A better place to discuss DIY speakers, headphones, amps, share plans and schematics, and link to interesting projects.
Instances of crazy fixes that actually ended up working. Or not working, I'm a description, not the cops.

A subreddit for practical questions about component-level electronic circuits: design, repair, component buying, test gear and tools.
Welcome to /WLED! This is a community mainly for WLED users to ask questions, show off their work, or help new users out!
There are many elements that make an frc game unique, personally, I think shooting games are more entertaining, the game should be very heavily based on strategy and have an endgame that is worth points besides just RP (basically crescendo but with useful endgame). What do you guys think?

ESP32 is a series of low cost, low power system on a chip microcontrollers with integrated Wi-Fi and dual-mode Bluetooth. The ESP32 series employs either a Tensilica Xtensa LX6, Xtensa LX7 or a RiscV processor, and both dual-core and single-core variations are available. It includes in-built antenna switches, RF balun, power amplifier, low-noise receive amplifier, filters, and power management modules as well.
I wanted to share this esp32 project that classifies numbers from the camera with TensorFlow and streams the result over MJPEG.
It is far from perfect. Particularly it works best on numbers on a white background since manual processing converts the camera images to look like mnist dataset images before running them through the tensorflow model.
Here's the performance of the included model:
-
TensorFlow micro example implementations of layers: 1390 milliseconds
-
ESP_NN (ansi c implementations): 217 milliseconds
-
ESP_NN (ESP32S3 specific implementations): 21 milliseconds
The model used in this project has the following structure:
-
Input Layer: 28*28
-
Reshape Layer: 28,28,1
-
Conv2D Layer: 32, kernel size=(3, 3), activation="relu"
-
MaxPooling2D Layer: pool size=(2, 2)
-
Conv2D Layer: 64, kernel size=(3, 3), activation="relu"
-
MaxPooling2D Layer: pool size=(2, 2)
-
Flatten Layer
-
Dropout Layer: 0.5
-
Dense Layer: 10, activation="softmax"

This subreddit has been taken private from June12 in support of the strike on reddit to protest the upcoming changes to the pricing structure for the reddit API and related rule changes. ------- You probably want all your electronics to run on the 18650 lithium-ion cell. You just don't know it yet.
