Research interests: Current research interests are desalination (turning salt water to fresh) trying to improve this process so that it becomes more viable for the world
First semester
8/23/23
First day of my junior year, I want to start working on turning salt water into fresh water to help the world and help people with limited access to fresh water. Currently, I’m looking into improving the efficiency of power and heat that is needed to make this process happen. As water is a very limited resource and many places in the world don’t have access to fresh water this is very important
Second Semester
January 2, 2024
I focus on finding a new 3D printing nylon filament and looking at the fine-tuning precision that helps increase the accuracy and sustainability of printers.
My other goal is to find a new research question for my desalination lab. This is because I want a testable scientific question that will create more meaningful research.

I have found that mushrooms might be a good source for desalination; they are commonly used in the process of gray water purification, and the University of Riverside has been studying these mushrooms
Mushrooms of interest:
The Salty Agaric, Agaricus Bernardii
Shiitake mushrooms
Mycelium

Today, I cleaned the ultimate s5 extrusion box and increased the pressure that grips the filament.
This implementation proceeded to fix the extrusion issue, after increasing pressure, one calibration dragon was printed, and two miniature rotors were printed, these three parts were the most sturdy and stable I have seen so far. Following this, 2 large rotors were printed on a different filament, but this print failed. However, the first half of the print is almost perfect, being very strong and clean with some minor slight issues. The issue only started on both parts at about halfway up. This leads me to three hypotheses, one is that as it got later into the night, it started to get colder and caused the print to have temperature inconsistencies, and these thermal issues led to layering issues. My other hypothesis would be that as the filament was left out, the longer it sat, the more hydrated it got. My last hypothesis would be that during the night, a recorded earthquake created layering issues and led the entire print to fail. This could totally lead to a large-scale failure. Another thing to note is that the extrusion box was full of yellow filament shavings and was eating away while in the extruder. The next thing I would like to test is utilizing the dehumidifying box to see if it will improve the quality of our prints, if it does, this would mean that the WISRD lab is too humid for successful, consistent printing. If this implementation shows nothing and after changing this filament, no change is made, then the problem is the temperature in the room later in the day.

Today, I learned about the hydroponix system and recorded information for leaf quantity and total height of the plant using a set of calipers. An overflow started while adjusting the middle row due to issues with the hydroponics flow rate. Additionally, I worked on disassembling the Ultimaker print core as the WISRD Lab has been using them up and having significant jams/issues with nozzles for multiple months. I learned how to disassemble and clean the print core properly and believe I now know how to extend the life of each core tenfold.

This week, I started researching a new interest of mine, lab-grown produce that is acceptable for consumption. So far, I'm looking at different ways of producing a sustainable food source. At first, I looked at 3D printing. However, this printing is more entry-level to the idea of sustainability, and what seems to be a much more promising future would be growing our own cultures of cells using plant cell structures such as synthetic salmon.

Today, I began the assembly of an Ultimaker s5 hood. This will help with temperature regulation and help reduce the amount of dust that is getting into the Ultimaker s5 and should reduce total print failure. Additionally, Bob mentioned using electrolysis to separate the hydrogen and oxygen from saltwater. This is a very promising idea for desalination and could be an exciting collaboration with reverse osmosis. Another idea is looking at toroidal propellers in air vs. water, I also looked at new ideas for hydroponics, one idea of getting sound from plants that are growing in the hydroponics tank and comparing levels of salt within the water and how they
Change their sound output with the different living conditions. Another fun experiment to test would be how water and air plants' oxygen levels change their growth. Two ideas for testing this would be Using/creating oxygenated water or adapting the hydroponics chamber into a hyperbaric hydroponics chamber

Looking further into 3D printers, focusing on the Bamboo Labs x1e, this printer uses advanced technologies and AI, making it stand out from many other printers. Bamboo Labs has been striving most in the field of 3D printing and creating advanced printers at lower prices. This printer is a strong choice for upgrading our current printers or purchasing new printers for the coming school year.

Looking into ED desalination and prototyping a system that I will be able to show during the poster session
Apr 8, 2024
Today, I took a deep dive into MIT's previous papers, patents, and journals. This research led me to find a paper that covers all of the desalination and will significantly aid my research and help me begin Sketching future designs to build in WISRD. This Paper is so significant as it studied the ability to extend the life of solar desalination filters, both reducing required maintenance and increasing overall efficiency.
April 11, 2024
Began researching designs for DIY air control systems for 3D printing. Following this research, I started taking measurements of our Ultimaker 3 as this printer needs to be very temperature-controlled and humidity-controlled. This air filter will help increase the safety of 3D printing in WISRD, as possibly harmful Materials can be printed in a controlled chamber.

