There are plenty of different buses, these six are the most common ones and I knew none of them before I started embedded development to build my own electric cars. CAN-Bus is the most common one today, Automotive Ethernet is rising fast du

I hope this helps someone who moves from buisness programming (SaaS, startups) to embedded. That was my route and I wasted a lot of time on these: - input filtering: this cost me a week I am sure, a 1 is not necessarily a 1, it might be 0.9

It's a high level overview, a starting point for googling the keywords really, there will be future videos illuminating separate aspects in more detail. I spent 5 years building my own electric cars and am now sharing everything I know

Thank you for your feedback. I will make the highlighting more obvious, that's easy. For the questions, maybe I should show supporting sources when the user gave a wrong answer because that's where the learning happens! For the sp

If you are interested in batteries, the C-rate should interest you. I build my own electric cars, and am now condensing important theory into these 3min - 5min videos. This one is about the c-rate for batteries. Big auto and battery manufac

I've put a Nissan Leaf on a bench before and run it just like you did and would never do it again. This approach is so much harder than it seems. "once everything works then it'll be straightforward to remove what's left

Sure, they say it costs up to twice as much, and that is true if you rapid charge all the way to your destination. If you have any sort of home-charging arrangement the article is disingenuous? They give Diesel as £0.125 per mile and Petrol
