First sticking snow in Pittsburgh today!

Today I tested the third iteration of my DIY EMG sensor.

I am writing a rather complex Javascript project at the moment, and needed to include two different Javascript libraries.

I recently wrote a Teensy Data Acquisition GUI for recording data from a microcontroller/sensor onto the computer.

I finally got around to powering on those EMG circuits I made.

As part of my PPG project, I had to create a live-updating plot.

The PCBs came sometime last week, and I got the rest of my resistors and passives today.

I recently found out about histogram equalization.

Late last night I was greeted in my dreams by a green, ghastly spectre, who said unto me: "Instead of adding 1 image at a time, did you try stitching 2 and 2, then the two composites?

Howdy y'all!

I wasted like an hour and a half today trying to get this Playstation 3 camera working on my Mac: Let me tell you how I debugged it.

Hello!

Howdy!

I was reading about holograms and realized that I could emulate it on a computer.

I found this cool blog post that was trying to show Python's slower execution time does not just come from its interpreter, and instead was more interested in the benchmark that they ran converting ints to strings as a toy example.

This is Velostat: It's a conductive sheet that's sometimes used for packaging ESD-sensitive electronics, but is commonly used by wearables hobbyists since it changes resistance when anything happens to it.

I'm trying to record a stream of string data coming from a Teensy microcontroller over USB Serial.

Hello.

The problem with modern day tank armor is that it relies too heavily on brute strength for defense.

Hello!

Bear with me.

Before we start, I want to clarify that I am not just some neural network script kiddie, and that my blog is not going to be just a personal log of all the neural networks I make.

Any hard problem can be solved by randomly guessing — if you're good enough at guessing.
