HackBat DIY open source pentesting device

HackBat is an open-source hardware pen-testing device designed for hackers and makers and equipped with a Raspberry Pi RP2040 microcontroller, an ESP8266 WiFi module, a sub-GHz RF transceiver, NFC, an OLED display, and more… It’s basically a DIY alternative to the popular Flipper Zero wireless hacking tool, that you can produce and assemble yourself. The Flipper Zero was the victim of its own success with the Canadian government (wrongly) claiming it could easily be used for car theft and planning to ban it (status still unclear right now),  so Flipper Zero alternatives such as the M1 multitool device got some traction as backup solutions with some extra features. But any closed-source device could eventually be banned, something that’s close to impossible for an open-source hardware device like the HackBat although policymakers could still decide to impose heavy fines if they wanted to make this type of device illegal… HackBat key […]

Blaustahl USB storage device features 8KB FRAM with up to 200 years of data retention

Blaustahl USB FRAM drive

Machdyne’s Blaustahl is a USB storage device equipped with a Raspberry Pi RP2040 MCU and 8KB of FRAM with a potential lifespan of over 200 years and designed for long-term storage of text up to about 8,000 characters. FRAM (Ferroelectric RAM) has been around for years delivering ultra-low power consumption, faster writes, and ultra-long write endurance (one million billion read/write cycles) compared to EEPROM or NOR flash, but the cost is quite higher and it’s mostly used in applications that require ultra-low power consumption and non-volatile storage write capabilities such as data logging, sensor networks, batteryless applications. The Blaustahl storage device and USB text editor is one of those. Blaustahl speciications: Microcontroller – Raspberry Pi RP2040 dual-core Cortex-M0 processor at 133MHz and 264kB RAM. Storage 4MB (32Mbit) NOR flash for firmware 8KB (64Kbit) FRAM (Fujitsu MB85RS64) Lifespan – 95 years @ +55°C, over 200 years @ +35°C Endurance – 10^12 […]

Louder Raspberry Pi is an open-source home media center that is powered by Raspberry Pi Zero and a TI TAS5805M DAC

louder raspberry pi

Louder Raspberry Pi is an open-source home media center based on a combination of the Raspberry Pi Zero W or Zero 2 W and the Texas Instruments TAS5805M DAC. It is an audio entertainment platform created by Andriy Malyshenko of Sonocotta, a Polish electronics hobbyist and maker. Louder Raspberry Pi incorporates the computing power of the Raspberry Pi Zero and the Hi-Fi audio processing capabilities of TI’s TAS5805M DAC in a compact, aluminum case. The device delivers up to 25W per channel stereo output and is powered via a 65W+ USB-C PD3.0 adapter. It is “aimed to be paired with medium-to-large speaker systems” and supports both Wi-Fi and Ethernet. The Raspberry Pi board was selected over other lightweight alternatives due to the ease of development it offers. The Raspberry Pi Zero board is small enough to make for an overall compact device and powerful enough to handle the demands of […]
