit board (PCB) to replace the breadboard in the old project. In this post I will discuss my PCB design process.

Monitoring Temperatures Using a Raspberry Pi and a MCP3208 ADC with Thermistors



After my Raspbery Pi Internet LED Control project, I wanted to try reading sensors from my room on to the internet. The only sensors I had around were thermistors, a type of resistor that changes resistance based on the temperature.
