Got a few more things in the mail, today. The package contained mostly robot parts and the mycorrhizal fungi for the hydroponic system. Lots of research going on multiple subjects, I found that changing the subject that I’m researching helps me focus better and lets the information organize and take root in my brain better and faster. It also allows for time for more questions to form and answers to questions on other subjects to form.
Hydroponics or just more research
I’ve been researching indoor grow tents, and it seems that the main advantages for an indoor garden are:
- Maximize Light Efficiency
- Local Environment control such ambient temperature and humidity
- Keeping pests out
- Controlling smells
- Containing allergens
The main factors that a grow tent needs to have is a reflective inner surface that is non-porous that is supported by a rigid frame. Yes, there are lots of commercially available choices to choose from, but this is not a commercial venture and is being done on a budget, rather severely limited at the moment at that.
My idea is to use PVC pipe for the frame and solar blankets for the covering. The PVC should be rigid enough to hold up the Mylar sheets and provide a stable enough frame to hold the LED lamp. The Mylar sheeting that the solar blankets are made out of is very light and highly reflective on one side as far as light and heat go, I have used them while camping in the Spring and Fall when night time temperatures can change dramatically and they don’t add much weight or bulk to a pack. Solar blankets are super cheap, so it fits within the budget constraints, as well. I did a bit of research on the price of the connectors for the PVC pipes and they would cost more than a roll of filament, even during this pandemic crisis. So oh deary me, what’s a geek to do?(This is blatant sarcasm) So, I will have to design and print out connectors for the grow tent, good thing I have a functional 3D printer.(Not so blatant sarcasm) It has been printing ‘bot parts and pieces for the Cyclone PCB factory of late, so a change in tasks would be a good thing.
Robotics for the win!
Speaking of ‘bots, I’ve been printing out and assembling treads, a lot of late. Yes, wheels are simpler and have the advantage of cost over treads, but treads are easier to control, compensate for and last way longer than wheels, plus are way cooler. I did find an early copy of my robot control library for the Arduino, so that is a boon in of itself. Treads also allow you to keep a lower center of gravity, thus making a very stable platform that increases the reach of a robot’s arm or other mechanical appendages. Platform stability is very important for most robots, it not only allows you to pack electronics, actuators and batteries into them, but you have less code dealing with how to get the robot back on it’s means of locomotion. Speaking of electronics, let’s move on to the PCB mini factory.
Cyclone PCB maker to the rescue!
Well, actually not yet and maybe not for awhile. It is coming along quite well, though. It’s at the point that I am going to start putting it together so that I can figure out what I am missing and also can get ideas of what I want to add to it or change. I really should go through the parts bins to see what I already have, because I know that I have lead screws, smooth rods, bearings and a RAMPS kit 1.4 in there that can be used for the PCB maker. It’s a good thing that I usually salvage dead projects and pick up useful items when I find them for a good price.
Some notes on creativity
I’d like to take some time and write a few things about being creative. It may seem a bit disjointed, but each part is a thought and therefore complete in of itself.
I really don’t like reinventing the wheel for every project, it becomes tedious and does suck the joy out of me to do that over and over, plus it’s truly a waste of time that could be used to create more advanced and quality code and better physical designs. This makes more time for other projects or time to do things such as improvements and decorative work.
Grander objects tend to impress others way easier and give a greater amount of accomplishment to the creator. By making something grander than it has to be, doesn’t have to be about scale, but can be a better design, higher quality materials or even just adding some flourishes to an object to make it more appealing to the eye.
Work on projects even if you don’t have all the parts. Parts can found or bought later, and you may find a better part than the one that you thought that project required. For the PCB factory, I was going to use a Dremel like a lot of people who have made such, but I found an actual spindle that was designed for use in a CNC machine for etching and carving a variety of materials. It will be way easier to control since it’s a DC brushed motor and is the correct tool necessary to do the job.
Choose your projects wisely, keep the number of what you are working small, but greater than one. Don’t hoard projects for some day, because the best day to work on things is today for tomorrow never comes.
There is a huge difference in buying parts and tools for future projects and buying such to just have them for the purpose of merely possessing them. The former is planning for the future, the latter is merely hoarding. If you know that you use certain things a lot and find them for a great price, if you have the means than purchase them at that time. Already having the parts makes shopping for what you need easier, makes projects come together faster and sometimes depending on your network of people you can trade for things that you need from your own stock of parts.
