These have been kicking around for a while now but a friend just discovered them so I made her one for her birthday. This one uses a variant of the the living hinge design I saw on the MAKE blog. It uses a standard size servo, I removed the controller board, patched directly in to the motor and modified the servo for continuous rotation. It is powered by 3x AA batteries so it should last a while, which is convenient because I got too excited and glued the box shut before I figured out how I was going to change them. If I make another I would use magnets to hold the lid firmly closed until the arm comes out. (svg here)

Now available for sale, a little bit smaller than this one but functionally and aesthetically the same.
This kit can be purchased through my shop here
Northants Board Game convention is right around the corner and I'm exhibiting this year so I decided I needed a better business card holder to dish out my little business tchotchke. I found a file for a mimic box that I liked and modified it to come up with this little cutie. He's a very happy chappy, just be careful of your fingers when you're taking a card.
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...
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...
