Hi there. it's taken 2 years but I think I have found a replacement hobby to programming. making battery cells and steam boilers lol.
Its been really fun. Im still doing or learning electronics. AUTODESK has a virtual circuits program named AUTODESK CIRCUITS here. wow is all I can say about that nice app. Its a online app no need to down load just sign up.
Here's a link to my YouTube channel if you would like to learn how to make a battery cell or maybe a mono tube rocket stove boiler.
