Nicely produced video but two things I think make it less great. 1) The sponsorship / advertisement is artificially linked to the content of the video and makes it more like an ad for the computer. It appears like the video is optimized for ad profitability but not necessarily for bringing most value to the DIY project. Sponsorship is fine, but I would prefer it to be separate from the video content. 2) There are some elementary electronic checks missing, eg the impedance of the speakers. If the ohms not match, the amplifier might actually get damaged.
