Endless Seltzer

I upgraded my seltzer machine by hooking it up to a 50lb CO2 tank, with the help of my friend Ian. We’re calling it “Endless Seltzer”. We both really love fizzy water.

We did some research online and found this adapter you can get that connects the SodaStream to a more industrial standard type tank. That’s all that’s really required for the minimum viable product, but naturally, we wanted to add a bit more engineering so we also built an internet-connected scale that keeps track of how much CO2 is left.

Although you don’t have to build the electronics part of this project to enjoy the fizzy benefits, you must understand the dangers of working with a pressurized tank of gas. If it falls over and the valve is damaged, the whole thing could become a dangerous projectile. Basically a missile. The main precaution we’re taking is to install a tank strap to the wall. Don’t skip this step. I’m also setting up a CO2 safety monitor/alarm just in case there’s a leak.

Webcam Privacy Friend – 3D Printed Eyeball

Meet my new webcam privacy friend, a motorized and 3D printed eyeball that sits atop my screen.

I’ve used stickers and post-its to cover my webcam for years, for peace of mind that my webcam is only accessible when I want. But it’s hard to remember to replace the sticker after each meeting, and I’ve been looking for an excuse to try building a simple robot companion.

Here’s how I made it.

Tape Measure Yagi Antenna

My take on this classic design uses pieces of standard tape measure steel as radials, a 1-inch diameter PVC pipe as the mast, and 3D printed couplers to link the radials to the mast.

Glowing Birthday Cake Embroidery for Estefannie

Here’s a birthday present I made for my friend and fellow YouTuber Estefannie. It’s an embroidery I designed with some of her favorite things, as well as some electronics to play sound and light up the birthday candles.

Last year Estefannie and I found out our birthdays are only a day apart, so naturally, we decided to do a youtube collab to celebrate and make each other gifts. I knew Estefannie moved into a house not too long ago, so I decided to make something to help decorate all that new wall space. Embroidery is a natural choice for me, but this time I used a computerized embroidery machine instead of doing it by hand.
