Reduce Variables and Automate Testing

Automated Cell Testing

Raspberry Pi Nuclear Battery



What variables are we tracking?

From here on, we will define results as their relation to a 'Cell Combo'.  A cell combo consists of the two variables we want to focus on changing while all others remain static. Below, we cover a more complete set of variables we want to monitor and manage, for the cell construction we will be representing the cell combo as the Tritium Cell ID and the Solar Cell ID.

Key attributes to measure the cell combo are:

  • Open circuit voltage
  • Current draw

Changing Variables:

Static or controlled Variables:

  • Resistor
  • Capacitor
  • Wire length and type
  • Ambient light
  • Local AC (noise)
  • ADC impedance
  • Relay inductance (noise) 
  • Raspberry Pi (noise)
  • Temperature of components 

How to capture?


Component choices

Components are chosen for their efficiency and consistency.

Tritium Buying Guide

How to get your hands on some tritium? This guide will provide resources and what to be on the lookout 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 extremely negligible. The EPA lightly touches on how tritium can enter and be processed through your bod

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

DIY Spectrometer

Tritium Vial DIY Spectrogram To make the best decisions regarding solar cells, understanding the emission of Tritium Vials is critical. A lab-grade spectrometer can cost $5k-$10k, a bit out of budget for this project. Instead, building a spectrometer isn't too terribly difficult. Consumer-grade tools are available that enable the home enthusiast to construct an estimated optical spectrometer that, for general purposes, can be used. The range of this DIY spectrometer is easily between 40nm to 700nm.  To learn more about the luminosity and spectral intensity of tritium vials, read my post here:  True Brightness of Tritium Vials   Spoiler: How to Build this Spectrometer? Credit, where credit is due, this 2016 project by Tony Butterfield,  is the root for this idea; the physical form was replicated to the best of my ability with some improvements.  The code was initially analyzed  and determined to be a guideline rather than a commitment .  The CMOS sensor and features in
