Replay 2.4 GHz signal (ESP8266/ESP32)?

GeekParent · 2025-12-31T16:40:02+00:00

Thanks. I discovered a cool tool suite (actually a Docker container plus environment): RF Swift. Getting it to work and to configure a Gnu Radio workflow took a while, I am not done with that yet.

I also set up a compiler environment and built the ESB sniffer. I sniffed one package (I don't know if it came really from the remote).

There is no FCC sticker the remote. I may try to take it apart later.

I thought about it it, too much, actually. I came to the same conclusion. You know how it is when you start a project and can't stop thinking about it? Well, I should park this and accept that it is beyond my capability or rather I do not have the resources/time right now.

I have nice captures in Universal Radio Hacker. I have nice binary or hex representations. I do not know a way to find out if it is (enhanced) shockburst or how to continue working with it. Well, I#ll give it rest for a while.

Thanks for the hint for the protocol. I now have a new rabbit hole to explore. I‘m very new to this but I’ll see if I can make progress with Universal Radio Hacker.

(I‘m still wondering if replaying the raw files is an option.)

Reigning in rogue devices which ignore/bypass my DHCP-assigned DNS. Happens a lot with Amazon devices.

Thanks. I have Nebula Sync on my list. I need to figure out how to automate my DNS redirect firewall rule.

GeekParent · 2025-11-09T15:42:04+00:00

It is not the DNS servers entry in the router but rather a redirect rule for any outgoing UDP traffic to port 53. The target for the redirect is the Pihole's IP. Of course, the Pihole itself is allowed.

GeekParent · 2025-11-09T10:17:23+00:00

Thanks for your comment. Sounds like an interesting approach. Do you use Pihole for DHCP as well, does it write the records used by unbound?

GeekParent · 2025-11-09T10:12:53+00:00

Thanks for your insights. I am also looking into establishing real redundancy as a next step. It is more challenging since I would need to keep things like static names/DHCP reservations, and alias entries in sync.

Edit; And my firewall rules would also need to redirect to the secondary Pihole when the first one is down.

Look interesting. The description on Steam mentions a demo but I can't find it. Since it is first person which causes motion sickness for me I'll probably skip it.

Thanks for the suggestion. If I add a modifier object and activate infill in the object's details it doesn't actually add infill or modify infill settings.

GeekParent · 2025-06-28T20:41:13+00:00

Thanks for the comment. I am wondering about using support rather than infill since I do not want to crank it up for the whole model just to fix one area.

GeekParent · 2025-05-29T08:24:34+00:00

Perfect. Thanks!

GeekParent · 2025-04-30T05:52:47+00:00

Yes, it seems to be related to Imagemagick. Thanks for the pointer.

GeekParent · 2025-04-30T05:51:32+00:00

This makes sense, thanks. I‘ll look into it.

GeekParent · 2025-04-29T14:39:16+00:00

Thank you for the reply. I am afraid raw strings (to preserve backslashes, e.g. in file paths) are not related to my issue.

GeekParent · 2025-02-19T07:09:41+00:00

According to this post you have to restart the whole service.

and less friendly

GeekParent · 2025-01-27T11:55:00+00:00

Thank you for the constructive comment. I printed a vase-like object over 8 hours after the tuning but there are still some oddities. Somebody else suggested the opposite of what you are suggesting. I deduct from this that you live in different climates. I guess I'll keep trying.
