+1 for DIY! Checked out your channel and site. Good stuff!
Amazing story: my mac fell of the roof of my car going 50mph (I forgot it there), and this case saved it's life. There is a dent in the screen where it landed, but there is no scratching because the case took the brunt of the damage. I will replace the screen because it reminds me of my stupidity, but the computer still works great.
Hey, there were no reflectors. And the casing was just a U shaped piece of metal from Home Depot, I can't remember what they are called but they are used in construction. The ULN2803A should work fine as long as you watch your current, though I don't have any experience with that chip.
Unfortunately that code died with my old computer :( I'm angry with myself for not backing up...
Yes 1amp approx. No transformer, just mosfets.
Thanks! Message me if you need help with any specific code
