i see a lot of grey hair in the embedded systems world. my vantage point is probably skewed but it seems that bare metal skills are getting rare. my client ask me how to find new folk and i really can't say... amazing people on twitter though. all are busy.

This sounds like something I'd be super interested in; I want to develop my low level bare metal understanding but there's only so much I can do by myself with ebooks and video tutorials!

What's the closest thing you've already done? There are many avenues. Personally I think the key element is to really understand a simple CPU + Bus system. The old farts all started out like that. Get in trouble, then get out of trouble.

I took a quick look at your website. What did you use to program the ATTiny85?

First, obligatory caveats that the website is many years out of date and I will overhaul it completely...someday. Were you looking at the BLAMP tiny85 project from 2013? That would have been done with the Arduino IDE and this page that was relatively new:

Programming an ATtiny w/ Arduino 1.6 (or 1.0)

This tutorial shows you how to program an ATtiny45, ATtiny85, ATtiny44 or ATtiny84 microcontroller using the Arduino software. These are small, cheap ($2-3) microcontrollers that are convenient for…

Since then I've done AVR projects in Atmel Studio/Microchip Studio, & some quirky proprietary ARM chips through Keil Compiler. ESP32s in PlatformIO. Usually in gcc C/C++—assembly language only when inheriting an existing project. Inexperienced w/ debugging in-circuit & makefiles.
