Dyson Cyclone Mod for Roomba S9

Cyclone Filtration in Roomba S9 Base Station Possible? Yes Chance of Failure? Medium STLs and Fusion 360 are linked below. Project Intro: Objective: Design and 3D print a replacement to the classic iRobot Roomba Station Bags. Never before have I designed a cyclone filtration solution, which required a lot of research.  Design: Cyclone Testing: Surprisingly, a nearly random cyclone shape worked very well in small-scale tests. Time to scale up! This time, we are testing varying particle sizes and different aperture sizes. Again, very surprised by how well it worked! I connected these to my Dyson V12 for consistent, reliable suction in particle testing.  After 40+ hours of printing and trial-and-error testing, I was ready to begin the final design as the first proof of concept. Findings: There is a scientific method to approaching this, and a complete understanding of several external factors would need to be known to render the best possible cyclone. Factors such as suction power and par

This tutorial may be exciting, here is the science: https://blog.hobbytimewith.me/2022/01/true-brightness-of-tritium-vials.html Looking to Buy Tritium?  https://blog.hobbytimewith.me/2021/11/tritium-buying-guide.html Requirements for Great Photos: Google Pixel 3 or above Passion for Tritium Can you accomplish these results w/o a Google Pixel? Yes, however, you need to play w/ your exposure settings. Demo: Take into Consideration: Lighting Movement Subject Brightness Point and Shoot vs w/ Post Processing: Most shots of tritium with this method are quite good and don't require ant postprocessing. There are circumstances that enhancements to the photos will result in a more desirable look. How to take the photo: line up your scene like this. Does it need to have all this fancy stuff?

True Brightness of Tritium Vials

How Bright Are Tritium Vials? Describing the brightness of tritium can be difficult. People observe the luminescence differently and have differing opinions comparatively. So how can I  genuinely   share the luminosity of tritium vials and rank them?  Below I will showcase my findings using different techniques to put things into perspective. First things first, let's recognize the charting available today; maybe you have seen these or some variation of them:   These images are well over 10 years old and have several variants, some poorly photoshopped floating around. Let's make it our objective to reinvent this chart. Essential to take note, the charts above mostly agree on one thing, the ranking of 'output/yield' compared to each other by color. Spoil Warning , my results don't align with the common consensus listed above.  Take Amazing Photos of Tritium: https://blog.hobbytimewith.me/2022/08/how-to-take-great-photos-of-tritium-and.html Looking to

Silent Ender 3D Printer

Silent Ender 3 w/ Noctua Fans Less a DIY tutorial and more a parts list showcasing the success of this project. Problem I was over the moon when I purchased my first 3D printer. It wasn't long before I found myself upgrading one piece at a time. In early 2020, my basement, where my 3D printer lived, became my Work From Home (WFH) office. My 3D printer was too noisy to be running in the new office.  I still had the original V1 motherboard and fans supplied with the original Ender 3 V1. If you own this printer, you will understand that it basically sounds like a jet engine at all times. This wouldn't do if I were to have it running while I was working from home. Solution I have always been a big fan (pun intended) of Noctua fans. A quick Google search yields many attempts integrating Noctua fins into the Ender 3 with success.  Short parts list: 4x DC to DC buck converter: Amazon 3x 40 MM Noctua Fans: Amazon 1x 60 MM Noctua Fan: Amazon 1x Ender 3 Mainboard (silent) : Amazon Duct

Tritium Buying Guide

How to get your hands on some tritium? This guide will provide resources and what to look for when purchasing tritium. With the shipping disruptions of 2020, prices are all out of wack and should normalize.  Note: This guide will not cover the legal aspect as each country has its own laws and regulations. To learn more about the luminosity and spectral intensity of tritium vials, read my post here:  True Brightness of Tritium Vials   Spoiler: Tritium Safety Isotopes should be treated with respect, not only for the safety of yourself but also for the safety of others. The average amount of tritium inside a tritium vial has been observed as such: 3mm x 22.5mm tritium vial is roughly 0.1 curies (3.7 GBq) 5mm x 150mm tritium vial is approximately 1.8 curies (66.6 GBq) Is That Dangerous? It would be inappropriate to say anything other than 'Yes'; however, the risk is highly negligible. The EPA  touches on how tritium can enter and be processed through your body. Tritium is a low-ene
