• Cortana Data Chip and Display Stand

    I get asked to make more cortana chips from time to time, but the partnership that allowed me sell resin casted props is long over. I have been wanting to redesign as a display piece using a more modern neopixel lighting for the animations.

  • Upgraded Boba Fett Chest Displays

    Dec 2020 brought new episodes of the Mandalorian which blessed fans with the reappearance of Boba Fett and his faithful armor.  The chest display refresh gets me excited.  Instead of a blocky bargraph lightshow, we get a fully animated larson scanner!  Remember larson scanners? Classic sci-fi light animation that sweeps back and forth, night rider, bsg cylons, etc. My previous boba fett chest display circuit is not wired for a fully animated bargraph.  The ESB and ROTJ style animations both used 5 animated blocks above the character displays.  So I designed the bargraph to be run on 6 wires.  Five control wires from the chip and one common for ground.…

  • DIY Records for the Fisher Price Music Box Record Player

    I did a lot of research in April 2019 to make my own fisher price record of Baby Shark. Using the research from fred27 and improved upon by Tycho. I created my own method using excel to compose a song and OpenSCAD to generate the record 3d object. Before we get into that, some history. What is the Fisher Price Music Box Record Player? It is a toy record player sold in the 1970s and 1980s that plays plastic records without batteries. The songs are actually encoded on the records and the mechanism is wind up. So if you have a smarty pants kid they could observe the record player…

  • Making a mount for the Wyze Doorbell Camera

    I need a slightly different mount than the default plate included with my smart doorbell. Something to conform to the molding around my door and mate with the doorbell itself. 3D printing will do the job well. To make a 3D print that perfectly mates with something requires specific measurements. Typically, you need the item in hand and you measure with a digital caliper and then gives those dimensions to your CAD drawing. The Wyze Doorbell Camera is a already a great product from a great company, but it doesn’t ship for 3 months. Time to do a little reverse engineering and create a configurable SCAD script. I can create…

  • Game Cabinet Lighting with Neopixels

    I put together some ikea cube shelving and wanted a place to keep my game consoles while also displaying them. I started with 3d printing some vertical stands for the PS4 and WiiU along with some controller hangers and riser shelves. I then added puck lights to the surrounding shelves, but wanted special lighting for the game shelves. Using some spare puck lights, neopixel rings, and a trinket I created some smart puck lighting that responds to which game system is powered. Power up the PS4 and the shelves are bathed in blue light. Power up the WiiU and the shelves turn cyan. Power both, and get both blue and…

  • Changing Win 10 Application Icons

    In all previous revisions of windows, you could simply right click on any shortcut and change the icon as you please. Windows 10 still allows you to do this, but applications installed from the Windows Store are missing this ability. Unlike normal shortcuts, windows 10 applications do not have the option to change icons. Right click one and all you can do is visit App Settings or Rate and Review. You will not find Shortcut Properties and no way to Change Icon. You are the mercy of the developer to set the app icon (the worst feature on smartphones). If you drag a win10 store app, such as Calculator, to…

  • Prusa MK3S ~ Stop Button

    This was a one day build. I leave my printer running unattended and I know that others in my home would have trouble finding the reset button or off switch if/when something went wrong. Solution, add a big friendly stop button. I have built several arcade machines over the years, so I had plenty of control panel buttons. This is a 46mm 12V red button. I pulled apart the switch and swapped the built in resistor to be 100 ohms, so I could run from 5V. Prusa’s 3D printers are open source. Even better, they design their 3D printed parts using openscad. My favorite 3D CAD program. https://github.com/prusa3d/Original-Prusa-i3/tree/MK3S I grabbed…

  • Portable Solder Iron

    On a whim, I purchased a $20 USB Solder Iron from Aliexpress to play with. After playing with it using an old phone charger, I saw a video on Adam Savage’s Tested channel and got inspired. Drill Batteries as the power source. What a great idea! I have lots of those and always keep a few charged up and ready for projects. However, finding a drill battery adapter for my Black and Decker 20V set was a challenge. It’s all discontinued. Black and Decker only sell new bluetooth batteries with USB ports built in. No adapters to be found. Searching for a solution, I found forum posts saying that black…
