Re: More printing on the Pi bottom please

The bit that got me was asking for coloured labels. That is a complex change and will add to manufacturing costs.

Shame the GPIOs can't be labelled too...
If they coloured the ground, 3v3 and 5v the gpio would be easier to navifate.
And print a pink unicorn, too.

Re: Raspberry pi 3b+ as a portable console/PC

A Pi3b typicallyaverages 0.4 - 0.7A under general use. Well use the mean of that and say 0.55A Watt hours is more reliable than mAh so we'll convert that as well. 24,000mAh @ 3.7v comes to just under 89Wh. The Pi uses 5v, and it works out to 2.75W h FTFY (The Pi's consumption, 5V x 0.7A, is in Watt...

When you are on Debian but not Raspbian, and Squeeze rather than Stretch, and a non-DHCP network, you are probably pretty much on your own.

Re: Testing App Reading GPIO Pins

If your code is written in a suitably modular style, possibly using the benefits of an object orientated design, it should be easy to add software input simulation to your GPIO reading routines (or to display the outputs of GPIO setting routines). That is useful for testing your logic and human inte...

If you can, get a Class A1 (or A2) SDCard rather than Class 10. It should last longer (and perform better) in the Pi environment.

In all honesty, the Pi was never intended to run software, it was supposed to make it easier for people to learn how to make their own.

One of the black wires, which should I think be negative, goes to the positive rail.

Depending on the breadboard, the power rails along the edge may or may not be continuous across some or all of the gaps.
