Modding the Small Sun ZY-T20 - MT-Gangnam Style - Done - With Beam Shots

damn, that’s some amazing work for the materials on hand. I think it’s time to invest in a lathe… :slight_smile:

... keep up the crazy awesome mods... :)

I promised all the lathe guys here that I wouldn’t do that, Sealed.

If I had a place for one, the spare power in the electrical service box and the money, I would have a lathe, but I don't have any of the three.

That is very cool. I’m also a fan of these MT-G2’s. I really didn’t think I would be at first but they are growing on me.

I want to know when these sellers will wake up and start coming out with a for real and just for only MT-G2 driver. I think it's wayyy past time for that. Of course, they will probably make it only pushing 2.75 amps, if it's anything like they do with everything else.Tongue Out

It would be nice if they would. Right now the best driver I have found to run one is the driver in the Lustefire triple. It draws enough amps to pop the protection on two panasonic 3400’s. I have it in a Small Sun ZY-T08 and it rocks. Well over 3,000 lumens at start up.

I contacted Wallbuys to see if they will get some in. I’ll let you know if they do. It has to be filed down to fit but once it’s in it’s perfect. I wish it didn’t have the blinkies but beggars can’t be choosers.

+1

Depending on the light it comes from, stock they seems to do between 7-9 amps. And the current it does on high it will do nicely regulated, at least if you are using three cells.

There are already a bunch of drivers out that there that works quite nicely with an MT-G2..

Old-lumens don't need no stinkin' lathe...he is the original human lathe!

I only have one question: will there be a music video released alongside the review of the completed build?

9 amps?!!?

More photos in the OP

24 chips, should be about 9 amps

Where do I start? Just how much patience do you have? That heatsink itself, wow. The effort involved is incomprehendable to me. What an effort. I may have asked this before, how do you finish it of so its so round and even getting it so flat? Looks like you have found the answer to the shadowy ghosts as well. Good luck with the next stage. This is really amazing work.

I started out with the flat rectangles that were the result of splitting the pipe couplings and flattening them with a hammer and a block of wood. Then I traced out the circles, (2 on each rectangle). I cut them out with a pair of metal shears. First in squares, then cutting the corners and cutting again, till they are octagonal. Then I hammer them all flat again and coat one surface of each one with solder, by heating with a torch. Then I stack them up and use a pair of vise clamps to hold and squeeze, while heating them all together. That squeezes them tight when the solder melts. After cooling, I put the soldered mass into a vise and start smoothing off the octagon with files. Once I am fairly close, I use a dremel bit in my drill press and work it down till it fits. The final edge finish is with a dremel sanding drum in the drill press. It is not a perfect circle, no matter how hard I try, but it's close enough for horseshoes and hand grenades.

I’m stumped for words. A+ for effort and achievement. Thanks for sharing.

Cold! COLD???? It was 16 deg. F in Amarillo this morning.... 5" of snow on the ground and a 20 MPH wind out of the north!!! Our high today is to be 34..... first time above freezing in about 4 days!!! TYLER DOESN'T GET COLD!!! Get my room ready, I'm headed for your house!!

Great work OL.... AS USUAL!!! Your craftsmanship, thought and patience are beyond belief!!!

Dan.

forgive me but i didnt think there were gains to get out of an mtg2 after 4.5a?

Oh, there are certainly gains past 4,5A! Im running one in the 9-10A range.

Here is a chart made by djozz, taken from this thread.

thanks - i was looking for that specific chart but couldnt find it :slight_smile:

looks impressive!

Hmmmmm, looks like 12 amps would be even better. How many extra chips do I have lying around? Better charge up the 20R batts, so they are ready.Tongue Out

I would see how the setup works with 9A first and for how long you get 9A. There is really not much lumen gain after 9A, but you generate a lot of extra heat... And heat is something you already have enough of at 9A..
