I just measured and ran some calculations, battery tube to driver ring contact is approximately 208 mm^2. Assuming contact around the full perimeter. There will be bedding that happens, and making sure that the driver board is flat should certainly be done, but I agree with Tom, it should last a good long time unless you are mechanically locking out or swapping batteries multiple times per day.
Finally got it!
Getting more “messed up” in my opinion/personal experience with Postnord lately here in Sweden for the final delivery on gods from China.
Anyhow,
Very high finish, extremely happy with functionality and super a value for my money so just very pleased with it.
I would have ordered another right now, but currently out of stock but thanks Tom E for the heads up.
And once again,
BIG Kudoz to all involved with the project, and glad to read there where a few bucks over to some of you.
V1.1 had some life to it, can't recall details, but think it was a temporary release for the GT buck driver. So to avoid any confusion I bumped the rev number.
It's been common practice for me that if a release "leaves the building", then if in doubt, bump it out (up??). Out rhymes though
Looking to follow up on the status of my order. It has tracking from last month for the 22nd through 25th, and then nothing since then. The “expected” delivery date was over a week ago, according to their own site. Not sure what all information I need to provide to TM.
Found another use for the Q8: recharging solar Casio G-Shocks and Citizen Eco-Drive watches ridiculously fast! My solar Eco-Drive went from dead as a doornail to ticking normally in just a few seconds.
I had a bad one (flickered, then out, etc.) in here form a BLFer, and reflowed the parts, problems went away, but came back like weeks later - go figure. The smart guys (DEL, etc.) thought the thru holes were suspect, so they probably are. Seems to be the PCB board itself.
Now I'm using the 2X and 4X OSHPark boards as replacements. Also bought the qty 50 of the buttons from Banggood - seem to work well.
