Presenting the Retirement Gift

Very nervous me as I explain to the whole department my little idea...

I present the project to the crowd and hear people gasping in amazement.

And then I go on to explain why I built this scale model as nobody is aware of my motive.

I call my colleague and friend Claude Vaillancourt to come up in front, he is suspecting something...

I never heard such a loud applause with me upfront when I announce that to the audience that it is a retirement gift on behalf of everyone, took me by surprise to be honest!

Me and the MedStation's, very proud of what I was able to accomplish.

Attaching the eDrawer to the Chassis

While attempting to glue the eDrawer to the Chassis I realized there was a small gap and things would not properly align. To my dismay, the wires from the Arduino Nano was the cause of the issue. I took out my Dremel drill and carefully made a notch on the right side. I had previously made a notch on the left side to allow the screen to fit properly and with all the drilling done everything fit properly! With some elastic bands I superglued everything together and let it dry for the night.

Installing the Electonrics

Today I completed installing all the electronics using hot glue to keep everything in place and installed two grey panels to cover up holes in the back where the micro SD card and mini USB port are located. Not much space remains with all that wiring!

Soldering Complete

After spending 2.5 hours last weekend to solder all the parts and triple check the wiring I finally completed the first electronics assembly. All that was left was to update the Arduino Nano software and update the SD card images. I was a bit afraid to destroy my PC but after taking a few precautions all went well!

Test Fitting the Electronics

Today I test fit all the electronics to make sure everything will work. I initially wanted to place a red led for the BioID and realized that the Arduino Nano was in the way! After about 10-15 minutes of trying to find a solution (and a bit of panicking) I realized that the Arduino Nano alreay has a red LED on the board and by pure luck, it was just beside the BioID lens position... A quick test confirmed that the light would emit through the hole! What a great solution, no soldering required for this small detail!

Retaining the Drawers

For quite a while I had been struggling to come up with a way to ensure the drawers would not fall out if the model was manipulated. My initial idea was to add a lip in the front of the drawer chassis which the drawer top back end would catch. While this did prove to work initially I noticed the drawers would droop down considerably. Not satisfied with the technique being used I decided to switch to using hooks and fishing lines. The tricky part of this method was to make sure each drawer would not extend more than the others... On several occasions, I had to redo the drawer lines but in the end it proved to work really well. As an added bonus I was able to make the carousel open only halfway like the real one.

Moving from Arduino Uno to Arduino Nano

While I have been testing the circuitry on a large Arduino Uno (68.6mm x 53.3mm) I need to move this project to a smaller Arduino Nano (43.2mm X 18.5mm) for it to fit inside. I also needed to stop using the built-in micro-sd card reader located on the LCD and use a dedicated micro-sd card reader so that I can position it in the back of the model for easy access. If I continued to use the LCD card reader than the micro-sd card would be sealed off and inaccessible. While it was not necessary to make it accessible I liked the idea of being able to make changes to the image files if I feel the need to do so.

Screen Bezel

After several revisions of the screen bezel I finally was able to get the perfect fit and tonight I wanted to see how the finished product would look like. I am so amazed at how this project is coming out! 

Cubie Drawers

I had been struggling for a while to come up with a way to make the cubie drawers. The real cubies have a small space around each one which separates each of them in the drawer. I tried 3D printing an outline to glue on top of the transparent plastic but I was not satisfied with the results since I could not print thin enough. I then thought of an old modeling trick which was to use a black marker to create fake grooves and this came out very well and simple to create.
