Soldering irons and their tips come in a wide range of formats and styles, with the (originally Hakko) T12 being one of the more interesting offerings. This is because of …read more Continue reading Understanding the T12 Style Soldering Iron Tip
Large language models (LLMs) are wholly dependent on the quality of the input data with which these models are trained. While suggestions that people eat rocks are funny to you …read more Continue reading Examining the Vulnerability of Large Language Models to Data-Poisoning
The [Denki Otaku] YouTube channel took a look recently at some stepper motors, or ‘stepping motors’ as they’re called in Japanese. Using a 2-phase stepper motor as an example, the …read more Continue reading Stepper Motor Operating Principle and Microstepping Explained
In his most recent article, [Ken Shirriff] takes a break from putting ASICs under a microscope, and instead does the same in a proverbial manner with the word ‘mainframe’. Although …read more Continue reading How the Main Frame Became the Mainframe: an Etymological Dissertation
Is fire conductive? As ridiculous that may sound at first glance, from a physics perspective the rapid oxidation process we call ‘fire’ produces a lot of substances that can reduce …read more Continue reading Is Fire Conductive Enough To Power a Lamp?
Crystal oscillators are incredibly useful components, but they come with one little snag: their oscillation is temperature-dependent. For many applications the relatively small deviation is not a problem, but especially …read more Continue reading Inside a Vintage Oven Controlled Crystal Oscillator
Layer adhesion is one of the weak points with FDM 3D printing, with annealing often recommended as a post-processing step. An interestingly creative method for this was published in Science Advances …read more Continue reading Using Microwave Heating to Locally Anneal CNT-Coated FDM Prints
When considering our favorite spy movies and kin that involve deep-sea diving, we’d generally expect to see some high-end watch that costs thousands of dollars and is specially engineered to …read more Continue reading Taking A $15 Casio F91W 5,000 Meters Underwater
Although DIY PCB making has made great strides since the early days of chemical etching, there’s one fly in the ointment: vias. These connect individual layers of the board with …read more Continue reading Electroplating DIY PCB Vias At Home Without Chemical Baths
As the most important muscle in our body, any issues with our heart are considered critical and reason for replacement with a donor heart. Unfortunately donor hearts are rather rare, …read more Continue reading Patching Up Failing Hearts With Engineered Muscle Tissue
