+<p>Took me a few weeks but I finally chewed my way through it. Thoroughly enjoyable pulp sci-fi. It has been fun to read this whilst also playing Cyberpunk 2077 and think about how the two might cross over.</p><p>(comment on <a href="https://bookwyrm.social/book/1437488"><i>Judge Dredd Year Three (Judge Dredd: The Early Years)</i></a>)</p>

 I recently purchased a [Heltec v3 Radio](https://heltec.org/project/wifi-lora-32-v3/) after being inspired by [Jan Wildeboer](https://social.wildeboer.net/@jwildeboer/113191557900339340) and in turn [Andy Kirby](https://www.youtube.com/watch?v=yt6NOm0Gdy8) to try out [meshtastic](https://meshtastic.org/), a LoRa mesh network that facilitates off-grid messaging over a mesh network. I purchased my radio from AliExpress and it took a couple of weeks to get here but it arrived this morning.
 
 The first thing you need to do in order to connect it to the meshtastic network is flash the firmware onto the device. Meshtastic provide [a very fancy web-based firmware flashing tool](https://flasher.meshtastic.org/) which uses standard browser APIS in Chromium to talk to your device over USB serial port in order to write the new firmware. The [provided documentation](https://meshtastic.org/docs/getting-started/) is very good and provides links to USB drivers for windows and mac. As it happens, drivers for linux are typically already installed in modern distributions like Ubuntu but there may be a little bit of extra work involved in setting things up so that your machine can use them.
