In this episode, we talk about operational amplifiers (opamps) and the 4000 series IC that Øyvind has been writing a series of posts on. We also accidentally came across a funny error on Arrow’s website 😅.

I started this blog in 2012 with the idea of being able to do what I love (electronics) while traveling.
Since then, I've traveled and lived all over the world. I've been to Mexico, Colombia, the US, Australia, China, Fiji, Germany, Singapore ++. And you can read about (or see videos) of these experiences here.
In this section, you can find articles related to my travels and the lifestyle of being a maker.

In this episode, we repair an old Sanyo amplifier. In this episode, we find an old amplifier in the trash and we try to repair it. Will we able to? Listen and find out. Listen to the Podcast Show Notes
Cap Half Full #5 – Let’s build a buck converter!
In this episode, we start out with the idea of building a buck converter with a microcontroller. We realize that we’ve never built a buck converter before, so we go through our thought process live to figure out what we need to do. We built one buck converter each. Elias used a Bluepill and Oyvind […]
Cap Half Full #4 – Custom NAS, nRF52832 DFU, and electronics we should know
We talk about a custom NAS build that hooks up a screen and buttons to an Odroid, Øyvind has been developing for nRF52-something and finally we discuss some basic electronic stuff that we ought to know.
Cap Half Full #3 – Arduino Polenta, scopes, and HDMI
We talk about the new Arduino Polenta and how DisplayPort over USB C might be implemented. We also talk about the $42 Etepon scope vs the $3500 Siglent SDS5034x scope.
