| | | | | My earliest electronics projects and my first robot were powered by regular alkaline batteries, and I didn't think about current or the capacity of those batteries. The batteries were prominently labeled "1.5V", and I was happy in my understanding that putting four in a battery holder got me to 6 volts; when the motors slowed down, it was time for new batteries. When I began designing my second robot, I found some 12V, 1A motors (what a "1-amp motor" might mean is a topic for another post) and promptly wasted many hours dragging parents and teachers to Radio Shack and car parts stores looking for a 12V, 1A battery. | |

| | | | | Lenovo Thinkpad X220 is one of my favorite laptop models (the other one is Panasonic Toughbook CF-19). It has a beautiful seven-row keyboard with space for all the necessary buttons- there are even separate buttons for Home, End, Pause1 and Insert! Rugged magnesium alloy case covered with some kind of rubber for better grip. A memorable appearance- an angular black rectangle that looks austere and at the same time quite retro-futuristic. And relatively powerful hardware, which can be used to this day. | |
