GSChem is an electronics circuit design program for Linux & WIndows that is available in the Repositories with Debian based distributions ( I am using Lubuntu 13.10)

The software allows for the drawing of circuits, insertion of components and has the standard box at the bottom which you will find within professional designs,  the box gives the title of the work, who produced it, date, revision, and page of page,  which is used so you know which version of a design you are looking at.

As you can see I have drawn a simple NAND gate circuit,  I know the filename is AND, this was due to an error on my part,  the gate is indeed a NAND gate and I have included the appropriate truth table to show inputs / outputs.

Output can be printed or saved as png format.  Blank pages (including the box in the lower right) can also be printed for off line design.   There are many features which I have not started to look at yet.

I found a youtube video (below) which seems to show how to use some of the features.

I will look in to this further,  right now I am just going to use it for basic circuit design.

MINI PRODUCT REVIEW AMAZON BASICS 4 PORT USB HUB

Product : 4 port USB Hub

Supplier Amazon UK

Cost : £8.32 *

* At the time of writing

This is a really nice little hub,  I have two, one for my main desktop PC and another in my box of bits for my Raspberry PI. It is NOT a powered hub,  but does the job.  On my PC I can connect several USB sticks, printer and it works fine.

On the Pi  have have a keyboard and mouse plugged in to the hub, which is attached on the Model B to the lower of the two USB ports on the PI,  the upper port has my Wifi Dongle attached.  It all works fine, I can plug a USB flash disk in if need be.

There is an orange LED to indicate when it is plugged in.

The limitation with the pi is power,  hence for more power consuming devices a powered hub is recommended.

In all a good buy and its small enough to go in a larger box of bits which is handy.  I intend to buy a few more at some point.

Makes a good addition to your pi kit, without having to worry about an extra PSU.

Tested on Raspberry PI Model B

Just a quick test of WP-SynHighlight plug in this allows the insertion of source code in to word press blogs and preserves indentation and highlighting.

Source code

import datetime
import time
from datetime import datetime
 
now = datetime.now()
 
for x in range(0, 100):
 
	time.sleep(5)
	print str(now.minute) + " : " + str(now.second) + " : " + str(now.microsecond)
