• 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. Old project thread: https://www.405th.com/forums/threads/keep-your-head-down-theres-two-of-us-in-here-now.27623/ Kits for sale: https://www.etsy.com/shop/WestabyElectronics Goals: No battery, the base is powered by a usb cable The base houses the electronics, the data chip only contains the USB connector and neopixel. Make closer to actual size. The previous ones were around 200% to make easier to handle by gloved hands while cosplaying.

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.

  • 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…
