@Dbanner,,Cheers,,yes, it's a boost converter, my mistake. @Sabios,,,yes, you can use the one in your photo,,that's the same one I use. I use mine with 3 x 18650,,each battery of mne has 3600mah,,but recently I used 4500mah and it lasts much longer,,8-10 hours,,plenty enough for a day out. Regards,,Marty

Hi all,,,I have made 5 successful Felezjoos up to now and find that the best voltage is 18v,,,I use 3 x 18650 with a buck converter to boost it from 12v to 18v and it lasts me about 5-6 hours detecting time,,also, I have no problems (Touch wood), up till present using a 300uh 2.5 ohm 3dss coil with either of the 5 builds,,,they all work equally as good as each other. Regards,,,Marty

Boost converter.

[sabios]

I can use this booster to raise to 18 v, I guess this is true.

that vateria recommend me 12v rechargeable acid or 3 18650 for 12v

No problems with this version 24v battery will heat a regulator 12v and will be unstable

a question, then the felezjoo full edit 3.35 is a full version or has a problem is that I'm thinking about starting over.

another question, this type of batteries believe it is good, we said connecting 2 batteries in series to give the 24v

@Timekiller,,,I use both these Hex files and they both work fine for me. Regards,,,Marty

Hello everyone . hex 3.35 is it last ? Is there another version after 35 ?

[ricalbertvig]

with this program you can edit the .HEX but I do not understand which part to modify

Send nice message to author, thanking him for a great project. Then ask him to customize the code just for you. Maybe he'll be sympathetic.

Yes, its very simple. Pay author 20 000$ or what was price of original code and just change text
