Project #13 Laser Cut Weaponry

-

Some of you may already be aware that I 'LARP' as one of my hobbies, it was even briefly mentioned on the Make magazine blog. There is a new game starting this year, Empire LRP, which promises to be one of the largest fest events ever seen in the UK with record numbers of pre books and untold numbers turning up on the gate. Anyway I digress, a new game means new weapons for my character. 

I had done a quick test with Plastazote before so I was aware that you could cut it with the laser but now I had the opportunity to make something I actually needed. I drew up some quick sketches for a shield and came up with this design, cutting each scale out individually is not something you would ever bother doing by hand so it fits a criteria of being unique. The shell logo identifies the group and the rest of the shield is a standard construction. (files lost)
13 projects/ 22 weeks



The scales were cut as wavy strips and then overlapped onto the front of the shield. I've done some scales before and I wish I'd remembered that as I think I prefer those. The principle is the same though, a row of scales is held together under the overlap so you can put in whole rows at once. The shell detail was cut from the sheet and then the remainder of the sheet used to align it onto the shield while gluing.

Being the first attempt I did this the hard way. The thin sheet of plastazote curls on the laser bed so I held it down with magnets, moving the magnets round to do each row of scales. Time is money though and a much better way would have been to place a 2mm sheet of laser mdf over the plastazote to weigh the whole thing down and then cut through the mdf and the scales. You'll end up with sheets of mdf scales that would find a home somewhere else (I already have a project in mind), it costs 90p for the sheet and easily saves an hour of messing around so worth it in the end.

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

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 ...
