Waking from my winter hibernation

A lot of great projects get sidetracked, I have been busy this winter with various items. Progress on enclosing my 3D printer has technically continued.
The making of the enclosure has slowed down but things around it have progressed, a sort of feature creep. I realized that I could make things better with a slight rearrangement in my goals.
When I reorganised the area to accommodate my larger printer. I saw an opportunity to add a cool location for my smaller Fabrikator mini printer.
It all started by fitting some shelves and that sort of snowballed.

I removed the old hood and put up a new shelf a little to the right.

And the new shelf

The other major change was I picked some  parts and assembled a new computer and brought down my older computer to the work area because this had a better video card it seemed sensible that I got a better second LCD screen .

To enable printing to my Fabrikator mini I mounted a Raspberry Pi up on the wall and added a camera so I can see monitor it on one of my screens while I am busy doing other things.

I made a space for my fume carrying hose from my larger printer so it could be nicely sandwiched straight up the wall and the shelf. I added a power bar that I can easily access.

The best laid plans of touch screens and men.

I  had a few more things to do, I wanted to paint the hinge and brackets black, but I was so excited to get it working I jumped to the configuration of the software.

Now that Octoprint has plugins and one of them is the touchUI designed for LCD touch screens etc, I went through the steps of setting up the image on the Pi. I used Jessie Lite on to an 8GB SD card.
I went back to the computer and opened a browser and put in Local.Pi and connected from the browser. The OctoPrint GUI was now visible.

I then installed the Touch UI plugin.

The next step was to see the interface on the Raspberry Pi. This meant that the Lite in Jessie Lite was not going to cut it, I needed to run a browser, but Jessie Lite does not have X system that gives graphics.  I used the script to expand and load the X part of Jessie that was missing from Jessie Lite.

In all fairness, there was a warning that said something to the effect of loading more than Jessie Lite and it would probably not work well.

I’ve been framed

I like looking at Thingiverse and I was browsing for ideas. I wanted to enclose the Pi in an enclosure and I would 3d print the enclosure. I found this enclosure and it was perfect. It is for the Pi one and can be found at

I chose it because it had 4 lugs to help with mounting.
I found that my interface board interferes with it so I cut a small slot which is even better. Now the HDMI socket is not taking all the strain.

The L word

The  shape looked like this, next I added inserts

Frame that can be customized
Holy Customisation Batman!

It feels like designing something out of Meccano.
Maybe somewhere in my subconscious, that is why I added so many holes.
One thing I noticed was that fewer holes meant a quicker print time.

Then the joining piece was added. It seemed slightly wonky but still pretty sturdy.
I checked and it fits the gully around the centre of the display, with the exception of the flat cable that goes to the side of the display. There appears to be a slight twist that became more pronounced after a day or two.

Plan B from outta da kitchen

I have several Raspberry Pi boards (it seems every time I buy one they release another one) but no real finished project. I was thinking that I have this Raspberry Pi B model one sitting idle and if I didn’t do something with it soon they will release the Pi sub zero and it will never go in a project because the new Pi will be cheaper and more capable than good old version one.
I originally planned to use this Pi as a kitchen computer. But issues with the back light not turning off completely when the screen was off (asleep) made me put that project on hold.

So the first step was to decide what to do with it. After printing from an SD card to my 3D printer I started to think about the possibility of untethering my printers from my desktop computer. I was looking around and saw the  Octo-pi has come along quite a lot and they now have a touch interface plugin.

I previously designed a holder for the kitchen computer that the display sat on a lip but I wanted to 3D print something and that would be complex.
I also want to attach the Raspberry Pi.
