Kratky Hydro – Round 2

Going to keep this one short and just archive some pictures. This tub contains 6 bok choy cubes and 3 lacinato kale cubes. Same nutrient solution mix but now the system is outdoors with around 1000 lumen (bright shade) of light. Also trying some hot peppers to see how they’ll do! Enjoy!

Foundations of a Plan

Spinning my Wheels

Off and on, I’ll feel like I have majority of things figured out in my head. Then a week or two down the road, I’ll forget what things I had figured out and try to re-figure them out. Seems like a pretty inefficient cycle. I do well with visuals since they seem to help minimize the impact of my lack of short memory when trying to remember a lot of information, ideas or anything else of substance. Memes though, those just stick for some reason…

Pokemon Trading Card Reader

I have a few Pokemon cards. Actually a ton. It’s hard to know what I’ve got and which cards might actually be worth a bit of cash. OpenCV + Ebay’s handy API could prove to be useful to help provide the information we’d like! Would also work as a nice way to organize and catalog what I have.

LED Wake Up Light – Jan 2017 Update

I accidentally fried my electric imp a while ago which lead me to investigate other alternatives for WiFi connectivity. I happened to have a spare Raspberry Pi model 3 B+ from another project and decided to use that as my means of controlling the LED strip over WiFi.  Along with these updates, I swapped my UA741 for a slick TTL MOSFET which works much better – simplifies the wiring as well!

Hololens Development

Playing Around with the Hololens

Augmented and virtual reality are fun and fascinating areas of interest to play around with in regards to software. A lot of limitations that we have with our eyes goes away pretty quickly when you add in an augmented reality platform to the visual mix. From thinking of ways to see through the ground when dealing with horizontal directional drilling to seeing through buildings during combat scenarios, AR and VR will be changing and improving how we deal with tasks that heavily rely on vision and visual queues.

Solar Charger Circuit

The Beginning

I’ve been interested in renewable energy for a while now. This past Spring during my trip to Kuala Lumpur, Malaysia, I picked up 2 solar panels that could provide 10 watts of total power under optimal conditions. Oh, and they were only $30USD. Now I have an excuse to start generating my own power!

My goal was to be able to charge a 12V battery that would then be able charge 5V USB devices. There we a few things that I had to keep in mind.

LED Wake Up Light

Now that I’m out of school and working full time, waking up during the fall/winter/spring is getting pretty difficult. It was no problem at all during the summer since I was able to wake up with the sun. That’s no longer the case as the winter months approach. So how could I set up something to try and recreate the sun rising? Hopefully a strip of white LEDs next to my window will do the trick!

Senior Design

For my senior design, we were to develop an automated chess set that would be able to play against a human while looking like another, “invisible”, player was competing against them. We came up with a concept similar to the following video:

Autonomous Maze Navigation

The final project for CprE 288 consisted of developing software to allow for our iRobot to navigate through a maze by only using readings from infrared, sonar, cliff, and bump sensors. With limited forms of sensing, our team decided to have me develop a GUI to better help us navigate the maze. Using the Processing IDE, I developed the following GUI

8×10 LED Matrix

My groupmate and I both had a deep interest in how LCD screens, TVs, or any sort of display, worked. We decided to look into these devices a bit more to see what we could come up with. After doing a good amount of research, we came upon the basic concept of an LED matrix. We thought this would give us good insight into how a basic display functioned and was constructed.
