Recently I purchased enough parts to make 10 Arduinos, following this tutorial.
The reason for this is that you get a price break on most parts when buying 10 or more.
Because of this, I was able to get the cost of each one to under $10, not including some parts I already had. This will save me a lot of money in the long run.
Looks great on those Perma-Proto boards.
Adafruit Perma-Proto Half-sized Breadboard PCB – 3 Pack! Customers have asked us to carry basic perf-board, but we never liked the look of most basic perf: its always crummy quality, with pads that flake off and no labeling. Then we thought about how people actually prototype – usually starting with a solderless breadboard and then transferring the parts to a more permanent PCB. That’s when we realized what people would really like is a proto board that makes it easy!
