Too few sampled comments (8) to say how often HN recommends it.?
Why HN links it
HN readers link danman's blog as the original reverse-engineering research on cheap Lenkeng HDMI-over-IP extenders, covering stream capture, HDCP stripping, and HDMI EDID emulation. Commenters cite it for those devices.
Summarised by Claude from a sample of 8 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.

HN discussionYou don't even need go get the chips, devices like this strip the HDCP and turn the stream into MJPEG. http://blog.danman.eu/reverse-engineering-lenkeng-hdmi-over-... Here is their 4K device, don't know if it works like the HD device, but it would seem there is a fair chance it does. http://www.lenkeng.net/Index/detail/id/147 You can buy these devices on eBay.

HN discussionWhen using this awesome piece of software, you probably want to give a miss to the "blue pill" board recommended in the README file, and go instead with ST-Link v.2 clone, which has identical hardware and pricetag, while being considerably more portable: https://blog.danman.eu/2-usb-crypto-token-for-use-with-gpg-a...

on “Daniel Kucera: "[PATCH] mmc: core: allow detection of locked cards" -- CMD42”There was some effort to reverse engineer those devices [1] so that one could use for example either transmitters or receivers paired with normal PCs and not just connecting them straight each other. There are also newer models around, though I'm not aware of any reverse engineering efforts so far. If you want to tinker with them, please leave some writeup of the results. Beware that there are both HDMI over IP and…
