Ok guys I have a parts list for the okrt10, but i am a little weary on the wring of the parts. I have a couple questions that I am hoping that you guys could answer. Here is the list of parts that I have gathered and from what I understand are needed but i wanted to make sure that they are correct. I will be using 2 18650s, should they be wired in series or paralelled? Im not a genius but Im am doing this to learn how to build mods. I learn fairly quickly.

I cannot find the 16v 10uf capacitor, is there a good one someone can recomend? Is there Some thing I am missing from this list? is it possible to wire in an ohm reader/tester? Could someone possibly link a diagram for a okrt10 build that is current? I have been studying mamu works and greatly appreciate the information that I have aquired. I am srry If I am wasting any one times but I have gotten this far without nagging or asking questions. Thank you for any comments or methods.

Current drawing from Mamu: http://www.mamumods.com/pics/okr-t10-wiring.png
Source: OKR-T/10, T/6, T/3 schematic circuit

OKR T10 needs an input voltage of 4.5-14. Your 18650s need to be in series to output about 8.4v (2x4.2v fully charged) - 6.0v (2x3.0v discharged)

The capacitors are not absolutely need, but you can use them if you want or feel the need.
I ordered this cap before, but chose not to use it. FK11X7R1C226M TDK | Mouser

Thank you very much I appreciate it!!! As for the cap I should only need 1 right?

That knob has a 6mm hole for the shaft, your shaft is 5mm diameter. About two wraps of scotch or packing tape around the shaft would bring it up to size. That knob is physically large 32mm, around the same size as the width of your box. You can find some nice guitar knobs if your looking for a nice metal one.

If it is the same width I would be able to flush mount with the mjority of the switch in side the case and be able to adjust the dial from the side? Kind of like the older radios that have the dial that poke out and u turn it to change station up or down except it wont stick out as far lol thats what i picture in my head hahah.

Does this Look Better? The only thing I noticed that I didnt see before was the 2x5amps fuses.

Thanks for putting this together Killaq and all those who contributed. I received my okr-t/10 chips the other day. I'm still waiting on the other components but hope to have something completed by next week.

What gauge wire will you be using? I'm debating between 16 or 18 gauge. I'm getting a box custom milled so may need to wiggle the dimensions a little to get everything to fit nicely.

Thanks!

Oh, forgot to mention one thing. When I built my prototype, I also used a Hammond box. One thing I noticed with those boxes is the sides are not level. There's a slight pitch to each of the 4 sides. Apparently this is done intentionally because it is die-cast. The pitch is required for them to pull out the product from the die.

I'm not sure if this matters to you, but seeing the list when I set the box down on a flat surface didn't sit well with me.

Some Hammond boxes have that annoying tilt to them. With those some modders have filed the tilt off a bit.

@Killaq - I don't know which 510 connector you plan to use, but some use the Chi Yo Top Cap and some use fatdaddyvapes 510 Inserts. Either one make for a beefy and sturdy 510 connection.

@dragomoon - 20ga for input and output and 22ga or 24ga for all other wiring. It's your choice whether to use stranded or not, but stranded I feel gives better, more secure, connections. For best results, tin - apply a dab of flux then a small amount of solder - to all wire ends and connections before soldering together.
