LaserSaber SJR vs Joule thief vs MT3608 vs qx5252
This shows a relative comparison of the 4 most popular circuits I run with my projects. The 4 have their own use cases and efficiency curves.
Given the new mA readings, I can now say the SJR is efficient at high voltages but comparable to the MT3608.
FULL Specs
- SJR V3.0 from LaserSaber - GU Ferrite Magnetic Core
- Joule thief configured from the same SJR GU core
- Boost converter used is the MT3608 found all over.
- qx5252 Chip as configured in common garden lights.

Various voltage comparisons and new resonance shifts observed.
Compared running LEDs on pure DC of the battery's.
Can conclude that the SJR does allow a wider voltage range to be used with usable light. Suitable for capacitor discharge scenarios. The feed back does also seem to extend the run time compared to a pure DC battery mode.
May attempt a comparison to regular buck/boost converters etc.

Do not try this at home. U must be experienced in cold and high voltage potentials. This will hurt if done in properly.
