Car Shells 2

-

The remote car cakes have a layer of plastic between the cake and the electronics. This needs to be shaped to fit the wheels and provide enough space for actual cake to go onto the car. The vacuum former is the perfect tool for this. I started by taking a mould of an actual toy car about the right size, this ended up being a one shot deal as the toy car melted on the second pull. 


At this point I had a sheet of plastic in roughly the right shape and a strong desire not to mess up a second time so I scrabbled around the garage to see what my options were. I found a bag of plaster of paris and decide that casting the mould was a sensible way forward.


The plaster of paris was cast, the kitchen was turned upside down, nearly every available surface turned into useful space full of junk, at least I had a few hours to tidy things up again. It was all a bit impromptu but good fun. The plaster of paris former was cut into separate parts for the cake. The middle section will become a mould for the cake part of the car, the nose and bonnet will house the electronics.


The plaster of paris parts were shaped, padded and mounted upon a base to hold them in the right places. The wheel arches were built up to allow ample room for the wheels. This new mould served well for the first half dozen cars, it was a bit of a struggle to remove the mould after it was formed and it started to show signs of wear which led to a mould rethink but that's for another day.

Wiring the Ruida Controller

The RDC6442G controller from Ruida This is going to be quite an image heavy post describing the rewiring needed to convert between the Leetro controller and the Ruida controller. It is also pretty straight forward on the old Just Add Sharks laser cutters because all of the wires are clearly labelled. The controller was prepared in the previous step in order to make this conversion process as smooth as possible. The Leetro (Pad03) panel on the left and the Ruida panel on the right The view from inside the laser looking up at the control panel The control panel is an easy place to start, both panels have just a single cable that runs down to the controller, both panels are a very similar size, with the Ruida panel being slightly smaller underneath so it will fit in the hole left behind easily. The Pad03 panel clips into place so you'll need to reach up inside the machine to work the clips loose. The cable runs down the inside of the laser and is cable tied onto mounti...

Laser Cut Cryptex

-
Image
This is my laser cut cryptex. It features 28 different characters and 9 rings, giving a total possible 10.5 Trillion different combinations. I took a bit of time developing the design so that I could add some nice features. This cryptex file is laid out so that you can have any number of rings in your own design. The best feature is that the codeword is changeable, each locking ring has an outer letter ring that can be placed in any one of the 28 different positions. Once the rings are back in place the ring locking bars can added and they prevent the rings from being modified until the box is open again. It's a bit hard to explain so I made a video showing how it all work ( svg here ) It took a long time to assemble this so I lived with my initial design choices but if I were to remake it I would adjust the file to make the ring locking bars out of 6mm ply and maybe put some blind holes onto the code rings to prevent the code being brute forced.

Rainbow Puzzle Box

Image
This is a binary sequence puzzle box built from 3mm birch plywood, it uses a Gray code pattern to ultimately align all the dials into a rainbow pattern before the lid can be removed. It's actually a redesign of a puzzle inside Loki's box of Tricks  because I thought it would make a cool stand alone puzzle box. The files are available for sale in my Etsy store . ( svg here ) The puzzle consists of five interlocking disks that can only rotate when the disks either side of it are in the correct position to allow it. The large wheel in the middle and the disks on the underside of the lid further restrict the rotation of the disks. The large wheel must be pointed to the disk that is being rotated and the large wheel is in turn restricted from pointing to the smaller disks depending on alignment. Once all the disks are aligned into the full rainbow the large wheel is completely free to rotate and can be turned to the edge of the box and allows the lid to be removed. There is a very ...
