I’m thinking that the pencil lead trick for the Nanjg drivers would be an easy way to test out having 5 or 7 7135’s enabled and whether one likes it or not. Certainly easier than soldering and un-soldering things (for me adding a solder blob is easy and quick but removing it not nearly the same).

I have used the pencil lead trick. it’s amazing. Hopefully someone will show us the path for the lead in time, thanks.

Are the solder points on the extra 7135’s on one of the power legs, or on the PWM leg from the MCU?

If it’s on a power leg, I’m sure pencil lead won’t work for passing 350mA. It might work for passing the PWM signal, but I’m not sure.

You could probably also try taping a small square of aluminum foil over the jumpers for the extra 7135’s. Just be careful not to let it touch other contacts.

Is it the case that changing the color to a half mixed tint, that all AMCs run without PWM or on full power?
So the latern would be double bright as in extreme cold / hot color temperature?

Mixed tint runs each channel at about half power. Power level is kept approximately constant across the tint range. The intent is to not see a brightness change.

The AMC’s run on full power without PWM at the extreme warm or cool tints.

Candle mode runs the lantern with the last selected output level and tint right?

That sounds right as far as I understand what TK has said before. It sounds like that includes if it is in auto-tint mode:

Yes, actually. I adjusted candle mode specifically for this light… and also have been putting it on a table full of actual candles for comparison. It’s not perfect, but it’s not bad either. The overall brightness pattern is random, but it looks like this on a graph: [image] I also gave it a mode where it can change tint automatically with brightness, which affects all other modes. When used in candle mode, it should give at least a subtle coloration effect, but it’s not very noticeable. Basi…

By the way, you can adjust brightness while in candle mode. I’m not sure if you can adjust tint, or if you would need to turn off candle mode, adjust tint, then start candle mode again.

Neat photo, Den. Did your power go out at 6:47 PM?

Is that a double-sided clock? I’ve often thought about getting one of those!

it went our around 6:30 roughly. Yep that is a double-sided replica of the clock from Grand Central Terminal in NY.

I am interested in one without batteries.

Taping down foil or a thin wire would work just for testing out how one likes it. For a permanent solution a solder blob would be in order but I guess conductive epoxy would also do the trick. Personally I would use solder since it’s not that hard to do.

Please put me down for 1 more, for a total of 2.

That actually brings you to 3. I added you anyway since more is better than less

[Stereodude]

Please add me for 5 more bringing me to a total of 7.

Thank you.

I wonder…wouldn’t it make sense to run the candle on the warmest tint regardless of output?

Done

[amishbill]

I believe I’m in for 2 right now. Please take me to a total of 5.

[radicalphoton]

I’m on the list for one, please add another one for a total of 2. Thanks!

So are “flat” top NCR18650GA going to work without modification in the LT1? They’re not really flat and do have a slightly raised center positive contact unlike most other flat tops though not to the magnitude of a button top.

[DBSAR]

I’m always doing long term testing. After the power outage a few nights back, the test unit after running for 3+ hours on maximum, next day the cells were at 3.89 volts. it took only 5 and half hours of sunlight to fully recharge them with the Eceen charger. Again reinforcing the viability of the LT1 with a good solar charger being an indefinite light source for years off the grid.

If the metal contact of the positive end of the battery top sticks out past the insulation of the battery, it will work.

[rollawaythedew]

Count me in for 3. Thanks

[westermac]

Please put me down for 2 additional lanterns, for a total of 3. I’m currently #2224 on the list.

Thank you!

[figment]

Please put me down for three more, for a total of five.

I’m already on the list for two, 1938 and 1939.

Thanks!

@SIGShooter

To me today seems like a slow day in terms of adds to the interest list but there’s 17 to this point, and that’s the 9th most in a day since I starting tracking things.

For the week:
Monday - 139
Tuesday - 41
Wednesday - 17

Total of 197 just for the first 3 days of this week

Total of 2,262 for active members.

Just wondering if I got added to the list. I think I requested 2 yesterday but haven’t seen my name added to the list.
Thanks
