Looks like this one nearly escaped the write up. Tree asked if it was possible to make a rubbing plate, 30 minutes later I guess the answer is yes. I'm now interested to see what Tree wants to use this technique for.
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...
The laser upgrade went remarkably smoothly and the laser cutter was functional but there were a few minor changes and improvements that needed to be done. Fixing the screen image Image flipped on the controller The first and most noticeable tweak for my new Ruida system was to fix the screen display. Most of my cuts are symmetrical so it was a day or two before I noticed that the image on the screen was mirrored. The laser cutter was cutting the correct way so I knew this had to be a simple setting on the controller. In the menu system is an option called 'Screen Origin' we have to set this to 'Top Right' so that the controller knows it's cutting from the same corner as the laser. Screen origin setting Screen Origin should be set to top right Image corrected on the controller Wiring in the water protection The additional wire patched into the WP line on the PSU The lid switch and the water flow detection were already wired direct...
Last summer, I had the privilege of creating a puzzle box for Chris Ramsay , the Canadian Magician and Youtube Puzzler (Not the English comedian Chris Ramsey ). Like most projects of this nature I failed to take enough photos, I rushed to complete it in a good time and I didn't even write about it here. Thanks to some very keen collectors, I have an opportunity to rebuild the box this summer. This time around I am going to write about it, documenting the design choices and code that goes into such a creation. I've even found time to list it on my puzzle website should anyone be interesting in purchasing their own copy. https://www.donteatpuzzles.com/nikolai The project was delivered in July 2024 and was filmed almost immediately by Chris and his team. I think it's fair to say that he loved it. Seeing all of my efforts being appreciated in this was is rather magical. I should just take this opportunity to thank everyone who supported me in making this, whether it was playte...
