The article reports 4,653 access points and 5,848 Bluetooth devices, including 673 open networks and a beacon flooder that advertised 77 fake networks. It also explains why rotating addresses can inflate device counts and documents important limitations, including 2.4 GHz-only WiFi coverage. ### Source excerpt Seven days of passive listening at BSides, Black Hat and DEF CON: 673 open networks, one beacon flooder, and what it takes to count devices honestly. I have wanted to build one of these for a long time. A little screen on my bag that tells me what the air around me is actually made ...

The GPS Time Badge uses GPS data to discipline the badge's internal real-time clock, although timing accuracy was limited by the hardware and BadgeOS architecture. The author also logged GPS satellite and fix-quality data and used Claude to create an interactive visualization, highlighting data visualization as a practical use of AI tools. ### Source excerpt In the midst of our AI slop revolution, traveling to the West coast for Open Sauce this past weekend was the perfect antiseptic for rising costs, summer heat, and online divisiveness. It's ironic, then, that I used Claude to vibe code my Tufty GPS Time Badge. Partly due to time constraints, and partly because I wanted to see if I could complete a personal project end-to-end, without editing a line of code, I throw my requirements at Claude and ultimately came up with this 2141-line MicroPython app for Pimoroni's Badgeware ecosystem. ## Inkplate: Open-Source ESP32 E-Paper Development Boards DevFeed: [Inkplate: Open-Source ESP32 E-Paper Development Boards]() Original publisher: [Read original article]() Author: John Lee Published: 2026-05-30T00:00:00Z Content type: article Language: en Sources: [Blog on Developer Portal]() Topics: [ESP32](), [Hardware](), [Open Source](), [Arduino](), [MicroPython]() Tags: [arduino](), [blog](), [build](), [community-contribution](), [development-board](), [e-paper](), [esp32](), [hardware](), [low-power](), [micropython](), [open-source](), [projects]() ### AI overview This article introduces Inkplate, a family of open-source e-paper development boards built around the ESP32.

It introduces PWM-generated sound, notes the limitations of square waves, and moves toward generating more complex waveforms for WAV playback. ### Source excerpt The Raspberry Pico is suddenly becoming my preferred chip for embedded development. It is well made, durable hardware, with a ton of features that appear designed with smartness and passion (the state machines driving the GPIOs are a killer feature!). Its main weakness, the lack of connectivity, is now resolved by the W variant. The data sheet is excellent and documents every aspect of the chip. Moreover, it is well supported by MicroPython (which I'm using a lot), and the C SDK environment is decent, even if full of useless complexities like today fashion demands: a cmake build system that in turn generates a Makefile, files to define this and that (used libraries, debug outputs, ...), and in general a huge overkill for the goal of compiling tiny programs for tiny devices. No, it's worse than that: all this complexity to generate programs for a FIXED hardware with a fixed set of features (if not for the W / non-W variant). Enough with the rant about how much today software sucks, but it must be remembered. One of the cool things one wants to do with an MCU like that, is generating some sound. The most obvious way to do this is using the built-in PWM feature of the chip. The GPIOs can be configured to just alterante between zero and one at the desired frequency, like that: from machine import Pin, PWM pwm = PWM(Pin(1)) pwm.freq(400) pwm.duty_u16(1000) Assuming you connected a piezo to GND and pin 1 of your Pico, you will hear a square wave sound at 400hz of frequency. Now, there are little sounds as terrible to hear as square waves. Maybe we can do better. I'll skip all the intermediate steps here, like producing a sin wave, and directly jump to playing a wav file. Once you see how to do that, you can easily generate your own other waves (sin, noise, envelops for such waveforms and so forth). Now you are likely asking yourself: how can I generate the complex wave forms to play a wav file, if the Pico can only switch the pin high or low? A proper non square waveform is ## MicroPython-Ctl - a TypeScript library for talking to MicroPython devices DevFeed: [MicroPython-Ctl - a TypeScript library for talking to MicroPython devices]() Original publisher: [Read original article]() Author: Chris Hager Published: 2021-01-29T00:00:00Z Content type: release Language: en Sources: [Chris Hager]() Topics: [MicroPython](), [TypeScript](), [ESP32](), [Raspberry Pi](), [Electron](), [Node.js](), [Command-line interface](), [Visual Studio Code](), [async](), [React Native]() Tags: [async](), [cli](), [devices](), [electron](), [esp32](), [files](), [micropython](), [network](), [node-js](), [raspberry-pi](), [react-native](), [terminal](), [typescript](), [visual-studio-code]() ### AI overview The article introduces MicroPython-Ctl, a TypeScript library for interacting with MicroPython devices such as ESP32/8266 boards, Raspberry Pi Pico, Pyboard, and WiPy.
