Occasionally you may find yourself in a situation where you have a huge PDF file which you want to split up into smaller chunks. While this is easy enough to accomplish using a variety of free software (or you can use the full version of Adobe Acrobat) you may find that the file has been secured with a password.
There are a number of programs which will unlock these files for you but, in most cases, you’ll need to pay for them. There are some free online services for relatively small files but here’s one which will certainly unlock files which are up to 10mb in size - maybe more. Just choose a file to upload from your computer and click the unlock button then wait for the link to appear, to download your unlocked version of the file.

Filtering an Excel spreadsheet to show just the rows you want is relatively easy to do, simply by using the AutoFilter function. But what if you find yourself in a situation where you want to filter your results to only show rows where a cell has a particular background colour?
Here’s a neat and not too difficult to follow way of doing that. These instructions apply to all versions of Excel up to XP/2003 but should be easily adaptable for use in later versions. [Read More…]

I recently started getting Georgi to roll a small ball under his feet as I figured it would help him to regain a little bit of control over his legs. He seems to enjoy it but the problem is that he currently has such poor control that the ball keeps rolling away.
I was thinking about buying a wok or something to make the ball roll back but I think I’ll try a large frying pan for the time being. Even a large plate would probably do the trick - a wok’s probably too convex for him to roll his foot around in, come to think of it.
I wondered if this was some sort of recognised exercise so I went looking and found this excellent set of [Read More…]

<< Part 2 || Part 4 (coming soon!) >>
In part 2 of this project I decided to change the design to use Unistrut instead of welded box section. Well, because I can I’ve decided to revert to using box section mainly because I have someone who is willing to build it for me, albeit with a much simpler design. The other reason is that, although the Unistrut design is quite sound I’d need to import the hand winch - maybe the pulley wheels too BUT I think it could be built without those now, and just have the wire rope running around metal posts with some PTFE tape wrapped around them.
Once I’ve got Georgi’s gait trainer built I’d like to go back and redesign the Unistrut version, but here are the drawings for the latest incarnation. [Read More…]
