• 3D Printer Music

    I was working on a custom script to automate knocking parts off the print bed into a tray so I could easier manage remote prints when I stumbled on the musical features of g-code. Here are my references: Teach your 3D Printer to Sing and Dance Online MIDI Editor .midi file to G-code Converter See it in Action! Here is my g-code. Copy to the end of your Printer Settings > Custom G-code > End G-code in your slicer.

  • Solder Fume Extractor

    Back in 2018 when my kid was born, I got serious about air purifiers and fume extractors in my workshop. I designed my fume extractor using spare parts and a cheap mini filter meant for a smokeless ashtray. It is finally time for an update. Here is my 2022 fume extractor!

  • Mk2 Boba Fett Range Finder

    The Boba Fett Range Finder prop with lights comes in two varieties. Switched on by a microswitch in the helmet stalk, or a tilt sensor in the range finder. Sales: https://www.etsy.com/shop/WestabyElectronics My initial design used the latter. For shipping reasons, depending on your country, a ball or mercury tilt sensor was included with the Mk1 Range Finder. However, I do not like either of these options. The ball can get stuck, and mercury has shipping restrictions.

  • 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…
