For version two of my mecanum robotics platform I’ll be providing a 3D printable version of the rollers for dual extruders. The outer shell of the roller can then be printed with a flexible rubbery filament to aid in increasing the friction between the roller and the ground. Otherwise you’ll have to spray or coat the roller in a material like plastidip.
Recently had to edit a few protected PDF documents where the sender didn’t have access to the passwords, most likely due to using an automated PDF generating service.
As the article was written 4 years ago I thought I would write an (easier) update to the process.
If you haven’t already.
homebrew is a nice package manager for OSX that allows you to install/compile generic unix utilities ported over to OSX.
Then on the command line:
$ brew install mupdf
Then clean your file
$ cd /directory/your/pdf/is/in
$ mutool clean protected.pdf clean.pdf
Here we run the mutool binary with the command subset ‘clean’ and pass it in the protected file’s name, then as the last argument we supply the name of the new file mutool will save the password protection stripped pdf to.
Cmon, you guys don’t need any instructions.
And in-case you do, you probably can just use whatever built in package manager your distro uses to install mupdf.
Happy non-DRMd PDF to you!
As there is no html element wrapping the comments area with padding or margin the Disqus WordPress plugin when used out of the box does not display correctly in the latest WordPress theme, 2014.
In the sidebar menu go to Appearance > Edit CSS and then paste in the CSS below. If you have existing CSS make sure you don’t overwrite it.
As the theme uses media queries to adjust the padding around the content area so must we for the commends container. It would be easier to just add the Disqus comments css selector to the existing CSS file, however modifying the theme’s base css file would leave us vulnerable to updates. Which would clear out any changes we’ve made. So instead we’ll use a spiffy new feature of WordPress to just add our own custom CSS to the page.
Here is the current Solidworks CAD mockup of the platform. I’ll be receiving some test hardware soon to hopefully help prototype the first working version on the mk2 of the design.
Details of the build will be posted on the blog and instructionalized on the MEPmk2 wiki page when the design becomes more solidified.
I’ll be organizing and posting the source files for the design ( STL, and solidworks files ) on github soon So people can track progress there and potentially print/laser out their own (probably not finalized version)
