This week is very crucial for completing my vein finder. This week, I am assembling my vein finder and printing my directions paper to go along with it. Before I get to the assembly of my vein finder, the directions paper is complete. On the paper, I put the logo of my product. This logo has a hand on it, showing their veins, with a tree growing through it, being symbolic of how this vein finder helps grow your ability to see your veins. There is also a reasoning and explanation of everything the vein finder shows, such as using the infrared light and why it is so effective. Hopefully, the ease of using this document and the convincing information from my research will convince any consumer to use it. Along with a three step process of using my vein finder, there is also space for me to put pictures of my vein finder. This leads to the state my vein finder is. My vein finder, today (May 7, 2018), is still in the process of being 3-D printed. It is a complicated story, but the Harris County Public Library (Freeman Branch) does not have the person in charge of the printer present until Tuesday, May 8, 2018. Also, a friend (Ibrahim Islam) offered me to use his 3-D printer, so my three parts will be divided between these two printers. My vein finder will have its parts printed by Friday, May 11, 2018. Once Saturday, May 12, 2018, comes around, I will officially begin the assembly of my vein finder at the League City location that I described at one of my previous blog posts. Also, two of my father's friends have offered to help me, so I will probably ask all of them to come to the League City place, so we can wrap our heads around assembling the vein finder. I do not plan for the vein finder to take more than one day, so my vein finder will be done by Sunday! This process was honestly really difficult. I called three places for 3-D printing, but I got denied all three times because my product is not professional enough. My product is not professional enough, not because of the design, but because of the fact that this is being printed by a teenager and not a big company. All in all, I am on track on finishing my vein finder.

Last week, Mrs. Hutt was absent on the days I wanted to print my vein finder using the 3-D printer. This week, I hope that she is there, so I can print. In the case that she is still not here, I will go to a facility that has a 3-D printer. That option is highly inconvenient because according to what I researched, a store in Kirby is the closest to my house. Going forward, my parts have all arrived, and I plan to unbox them this week. I really only have the assembly of my vein finder remaining in my main project. Hopefully, this weekend, I will begin assembly of my vein finder. This is very unlike due to the fact that I have three parts to be 3-D printed, but I need to leave room so that if my parts do not work, I can order more parts. I have also decided on doing a written part as well, by making a directions paper, as well as have a part explaining my vein finder on it. This will serve two purposes: say how to use my vein finder and what is actually causing it to work. Hopefully, the vein finder will work to use the parts. I will plan to make my directions sheet visually attractive, in order to be a good marketing vessel for my vein finder. I really need it to be a market vessel because the whole point of my project is not to just make a vein finder, but to make a better way for doctors to find their patient's veins, and if there is no way to communicate my option to doctors, then there is no use to make or advertise it. I understand the 3-D printing has taken a long time, but this week is when I will get most (or all) done. All in all, I am on track in finishing my vein finder.

This week, I am finishing up 3-D printing my vein finder because my model has three parts to it, that each need to be printed separately, and will be attached during the building process of the actual vein finder. As a result, I will simply need to have all of the parts 3-D printed, and have all of the parts installed and glued together during the actual construction of my vein finder. My parts to go in the vein finder are slowly coming in, however two of the parts are coming from China, so those may carry on until next week, but as of today, these parts (from China) have only been shipped (not delivered). I decided that I will not construct the vein finder in my home because my family lacks the equipment, such as a specific drill to put the parts together since the equipment must be tailored to my products. I have done some research, and I found places around Houston area dedicated to providing an environment to create products. These areas usually provide all the equipment I need. In fact, there is one of these areas in League City, called "Creatorspace". In this area, I can hopefully get some help (if I need it) since this area is full of knowledgeable, but also friendly, volunteers. On Google, this service got 4.9 stars from 9 reviews, so I can hopefully do my vein finder there. All in all, I just need to finish 3-D printing, which should be done by next week, and I can also (hopefully) get my parts delivered next week as well. As of today, I am on track on finishing my Genius Hour.

