Springs are a big deal. Did you see the ones Imalent used on their DT70 and DT35? Instead of coil springs they used disc springs which only flex a tiny bit, less than 1 mm. So obviously they want you to use the Imalent batteries. Even then, some of the batteries will lose contact. Springs have to be done propery. Lol
I do know a lot about springs from designing suspension systems on race cars. Some of that knowledge transfers to flashlights like preload and usable travel, etcā¦ I just try to state facts without any emotion, but maybe it seemed I was āoverzealousā maybe? Iām sorry, Iāll try to tone it down. :sunglasses:
Sir Jason of Houstington, I salute your efforts to keep old springs lively and supple. Itās quite unfortunate when springs enter old age and canāt perform like they used toā¦
Itās just ā¦ I think the Q8 team has it covered. And as we wait for that to get worked out, why not play? The Q8 may not be shipping yet, but we can still āshipā other fun thingsā¦ so I used, as examples, whatever recent posts stood out. Not specifically trying to pick on anyone, but if it came off that way please let me know so I can be more careful.
On the bright side, youāve officially levelled up to One Millihelen. Not many people have had a ship launched in their honor.
Because we are already a bit offtopic and i have to find something to do until the Q8 is out i want to ask if someone had experience with one of this UV leds?
I want to build a light with an MC-E led but the MELD-X RGBW (uv) flashlight driver has a 5 channel for a uv led so i want to get a nice strong 385nm led (for glue curing). If there is something better or stronger out there that did not cost 3times the money i am open for suggestions.
Hereās a topic worth discussing. Weāve covered the light, weāve covered the batteries, what about a good charger that has 4 slots and can do 1A each (4A total).
I was looking for one that can do 4 x 26650 at 1A each. I know xtar has a dragon plus that can do it, but itās $90. There are the 4 and 8 bay Gyrfalcons that can do it at $30 and $55, but they are kind of tricky to use. Thatās all I could find. Any other suggestions?
A $15 imax B6 will charge at up to 5A and works great, although the cell holder to go with it costs another $3 or so. Still less then $20 for a charger capable of charging them at 1.25A each if budget is the goal.
Otherwise I am not aware of any pre-made chargers that would work for cheap.
It is the most common and most used hobby charger ever if I had to guess. It is just not setup with a cell holder, so you would have to get that separately.
Cheap, good, easy. Pick 2.
This is cheap and good but takes a bit more work to use. If you want it good and easy you will have to pay for that convenience.
On the plus side it can charge almost anything, I have used it to charge cell phone batteries, car batteries, Drill battery packs and UPS backup batteries among other things.
That thread is talking about balance charging the cells, this is not needed if you charge them in parallel and parallel is much faster then balance charging in series.
Simply get a cell holder that is wired in parallel, hook it up and set the current and let it run. No need to bother with anything else. I charge 14 cells at a time like this and they come out perfectly balanced everytime.
You can find them on ebay or aliexpress pre-wired or bare. I just got bares ones and wired them up myself but if you canāt solder then you can get the pre-wired ones. The wires are usually a bit thin though.
