I had missed this post…welcome to Scanlines @pinigrigio and thank you for sharing these schematic, great first contribution!
FYI I just edited it as the link to the PDF file wasn’t working (I blame gremlins).
Also maybe we will later move the PDF into the #wiki (which will gradually move to https://wiki.scanlines.xyz). At the page Video DIY schematics we already have two Archer devices but @pinigrigio’s one is different.
