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 […]

Linux 6.5 release – Notable changes, Arm, RISC-V and MIPS architectures

Linux 6.5 release

Linus Torvalds has just announced the release of Linux 6.5 on the Linux Kernel Mailing List (LKML): So nothing particularly odd or scary happened this last week, so there is no excuse to delay the 6.5 release. I still have this nagging feeling that a lot of people are on vacation and that things have been quiet partly due to that. But this release has been going smoothly, so that’s probably just me being paranoid. The biggest patches this last week were literally just to our selftests. The shortlog below is obviously not the 6.5 release log, it’s purely just the last week since rc7. Anyway, this obviously means that the merge window for 6.6 starts tomorrow. I already have ~20 pull requests pending and ready to go, but before we start the next merge frenzy, please give this final release one last round of testing, ok? Linus The earlier […]

Snagboot is an open-source cross-vendor recovery tool for embedded targets


Bootlin has just released the Snagboot open-source recovery tool for embedded platforms designed to work with multiple vendors, and currently STMicro STM32MP1, Microchip SAMA5, NXP i.MX6/7/8, Texas Instruments AM335x and AM62x, and Allwinner “sunxi” processors are supported. Silicon vendors usually provide firmware flashing tools, some closed-source binaries, that only work with their hardware. So if you work on STM32MP1 you’d use STM32CubeProgrammer, while SAM-BA is the tool for Microchip processors, NXP i.MX SoC relies on UUU, and if you’ve ever worked on Allwinner processors you’re probably family with sunxi-fel. Bootlin aims to replace all those with the Snagboot recovery tool. The Python tool is comprised of two parts: snagrecover using vendor-specific ROM code mechanisms to initialize external RAM and run the bootloader (typically U-Boot) without modifying any non-volatile memories. snagflash communicates with the bootloader over USB to flash system images to non-volatile memories, using either DFU, USB Mass Storage, or […]

OSD62x SiP combines TI AM62x processor with LPDDR4, EEPROM, PMIC, and passives into a single package

OSD62x system-in-package

Octavo Systems OSD62x is a system-in-package (SiP) combining the Texas Instruments AM62x processor with LPDDR4 RAM, EEPROM, power management, oscillators, and passive components, plus optional features such as an RTC and an 8-channel ADC. At least that’s true for the OSD62x Max Integration SiP (22×22 mm BGA), but Octavo Systems also have a smaller 14x9mm package called the OSD62x Size Optimized with “just’ the AM62x processor, LPDDR4 memory, and passive components.

TI unveils ULC1001 ultrasonic lens cleaning chip for self-cleaning cameras

TI ULC1001 self cleaning camera

Texas Instruments (TI) has introduced the ULC1001 digital signal processor (DSP) ultrasonic lens cleaning (ULC) technology designed – when combined with DRV2901 piezo transducer driver – for self-cleaning camera systems to quickly detect and remove dirt, ice, and water using microscopic vibrations. Cameras used in the automotive, industrial, robotics, and smart farming industries may require cleaning from time to time and that usually means manual cleaning leading to potential downtime, higher maintenance cost, and so on. It could also be done through mechanical parts but that adds further complexity to the system, so instead, Texas Instruments ULC1001 and DRV2901 combo enables cameras to rapidly self-clear contaminants using vibrations to eliminate debris. The datasheet describes the ULC1001 as a “Configurable Ultrasonic PWM Modulator With I/V Sense Amplifiers” with the following specifications: Integrated Programmable Cleaning Modes Water (expelling) Deice (melting and expelling) Mud (dehydrating and expelling) Auto-Cleaning (detecting and expelling) Custom Cleaning […]
