  • GitHub repo Marlin

    Marlin is an optimized firmware for RepRap 3D printers based on the Arduino platform. | Many commercial 3D printers come with Marlin installed. Check with your vendor if you need source code for your specific machine.

    Project mention: Just bought an Ender 5 Pro. What else should I buy? | reddit.com/r/ender5 | 2021-02-23

    Good news on a heated chamber, Marlin's getting patched with native PID control for chamber heat because I couldn't get this fancy printed stand alone electronics case I was trying to print to stop warping on me. So you won't need any extra arduinos for it, just make sure you've got a spare pin for heater control on whatever printer board you run, and use a Fotek SSR-10DA or the like to control power to your heater/heat-gun.

    Project mention: ESP32 BLE Secure Server for multi-clients (with PassKey) | reddit.com/r/esp32 | 2021-02-19

    This project is about a BLE secure server that supports multi-client through the static passkey. A system where ESP32 becomes a BLE server, iOS and Android become a client, and receive data from the server if they have a correct pin code. Also, the operation of BLE in iOS and Android is different, so we need to pay attention when implementing it. Video: Here / Code: Here

  • GitHub repo ESP32Marauder

    Project mention: is it possible to use a one-button-bluetooth-camera-trigger with an ESP32?? | reddit.com/r/esp32 | 2021-02-06

    Maybe. Depends on whether the data between the Bluetooth pairs are encrypted. You could checkout some ESP32 Bluetooth sniffer examples, this may help you identify the camera trigger within the data stream. This may help https://github.com/justcallmekoko/ESP32Marauder let me know if you crack it :)
