The other day, as a result of playing with gasoline, I got some second-degree burns. Eight years ago, in preparation for a backpacking trip to Sword Lake, my dad bought a 1-gallon can of Coleman Fuel (a petroleum distillate similar to gasoline but without the engine-performance-enhancing additives), to fuel his Coleman 442 pressure stove. After…

Introduction For no reason at all, I decided one day to make one of those top-lit updraft (TLUD) wood gasifier stoves that are a common design for DIY small biomass-fueled stove projects. The design has been researched pretty extensively and is viewed as a promising stove design to replace dirty and smoky biomass stoves commonly…

The concept of an oil lamp made out of a sardine tin is nothing new. The idea has been explored by others as a sort of survival lamp, which can be made with very simple materials. However, my design is different in that it’s meant to be used regularly and provide a brighter flame than…

Finding no other similar resources online, I created this printable list of the keyboard shortcuts in Ubuntu. There’s only one change from the default shortcuts: I’ve set Ctrl+Space to be the shortcut for playing/pausing media playback. If you like you can edit the provided .odt file. Here’s the infinitely low-tech way I got all these…

Introduction Where I live, the soil has a very high clay content, so I’ve tried a few times in the past to turn it into some usable clay-like material. Clay is easier to work with than metal and wood, can endure high temperatures unlike plastic, and is more durable. In my attempt to cast zinc,…

I created a tree map of Jane Lathrop Stanford Middle School for my Broadcast Media class in 8th grade, but it was never published. As I was doing research for that project, I stumbled upon the Canopy Tree Plotter, a tree map of Palo Alto, though since it didn’t list the trees at JLS, I…

Introduction I’ve been trying to refine my backyard soil into some workable clay in order to further my metal casting project. As you can imagine, this comes with some challenges as not all clay, even when purified, is suitable for making stuff. In the case of the clay in my area, it’s very sticky and…

Introduction Lately, when not crushed under the tedium of self-studying two AP exams, I’ve been trying to refine the clay soil from my backyard into clay. A post about that is coming. This post is about an interesting effect I noticed today as I test-fired pieces of clay. Basically, clays often contain iron oxides (compounds…

This one was held in San Mateo Public Library. First, I worked on a rice cooker whose non-rechargeable lithium battery had run out. From my understanding, the battery was used to avoid the need for an AC power supply, needed not only to keep the clock running when the appliance was unplugged, but also to…

This was my 2024 Synopsys science project. Abstract While liquid cooling presents itself as an efficient cooling method for ever-hotter integrated circuits, it is confined to mostly commercial applications and occasionally premium desktops. Instead, high-performance laptops rely on heavy and bulky heat pipes to bring heat from processor to radiator, somewhat defeating the purpose of…
