Hey element14 community,
I'm new to element14 and new to pretty much everything on this site. I need help designing a small pcb to fit into a mechanical mod, which is used for vape smoking. I believe in these products because they are giving people a chance to quit smoking tobacco. However, I cannot believe at some of the prices of these units. Because of this I've started to make my own "box mods." I am using a hammond 1950G enclosure (http://www.hammondmfg.com/pdf/1590G.pdf) and the following part:
Mosfet: http://amzn.to/1wPvWth
Battery Sled: http://bit.ly/Battery-Sleds
Fire Switch: http://bit.ly/Fire-Switch
510 Connector: http://bit.ly/Standard-510-Connector
15A Resettable Fuses: http://amzn.to/1s1BJVC
15k Ohm Resistor: http://amzn.to/1nV6mj8
ON/OFF Switch: http://bit.ly/Slide-Switch
I've been using the following wiring diagram as a basis of how I wire this thing up.
However, now that I've gotten used to wiring this thing up I've realized this isn't the best way to do this and it consumes way too much room in the already compact hammond 1950G enclosure. Is there any way a pcb could be designed to house all of these individual parts and fit into the enclosure along with the battery sled?
I would appreciate any advise, and remember I am very new to pcb and circuit design in general so take it easy on me
