Raspberry 6.283185307 Zero

AKA, A second post on the Raspberry Pi Zero.

It's been two months since the release of the $5.00 Raspberry Pi Zero, and I still haven't been able to buy any. As I discussed in my prior blog about it, there is plenty of discussion around the fact that, out of the box, it's not real useful without adding enough accessories to make it as expensive as any other Pi model. I certainly understand that point, but here's another way of looking at it.

If you want to learn software, buy one of the other Pi models. If you want to learn about hardware design, buy the Pi Zero and download some CAD software. Then go online and get the Pi Zero dimensions and start designing accessories for it. You can start with one of the many open source Pi Zero accessory designs, or come up with your own. Don't look at it as a system that's missing too many parts. Look at it as a base for a different type of learning.

One of the scariest things about designing a plug-in/on board for a bigger computer is the possibility of a mistake that will fry the expensive board. With the Pi Zero, you're risking $5.00.

Like I said, I still don't have one, but I've drawn up my for Pi Zero accessory:

PiZero LiPoly

It will plug right on to a Zero as a rechargeable Li-Poly power supply. Not at all a complex circuit, but it's only the first in a series. As a small board, it doesn't cost much to get fabbed, so for about the price of one PCB sized to fit the bigger Pi boards, I can get two of these.

Next, I'll design a motor driver, and then possibly an IMU, or sensor board.

If you have your Pi calculate Pi, would that Pi be Pi enough for Pi?
