Gector and I have been working on a new project together, a heartbeat sensor. It uses a cool infrared LED with a receiver to bounce light off of the pulse in your finger (or wrist), and then send the received signal to an op-amp, which amplifies it and blinks an LED to your heartbeat.
Last time I shared about the engine, I had a few parts completed. Now that the semester is over, my engine is complete, and I had a wonderful turnout. :)
I have always been fascinated with the idea of electricity in the body, specifically neuron signals, whether it be the signals from the brain to the muscles, to the organs, or the communication between the different parts of the brain.
My first semester of college has been quite the adventure. I’ve met a group of great nerds, I’ve been having a great time with my classes, and midterms are in just a few days. I wanted to take some time to update on our engineering semester project: designing and building an oscillating air engine.
One thing that’s cool about the world of hamateur radio is that radio waves are all around us. You could be standing in the middle of a transmission going on, and not even know it!
Since I started using Linux 2-ish years ago, I have messed up the partitions on my laptop multiple times trying to fiddle with stuff. Through that, I very quickly learned the lesson of computer backups.
A few months ago, I presented the idea to Gector to set UTW (a friend group of ours) with ham radio. We put it on our list of projects to do, and left it on the back burner.
Today I ran lsb_release -a on my laptop and tower, and to my astonishment I was very behind on the upgrades.
