I instantly thought of the shorting aspect of using metal calipers also when I saw the picture, but I just figured that the set up seen was just for the sake of the photo. Metal calipers could be used with an insulating spacer and then just subtract the thickness of the insulator from the measurement. The insulator could be as simple as a piece of card stock.
I prepared the cheat sheet in the Hungarian language. This is not a small but quite understandable thing I think. Anyone who needs this can download it on THISLINK.
Wow all this talk about my picture using metal calipers. I’ll admit I almost measured the cell bare but then realized why that would be bad and put a small piece of paper on one side. The picture you see is after measurement with the caliper resting on the table (not reaching the positive terminal)
Apart from the safety issues, a fat spark could ruin the precision ground surface of the callipers, spoiling them for precision use. Put a piece of e.g Kapton tape, or ordinary Sellotape on one end first.
And do treat car batteries with respect, inside they contain an explosive atmosphere of hydrogen and oxygen. If the battery has been over-charged and “boiled” the electrolyte (acid) heavily, there may little (but highly concentrated) acid left, and most of the volume filled with explosive gas. Abuse one with e.g. a short and if an internal spark happens e.g. when a bit of the lead inside melts, or an external spark ignites lingering hydrogen, kaboom ! A substantial explosion, happened to a neighbour, car bonnet blown off and conc. sulphuric acid sprayed everywhere. Before attaching leads, ventilate thoroughly in case there is any hydrogen lingering around.
Modern “sealed” ones are safer, they have a catalyst inside to recombine the H2 and O2 to water, but it is a slow process which does not keep up with heavy charging currents, e.g. after a battery has run low, then been recharged on a drive by the full output of the alternator.
Hydrogen has one of the widest range of flammability limits, so is an extremely dangerous gas to have lingering around. And when generated by electrolysis inside a lead-acid battery the perfect explosive mixture is produced.
Anyone remember where to find the post where a 3d printed lantern diffuser was featured, with a link to the program? A friend of mine just got a printer today and I can’t seem to find the post with thread searches.

BG canceled my Q8 order dating back to 9/7!!!!
And no back payment on PP… so they still have my money.
Advice?
PS: i just placed again an order for the Q8 – my code still works.
I’m still down $40.
BG paid back the money on PP so all it fine somehow.
The last Q8 i ordered is already shipped. The first is on it’s way.
Back on track.
Banggood is straight as a die in my experience.
I have cancelled orders there for a PayPal refund and seen it done within hours. Glad yours went through. Holidays maybe ? I could mention “first world problems and impatience” but I won’t
Unfortunately it’s Saturday and the post office is closed… It will have to wait till Monday… Best case scenario is it got put into the wrong box and an honest neighbor will bring it by. We have a the multi box for the neighborhood setup with 2 large boxes for packages.

That’s not exactly the whole story. We as USPS customers can’t see where the delivery was made, but the office can, at least in some cases. This has happened to me as well, says delivered but not to me.
When I went to the local office and explained the situation, a guy in the side room looked it up in the computer. Their GPS system showed the location of where the package was scanned “delivered”. It was accurate enough to show that it had been delivered to a mailbox in the other cluster of mailboxes in my townhouse complex. There are two clusters of boxes in the complex, and mine is on the east side, while the delivery was at the west side. So I guess he made a note for the carrier and it was rectified the next day.
All that just to say, that it does show where in some cases, but you’ll have to ask the local office.
The simplicity makes it an awsome idea.
I love extra features we have these days but, when ity becomes so complex you need a tutorial.... that's a bit much.

thanks the miller, i just ordered the ali plastic calipers.

Seems like you can use wax paper / baking paper as insulator too. I use it a lot in my micro to collect the fat and gravy when baking raw food.
GREAT! Even more tables.
Love it
Dale out of all of your chargers, which is your go to? Or does it change depending on the cell?

Thanks but it doesn’t appear to be the same thing. I am not only not a flashlight guru I not very techy either.

It should be very close
The Joechina cheat sheet is designed to be printed and folded and kept in the light the other is designed for a A4 paper.

Argh… screwed by the post office… My lights show delivered and I saw the postman drive by so they should have been in the mailbox. Nothing. Nada.

I have run into this three times thru the years. Thankfully each package was delivered to an honest person all three times & I got them the next day.
Delivery confirmation is worthless in cases like this. It only shows the package was scanned & delivered…. not where.
Good luck……

Somewhere in CA there’s a USPS postman with the brightest light in town…
I’m sure you’ll get it sorted…
Unfortunately it’s Saturday and the post office is closed… It will have to wait till Monday… Best case scenario is it got put into the wrong box and an honest neighbor will bring it by. We have a the multi box for the neighborhood setup with 2 large boxes for packages.

There was a pack of batteries with it. Perhaps I’ll look for the ultra bright light in the neighborhood tonight.
“Facts don’t care about your feelings.”
~Ben Shapiro
Hopefully so then… Not a bad idea about looking for a bright light either.

I wish the only drama ever in anyone’s life would be to nervously expect a Q8 that’s overdue.
