AirTalk: A Wireless LocalTalk Project

(1/2) > >>

cheesestraws:
Thought people might be interested in this project I've been working on - it's perhaps strictly speaking more a Mac thing but it's Lisa-relevant too, or at least I've got one plugged into my Lisa and it works, so it's at least Lisa-adjacent.

This is AirTalk: it's a wireless LocalTalk dongle.  All the AirTalks on the same WiFi network can see each other, and they all are on a sort of virtual LocalTalk bus network tunnelled over UDP.  All the computers or other devices attached to any of the AirTalks (and this can be a whole LocalTalk segment!) can see the devices on all the other AirTalks as if they were on a continuous LocalTalk network, though with added latency and thus reduced bandwidth.  No drivers are necessary.  I'm quite pleased with it.

If anyone's interested in this or how it works I'll answer questions or talk about it probably ad nauseam, given half a chance, but I'm trying to avoid being too tiresome.

But I do want to say upfront that it's absolutely dependent on TashTalk, Tashtari's brand new LocalTalk transceiver based on a PIC.  That little PIC has opened up all kinds of fun stuff for the future...

Yes, sorry - I was trying to avoid sounding too self-promotey, but I fear I ended up obscure instead.

I'll add that the firmware is here, and the hardware designs will also be here once I've got over my anxiety about choosing a license.  https://github.com/cheesestraws/airtalk

Yeah, I've been following the discussions on 68kmla. This is really close to something I've been contemplating for the past few weeks. What I want is an all-in-one package that does this:
- plugs into a printer or modem serial port
- has at least on-board PPP, and perhaps also NTP daemon, recursive DNS resolver, and maybe some TLS tunnel such as an HTTP server that supports forward proxying HTTPS and/or FTP requests
- on the other end has either an Ethernet port or a Wi-Fi interface
- will route (forward) traffic from the serial PPP interface to the Ethernet or Wi-Fi interface
- zero-conf / plug 'n play

rayarachelian:
No promising anything, but supposed I wanted to add support for this to LisaEm, how would I go about it?
Is there some library I can call and pass bytes to/from Serial B for AirTalk that works over UDP on various OS's?
