Cheap, short lead time PCB manufacturer.(If you have a sweet circuit.....)

[MonsterTKE]

I have been getting ready to fire up Eagle for for about 2 weeks now, figured on designing a 3 - 7v, 5 amp mod with a SMD atmel chip controlling the whole thing. Thought it would be kind of cool to track stats ie: Activation count, average activation time, time between puffs etc. Id probably have to use a micro sd card to hold all of that data though.)

Anyways I have been busy and lazy, so I am putting that off for the time being.

If anyone has a really good buck/boost design THIS PLACE is a good place to get them printed. If you grab the parts from Newark or DigiKey you could even put together a DIY kit,

I've been wondering about batchpcb, have seen this company mentioned as the manufacturer they use. Is this still the case? Been messing around with kicad lately, laid out the footprint for the ptr08060/08100 and wanted to make a super-compact board for it with SMD components. Just don't have the confidence that I'm actually doing it right just yet. Anyone with experience that can check my files to see if they look kosher for getting made up?

i had a thought recently about keeping track of usage and how lots of interesting things could be learned about vaping habits and such. I don't quite have the knowledge or funds to attempt it so i was quite happy to see this thread. Im looking forward to your idea being implemented in a pv.

Provari uses a Atmel ATtiny chip

Yes, this is the supplier that BatchPCB uses. Though you only get 3 copies of your design for that price, but you have to wait for the entire panel to get filled up.

If you get a prototype panel from gold phoenix you can panelize your design and get as many as will fit. It is beneficial to pay the $20 for electrical testing as they will generally run extra of your design to make sure you get the number of boards expected. $170 dollars or so bets you 155 Sq-in. of one design on one 2 layer panel. With a minimum size of 1/2" x 1/2". I figure with a tight layout, using all SMD components you can get 50 - 70 boards per panel.

Provari uses a Atmel ATtiny chip

I was thinking about using a ATMEGA328P-AU, no USB, and a very small SMD 5v regulator. I think the main programming challenge is managing the sleep state of the atmel chip.

Im very interested to use a micro controller to manage the battery.

There are a lot of ATiny chips, I havent dealt with a ProVari yet (though it is going to be my next big purchase).

Same here. Vari is a Attiny88

Yeah the only difference between those two chips is the amount of program memory. And I think the ATtiny has one additional I/O pin. If all you needed was a few buttons to change a Digital resistor value and display some values to a LCD the ATtiny is perfect. If you plan do include many libraries or write more complex control code the additional space would be key.
Not to mention the community support behind the ATmega chips.
