Topology Optimization Using ToPy

For a while now, I’ve been interested in how machine learning could be applied to designing and optimizing CAD solutions. Here’s a promotional video of Autodesk’s generative design tool which will give you an idea of the possibilities.

ToPy is an open source topology optimization toolkit written in Python that allows a developer/designer to quickly define a problem and optimize it to fit within constraints such as minimum compliance / maximum stiffness. In this case, I’ll be looking at a maximum stiffness problem with the goal of creating structures that use the least amount of material while still maintaining maximum stiffness.

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…

Simple Hydroponics – How to put together a simple Kratky system

Our Kratky System

I want to keep this short  – so if you’re curious about how things went for us, here’s some photographic evidence of how things are going so far!

Hydro Update – 4 Day Time Lapse

I ended up printing out a case for the GoPro so I can attach it to a small tripod that we’ve got. Definitely improves the view of everything when running a time lapse. What’s really cool is watching the center area of the lettuce to see new leaves slowly form! They also seem to explode in growth overnight.

Grow Light Controller – Update

As a little addition to my previously discussed Grow Light Controller, now when the lights turn off, I have a fan kick on to help circulate the air around the leaves at night! Check out the latest changes on Github!

Grow Light Controller

We’re going to be out of town for the weekend and a problem arose when we started thinking about how to turn on the lights for the hydroponic setup. Using a relay controlled power outlet that I whipped together for another project + a C.H.I.P., I was able to easily port over the code I was using for my Wake Up Light (check it out) for use in this system.

Kratky Method Hydroponics

Cheryl and I decided to start growing some lettuce, basil and spinach hydroponically just to see what would happen. Of course we hope that we’ll be able to enjoy a fresh salad straight from our system, but we’ll see if that happens.

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!
