Cba Podcast

You thought that we finally learned from our mistakes and abandoned this podcast, and you thought wrong. Once again it's time to lower your standards, and enjoy a new episode of the CBA Podcast. We start with some PCB failures and flaws, followed by a very brief review of the Hackalot lasercutter & vinylcutter workshop. We attended T-DOSE, which is a Dutch open source event hosted in Eindhoven.  Then for something slightly out of the ordinary, we talk about back-of-envelope calculations about whether a climbing-rope can actually break if I fall. (Spoiler alert: it cannot.) Some clarifications and errata about this climbing-rope segment: To calculate maximum force on the rope, I used the harmonic oscillator formula given here , where the actual force is calculated from fall factor, mass of object, but also the rope's rated impact force. (I forgot to mention that). Also, I made an error: I mentioned a maximum actual force of approximately 85% the rope's rated impact force, but this is in fact less than 70%
