Default Hello from India

I'm a business grad and I've worked across many non-technical functions, however my passion has always been Electronics and DIY. I've been tinkering since I was 5 years old, mostly with my dad who was also an electronics engineer. About 2 years ago I started building digital fabrication tools and after building 2 CNCs, 1 laser engraver and a 3D printer, this year I finally took the plunge this year to become an entrepreneur and make electronics for digital fabrication tools. This is my website for now but its about to undergo a radical change - https://classbproject.com. Apart from this I do a lot of photography and I'm a very outdoor-sy person

Welcome to the forum, it's great to have another member who can produce drivers, my projects are requiring more and more current and not enough choices for higher current drivers. I'm not seeing the link to your web site, if you intended to put it in your post.
