Nixie Gear Indicator Shines Bright

When you’re driving a car with a stickshift, it’s pretty easy to keep track of which gear you’re in. That can be a little bit more difficult on something like a motorcycle with a sequential shifter. [decogabry] built a neat gearshift indicator to solve this issue.

An ESP32 devboard is used as the brain of the build. It’s paired with an ELM327 dongle over Bluetooth, which is able to hook into the bike’s ODB diagnostic port to pick up data like engine RPM, wheel speed, and coolant temperature. The first two factors are combined in order to calculate the current gear,...

The Windows Interface You Didn’t Like, For Linux

If you were asked to pick the most annoying of the various Microsoft Windows interfaces that have appeared over the years, there’s a reasonable chance that Windows 8’s Metro start screen and interface design language would make it your choice. In 2012 the software company abandoned their tried-and-tested desktop whose roots extended back to Windows 95 in favor of the colorful blocks it had created for its line of music players and mobile phones.

Consumers weren’t impressed and it was quickly shelved in subsequent versions, but should you wish to revisit Metro you can now get the experience on Linux. [er-bharat]...

M5MonsterC5 hacking tool adds ESP32-C5 and 5 GHz Wi-Fi 6 support to M5Stack Cardputer ADV and Tab5

Developed by Laboratorium in Poland, the M5MonsterC5 is an ESP32-C5-based “Marauder” hacking tool designed to work with M5Stack Cardputer ADV or M5Stack Tab5. It gets connected to the Cardputer ADV or Tab5 via a Grove connector and runs JanOS and Project Zero for wireless security research, experimentation, and rapid prototyping with minimal setup. Built around the ESP32-C5, the device supports dual-band Wi-Fi 6 (2.4/5-GHz) and 802.15.4 (Thread/Zigbee) to the M5Stack devices. Key features include multi-channel deauthentication with 5 GHz support, Evil Twin and phishing captive portals, WPA3 SAE overflow attacks, wardriving with GPS logging and WiGLE-compatible exports, passive sniffing, Karma...

Raspberry Pi AI HAT+ 2 review – A 40 TOPS AI accelerator tested with Computer Vision, LLM, and VLM workloads

Raspberry Pi sent me a sample of their AI HAT+ 2 generative AI accelerator based on Hailo-10H for review. The 40 TOPS AI accelerator is advertised as being suitable for LLMs (Large Language Models) and VLM (Vision Language Models), while delivering about the same performance as the first-generation AI HAT+ (Hailo-8) for AI vision/computer vision models. After going through an unboxing, I’ll assemble the AI HAT+ 2 to a Raspberry Pi 5 with 2GB of RAM fitted with a Raspberry Pi Camera Module 3, before quickly checking whether AI vision models work as expected, and spending more time on testing...

WisMesh 1W Booster Starter Kit targets high-power Meshtastic solutions

RAKwireless WisMesh 1W Booster Starter Kit is a high-power Meshtastic solution based on Nordic Semiconductor nRF52840 wireless SoC, Semtech SX1262 RF transceiver, and SKY66122 power amplifier for extended mesh range. It’s built from three modules from the WisBLock IoT ecosystem, and besides a power amplifier for longer Tx range and better penetration through walls, it also features an integrated RF filter for enhanced reception performance. It offers an alternative to the LILYGO T-Beam 1W with an ESP32-S3 + Semtech SX1262 LoRa transceiver +  PA+LNA design, which we covered just last week. WisMesh 1W Booster Starter Kit specifications and technical details...
