Microwave Gun! If you’re already building laser rifles, why not build low frequency stuff too!

Mini Telsa Coil

Mon, 29 Jul 2024 00:00:00 +0000

Coils are super fun! I wanted to show other people the coolness of tesla coil power transfer. Besides, my large desktop tesla coils are a bit big, why not make one super small? This one uses the very popular slayer exciter circuit topology which requires very few components and does not rely on very precise tuning. The result is a pretty cute high voltage tesla coil that can still wireless transfer power but remains relatively safe.

I made this with my friend jaeden. It uses some pumps to spin the water and lights it up from the bottom :0

Scanning Quantum Tunneling Microscope

Sat, 13 Jul 2024 00:00:00 +0000

This is a scanning tunneling microscope i made! If it looks janky, thats because it absolutely is. In fact, most times in the day, the thermal expansion of the device causes the SNR to be extremely low causing the device to be unusable. But for a couple hours of the day (for me around 4PM), the temperature peaks and theres a brief 20 minute window for some mesmerizing photos to be made.

Fluid Visualizer

Here’s a laser experiment i always wanted to try! You can get a lense that is designed to reflect a ccollimated laser beam into a line of light. This is nifty because you can then use it to light up a plane of gasses. This is a cross section of moving water vapor.

Plasma Orb

This is my first iteration of a SiC Inverter. It gets its own page because this version was a much less serious attempt at a working product. But it at least spun a motor!

Plasma Ring

Xenon gas has the really nice ability to be very thick and viscous, and as a result, create these pretty stable plasma rings which soak up power from high frequency magnetic fields.

Solid State Tesla Coil

Sat, 25 May 2024 00:00:00 +0000

How about a singing tesla coil? I designed this tesla coil to use an antenna to feedback oscillations so it can tune itself. Because of all the parasitics of tesla coils, having it self tune is pretty common. Im then using a 555 timer to modulate the signal so that the output power can be adjusted. Because of this modulation technique, the plasma patterns are super unique!

Laser Gun

Tue, 02 Apr 2024 00:00:00 +0000

Laser guns are not strictly legal but as long as im not selling it or using it, i should be fine. This laser is found in high power projectors and has been given a new life as this cool laser gun. The laser gets quite hot so its recommended to have a pretty beefy cooling solution on it.

Laser Pointer

Wed, 31 Jan 2024 00:00:00 +0000

This is the first laser experiment i made. This one is already powerful enough to blind you if you touch it!

Optical Spectrometer

Mon, 03 Jul 2023 00:00:00 +0000

This thing is so cool. I bought a diffraction grating and thought about how cool it would be if I could make something to decode the signals. I have it fed into a raspberry pi with a screen, that calibrates from LEDs and then uses that to find peaks at different optical frequencies. This is then used to find an element in its database to figure out what exactly is producing that light. Then, I used one of my many plasma generators to test how well it works.

Flyback Generator

Wed, 28 Dec 2022 00:00:00 +0000

This flyback generator is a super simple self stable high voltage oscillator. It’s switching a transformer near resonance and getting insanely high power out of it.

Jacobs Ladder

Spark gap tesla coil are definitely one of the scariest you can make. Not only are they super illegal, but they’re also very dangerous and violent. I made 3, and they’re soooooo cool. They also absolutely rust the heck out of the spark gaps on account of the excessive amounts of ozone generation. I have them powered from various size flyback generators. Since its a pulsed power source, the resonance calculations are not as important meaning its not too difficult to scrap one together without a ton of analysis.

Reality Breaker

Sun, 03 Jul 2022 00:00:00 +0000

This uses radioactive decay to trigger a geiger muller tube, which converts the timing of this to a a random number. This is a truly random number since radioactive decay is inherently nondeterministic which means it breaks the laws of classical physics.

Un-Toaster

Sun, 28 Nov 2021 00:00:00 +0000

I got the inspiration for this project from Joel Creates. It was too funny of an idea to not try out, and i was looking for things to do with my atomizer! My family doesnt really eat toast so i went to friends house to try it out, and it kind of works…? It just tastes like toast that you’ve left out, sort of like slightly soggier bread ends. Highly recommend, definitely a 10/10 decision. Added RGB lighting for extra FPS.

Flyback Generator

This flyback generator was used to create super high voltages for some other interesting projects like the plasma vortex.

Your body has lots of capacitance! The idea of this theremin is that a bistable oscillator can use your capacitance to affect the frequency of a note, pretty cool!
