From 2017-2020, I went through 9 prototypes before arriving at a design
and working prototype that I was satisfied with. Version 9 is a
resonant solid state tesla coil) driver. It is inspired by Loneoceans's SSTC
driver and Steve Ward's DRSSTC Guide. However, the problem
with my driver is that it blows very easily as there is no tuneable inductor in my ZCS (if these
are strange words to you, check out Loneocean's blog).
I have soldered together the UD2.7 driver, but have yet to test it due to missing parts.
I also want to work
own musical interrupter. Probably with multiple channels like Franzoli
Electronics (I also want a youtube channel that plays tesla coil music man!!)
After that, I want to try building a QCW tesla coil, which is kind of considered the pinnacle of
solid state tesla coils as it is pretty advanced and can achieve arc lengths up to 10x its size!
(DRSSTC's can only do around 2x)
Gao Guangyuan is a big inspiration to me as he is from the same country and high school as me,
just that he is a generation older :) His tesla coil is at Singapore's science center, and he is
probably the best tesla coiler to have existed in Singapore. If you're reading this Loneoceans,
thanks for paving the way and thank you for your help via email as well! If anyone else needs
tesla coil design help, I'd be happy to lend a hand to a fellow hobbyist.
Geth is an open
source ethereum client written in Go,
and is one of the popular options for setting up an Eth node. I want to dig into the code and
understand this mindmap.
I read about Merkel Patricia Trees (MPT) in Ethereum when trying to learn the differences
between fast and full sync in Geth (Go Ethereum Client). I heard that the Verkle Tree is much more
superior, but I have yet to understand the technical details. I'd be happy to be enlightened by anyone who understands it.
I have explained
Uniswap V1 and am in the midst of
working on a video on V2. Apparently V3 has math that is used in SpaceX's vertical rocket
landing (btw I am also a hugeee fan of starship
updates on youtube) so I am quite curious what that really means.
In 2016, I studied UCB EdX course
on quantum computing (QC), and wrote a report
on it in 2018 on Grover's and quantum teleportation. At time of writing (2023), one of my research interest is in quantum information (QI)
e.g. Petz recovery channel
After that, I started studying Schrodinger's equation in 2018 for a physics assignment where we
had to write about any physics topic. That's when I fell in love with Quantum Field Theory (QFT) and
abstract math (manifolds, topology, differential forms, etc). I aspire to do string math one day,
but it's going to be quite a while before I get there. I make some videos on my youtube channel on
topics like spin
, lie groups
, or my research project
(hopefully publishing on arxiv soon).
Recently, my focus has been on conformal field theory (CFT) and quantum information (QI), topics
which I still know little about. I post technical content on my blog
I was inspired to create
from my attempts to self-study quantum field theory.
Having an inkling towards high
, I certainly am interested
in all the high voltage equipment (ion sputtering, semiconductor manufacturing). At my mentor's A*
lab, there was a secondary ion mass spectrometer (SIMS) that was eye candy whenever I walked past
Anyway, my dream is to be a lab tech at CQT (also aligns to my quantum computing interest), or any
lab that has vacuum equipment. I want to play with liquid helium cooling if possible too.
If I am rich enough, I want to have a lab like Sam
. For now though, I am trying to replicate his heterodyne interferometer
, but am still lacking a HeNe
For those interested, an absolutely amazing resource is samlaser
I've installed Linux
From Scratch (LFS)
, which is pretty much just a bunch of "configure, make, make install". I daily drive Arch
on my Intel macbook, btw ;)
I hope to contribute to the linux kernel one day and
write my own kernel module extensions.
I've managed to join the linux kernel mailing list, and am going to submit my first patch soon. My
explorations can be
So far I've just poked
around with xv6
Some resources that seem pretty good to me: channel
I am not good at CTFs, but I have filed a CVE
for crashing my
router with nmap LOL. I know the bare basics of buffer overflows, exploits, and metasploit, but have
not had much experience breaking into actual systems (I do intend to do OSCP in 2024 though hehe).
As I am passionate about low level stuff, I intend to focus on binary exploitation.
I studied a bit of Andrew Ng's ML course
in 2016 (was quite proud to learn that he was an alumni from my high school too hehe). In
2018, I did a school project on Optical Character Recognition (OCR) for handwritten math symbols.
The original goal was to recognise entire equations, but that proved to be too big a feat for me
(but not for MathPix
Big fan btw @ MathPix team).
HAM Radio (9V1BL)
I am interested in antenna design and APRS (communicating with satellites). I own a Kenwood TM-V71A
M4 (good because it has a data port that allows programming! which I will embark on soon) and a
HackRF One. I intend to go into radio engineering, i.e. transmission lines, impedance matching, but
pretty expensive :(.
The Thought Emporium's video
is a project
I am hoping to achieve with my HackRF One SDR too.
I am very very very very interested in modular robotics. It seems like research projects like superbot
do not have much updates, which
makes me sad :(. After time clears up, I will develop an open source modular robotics
If scaled up in quantity and scaled down in size, I think the applications are quite endless
especially in cubesats and space exploration.
I am also interested in MIT Cheetah
, as they are high-torque, fast, precise, and have sensors to allow for closed loop
control. I wish to purchase some to built a robotic arm (like Skyentific
) and an MIT cheetah replica
(for tertiary institutions?).
Lastly, I am strongly pushing for the development of Open Source Electropermanent Magnets (EPM)
So far, Ara Knaian
has used them in his modular
robotics thesis, and OpenGrab
is an open
EPM. My dream/hope/goal
is to bring down the cost
and therefore increase EPM's popularity in the hobby/robotics electronics community.
I want to bring EPMs to market in the long run. I also have some other ideas (if you are keen you
may contact me to discuss). But for now, I don't have much money so I am just giving coding and
