What it does
An electronics learning platform for hobbyists and engineers, with tutorials, problem-solving calculators for electronics, and a fun approach.
Practical articles, useful calculators, and the occasional bad joke. A good place to start if you want something thoughtful, useful, and immediately relevant to electronics practice. A small selection of tools that help with the numbers you reach for most often when learning or building. Plot compensator and complete loop gain for VM or PCM buck, boost, forward, flyback, half-bridge, full-bridge, and push-pull converters in CCM or DCM. This calculator plots the frequency response of low-pass filters from the entered component values. Several topologies are available, including optional component parasitics, and you can compare multiple traces. With the equivalent resistor calculator you can…from alternatronics.com

I went down the rabbit hole on a side project and ended up building this: Strange Attractors(https://blog.shashanktomar.com/posts/strange-attractors). It’s built with three.js. Working on it reminded me of the little "maths for fun" exercises I used to do while learning programming in early days. Just trying things out, getting fascinated and geeky, and being surprised by the results. I spent way too much time on this, but it was extreme fun. My favorite part: someone pointed me to the Simone Attractor on Threads. It is a 2D attractor and I asked GPT to extrapolate it to…

Autism Simulator▲779Hey all, I built this. It’s not trying to capture every autistic experience (that’d be impossible). It’s based on my own lived experience as well as that of friends on the spectrum. I'm trying to give people a feel for what masking, decision fatigue, and burnout can look like day-to-day. That’s hard to explain in words, but easier to show through choices and stats. I'm not trying to "define autism". I’ve gotten good feedback here about resilience, meds, and difficulty tuning. I’ll keep tweaking it. If even a few people walk away thinking, "ah, maybe that’s why my coworker struggles in those…
