What the heck is PIPduino?

I realized after I finished the Jeep's steering servo controller that our Pro Mini was missing something.

I built this icky baseboard for it with a protoboard. What was missing? Can you tell?

Power and ground rails and a voltage regulator, that's what.

So I made this 'duino clone for Putting In Projects, aka PIPduino.

Before PIPduino (ick). And after (ah, much nicer).

Here's the board up close and personal. Color coded pins, every digital and analog has a 5V/GND pin. Dedicated I2C, SPI and Serial/FTDI ports. Flexible power options.
Introducing PIPduino

Is it sacrilege to say that I want an Arduino without shields?  Or that I want an I2C port with power rails and pull-up resistors? A combination ISP/SPI port so I can connect to SD cards easily? Digital and Analog pins with power rails?

I wanted an Arduino-compatible board that can be embedded in projects just by making cables and attaching power and sensors/drivers. Now I have one.

What do you think? Would you buy one of these? I'll be selling them on Tindie soon.

Discovering Linux Mint 14 EOL

A little over a year ago, I converted to Linux Mint 14 for good, leaving Windows (mostly) behind.

Despite some initial bumps (and whining for which I remain deeply embarrassed), I've been quite happy with it and it is an excellent platform for my hobby electronics and robotics as well as for general use.

In the process of reworking my backup strategy, my attempted installation of rdiff-backup with apt complained about unsigned packages. Then bombed out...