This week, I have done many things to begin the official construction of my vein finder! On Monday, my father ordered all of my materials, which I have decided from my research (on materials such as my light) and through designs released by other people. My father ordered the materials from Ebay, and they will come by May 1st. From this, the total cost was about $85, with all shipping and tax prices. The issue of this is that my vein finder must be cheap, and not cost $85. The price, however, is not representative of my final cost because in non-commercial projects, most website sell materials in bulk, rather than taking exact orders. As a result, my costs are way higher than normal, and these materials come in packs of 100. Therefore, my final price that I will call my vein finder will be the cost per item, rather than the cost for all of the items. The beauty of this is that I can still fulfill my goal of keeping my price low. Also, this week, I will go to the Clear Brook library and 3-D print my figure. My files are already uploaded to my computer, and to my knowledge the Clear Brook Library is open the whole week because STAAR testing is over, so I will go to the Library to print. Therefore, I can go and 3-D print this week. All in all, my products are coming alone fine, and I should be able to stick to my schedule that I previously made, in which I will begin assembly, hopefully, in May. In conclusion, I am on track on finishing my Genius Hour.

This week, unfortunately, I have fallen into a pothole, as far as doing my project goes. When I went to the Harris County Public Library (Freeman Branch), the staff stopped me from 3-D printing because I have to go to a session they do once every one or two weeks, and I have not attended them. The problem arises specifically from the fact that I have to wait even longer. My solution to this issue is to print at the Clear Brook library, but this week is STAAR Testing week and this forces the library to be closed. If the library is closed, I still would not be able to get my vein finder completed. Now, even though I have reached an issue, a good thing has still occurred. See, this week I took it upon myself to search for all of the equipment for the vein finder, and I have found all of my necessary materials and they are ready to be ordered. The even better part is that the seller of the parts sells them at cheap prices, and they sell them at a buy-as-you-need basis, in that they do not sell a twenty pack of nails, but they sell nails one-by-one. The beauty of this is that I do not have any extras. These parts are also professional quality and they are similar to many of the types sold in the real world. Therefore, my vein finder would be really close to the same product I would sell in the real world, adding on to the beauty and realistic nature of my prototype. In conclusion, I think I am still on track in finishing my vein finder because I have all materials necessary for the vein finder since all I need is to 3-D print and have my material shipped.

This week, I realized that I should review my vein finder before I print it, because I had a realization that my vein finder may not fit all of the requirements I set for myself. I changed my plan for the light of my vein finder last week, so this week I worked on the design, specifically the size and color of the light that I would order. I researched a little about the healthcare in Africa, and I realized that most hospitals in Africa are extremely small, and do not have a lot of storage for medical equipment. Therefore, I checked the size of my vein finder currently, and I saw it was about the size of vein finders in the market (115mm by 55mm by 21mm). As a result, my stress about the size is less. The color of the light of the vein finder also turned to be an issue for me since I learned that light and its color is one of the biggest factors of success in my vein finder. After researching constantly, I realized that the red that I originally planned to use is perfect because it can easily go through skin and make the veins show their location. All in all, unfortunately I had to postpone the 3-D printing of my vein finder because I did not want to accidentally print something that would not turn out accurate. However, I still think I am still on progress in finishing my genius hour because I am mostly done (if not completely done) with my research.

