ReflectionsOS reviews and mentions

• Arduino and BLE on ESP32 as server and client combined, using NimBLE
  3 projects | /r/arduino | 25 Jul 2023

  Below is the source code I wrote. It is part of the code I wrote for https://github.com/frankcohen/ReflectionsOS and does not compile by itself - I include it as an example to write your own code. I am distributing it under a GPL v3 license - free software, when you change the code you need to publish your code to the world. I use the code in my Reflection's open source project at https://github.com/frankcohen/ReflectionsOS in the BLE.h and BLE.cpp code files.

• ESP32 USB is frustrating, try JCUSB for S3 + USB + CDC + OpenOCD + Arduino IDE
  3 projects | /r/esp32 | 4 Jun 2023

  I am using JCUSB in my upcoming open source project Reflections, a portable and mobile way to make animation experiences possible. Check https://github.com/frankcohen/ReflectionsOS for source code, examples, experiments, and details.

  other documents are there, for example using ESP32 and SD/NAND as MSC, using JSON data, and other sketches are at https://github.com/frankcohen/ReflectionsOS/tree/main/Docs

• ESP32-S3 USB frustrates me, you too?
  3 projects | /r/esp32 | 21 May 2023

  I'm building an ESP32-based wrist watch to show movies of my kids. It's an open-source platform (https://github.com/frankcohen/ReflectionsOS). I'm using the built-in USB support in ESP32-S3 and building code using Arduino IDE 2.1.0. I haven't written my own board definition yet, so I'm using the Adafruit Feather ESP32-S3 No PSRAM board. Most of the time I have to go through these steps to get the board to accept a new code upload:

  Thanks! My hope is my project becomes a useful open-source resource for other makers too. I want to get the USB upload working to the same degree as the reference dev boards. That's why I'm working on this now. The repository is at https://github.com/frankcohen/ReflectionsOS

• Anyone know of an accelerometer gesture sense that doesn't require tensorflow or other remote AI?
  2 projects | /r/esp32 | 20 May 2023

  I'm working on my wrist watch project (https://github.com/frankcohen/ReflectionsOS). It has an ESP32-S3, accelerometer, compass, and GPS, no touch screen, no buttons. It's all open-source. I am searching for code to interpret accelerometer data for gestures. Like making a big circle would register as a gesture, or shaking left and right a few inches would register as a gesture. I can't depend on Wifi/Bluetooth networking to a backend service while this is in operation. I could use a Tensor flow or other approach for training while networking is available. What have you seen? Pointers please. Thanks! -Frank

  Thanks! I'm glad to hear your experience with TFLM and the others. I found the Dynamic Time Warping algorithm to train and find patterns. I got it working today on ESP32-S3 and an LIS3DHTR accelerometer. It's accurate about 70% of the time. I'll publish the source to the Reflection's Experiments repository https://github.com/frankcohen/ReflectionsOS/tree/main/Experiments soon.

• AirGuitar fun with ESP32, Bluetooth Classic A2DP, SD NAND, Accelerometer

• [PCB Review] An IOT playground board based on esp32 s3 wroom

  I agree, there's nothing like making your own board. My open-source open-hardware ESP32 project is here: https://github.com/frankcohen/ReflectionsOS. It's a round 34 mm double sided board for a wrist watch project. Hoping to do what you did next week, post the schematics for feedback and quality improvements. Thanks for the inspiration. -Frank

• ESB32-S3 + NAND SD Storage + USB MSC = Arduino that shows up like a disk drive
