Community-sourced design insights and troubleshooting for the TI TPS2121 power multiplexer
The TPS2121 is a 2:1 power multiplexer with break-before-make switching (2.8-22V, 4.5A, 56mΩ). Unlike ideal diodes, it actively manages input selection based on programmable priority logic while providing integrated protection.
This guide synthesizes practical knowledge, best practices, and known issues for the Teensy 4.1 microcontroller, based on extensive community discussions. It is intended for developers, hobbyists, and engineers designing circuits and software with the Teensy 4.1. The information was reviewed by a human, with summarization and structuring help from Gemini 2.5 Studio.
This is a supplemental reference guide for the bq25895, focused on practical advice, common problems, and information that goes beyond the core datasheet. It was created by summarizing forum and article posts and processed with a Gemini 2.5 pro documentation workflow.
For Circuit Designers and Firmware Engineers
This document is intended as a companion to the official Texas Instruments datasheet, not a replacement. The datasheet provides the fundamental specifications and operational principles. This guide consolidates community knowledge, best practices, and lessons learned from real-world implementations to help you avoid common pitfalls and accelerate your design process.
This guide is a summary of collective knowledge, best practices, and troubleshooting tips for the Texas Instruments BQ25185 linear battery charger, based on community forum discussions. It is intended to supplement, not replace, the official datasheet.
The BQ25185 is a standalone, single-cell (1S) Li-Ion/Li-Po/LiFePO4 linear battery charger. Its key characteristic is the integrated power path, which allows it to power a system load while simultaneously and independently charging the battery.
This guide summarizes key design considerations, best practices, and common issues for the TPS61033 boost converter, based on collective notes from datasheets, application notes, and community discussions.
The TPS61033 is a high-efficiency synchronous boost converter. It's frequently used in battery-powered applications to step-up a lower input voltage (e.g., from a Li-ion battery) to a stable, higher output voltage (e.g., 5V).
This guide to the LSM9DS1 was written with help of the datasheet, offical STMicro driver source, and other libraries. It is for low level troubleshooting and use of this sensor. Gemini 2.5 pro was used to help summarize and cross-check.
(A Merged Technical Reference Based on the Official ST Driver and Community Examples)
This guide provides a robust, end-to-end technical reference for Arduino developers who wish to perform a direct I2C implementation of the LSM9DS1. It combines the safety patterns from the official STMicroelectronics C driver with practical code examples and register maps, creating a single, authoritative resource for your project.

Platform engineering aims to scale DevOps principles, enabling developer velocity and a better developer experience. However, a common focus on the platform's internal tooling and workflows might overlook a crucial aspect: the provision of business-centric APIs that unlock broader organizational value and innovation. This guide explores potential blind spots and how to address them.
The conversation around platform engineering often centers on the efficiency of building and deploying software. But a critical question arises:
"My question to you was whether platform engineering as it is mostly portrayed today might have a little bit of a blind spot because there's not so much a focus on which APIs to provide throughout the organization to provide these options that new interesting things can happen."
This is a summarized and simplified on-page guide based on the FlyOnUI documentation, intended for use as context for LLM-assisted coding. It was created with a summarization workflow created in n8n and then summarized with Genimi 2.0 Flash, and the final document restructured and reformatted using Gemini 2.5-pro.
FlyonUI is an open-source Tailwind CSS component library. It provides semantic classes and JavaScript-enhanced components for building user interfaces.

| >>> tell me about the angles of a dodecahedron | |
| <think> | |
| Okay, so I need to figure out the angles of a dodecahedron. Hmm, first off, what exactly is a | |
| dodecahedron? I remember it's one of those Platonic solids, right? The prefix "dodeca" means twelve, and | |
| since each face is a pentagon, it must be the regular dodecahedron with 12 faces. But wait, there are | |
| different types, like irregular ones, but I think when people refer to a dodecahedron without specifying, | |
| they usually mean the regular one. | |
| Alright, so each face is a regular pentagon. That means all edges are equal in length and each internal | |
| angle of the pentagons should be the same. I recall that the interior angles of a regular polygon with n |
