ESP32-C3 Adblock

pinhole is great but if the device fails your network is down. I swapped to nextdns because of that. maybe support of multiple devices would fix it - now that is this cheap it would not matter .

If you're ever thinking about getting an ESP32-C3, do yourself a favor and get the variant that you can connect an external antenna to. The normal C3 has a built-in antenna that is extremely weak, making it useless for most things I was planning using it for.

Please just write the first sentence of your README yourself

Weird how the readme talks about hash collisions, but not in the way I would expect. Two blocked domains with the same hash isn't a problem, they both need to be blocked.

Where hash collisions matter is false positives, e.g. if hash(google.com) = hash(adserver.com). There does appear to be a web dashboard and /unblock api so should be straightforward to resolve.

I think it could fit even more domains using a Bloom Filter or similar probabilistic data structure. With a chance of false-positives of course. But that's a trade-off the project already makes.

I'm a bit of a paranoid freak that likes lists, so I've got a PiHole that has a total list of 14-16M blocked domains.

Great idea, and good for casual blocking, but I'm almost moving to an "allow list" mindset. This solution would probably work better for that, I wonder if the good parts of the internet would fit into an 140k list.

Whitelist/allowlist is easier, e.g., it's smaller

Depends on the user but not everyone is visiting new websites everyday

Even for those that are, the number of domain-IP mappings needed will be relatively small

Definitely under 140,000

Most DNS data I use is "static", it rarely changes. As such most times I don't have to make DNS queries. I store the domain-IP mappings in proxy memory; this is faster than DNS

No "blocklist" needed

There's no point in using PlatformIO for ESP32 MCUs. The native ESP-IDF extension works much better.

I would only recommend using it instead of the standard Arduino Processing IDE.

10ms? Good grief that’s slow.

Cool idea, latency might be too high, wish the docs weren't all AI vomit.

"They were too preoccupied with whether they could, they never stopped to think whether they should"

Jokes aside, very impressive that it works!

i dont get pihole. just use a proper dns? if you want local, just use unbound?

Wow, this is an atrocious name for a project haha. Cool though.
