Test and configure LCD screen

Ok, so I finally think its time to test the LCD Screen; so I plugged it in and...

Nothing happened!

I did some reading online and on the RepRap Wiki I found a quote that reads:

Some versions of this board have the notched connectors the wrong way around. If your controller only flickers and beeps, cut off the notches on the cables and insert them upside down.

Ok; that doesn't sound good!

The only way I could think of to prove if mine had this issue was to identify where the GND pin was located and cross reference that with the MKS Gen-1. So I got out my multimeter, set it to resistance, connected my black lead to the SDCARD slot on the back and found the GND pin...

I cross referenced it with the MKS pin layout (GND Marked in yellow arrows) and found that my connector was fitted the wrong way around.

I had to file/cut off the block at the back of the connector, but after that, the LCD screen powered up :)

In Arduino IDE, I installed the U8glib and U8glib-HAL drivers and enabled this setting:

// RepRapDiscount FULL GRAPHIC Smart Controller

// https://reprap.org/wiki/RepRapDiscount_Full_Graphic_Smart_Controller

#define REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER

I uploaded it to my printer and... It works.

Lastly. I built a temporary cardboard enclosure for it until I can print one:

Pretty huh? :)

Discord Gateway for MQTT

I have created a new organisation on Github today as a place to add automation scripts and the first one I will add is a gateway for Discord. This core of this script was originally created when I needed to send crash alerts from an application I had written to my phone so that could act upon them quickly. This proved useful and I added it to additional scripts and applications, but found that it was a bit limited if I wanted the alert to be logged elsewhere so I updated my apps and scripts to send to MQTT. Once my alerts were in MQTT I could pick them up from NodeRed and perform various actions; but I missed having them arrive in Discord, so last night I created an MQTT-2-DISCORD module that includes support for multiple discord channels. Installation is fairly simple and I have documented the process in the README.md file associated with the repository. After installation, visit Discord and obtain a webhook for the channel you want to recieve messages into. You can name t...

LSP templates

I took a step back with my LSP and decided that what I really need is a template based system for building responses. Previously I had started creating the JSON on the fly but realised that the jsonrpc specification has what it called interfaces which are basically templates, so I wrote a Type that allows you to add templates and variables and then it joins them all together for you. It works well but I might find a better way at some later time. After getting the template system working and removing some debug messages that I think might be inadvertently picked up as responses. For reference, the LSP receives an "initialise" message from the client that contains a lot of data. In my case it was over 4k in size. The LSP then returns an "initialized" message and receives confirmation from the client in the form of an "initialized" notification. The "initialize" and "initialized" messages are very similar. Both contain "jsonrpc"...

A Hobbit house for my Tortoise

We moved house earlier this year in the middle of lockdown! It was rather unpleasant and a story for another time, however we realised recently that we didnt have a shed and therefore no where for the tortoise to hibernate this winter! So pencil went to paper and I drew this: The wife laughed, but I convinced her I could make it, so the next step was to draw up some plans: They are quite rough, but had everything I needed to build it, so I started by building a scale model: I was pretty happy with the model and the Wife was intrigued, so after a trip to various DIY stores and a few orders on Amazon, I finally built it: It took me ages to figure out how big the tiles should be. I cut three widths of three heights in two different coloured sheets of roofing felt and stapled them to the roof (which was already covered in felt). A fake grass door-mat finished it off nicely. I think it came out pretty well: I wrapped it in cling fi...