Preparing hydroponics chamber for first growth cycle, reinforcing the roof with new structural beam to strengthen roofing panels. Looking into adding two fans to increase the air circulation of hydroponics reducing stagnant air.
September 6th
The roof of the hydroponics has been rebuilt and strengthened; additionally, after researching 3D printers, WISRD has decided to Purchase a new Bambu 1xe. I have also joined the Robotics lab led by Jacob F. and will be helping him with code and overall building. Trying to diagnose the problem within jacobs code, I noticed that his code is 3dprinter code that has been repurposed. Seeing how large this code is and how a lot of it is not required for the jacobs project, I have decided to attempt to code it from scratch while teaching myself the marlin code he already has been using. Additionally regarding hydroponics, I have began making a full sensor list that will alow hydroponics to collect more data including live data for plant mass.
September 11
Today Nikita and I met discussing the future of hydroponics. While discussing we decided that Nikita will find an improved Flow sensor that we will use to determine if hydroponics has loss in water or if hydroponics has noticed a clog within one of the pumps. This data will be used to shut off the hydroponics pumps, ensuring that we do not damage our systems and risk electronic issues. Additionally, we discussed the roofing nikita added and decided that instead of just laying a cloth overtop we will build a frame that the tarp will staple onto and then this frame can be placed on top of the hydroponics system allowing for easy removal and adjustment. Lastly, Nikita and I discussed how we can improve the Hydroponics systems, we decided that mounting the electronics to the roof beams will protect the longevity of our systems, additionally, we plan to add an overflow section to hydroponics where any spilled water will be funneled into a collection chamber.

Today I began designing the lid for the hydroponics system. Currently, I am planning on using 2 1x4s that are 61.5 inches in length, and two 1x4s that are 55.5 inches in length. To strengthen the structure I will use 4 L brackets the ones I’m currently looking at are linked below.

Today we began to try and begin the hydroponics cycle. During this process, It became apparent that hydroponics needs a lot of work before we begin running a plant cycle, when trying to start it became apparent that the PVC structure had never been sealed, the system for controlling water level was poorly designed and the electronics had been positioned in direct position to get spilled on. While looking into possible solutions I the idea of redoing the hydroponics system following improved designs came up and quickly became our next plan. After looking into types of hydroponics systems we decided that to best utilize our resources and previously acquired data we will continue to use an NFT (Nutrient film Technique) Hydroponics system. Additionally, if we decide to replace the current hydroponics growth tubes, we must use intransparent pvc to help prevent against algae .
This is an example of an NFT hydroponic system being set up on a larger scale.

Dark matter day working with Noam and Johna, running the Hoffman apparatus
October 28
For the past month, I have been heavily working on researching hydroponics and preparing for dark matter day.
On dark matter day, I ran a Hoffman apparatus successfully, separating hydrogen from water and oxygen. During the operation of the Hoffman apparatus, we struggled to achieve successful oxygen collection, and we later realized that the oxygen was bonding to our copper anod , this was causing rapid oxidation, decreasing our production of hydrogen and oxygen.

for the past week, I have been Cadding and designing new hydroponics tubes and figuring out the dimensions of our new tubes
November 13th
I have been researching other hydroponics designs and looking for scientific research papers; I found a source online from a YouTube channel called “Hoocho,” which seems to use research to maximize hydroponics homesteading. We have gotten access to his Patreon to access his cad files and hydroponics kits tools and designs
November 15
After doing research and looking at different research and nonresearch texts, I have chosen to purchase Hydroponics Food Production 8th edition by Howard M. Resh. This book seems to be the most updated and widely accepted. I will be pausing hydroponics development until this text arrives so I can use it to
December 4th
The new hydroponics book is fantastic, and I have found multiple designs for hydroponics systems as well as solenoid balancing tanks, I have ordered hydroponics channels that are rectangular instead of circular that will alow for a more shallow flow, meaning less water needs to be used. The tubes i ordered is one nursing tube that can hold 24 plants and 4 growth chambers that can each hold 6 tubes. The tubes are 52 inches long so currently i am needing to expand the hydroponics frame to fit a larger scale hydroponics system. The next parts i need to order will be the Irrigation tubing, pumps, and build the frame for the new tubes
December 6th
Today, I planned out the next week of hydroponics. Currently, the goal is by Monday, the 9th of December, and I will finish the hydroponics lid; earlier during that same day, I would like to begin setting up the irrigation tubing. Later today, I am expect to receive my new NFT channels and would like to begin setting those up looking at making the frame to support the 5 tubes.
December 12th
Last night, I finished my poster for the poster session next Tuesday. Working with Nikkita, I wrote a new abstract about the progress of our lab so far this year. Today, I began setting up the new hydroponics chambers, we can go from 9 plants total to 48 and also can reduce water and nutrient waste.
December 20th
This week, I built a new frame for hydroponics, had Jacob start zip-tying tubes down, and had Noam cut a two-by-four into segments to place under the, had amy and jacob cut an old hydroponic tube into segments that will be used for hydroponics is making good progress
