I'm working on the vision component of a drone racing stack. Could I use GS to render my living room as a digital playground to train my vision models in?

I know nothing about the technology but the alternative is creating a 3d model of my living room which is also outside my skill-set.

What a lot of commenters cheering this headline might not know is that there is only one single internal road connecting east and west canada which regularly closes. Most commercial routes go through the US. Don't believe me? Route Ottawa to Vancouver in google maps.

This move would amount to throwing rocks from a glass house.

I definitely tried to web search with ChatGPT a few weeks ago and it couldn't. I don't think I'm making this up. Unless I suffered a TBI.

Excited to see how this compares to Perplexity or Gemini. I remember that ChatGPT used to be able to search the web, but last I checked it it couldn't. I wonder why they removed that feature

I'll tell you how I learned, I got thrown head-first into a network switch design. I knew almost nothing about networking.

The most useful resource while I was learning was RFC1812 "Requirements for IPv4 Routers" [1]

Its an ancient document written the same year I was born detailing how future routers should be built on this relatively new thing called the internet. The language is highly approachable and detailed, often explaining WHY things are done. It is an awesome read.

To be honest you don't need to finish it. I only read the first few chapters, but I googled EVERYTHING I did not understand. The first few paragraphs took several hours. Talk to LLM's if you need a concept explained. Take notes. In a few days you'll have a very solid grasp.

I think he meant 100MHz. In case he actually meant 100GHz, I would gently remind him that light only travels ~3mm in 10ps

Welcome to Hardware Design! The open-source toolchains come from hell. The closed-source options are supremely expensive and not much better

They don't call it EasyWare

I like the RP2040 2 years ago

I also happen to be working on an ultra-low power project with an ESP32.

It is hard to beat that 5uA deep-sleep current!

No love for NXP in this thread? They make a very similar peripheral called FlexIO [1] on devices like the K32.

[FlexIO is a] Highly configurable module providing a wide range of functionality including emulation of a variety of communication protocols

It is extremely capable! I have used it to hack together an octo-SPI... which stretches the definition of the S in SPI ;)

I think an electric shock would go a long way.

Years back I tried to make a phone case that would shock me at random while using it. The idea was to replace the dopamine hit you get from checking your phone with a twinge of anxiety and dread.

I never finished the project. Turns out generating high voltages requires tall inductors, which generally make a phone case unacceptably thick.
