My Wife has an amusing sense of humour too and after seeing the chew/write pencil she immediately asked if I could make her one of these. It took far longer to find the plain wooden pencils than to draw/make the item.
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
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
The time is 12:10 and 31 seconds Now that we finally moved house we have space for all the extra things. The new house has a large extension which allowed us to turn the old dining room into a bit of a games room. We're now the proud owners of a Stargate pinball machine which we love but it's very possible to loose track of time while we're playing. I decided that we needed a clock in the room and it would be cool if it was in keeping with the pinball theme. I dug out an old dot matrix display and a wemos D1 wifi controller so that it can retrieve the time from the internet without the need to set it up. The screen is an 8x32 red LED dot matrix , controlled by the MAX7219 chip. The display uses SPI to connect to a Wemos D1 microcontroller , this means there's only three data lines that need to be wired between the two devices. Power and Ground are also connected to the Wemos board which allows the whole thing to be powered from the USB connection, this is useful for pr
