I like to do a lot of my electronics & Arduino work on a laptop, either on the dining room table or spread out on the living room floor. Between the Arduino, the breadboard, and who-knows-how-many components, it’s a hassle to get all the pieces moved when project time is over. I’ve seen acrylic plates for mounting a half-sized breadboard and an Arduino (here’s one at Adafruit & here’s one at Sparkfun), but they don’t appeal to me. Time to make my own.