# data[].attributes.body
This week, I wanted to do research so I could fully understand the materials I should use for the vein finder. The most important material that I needed to research was the type of light am going to use. Although originally I thought a Ultraviolet (UV) Diode would be perfect, Infrared Light (of any kind) is actually better for two reasons. The first reason is that it can penetrate skin more easily, since the hemoglobin in the blood easily absorb the light, and allow the vein to easily be seen. The second reason is that infrared light has longer wavelengths than any other type of UV light. Since wavelength and energy have an indirect relationship, as wavelength goes higher, there is less energy. This less energy is actually better for the body. Therefore, I think I will most likely order infrared light, rather than a UV diode, since they have relatively the same price, therefore making the cost factor of my vein finder not change. This week, I also tried 3-D printing my vein finder, and I am trying to get an appointment at the Harris County Public Library to 3-D print next week (but as of today, Tuesday, March 27th, I still did not have the chance to go to the library, since I can only get an appointment by physically going to the library) , so by the second week of the April, I will order the materials, and assemble the whole vein finder by the end of April. Although the vein finder assembly may sound easy, it truly is the most difficult part of the project since the light in the vein finder can easily burn out if an issue occurs, or if the lights do not turn on at all. Another issue is if the 3-D printer does not print accurately. Although this chance is very slim, if this were to occur, my whole vein finder would not be able to work, because everything can fit in a certain amount of space, held by a specific depth. All in all, I am on track in finishing my genius hour.

This week, I took it upon myself to look for a way to establish ethos in my project because my ultimate goal with my genius hour is to spread the idea of a cost effective vein finder. If I do not establish myself as an individual who understands what they are doing, then no one will think my project will be worth their time. To do so, I found a study by N. Kurose, K. Shibano, T. Araki, and Y. Aoyagi, who stated that UV diodes are more effective since they are substrate-removal free, which is both better for the patient and the doctor. By finding out how effective UV diodes actually are, I can have the ability to prove that I understand both what UV diodes are, and why they are better than the current UV rays that are used in vein finders, that are found to give away cancer to either a patient or a doctor. However, by this, my ethos is established since I understand advanced biology, and medical terminology to help me explain my product like a professional. My number one goal that needs to be completed by next week is the actual 3-D printing of my vein finder. During spring break, I tried to review the skills necessary to make sure the 3-D print is accurate, so I did not actually 3-D print the vein finder. As long as I can 3-D print the actual vein finder, I am on track in finishing my genius hour.

This week, I had addressed one of my issues from Week 1. In Week 1, I was worried about being able to 3-D print the body of my actual vein finder, but after I looked around the internet, there are many places where I can 3-D print for an even cheaper price. For example, I found out that one UPS (United Parcel Service) store actually 3-D prints, in 15634 Wallisville Road, Houston, Texas. One more good thing I found out this week was that there was a study about gel manicure UV light lamps, and how the UV light emitted is not good. This study was done by the Skin Cancer Foundation, which also found that even UVA and UVB lights are harmful, regardless of their differences (Skin Cancer Foundation). By my conclusion, I can be more persuasive, in the sense that more people would be willing to use my vein finder since it does not contain anything that is harmful to the skin, which the Skin Cancer Foundation had found bad. My goal is to begin 3-D printing my vein finder during spring break, and to begin to place all of the lights and other things there. Due to my lack of engineering skills, I will need a lot of time to put all of the items in. I also need to order UV diodes from Amazon (the online shopping store). Besides those things, my Genius Hour project is moving along just fine.

# data[].attributes.body
This week, I learned a number of critical things towards my vein finder. Firstly, I learned that 3-D printing a vein finder is doable. In other words, there are released designs for a vein finder that I can 3-D print. However, my only question is how I am supposed to print the design? I understand that the Clear Brook Library and the Harris County Public Library offer options, but since this project requires many layers, it may be a little expensive. Also, based on my research on the internet, Amazon sells the U-V ray diodes (non-harmful type of U-V ray) in red, yellow, green, blue, and purple for about 5 dollars each. One problem that I feel I have hit is that, after I 3-D print my vein finder, I need to be able to assemble wires and the light in the vein finder, and I currently do not understand the given instructions with the design of the vein finder. Hopefully, I can find more clear instructions. In the worst case, I can simply use the bountiful instructions that are available for flashlights and other light-based devices, and use those methods, in this vein finder. Other than what I have mentioned, my project is going smoothly, and I am on-track on finishing. Next week, my goal is to find out more about the U-V Diode that I should use, specifically the color, since even the color can be the difference between success and failure in developing a vein finder.
