Mod: Zoomie with MT-G2

[pilotdog68]

Wow, I’ve never seen so much rust

[MountainKing]

Very nice stuff. Someday I swear I will start buying soldering tools and TRY to start modding.

Great picture! Is it a coal mine? So those carts will never come out of there anymore!

[MountainKing]

How do you guys solder those 7135 chips to the board? Is it complicated?

Btw, awesome pic!

great picture!

Thanks!

@totilde

I´ve been checking your flickr yesterday. It seems like you like abandoned places, don’t you?

I do. My main interest is climbing but I do have a soft spot for abandoned places, especially old abandoned mines.

It was a mine for iron ore. Those carts will never move again… unless an unlucky explorer would happen to trip over this nearby pile perhaps:

In my case I use hot air soldering to solder on all chips (MCU, resistors, capacitors) on to the board. If you want to solder chips on top of existing chips you need to “stack” them. I’ve done stacking, but I hate it. In all my later builds I use my own driver designs so I do not have to stack. It’s not complicated but I find it frustrating those times it doesn’t go smoothly. Here are some tips on stacking:

stacking AMC 7135 - impossible?

hey guys! I tried to stack some 7135… and failed like hell! the solder blob jumped everywhere and did bridge everything… but NOT the wanted 2 pins which has been aligned to be soldered! I have a new soldering iron (switchable 15/30 W) and use some Flux-filled solder; is that the problem? also the solder “climbs” from the tip to the thicker part of the soldering iron?? I am frustrated

HOW LONG DOES IT TAKE TO BE ABLE TO STACK 7135 CHIPS?I DID IT :stacked 4 each 7135's

EDIT:I changed the tittle as the chips stacking is my major obstacle; I know I have brought this up in the past, and you all have encouraged me to continue to try, so now I ha e been trying over a year bought a better soldering iron, helping hand s with magnifying glass tools, tools and more tools and I still can’t stack a 7135 I just got 60 ,380 mAH chips this Friday and 6 105c 200 mah driver I am down to 0 driver and 3 chips now as I have fried all of them unless it’s braiding springs and moun…

Don’t bother trying without flux.

Thanks man. I’ll keep this in my subscriptions for the time I actually will get my hands dirty! Gonna watch the 2 vids at home. Should be very instructive.

Hi Mike C. Does 18650 batteries also fit loose in the tube? Does it come with a 18650 adapter to give a tight fit? Thanks!

Those zoomies came with an adapter tube, so fitting was fine.

Thanks, appreciated. Will get one to play with then…

Holy @#$%!! I’d be sweating if I had to wade/walk next to that!

Awesome pictures. Mines are dangerous places, stay safe!

Thanks I try to be as safe as possible, gotta be on your toes in these places.

Hi Mike

I bought one of these lights some time ago from Fasttech… I really liked it, but I could not get the switch disassembled for modding. I had to eventually break it apart and kind of messed up the light. I’m not sure if these lights come with different switch assemblies? Can you maybe take a photo or 2 of your switch assembly and if possible show it dissembled? I’ve already discarded my light, it was kind of useless after messing up the switch assembly, but, I’d like to give the light another go if I can sort out the switch issue. I think it has potential…

Thanks!

[Mike_C]

Will do. I’m at work right now (10am) so I’ll do this tonight. There could be differences with the switch assemblies between the FastTech and Banggood versions also, as there are quite a few differences. I’ll take a few photos of ’em both.

i have a couple of those zoomies as well, might have bought them from banggood, not sure. one has a hollow pill.
great mod anyway, and it looks like a great driver!
looked at several of your albums at flickr, quite fascinating with the old and abandoned places there!

Tackar!

I haven’t worked on these kind of lights much lately, my ATtiny84 projects have taken all “light” time, but I have a new design laying around waiting for it’s turn.
