Printed DNA30 Bottom Feeder

[Cool_Breeze]

It seems I read a while back that someone destroyed their dna by inserting a battery backwards. Thus, I would assume it doesn't have reverse battery protection.

Should consideration be given to the addition of a diode for reverse protection to the printed bottom feeder?

 

[KurrptSenate]

you would need a mosfet for that (reverse battery protection)

a diode, like a zener diode, would be to prevent you from over-drawing current from the battery

well that's going to hold me up and possibly write off this project for me - I've looked everywhere and aside from mouser can't find these fuses anywhere but there - and they are not expecting them in until the end of October..

Plus with their set rate of £12.000 GBP for shipping - just two of these fuses will cost me $27 dollars -- it just might be the straw that brakes this projects back for me unless I can find an available alternative to go there instead.. and personally for me I never go above 12 W in any of my mods... the only other poly fuses i can find are 6a hold with a 12a trip with a max V rating of 30V but I've no idea if they would fit in the available space of the mod case or not..

alternatives for the fuse would be appreciated if you can suggest - otherwise - it will be a non-starter for me as that is one of 2 parts that will hold me up - the other is ironically the small SS nut needed for the fat daddy 510 mod - not available in the UK - and have to buy in packs of 100 from the US again at SILLY prices

Fuses in stock here: 2920L700SLPR

You dont need to use a fuse, lots of devices both regulated and mechanical dont have them.

The 510 Bottom feed set up and parts I posted is just one way of doing it. It really doesnt matter what type of SS screw you use, so long as it can be adequately insulated. The Fat daddy 510 has a 7 mm ID. So use what you got and size appropriately.

Easy source of vented screw is the key for me (and mating nut). I do not have means to make one myself

Stand by on the drilled screws folks; the Beta team is working on sourcing a good-sized batch of them.

 

[Darthpistachio]

cheers for finding that fuse in stock - I will have to think long and hard on whether I will get them though as Digikey also have a flat rate of shipping policy of £12 GBP which means two fuses will set me back £16 / $28 dollars roughly -

factored into the total cost - it's not an insignificant amount and my principles really prevent me from paying 12 postage on a product that weighs less than 2 grams...

I think I'll probably add a search to ebay and get them if they ever turn up on there with reasonable shipping costs..

I hope it works out because I don't have a dremel even to attempt such an operation. I prefer to have only soldering to make. Thanks.

The guys out of the US should checkout the group buy thread. I think they would benefit the most with this option.

Yes indeed

I have a dremel with a large array of bits, as well as a power drill. This specific task needs a drill press, and even then it is a pain, as per gdeal.

For what part/parts do you need a drill press?

 

[BobC]

If you had to drill out the 510 insert screw for bottom feed

 

[BlueSnake]

I think that's why they are trying to get the 1/16” pre drilled screws.

 

[Kataphraktos]

Yup, I was just mentioning that doing it with tools that are usually available isn't really an option. Even with a drill press, it's a pain. We've spent a lot of man hours looking for a vented screw that could be used, but none fit the bill, so the only way to get the right specs for a perfect BF 510 is to have the perfect screw custom drilled. On another note, I know more than I care to know about vacuum vented screws.

Amen, I have also spent a considerable amount of Googlefu looking for something to fit the bill for everyone else, even though I used Reo pins.

gdeal has found someone willing to take on the task of drilling out all the screws as there isn't an easy, off the shelf item to accomplish what we are looking for. That is figured into the kit price.

Having done that myself, I can tell you it isn't an easy task. It's not hard to do, just hard to do well and its time consuming. I broke off a bit in an Odin pin last week at a point where it is screwed now.

How exactly did you modify these 510's to have the pass-through positive pin for the juice flow?


Thanks,

It's all explained in this thread with visual diagram.

That's the post I was talking about. It doesn't actually say in the post you drilled it nor does it show a hole in the screw lol.
