Sentient Fridge

Tue, 23 Jul 2024 00:00:00 +0000

Wow AI got really popular. Anyways wouldnt it be funny if my fridge was sentient? I’m not sure what this says about my moral character, but I made the fridge very sassy and fatphobic towards you any time you try to open the fridge. It has a accelerometer and it uses that to tell if you’re trying to eat something. Then, it uses state of the art technology to vocalize its distaste against your consumptive attempts of self preservation.

Reflow Plate

Sat, 14 Oct 2023 00:00:00 +0000

This is a reflow plate i made out of a clothes iron. Typical reflow plates can be pretty expensive but i made this one for around 10 dollars.

Custom Nano

Tue, 02 May 2023 00:00:00 +0000

This was my first custom microctroller board. I thought it might end up being cheaper to buy a bunch of these really cheap PCBs and solder them myself than buying a bunch of arduino Nanos. In fact it ended up being a lot more finicky than i originally thought so it looks like making your own custom Nano doesn’t make too much sense.

Seismometer

One of my dad’s colleagues mentioned to me that it would be a cool idea to try to make a digital seismometer, and so thats what i did.

Thermocouple

Mon, 26 Dec 2022 00:00:00 +0000

When making my cloud chamber, i wanted to measure the very low base plate temperatures continuously. Why not make something to measure it? Unfortunately, thermistors are fairly nonlinear meaning they’re not so accurate, especially at low temperatures. Whats typcically used for the job is thermocouples, which use voodoo physics to measure precise temperature differentials. I plugged this into an arduino and shoved it into a small tin with an OLED, and it definitely did the job. The next big thing to do would have been to then tune it but that would require buying actual equipment :(

Electric Boat Inverter

Sun, 24 Apr 2022 00:00:00 +0000

This is the traction system for the AE boat. It uses a bunch of quickly switching FETs to drive the motor, and uses two relays to switch the direciton the boat is moving, pretty intuitive stuff!

RGB Clock

This was one of my favorite projects, cutting led strips to make it glow into specific number formations.

RGB! CLOCK!

Tesseract

Sat, 01 Jan 2022 00:00:00 +0000

Continuing on with my theme of making glowing objects, the tesseract was something that really caught my eye. I designed my own stand and 3D casing for the device, hoping to cut sheets of acrylic with a solar film to create a very low cost 2-way mirror. I ended up making a better one a year later as a gift with added structural rigidity. The whole thing is programmed with an arduino and plays various mesmerizing patterns.

This was a lightup display i made to teach kids how adenosine traveled in the signal transduction pathway.

Simon Game

Tue, 06 Oct 2020 00:00:00 +0000

I felt like it would be cool to make a game for some family friends’ kids who are really young. They ended up loving this game and actually really challenged themselves to get up really high. Unfortunately, there’s no flash memory to save the high scores, but you should believe me when i can say my score is in the high hundreds.

Quadraped

Mon, 13 Jan 2020 00:00:00 +0000

This spider robot was printed and then programmed by me. It uses these tiny stepper motors and was pretty flimsy. I eventually upgraded it to be remote controlled by adding a radio module to it. Then I connected it to my fleet of remote controllers including my gesture sensor, but also my drone controller.

Scrapped this together with a basic NRF transciever, arduino, and 18650 li-ion batteries.

Cardboard Robot Arm

Sat, 15 Jun 2019 00:00:00 +0000

This was one of my first projects which involved putting multiple functional parts together. This was super cool because it was the first time I made something that was different from the tutorials i saw online. All this one took was some tape, legos, servos, and cardboard.
