Homemade USB Passthru killing Atty's

[kgokal]

Ok, finally able to post!

ANyways, i made my own USB Passthru, hooked it up to self-powered USB hub on my monitor.

Vapes amazingly.... on a slightly used 510 Atty.
2 days later its dead, no heat, Infinite resistance on MultiMeter.

Chuck it up to lifespan exhausted.

Try a spanking new ATty, 3 days later DEAD.... Infinite resistance.

What am i doing wrong... i only hit it 2x every 30-40 mins.

Plenty o' juice.... am i giving it too much juice?

PS. Sorry for multi-post. Only now got ability to post own thread.

how many volts are you running???

Well im using USB port, so im guessing 5V@1.5A is what USB2.0 spec is.

Maybe i should test when i get home.

i would highly recommand you test it before puting another aity. on it ..you might have a short some where or you might be running at alot higher then 5v do you have a 5v regulator on it???? because you power supply could be jumping around and its not a steady amount of volts going to your aity. and that could be why..........

I've read around that 5V Regulators not needed on USB versions,
so i didnt bother but i'll definitely check it out when i get home.

I did check for shorts during assembly, so i dont think thats the case.

The USB port should be at 5v. I can't think of any way to incorrectly wire that to be an atty popping machine. If I had to guess I'd say really bad luck.
I'm sure it would be quite obvious if it were the case, but any chance the switch is sticking and burning them out while you're not looking?

When I first started using 5V mods, I popped 3 attys in about 7 days, but then again I've had some that last a lot longer. 5V WILL find your weak attys and eliminate them from the herd in pretty short order.

Use drip rather than carts on your atty so they stay moist and don't overheat, keep your draws (puffs) shorter than when you were using 3.7V (don't lean on the button, you'll overheat the atty). Remember that 5V runs through the juice quicker than 3.7V, so if you got four or five good draws from a couple drops on the atty at lower voltage, expect two or three at 5V.

Moisture and not overheating the atty will go a long ways towards keeping them alive when running at a higher voltage.

awesome tips, i just wasnt sure if this is unheard of...

Thanks guys.
