Really neat project, see my sister comment (on analogue pagers still in service).<p>>I'd love to hear your thoughts on the IP-to-Phone-Number mapping logic (it's purely visual, but I'm really into it).<p>Personally, this seems like a really bad idea. The similarity to <i>actual phone numbers</i> might lead to confusion by non-technical <i>high-trust contactors</i>. Worse (e.g.) if the IP were 91.1x.x.x then this could lead to further confusion &/or erroneous 9-1-1 misdials (by inept contactors).<p>It's a UDP packet, ought it not be in IP-format?<p>>where you only want interruptions from a high-trust circle<p>I don't even have a phone contact number anymore. After you page me, I'll VoIP you back from an outbound-only.<p>But overall I LOVE that you have attempted this; only real problem for your average installer/recipient is that most home ISPs are firewalled (so a UDP7777 inbound isn't possible), but this <i>obviously</i> isn't for even your average technical installer.<p>----<p>Just leave me alone, world/SPAMmers!<p>How do you prevent malicious actors from invading your 7777UDPs?
>I found myself missing 1990s pagers.<p>I still use one which gets one-way service from <<a href="https://pagersdirect.net/" rel="nofollow">https://pagersdirect.net/</a>> (~$14/mo, with phone number and pager included). Most US cities, large and small, still have active infrastructure. I live in a city with a few hundred thousand people, great coverage.<p>This has replaced my mobile phone, which I no longer carry. It also prevents spammers from messaging... because the systems don't understand this antiquated technology [1].<p>For those interested, Pagers Direct has an email-to-pager option (I don't use it, phone digits only <i>please caller</i>, after the beep). It also has two-way pagers, which I have no experience with.<p>One caution: for one-way pagers, if you're out of range[0] when somebody sends you text, you will never get the message (no handshake/confirmation).<p>[0] does not use traditional cellular infrastructure<p>[1] TBH: most humans don't either, unless you explain how <i>to page</i> somebody: <i>key in your callback#/code</i> after the beep [no audio/text]<p>[•] I don't work for the above-linked paging service, <i>I'm just a very happy customer</i>.
Woah! The world really works in mysterious ways. I've found myself thinking in this space a lot recently. I've been working on a pager that takes the notifications from my phone and relays only the ones I want to see. I use LTE-M/NB-IOT to get connectivity anywhere and the device works and I'm looking to find a way to get a pcd/case made..<p>Landing page (doesn't link to anything): <a href="https://fob.launchbowl.com/" rel="nofollow">https://fob.launchbowl.com/</a><p>A little word dump of thoughts at the start of the journey: <a href="https://launchbowl.com/e_ink_pager" rel="nofollow">https://launchbowl.com/e_ink_pager</a><p>Your project seems really cool and allows you to bring your own hardware. Out of curiosity, have you blocked all notifications on your phone? Would this be run on your computer? Would you ever move in the direction of a physical device?
I'd love to get a real pager again too. But not LTE-M based because that's still a two way system so I can be traced.<p>I just have a pretty strong desire to get my anonymity back when I want it. Not because I need it but just to feel free again.
US: <<a href="http://www.pagersdirect.net" rel="nofollow">http://www.pagersdirect.net</a>><p>I have and use one, partially for the reasons you list above.<p>[•] Not a representative of the company, just <i>a very happy customer</i>.
Yes! I really want a physical device for things like this. It's cool we are both thinking about it: <i>independent invention.</i> That is a sick website. Love the design!

I will send my thoughts but at which number?
Do you have this running on some kind of pager shaped device? What do you use it for?
Really cool. I like the flashing red.
What is "UDP-7777"? Is it some kind of software? What does it do exactly?
Is the source available? What is presented is a machine-generated website with very little meaningful information and mystery binaries for three platforms.<p>PS: The "SHA256 CHECKSUMS VERIFIED." is static. No hash check is performed, and as far as I can see the website doesn't have a list of hashes to check.
I normally work on larger projects (BrowserBox, dn), and now believe in new release methods which is why the source is closed.<p>Your radar was okay: site is machine-generated by build workflow which pushes the binaries. The "Verified" label reflects internal CI attestation, but without public hashes? Might cause concern. Did not consider, tho based on your comment I've now replaced with "Digitally Signed and Notarized".<p>So reflects more accurately how the binaries are always digitally signed and notarized (Apple Developer ID + Microsoft Authenticode) with our company certs. SOP for my releases. The verification is the cryptographic signature checked by your OS kernel, not just a text file.<p>I actually like this presentation better now!
Thanks for this caution / opsec.<p>----<p>Public WhoIS registrant:<p>Chris [redacted]<p>The Dosyago Corporation<p>Beaverton, Oregon<p>----<p>OP has ~2 year old /hn/ account, with ~11k karma<p>----<p>I have made no further investigations, but obviously haven't installed this myself (as I have an IRL pager that solves similar issues to OP's).
