ESP8266-powered Netgotchi network security scanner aims to protect your home network

netgotchi security scanner

The Netgotchi network security scanner is a simple, compact device based on an ESP8266 wireless microcontroller with a single goal: to defend your home network from intruders and potential bad actors. It is described as “Pwnagotchi’s older brother,” a network guardian that keeps your network safe instead of penetrating it. If you are unfamiliar with Pwnagotchi, it is an A2C-based (advantage actor-critic) “AI” that can penetrate Wi-Fi networks using WPA key material obtained from passive sniffing or de-authentication attacks. The Netgotchi is a reverse Pwnagotchi that alerts you to intruders or breaches in your network. It runs on a simple microcontroller and cannot employ reinforcement learning like the Pwnagotchi. Rather, it pings the network periodically and reports any new potential security threats. The device’s design is as simple as its purpose. It is an ESP8266 microcontroller connected to an OLED display and running an Arduino .ino script, enclosed in a […]

The first Realtek RTL8157 5Gbps Ethernet to USB 3.2 adapters are now available for $35

RTL8157 USB 3.2 to 5GbE adapter

WisdPi WP-UT5 is the first Realtek RTL8157 5Gbps Ethernet (5GbE) to USB 3.2 adapter to make it to market, following the launch of Realtek RTL8126 5Gbps Ethernet PCIe and M.2 adapters last June, and the announcement for both the RTL8126 and RTL8157 chips at Computer 2023 last year. While the RTL8126 dongles and cards are fairly cheap at around $16 on average and as low as $12, the WisdPi WP-UT5 is sold at a premium for about $35 on AliExpress, but we can expect the price to down come as more companies introduce 5GbE to USB 3.2 adapters. For reference, the 2.5GbE variants based on RTL8156(BG) can be had for about $20 on Amazon. WisdPi WP-UT5 specifications: Chip – Realtek RTL8157 USB USB 3.2 Type-C female port A-C and C-C cables to support hosts with USB Type-C or Type-A ports Ethernet 10/10/100/2500/5000 Mbps Ethernet Supports 5G Lite (2.5Gbps data rate) […]

MILK-V Jupiter review – A RISC-V mini-ITX motherboard and PC tested with Ubuntu-based Bianbu OS

Milk-V Jupiter RISC-V computer review

In this review or preview of the the Shenzhen Milk-V Jupiter RISC-V mini-ITX motherboard, I’ll assemble the motherboard into a mini-ITX chassis, before installing the Ubuntu 23.10 Mantic-based Bianbu OS optimized for RISC-V platforms, and testing the device to see how much progress has been done on RISC-V since I tested the StarFive VisionFive 2 SBC with Debian 12 about 18 months ago. In the first part of the review, we checked out the Radxa ROCK 5 ITX (Rockchip RK3588 Arm) and Jupiter (SpacemIT K1 RISC-V) mini-ITX motherboards with specifications and unboxing, and the Auriga 6-Bay NAS mini-ITX chassis used in this review. I planned to start with the Radxa ROCK 5 ITX, but due to logistics and technical issues, I went ahead testing the RISC-V motherboard first. Installing Bianbu OS to the Jupiter RISC-V motherboard The board does not come with storage, so no operating system is installed. So […]

Linux 6.10 Release – Notable changes, Arm, RISC-V, and MIPS architectures

Linux 6.10 Release Changelog

Linux Torvalds has announced the release of Linux 6.10 on LKML: So the final week was perhaps not quote as quiet as the preceding ones, which I don’t love – but it also wasn’t noisy enough to warrant an extra rc. And much of the noise this last week was bcachefs again (with netfs a close second), so it was all pretty compartmentalized. In fact, about a third of the patch for the last week was filesystem-related (there were also some btrfs latency fixes and other noise), which is unusual, but none of it looks particularly scary. Another third was drivers, and the rest is “random”. Anyway, this obviously means that the merge window for 6.11 opens up tomorrow. Let’s see how that goes, with much of Europe probably making ready for summer vacation. And the shortlog below is – as always – just the last week, not some kind […]
