In a video by @Techconnectify@mas.to, Alec goes into a deep dive into the simplicity of his particular model, its shortcomings and variety of data logging tests in an attempt to fix them.
TL,DW: Very simple, cheap and ingenious design, with one compressor loop between the fridge and freezer in series. However, its temperature sensor is wonky and so the fridge is more affected by how long the compressor operates than the actual temperature itself. There is a signficant temperature differential between the top and bottom, fans on the exterior or interior could help but with the faulty sensor only made matters worse. With the controller replaced with a proper temp control unit the fridge functioned much better.
Typical response from new visitors to his channel: “Why would I be interested in that?” followed by “Stayed for the whole fascinating video.”
He has some serious skill when it comes to making absolutely anything interesting. 3 years ago I had no idea what a CED was, but after watching his 2 hour long 5-part documentary on this failed media format and its history, I now have a small collection of them.
