You need something with a big screen so you can see what you're engineering, and all the computer companies got together and made a consensus that they would no longer allow you to have that. Get a used LG Gram with a 17" screen for about $500. Rip out the camera and microphone and any other junk that's not supposed to be in there and sell it to recoup some of the cost. Maybe resell the battery too since anywhere that has a desk also has a power outlet.
