>> Mine as well. In spite of that I can design electronic apparatus, layout the circuit boards, and bring them to life. I can also write firmware on any micro controller, programming right down to the metal. Typically, my designs access various sensor systems and control motors and other actuator systems. For fun I design and test solid rocket motors and fabricate all sorts of stuff in my machine shop.
Spelling capability is a very poor indicator of intelligence. <<
You managed to convey your thoughts about your skills without any spelling errors, perhaps your spelling isn’t as bad as you thought. I wish I had your skills. I could have a lot of fun doing stuff like that.
Oh, I could only wish! I turn on every spelling and grammar checker that comes within reach. ;-D
I have trouble remembering dates as well. History was always interesting, but I always scored low on tests. I can never seem to recall the dates of events. My wife can testify against me in this matter.
While technical stuff makes sense to me and stays with me while I work, I have to try really hard to appear literate. ;-D
