Aluminium is extremely difficult to solder.
Also is not magnetic.

I did a second part of the pen video. Now with interchangeable tips.

So what?

Sorry... No english. I guess they will make some as soon as they are done developing and start mass production.

https://www.grabat.es/es/quienes-somos A branch of graphenano ( the spanish company that made world's first graphene ship) named Grabat is developing graphene batteries. There's very few information so far but the official news is that Chint (chinese energetic multinational) Has bought 25% of the c...

Copper needs 4s. 3s has no effect at all on It. I use Two 4s nanotech in parallel. The reason for wide strips is that copper on copper makes poor welds, also i like the wide tabs method, series and parallel at the same time,less work and much better conductivity and heat dissipation. Win win. Those ...

Nice video ty. Yes i think it could handle 0.12 because i did 0.2 after all but i do not recommend going beyond 0.1 This machine was not designed to weld copper but nickel. Pushing beyond the limits will kill the fets in no time. The Heat and difficulty at 0.1 is considerable. I didn't test It mysel...

I guess you didn't visit this thread for a long time. Yes i welded many copper batteries. That one is 0.1
I succeded welding 0.2 but it's too dangerous for both the machine and user.
0.1 is perfectly doable with the Boss welder.

I did a welding pen and i taped it. I hope it helps people to do their own welding pens.

Well after my failed experiment i did my copper battery as usual, this time i didn't tape it as it is prety similar to another build. Nothing new to explain so no point for a video.

Great! A build with video. I will add It at the builds post on the first page.

Well i have been sick and didn't talk about It anymore. The experiment failed. The nanolayer of carbon dissolved in the water so i don't know how long It would protect in real life conditions the tabs. It can be improved by applying more heat with the torch but since the tabs are so slim the metal w...

Nice build. Do you get enough torque with that motor?

I had some time today and an idea came across my mind. Coating frying pans and iron grills have been widely used on cooking for ages. The technique consists on burning the surface with a flame or a tiny layer of oil. Fish and omelettes tend to stick like glue when cooking. That coating makes them sl...

I think that motor Will have low Torque. I would use under 200 kv. 140-170kv and 6374 instead of 5065.
There's racerstar 140kv 5065 at banggood for cheap.

Oh i see the hole now. I have better light. Yes, you probably had a failure. Lee is sleeping now. Will wake Up in 4 hours or so.

The fet error message means:
Underpowered battery(is It full?)
Failure
Reload your lipo and check carefully the machine. Look for burnt traces. If the machine does not resume work mail lee. He Will tell you what to do.

http://i63.tinypic.com/2l88as9.jpg I did the test outdoors under the Sun so the settings can’t be seen easily. I started from 4ms X2 Up to 9ms I think 4-5 ms X2 is enough. Beyond 7ms is too deep with my setup. Notice that nickel on nickel might need higher flux. If you weld on the same spot that yo...

4s on nickel 0.2

Just tested 4s on 0.2 nickel. It's more difficult than 3s but perfectly doable. I recommend 3s for nickel, if you only have 4s adjust it slowly and you will make it (depending on your setup)

I LOVE this thread. Amazing job.

"graphene" has indeed been abused lately. Many products put that Word in their products even if they don't have It at all. I think this is genuine graphene this time. MIT has a well deserved reputation and there's no need to sell smoke. Those golf balls.... I have my doubts. Maybe they add nanotubes...

It seems MIT has done It. Right now it is a slow and delicate proccess but possible anyway. Focused on extreme efficient filters atm. Video of the machine included. http://news.mit.edu/2018/manufacturing-graphene-rolls-ultrathin-membranes-0418#news-video-block Nanotubes of graphene are possible time...

Yes graphene has been reported to work fine. I use nanotech, they are flawless. The burst is the key. High burst and at least 4000 mah work fine as long as It is not overrated. Graphene and nanotech have around 130C burstX4 ah= 520 amps pulses(in theory) the machine is rated for 880 amps. For good w...
