970 mV under load today. I may have not let it recover after the short mA test....

Built November 27, 2014 - start voltage 970 mV - there is a lot of room in the copper pipe, so jiggling the mag strip could increase the
voltage up to over 1100 mV and occasionally I would have to do this to get max brightness. This was the watery electrolyte mix...
December 01, 2014 - 4 days after build, the mag adjustments had opened up one end and had to add water and reseal it.
December 07, 2014 - 13 days after build - had the same problem... took the mag strip out, added a pinch of Epsom, then put the
mag strip back in, added 5 mL of water, then sealed it.  It's showing around 900 mV, but can be jiggled to get over 1100 mV.
Conclusion: pack a dryer electrolyte to reduce maintenance... I'll do something drastic if I have to maintain this cell again in less than
a week from now...

Update on f149 "hotdog" chart..interesting saw tooth

Looks excellent. Next time, please, upload pics with 800x600 resolution at least or if you want with higher resolution and I can fix it from my side. I need to see in more detail.


Now, what is the load? and in the end of the graph I see the cell is dying. It is also getting dry??? If not, add more Epson salt solution and FC62 (zap) until smokes and all vapor is gone and amperage is around 10 mA. Let it dry completely and put on graph with a 100 ohm resistor again and let's see the curve.


Please.


Thank you.

load is a white LED of now but the saw tooth pattern is so different that I'm going to let it run til it reaches 0v or buffer runs out.
this was activated is epson and 30v dc sizzle, but too long..like 20 minutes at least each cell...


I updated the graph pic to the resolution asked for. I
would have to scrounge and hope to find a 100 ohm resister.
Ill have to decide weather to do that or graph my alum cell on the oscillator and if i do the alum should   add alum and sizzle again, just alum, epsom, just water?


Is the 100 ohm for the base line measurement or does it have a affect on the cell(s)  (conditioning??)

Thanks for updating the picture. The saw tooth is interesting indeed. 20 minutes is way too long. Please, send me a very close up picture of the cell. If possible make a video showing the zapping in process so that I can tell you what is going wrong.


The zapping with Alum is a totally different thing. For now I want to focus on F149 only. Too many variables to go through.The epson solution is to be used with the zapping only to start the process. Once the cell is under load and dead you should use the Epson solution (a few drops) to "reactivate" the cell and measure the load graph again.
