Enchanted Objects Design Challenge - The Lode Stone

A trip up the fell

Matilda looked serious, she was dressed in a boiler suit, boots and a hard hat, she was leaning on a pickaxe. "Do you remember that watch my father gave you as a wedding present?", Hans nodded and took it out of his waistcoat pocket. "Put it in the drawer", Matilda commanded "and your reading glasses". Hans put the items in the drawer. "Put on your gear and meet me out front". Hans put on his boiler suit, hat and boots and headed out. He was met by Matilda and Farmer Hogg who was pushing a wheel barrow. "Upt yonder fell", said Farmer Hogg, Hans looked blankly. Farmer Hogg muttered something under his breath and passed a scrap of paper with a hastily drawn map.

 

As they neared the top of the hill, Matilda brought out a compass and started wandering in circles. Suddenly the compass needle twitched and Matilda smiled. She cleared off the turf and almost immediately hit rock. She donned her safety glasses and raised the pick, thud, thud, thud, sparks, "bingo!" cried Matilda. The ore was shovelled into the barrow and wheeled down the hill to C.Defoe's builder's yard.

 

Matilda asked Mr Defoe for 4 diametrically magnetised disk magnets and the Golem smashed up the ore and squashed it into a disk under great heat and pressure. "I'll plate them and drop them around in the morning" said Mr Defoe. The next morning the magnets were delivered with instructions to take care not to trap their fingers between two magnets. The diametrically magnetised magnets ensured that Hans and Matilda would remain facing in the right direction.

Diametrically Magnetised Magnets

 

Magnet Holders

The initial thought was that the magnets could be attached to the mechanism using Sugru, however Matilda realised that this was a rubber compound and would cause friction.

image

There was a nylon bar that could be machined for a housing but that would be problematic to glue to the base / magnets. So a magnet housing was designed for 3D printing that could be clipped/glued onto the mechanism, ABS rubbing against the wood would run quite smoothly.

Hans and Matilda's platforms were carefully milled by hand so that magnets could be added to those too.

The magnets were test fitted in preparation for a full system test.

Thanks to Eric Styles from First4Magnets for advice on the right type and strength of magnet.

    There was an issue over the weekend, which I have confirmed has been resolved.

    Looks like a great solution ....

    On minor problem is that there are no images ...just the name of the image and even when you click on it ...nothing.

    Mark,

     

    if you refer to the original post there are lot of images... Maybe you (and someone other) didn't see the images. Maybe this depends on a problem that I was notified by the E14 tech support of a server that for a certain period today (4-5 hrs ago) was down? I contacted them as in China it was impossible to see some posts. I suggest that you (and atclark too) try to clear your local cache, I had to do so.

    The server that I was connecting to today was showing "Under Maintenance".

     

    I'll try the cache but since I hadn't loaded these before, I'm failing to see why clearing the chache should change it.

    If anything I would expect all the posts to exhibit the same  ...no images.

    I'm not sure a cache clear will help as I tried to see Hercules TMS570LC43x LaunchPad: Web Server Example and Lightweight IP and had the same problem despite it being the first time I've accessed it

    Thanks Dave.

    I've just gone back and cleared the cache, but only 1 in 5 pics are visible.
