I love it! You need a trash can right next to the table. I have a trash can about 15’ away, so I can do basketball shots into it, with my mistakes!
It really is a beautiful build and I know you will come back to show it off when it's done. It looks like you are doing well and as you say, learn from your mistakes, so it should be ab awesome light!
Thanks OL!
Trash can sure would be handy and throwing basketball shots to it would also cheer mind up 
Bugger. It comes back to the old saying that if something can go wrong it will. Tomorrow is always a new day that brings a clear head and with any luck a happier wife. To you as well have a happy new year and looking forward to the next chapter in this amazing lght. Cheers.
Great machining skills! How did you polish the parts?
Thanks! That saying seems to be very true. It’s a new day now with clear head and new plans for how to implant that driver ( happy wife also :).
Thanks!
I used 800&2000 sand papers. After that I used two types of waxes with leather to get finishing polish.
Parts that I made in lathe - I also polished in lathe.
Really nice work. George at Taskled makes very good drivers but it takes a lot of patience to cycle through 13 different programming modes. Nice that you can set low voltage warnings at different levels using different battery setups. Thank you for posting set backs as well as successes. That’s the way modding can be with a first time build. Looking forward to your results.
Thanks! Yea, those are really nice drivers. It makes light much much more usable. Set backs are my way of learning things :).
Great work man! That truly is mirror finish!
kahvitahra, that looks really sweet…. i wonder how does your bike look like….
Hehe, Thanks man! Currently I only own city bike, so nothing fancy there
Hi again!
So, I finished my battery pack this week. As I said earlier it’s powered by 4S2P 18650 3100mAh batteries.
Here’s parts that i worked with ( also some wires, heatclue & wood sticks between batteries )
After cluing and soldering batteries together, adding balance and power lead, this is how it looked like.
I was a little afraid of heating that shrink shock on top of that pack. I’m sure batteries heated over 100C while doing this. Those big shrink shocks ( with clue ) takes massive amount of heat and it takes some time to cool off. But “luckily” nothing exploded and I did get ROCK SOLID battery pack.
After it was completed I went to local store to find right size and cheap camera pouch on top of pack. That pouch has velcro strap also, so I can easily mount it to bicycle bar.
You are better to have a 4S protection board build-in the battery pack.
Not neccesary if you have balancing leads and hobby charger. Batteries are good enough to withstand small shorts. Only long lasting shorts can be a problem. If you are carefull enough this is not big issue either.
@kahvitahra, good pack! Only the main cable could be a bit thicker. I’m using latest Magichine extension cable cut on half.
How did you solder cables directly on batteries?
nice job on the battery pack and that wrap looks seriously thick! might be worth sealing the ends with some plastidip too, just in case you get caught out in a downpour.
I agree with Ledoman about the battery cable - use the thickest MS cable (the 1m extension cable is a good source) and keep it as short as possible to reduce voltage sag. Your’s will probably be more than ok though, it’s not the end of the world
About that protection. I had that pcb for 4s, but I left that out. With driver that cuts off low voltage and charging with hobby charger via balance leads I did not see point of putting that one in. I’m living on the edge!!
You guys are right about that cable. I’m not super happy with it ether. But I did not have better one right now. Next time I get thicker cable for sure. That cable is actually very short. I mount pack near the light, so no need for long cable. This is one of those things that I do differently next time.
I used 800 sand paper to grind ends of batteries. Then added drop of no-clean flux and heated some solder to each end of batteries. Then just soldered wires to these ends. Each solder was really solid and nothing in loose there.
I finished this light! Whoa, feels great after these little set backs. I actually had those drivers a while now. It taked like a week for those to arrive after ordering ( I’m very happy to purchase from george@taskled in future also ). Few days back I had time to continue with this project with new plans. I did some lathe work for that pill again. I noticed that the reason why I got previously that “leak”, what caused leds to shine while light was off, was that wires that I soldered to driver contacted pills body from other side. So, I increased diameter of hole in pill and now there is not any unwanted contacts.
I was so focused while doing this driver implant so I did not remember to take pictures of process. After all it went like I planned in first post expect that I soldered all wires to driver first. Then mounted driver and fastened it to head. Outside of head I contacted switch and battery wires to this cable that goes in head and sealed all individual contacts with heat shrink. Then sealed all these with shrink sock that included clue for getting it solid.
Here’s some pictures of completed light.
I’ll take some outdoor shots also this weekend. Let’s see how this lights up those snowy streets!
That is a work of art, very nicely done.
Glad you got the problems ironed out in the end, looks like it will be a blinder of a light. Looking forward to the beamshots for sure.
Thanks buddy!
I’m pretty happy on how it turn out in the end.
Now it’s snowing so can’t take those beamshots. Tomorrow should be clear sky luckily.
After your initial setback what an epic finish. Your workmanship is first class and no doubt the light output will also be just as orsm. Fantastic job.
Very nice, a beautiful light. You should post it over at MTBRforums in the DIY section.
