Voltlog #271 – InTheMail (non-electronics)

Welcome to a new Voltlog, as the title says this will be a non-electronics mailbag, meaning I will show you what other stuff I am ordering and receiving by mail. A few days ago I created this poll on my youtube community page and asked where I should upload this kind of video, there were really two options, either upload to this channel or create a new one. I was kinda hoping for people to vote to upload them to the same channel because I don’t really want to manage a second channel and it’s also understandable if people vote for the same channel because they don’t need to perform other actions to subscribe to a second channel. And so it was decided to upload to the same channel but mark these videos as non-electronics mailbags.

Voltlog #254 – Epaper Display Pixel vs Segment Type

Welcome to a new voltlog, today we’ll have a little chat on epaper displays. You probably saw this post I made to my youtube community page a few days ago, it was about my epaper thermometer which suddenly showed the low battery sign and stopped working. I’ve only had this running for 1 month, when I received it, the battery was not connected so I thought it must have been an old battery or a bad one.

Voltlog #242 – InTheMail

Welcome to a new InTheMail, the series that will touch both your passion for electronics and your bank account at the same time. We’re gonna start with this kit of silicone hook-up wire, I was running out of thin silicone wire so I thought it would be a good idea to try one of these kits. The one I got is 26AWG, 6 different colors, each about 9m in length.
