+    Playing the trumpet is one of my past times. In school, I play in the band and orchestra, and also in the Marching Band after school. So when my
+    trumpet instructor offered to give an old Cornet from the early 1900s (1909 is my estimate) for me to repair, I of course accepted. The cornet was in quite a state of neglect and disrepair
+    due to its age and the lack of mantaince. Many slides were stuck, one of the valves was immobile, much the silver plating was worn down to raw brass, and several of
+     the soldered connections were broken. So I set to work. I used a propane torch to repair the broken connections, and managed to use penetrating oil to free the valves.
+     I found a silver plating kit online, and used it to replace some of the worn-down plating. After about a month of on-and-off work, I managed to get a presentable cornet.
+  <br>   Heres the result:

+    After getting my license, I began searching around for some cars on Craigslist. However, I discovered that car insurance would probably cost more than the car itself, so
+    I started to look into other options. I discovered that motorcycles had much cheaper insurance, and cost less to buy. So I hopped on Craigslist, and found
+    an old 1982 Suzuki GN250, contacted the owner, and bought it for about $300. The Bike was in a state of disrepair, as it looked to have been exposed outside to the elements for a decade if not more.
+    The gas tank was leaking and rusted everywhere, the starter didnt work, and the turn signals failed to operate, in addition to numerous other problems.
+    But eventually, after a few days of work, I managed to get the engine running. Here's a video of the Bike's first start:

+   <br>
+   <br>
+   Next, I tried to figure out why the starter switch didnt work. I took the right handlebar assembly apart, and found some corroded switch contacts. After cleaning them,
+   the Bike started right up.
+   <br>
+   After that, I had to fix the turn signals. I made a simple oscillator circuit to test the blinkers, and connected it to the Bike. <br>

+    For my <a href="./xray.html" class="w3-bar-item w3-button">X-ray project</a>, I needed to make a Geiger Counter as a saftey component (A Geiger Counter is a device
+    that measures radiation, of which X-ray machines produce a lot of). So I searched around online
+    for a simple-"ish" geiger counter circuit. Eventually, I came across <a href="https://sites.google.com/site/diygeigercounter/" class="w3-bar-item w3-button">this website</a>.
+    The schematic diagram was open-source, and the parts were easily sourced, which could not be said about other designs I'd come across. So I went about making
+    the device. For the project, I decided to design my own circuit board, to practice my CAD skills. I used AutoDesk Eagle, because it had a free student version. After
+    a few days, I managed to design a board: <br>
+    <img src="./geigerboard.png"><img>
+    <br>
+    After designing it, I printed the board on glossy paper, and used an old clothing iron to transfer the ink onto a blank circuit board. After doing this, I dipped
+    the board in acid to finish the design. Once the board was finished, I soldered all the components in, and 3d Printed a case for the geiger counter.

+      One extracurricular activity I participated in during High school was Marching Band. A key part of Marching Band is the "The Field Show". Essentially, The Field Show involves
+      the band members performing a set of songs while simultaneously forming interesting formations and patterns. The Show usually involves a central theme
+      or idea, and through the Field Show, the band tries to convey a story to the audience. The Show was basically the main performance that the marching band worked towards,
+      and the component that took up much of our time and practice.
+      <br><br>
+      To make the show more interesting, I along with a team of friends built a set of remote controlled lights that added a "light show" element to the performance.
+      I was in charge of designing and fabricating the electronics and laying out the circuits, while the other team members programmed the patterns, and worked on other
+      aspects of the project. After about a week of work, we were finally able to use it in our performance at our first Marching Band competition. At the competition,
+      we were relieved to see that our creation worked and even recieved compliments from the judges! Through this project, I was able to practice my electronics and engineering schools
+      in a real world application.

+    To end my AP Physics 2 Class, a final project was required. So I searched around to find a suitable project. Eventually, I remembered reading about the early days of
+    radio, and recalled reading about how a simple glass tube filled with iron filings, called a coherer, functioned as rudementary radio recieiver. Normally,
+    the glass tube would act as an insulator, but When radio waves would
+    hit the tube, the iron filings would stick together--coher--and start to conduct electricity. By putting this device in a circuit, a Radio reciever could be made.
+    This type of recieiver was the type used to transmit the first signals across the atlantic ocean by Guglielmo Marconi. So with this plan in mind, I
+    set about making the vintage radio. In addition to presenting physics principles, I also wanted to practice my woodworking skills, so I tried to make the
+    wooden support structure as "artistic" as possible.
+    <br>
+    The transmitter is also relatively simple in design. The transmitter consists of a device that makes sparks of high voltage electricity. Because of this, the
+    transmitter could even be a barbeque lighter. However, the transmitter I built was slightly more complex than this.
