The DIY Life ☛ I Built a Pi 5 Hey Hi (AI) Chatbot That Talks, Blinks, and Looks Around!
There’s something fun about bringing tech to life, literally. Today’s project is all about that, building an Hey Hi (AI) chatbot that blinks, looks around, and even talks back using a set of custom animatronic eyes and a mouth made from a Neopixel LED light bar.

CNX Software ☛ HackStar – An RP2040 or ESP32-S3-based USB hacking cable/dongle (Crowdfunding)
HackStar is an ethical hacking tool based on Raspberry Pi RP2040 or ESP32-S3 in a USB cable or dongle form factor for education, pentesters, and makers. While the email I received claimed the HackStar was the “first-ever production-ready ethical hacking product on Kickstarter”, we’ve written about a range of hacking devices based on ESP8266, ESP32, and/or RP2040 microcontroller(s) such as the popular Flipper Zero, the BUG USB stick, nRFBOX V2 ESP32 wireless hacking tool, ESP32 Marauder Double Barrel, HackyPi USB adapter, and many others.

Crossover ☛ Functional Implementation of the 6502 Microprocessor in LabVIEW
This post marks a significant milestone in my personal project: the development of a complete Commodore 64 (C64) emulator entirely in LabVIEW. After successfully implementing the SID audio chip, the focus shifted to the core component: the CPU, the MOS Technology 6502 (or its 6510 variant).
I have completed the functional implementation of the 6502 core. The primary goals were achieving maximum logical accuracy while ensuring efficient execution through a lean and optimized LabVIEW codebase.

CNX Software ☛ Nuvoton NuMicro M55M1 low-power Arm Cortex-M55 MCU enables on-device Hey Hi (AI) with Ethos-U55 NPU
Nuvoton’s NuMicro M55M1 is a low-power Hey Hi (AI) MCU that combines a 220 MHz Arm Cortex-M55 CPU with a 111 GOPS Ethos-U55 NPU to run basic Hey Hi (AI) tasks on-device. It specifically targets small IoT and embedded devices that need low-power voice, audio, or simple image processing. The chip embeds 1.5 MB RAM, 2 MB flash, and supports external OctoSPI/HyperRAM memory. Connectivity options include Ethernet, USB-OTG, CAN-FD, I3C/I2C/SPI, SDIO, and an 8-bit camera interface, along with ADCs, DACs, comparators, PWM, and multiple low-power modes.
