K.I.S.S. Meshtastic QWERTY Messenger v2 for T-Lora, CardKB and Piezo Buzzer

by SomeGuy2023

Update: I'm publishing my second version. Much more refined and compact. Included is a full PDF for the assembly. ----------------------------------------------------------- I wanted to have a standalone Meshtastic device with a CardKB and Piezo Buzzer, so I don't have connect my phone. I can leave it plugged in on my desk and get alerted to new messages, as well as type quick replies. After looking around, many designs were very involved and I wanted to keep it super simple, hence I called it K.I.S.S. Meshtastic QWERTY Messenger. The entire setup is 3D printed without supports, except for the back/battery part. The BOM is also very simple: - ESP32 LoRa LILYGO T3 V1.6.1 Pax Counter [Amazon](https://amzn.to/3xKbW2r) - M5Stack CardKB (Card Keyboard) [M5stack](https://docs.m5stack.com/en/unit/cardkb) - Active or Passive Piezo Buzzer 12mm diameter [Amazon](https://amzn.to/49G3wX3) - Optional mini vibratory motor [Amazon](https://amzn.to/3W7Xmw2) - 2x Screws 3M x 28mm for hinges - 2x 2N2222 transistor (one for buzzer & one for vibrator) [Amazon](https://amzn.to/4aHzfIW) - 2x 1K Ohm Resistor (only one needed buzzer) - AAA Battery contacts [Amazon](https://amzn.to/3QakYfn) - 1x piece of heat shrink (electrical tape can be used as a replacement) - Several multi-color thin gauge wire (e.g. telephone line or CAT5) - Super Glue gel (for Keyboard) - Double sided tape (for Keyboard) I think that's it. I also included the screenshots of how to setup the node: External Notification Canned Messages To avoid any disappointments on using the Meshtastic there is currently no way to scroll through previous messages, so if you miss it you miss the message. However, there is an enhancement request for improving this. NOTE: There were many inspirations found across the internet, so I'm giving a shout out to those folks. I didn't opt to buy/build one of these, but if you don't like my design please consider one of these: Meshenger: https://www.printables.com/model/389311-meshenger-standalo
