FOMO (Faster Objects, More Objects) enables real-time object detection on low-end embedded systems
FOMO used to stand for “Fear Of Missing Out” in my corner of the Internet, but Edge Impulse’s FOMO is completely different, as the “Faster Object, More Objects” model is designed to lower the footprint and improve the performance of object detection on resource-constrained embedded systems. The company says FOMO is 30x faster than MobileNet SSD and works on systems with less than 200K of RAM available. Edge Impulse explains the FOMO model provides a variant between basic image classification (e.g. is there a face in the image?) and more complex object detection (how many faces are in the image, if any, and where and what size are they?). That’s basically a simplified version of object detection where we’ll know the position of the objects in the image, but not their sizes. So instead of seeing the usual bounding box while the model is running, the face position will be […]
Getting started with Maker Nano RP2040 using CircuitPython: Blinky, RGB LED, and Piezo Buzzer
CNXSoft: This getting started guide was initially posted in Thai language by Suthinee Kerdkaew, and I’ve just translated her work into English with some minor edits. As discussed in an earlier article, Maker Nano RP2040 is a board following the Arduino Nano form factor, but with a more powerful Raspberry Pi RP2040 microcontroller. The board also comes with plenty of LEDs, as well as two RGB LEDs, and a piezo buzzer for audio output. Mr. Jean-Luc Aufranc has just given me a Maker Nano RP2040 board received from Cytron for review. I’ve never used a board before, so it’s my first experience, and in this article, I’ll try to program Maker Nano RP2040 with CircuitPython with three demos: a blinky sample, changing the color of the RGB LEDs, and playing a melody through the piezo buzzer. Let’s see if I can do it. Let’s get started. I first downloaded the […]

SmartKnob View is a DIY haptic input knob with WiFi and Bluetooth connectivity
Soon after writing about RoenDi rotary encoder with a built-in color display, readers pointed me to SmartKnob View, a similar-looking project but featuring an ESP32 module for WiFi and Bluetooth connectivity, plus software-configurable end-stops and virtual detents. The latter is enabled through a brushless gimbal motor paired with a magnetic encoder to provide closed-loop torque feedback control. Just like RoenDi, SmartKnob View comes with a 240×240 round color display but adds tactile feedback so you can change the menu when pressing the display. SmartKnob View specifications: Wireless module – LilyGO Tmicro32 Plys based on ESP32-PICO-V3-02 WiFi and Bluetooth LE SoC (May be changed to ESP32-S3-MINI-1 to enable USB HID support, once Arduino core supports it) Display – GC9A01 1.28-inch 240×240 round LCD covered by a 39.5mm watch glass on rotor Motor – BLDC gimbal motor, with a hollow shaft for mechanically & electrically connecting the LCD USB – 1x USB […]
