thats funny because thats exactly the one in my cart as we speak, now im looking for good solder wire lol

thanks sal, much needed info !

Might also want to get a fine point tip. The one it comes with has a flat angled edge, but I found a ST7 tip to be better for precision soldering.

...see the vids... and the tips they use... ...you maybe need a little flat too...

...with a good tecnic you can use a bad solder and do the job too... all its practice...

pd1...about the tips... ...from sparkfun tutorial ...how to solder through hole soldering...

• Tips - No iron is complete without an iron tip. The tip is the part of the iron that heats up and allows solder to flow around the two components being joined. Although solder will stick to the tip when applied, a common misconception is that the tip transfers the solder. The tip actually transfers heat, raising the temperature of the metal components to the melting point of the solder, and the solder melts accordingly. Most irons give you the option to change your tip, should you need to replace an old tip or if you need to switch to a different style of tip. Tips come in a variety of sizes and shapes to accommodate any component.

Several types of tips. From left to right, the bevel tip (aka hoof tip), two conical tips with varying widths, and the chisel tip.

Changing the tip is a simple process that consists of either unscrewing the wand or simply pushing in and pulling out the tip

...for my pov... the more usual for medium or litle works... for me.... its the little chisel (i dont know her name or model my bad and short english ...but the conicals are used for me too...i agree with most of tecnics or preferences showed on the first vid i posted on my previous post...

I'm using the same one - it works great. I would also agree that a fine point tip would be worth the cost, as the flat-head tip that comes with the solder package isn't ideal for the work I've come across with DIY COB projects.

@Cococola36

Although if you have prior experience with soldering, you could get away with the flat-head.

Most importantly though, regardless of what ratio of tin/lead you end up with, you must protect your body from the nasty smoke that emits from the solder. I actually use a strap-on mask (sorry, I don't have link or photo) that you can pick up at Menards or Lowe's or Home Depot for around $30.

Again, do not cheap out on your health, not to mention the smoke, if inhaled, gives you the worst buzz/high. Then after, you may feel quasi-retarded. This has been my experience.

One last tip - you shouldn't have to raise the knob on the solder station pass 3. I usually go quick at 2.5 but everyone is different.

So an update on project "Apollo Creed" no pun intended for cree lol as its vero's but that would have been a cool name now that i think of it haha. I had some help from a buddy who is also eager to learn the ways of COB. And to my surprise.....easy as fuckin pie...have to agree with a few people on here and say its true. I don't know what I was so concerned about. But thats no bad thing. BUT lessons were learned first! So it seems my power supplies were set up in parallel.....AFTER figuring that out the hard way that the cobs needed to be connected in certain fashion in order to get the right amount of voltage passing through them. Here my friends is a pic of a vero 29 running at 392 watts accidentally yup you read it correctly ...
This obviously resulted in a smoking cob that lasted about an hour before burning leds out lol. I'm oddly proud of that. Either way a learning experience to say the least. And hey you have to wreck one cob to appreciate it right?? After realizing that it seemed EXTREMELY bright to my expectations lol, I knew something was definitely wrong. So i hooked up another cob for about 3 seconds just to get the reading from the wattage meter annnnd boom 416 watts from the wall! Uh ohhhh, quickly turned it off and realized just how the drivers worked. I only had 6 out of the 8 drivers hooked up and did the math. Without any leds on, the unit draws about 24 watts with 8 fans. Thus resulting in an astounding 392 watts flowing through the single cob..ouch.

So after setting up 6 cobs with the 6 connected drivers it ran beautifully and was running very cool at that. After about another hour ambient temps only went up roughly 8 or 9 degrees. The wattage from the wall with the six cob was at a perfect 336 watts, 312 for the cobs giving them the correct 1.4 amps @52 watts per cob plus the 24 watts for all the fans.

I still need to figure out exactly how I will space them out and mount them. As well as wait for the shipment of another cob to replace the unfortunate death to the one mentioned above. Also I will be soldering each connection to the drivers and using heat shrink tubing to secure them, So once done I will have 8 total cob and it should run at 440 watts total draw. Once I can get a hold of some ledil reflectors that will finish the build. This build anyway hahaha.

Much appreciated info as I will not cheap out on my health, I need to outlive these cobs haha Thanks Aquarius

Wait, you had a single Vero 29 emitting ~300W longer than 10 minutes without any visual problems?!

I don't know of anyone that has elevated the limits of the Vero as you have demonstrated, CoCola. Bravo!!!

 

[medicinehuman]

Wow! maybe a world record 392w. through that make of cob. Good job.

Yuppp haha believe me, my buddy and i were blinded for about 20 minutes or so lol prob not good.

I'll take it a world record by mistake

 

[Cococola36]

A nice update, the build is essentially finished! I will still at some point look into reflectors, but for now things look great Thanks for all input and help from the riu followers of this thread.
Plants were supposed to still be in the dark period but I had to test this light out in the tent early lol

 

[churchhaze]

I personally think that weller is a bit overpriced, and that there are much better options out there for the same price point. I got this Aoyue 60 watt programmable digital soldering station, and you can set the temperature of the tip, and it will put out up to 60W to keep that temperature.

The tips are way nicer than entry level weller tips imo as well, and hold up a lot better since it's less likely you will burn the tips. The temperature control is great.

(Edit: Sorry I didn't answer this before you bought the weller station...)

Anybody know a well made soldering iron? I need one just in case and not sure about what brand or wattage is preferred

 

[Greengenes707]

Awesome. Super clean. A droned out apollo.

So you're going to flower those girls under it?

no worries, still waiting on my damn tips anyway...good ol fedex delays

Def can admit the design was extremely drone like lol and as for flowering, i will be flowering just one plant under later on. These girls have a few weeks more veg time before I can move most of them to the indagro/Cmh room. Next run will be big one plant per each light and slightly scrogged out.

Looks like the project turned out quite well for you, CoCola. Congrats! Was this your first DIY project or?

 

[NapalmD]

Looks awesome man! Those rails coming off the sides are genius for keeping the tent away from the light. I would have never thought of that and may need to do it myself on my build.

Thanks , it turned out a lot better than i planned. And yes this was my very first ,but not last, diy!

I am very pleased with the design , but can't take full credit for the concept as I got the idea from @Greengenes707

 

[Greengenes707]

Mine was just my own variation of gaius(http://rollitup.org/t/diy-led-grow-lights-with-cree-cxa3070-cobs-and-cpu-coolers.805681/).
Coco, yours has a little of both...and lots of your own originalness. That thing is a beast. It will do great for what ever you need it for.

Thanks man, wow I totally forgot about that thread! I asked him if he would make me one hahaha. I'm hoping the 3500k will work great for veg, it looks more like natural light than warm so I'm digging it. The light spread is so even in every inch of the tent I can't believe i waited so long. My cmh have much to worry about lol.
Anything different with feeding under cob leds that i need to be aware?
