gerax07 Posted July 31, 2015 Author Report Posted July 31, 2015 A friend and I got together and decided our next step from mech was to build our own boxes, and so we decided to buy the dna200 and make a great box out of it, one for each of us, and have an amazing time while doing so. I just wanted to check with y'all, since y'all seem to have a lot of experience when it comes to this particular subject. This is my part list, do y'all think everything is good? Please feel free to tell me if any parts will conflict or if we're doing something wrong.Battery:http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=8932Enclosure:http://www.ebay.com/itm/Alpinetech-1590B-MBK-CNC-Milled-Aluminum-Enclosure-Box-Hidden-Magnet-BLACK-/221838484690?hash=item33a69aa4d2Fire switch:http://www.ebay.com/itm/MB16F-W-ATI-16mm-Momentary-White-LED-2-8V-4-3V-PushButton-Switch-Flat-Top-Black-/321633536740?pt=LH_DefaultDomain_0&hash=item4ae2da4ae4Up/Down switch:http://www.mouser.com/ProductDetail/CK-Components/KSJ0M43180SHLFT/?qs=sGAEpiMZZMtn8lxF5bBjIcLvXe4ql53t510 Connector/Cap:http://www.fatdaddyvapes.com/shop.html(What size do y'all recommend?)Magnets:http://www.ebay.com/itm/N52-Black-Magnets-for-Hammond-Box-Mod-4-1-4-x-1-8-Disc-4-1-8-x-1-4-Cylindr-/321780355551?pt=LH_DefaultDomain_0&hash=item4aeb9a91dfResistors:680:http://www.mouser.com/ProductDetail/Vishay-Dale/CMF07680R00GKR6/?qs=sGAEpiMZZMsPqMdJzcrNwmyXKdlxrkSRaUdyGRk3zIU%3d4k7:http://www.mouser.com/ProductDetail/Vishay-Dale/CMF604K7000FKEK/?qs=sGAEpiMZZMsPqMdJzcrNwmyXKdlxrkSR2Dvt3Ie3RX8%3d10k:http://www.mouser.com/ProductDetail/Vishay-Dale/CMF6010K000FKEK/?qs=sGAEpiMZZMsPqMdJzcrNwohr4TA0SfZbzszyc8DC8m4%3d20k:http://www.mouser.com/ProductDetail/Vishay-Dale/CMF6020K000FKEK/?qs=sGAEpiMZZMsPqMdJzcrNwohr4TA0SfZbQvpr%252bFn8STI%3dPN2222A Transistor:http://www.mouser.com/ProductDetail/Fairchild-Semiconductor/PN2222ABU/?qs=sGAEpiMZZMshyDBzk1%2fWi8oN7VHZ91Oksd99mJbzy1A%3dMale XT60 Connector:http://www.hobbyking.com/hobbyking/store/__43759__Male_XT60_connectors_5pcs_bag_GENUINE_USA_warehouse_.htmlWire:http://www.hobbyking.com/hobbyking/store/__466__377__Hardware_Accessories-Silicon_Wire_Mesh_Guard.htmlI really appreciate it, and any input or tips y'all have will be very welcomed.

John Posted July 31, 2015 Report Posted July 31, 2015 What are the transistors for? The fire button of the 200 goes straight to positive battery voltage (9-12V) and is active high, you can tap power straight off it (with an appropriate limit resistor) if you want. Or if you are feeling especially adventurous, there are pads around the onboard fire button for LEDs, but that is a difficult solder job.

Well, we want to wire in an LED fire button, and have it only light up when we fire the mod. Wouldn't wiring the LED straight to the board make it always be lit up?

Attach a 100 ohm resistor between the 2 pads on the left above the screen-printed 'F'. Resistor linkAbove the fire button, near the board edge and slightly off to the right, you will see 2 identical small solder pads. Attach your LED there, cathode side toward the middle of the board.That will give you what you want.

We can't figure out where we would need to solder the resistor. And by doing so, do we not need any of the other resistors/transistor?
Brandon Posted August 1, 2015 Report Posted August 1, 2015 We will put one together with an LED and post pics but probably won't be until next week.

gerax07 Posted August 10, 2015 Author Report Posted August 10, 2015 Hey y'all, I found this 100 ohm resistor from an electronics company that is close to me. It is almost identical to the resistor Brandon posted, but it has a 50V voltage rating. It's this. Y'all think it's OK for my build?
John Posted August 10, 2015 Report Posted August 10, 2015 well, that's an 0603, so a little larger, but it'll work just fine if you get it soldered on.
scoopy Posted August 11, 2015 Report Posted August 11, 2015 Still curious and would like to see the board with the led fire button whenever possible
kpvapesalot Posted August 14, 2015 Report Posted August 14, 2015 The remote switch lines don't run power? so if i mount a remote switch with an led in the traditional way it wont illuminate?

jurdanas Posted September 15, 2015 Report Posted September 15, 2015 Who did that with LED?Who can show schematically (photos, pictures)?Please.Regards

Spector NS5 RD Posted January 22, 2016 Report Posted January 22, 2016 looks correct hard to tell for 100% sure from the pics. have you looked at this thread?https://forum.evolvapor.com/topic/67162-topic/?do=findComment&comment=904565
Ononewheel2 Posted March 9, 2016 Report Posted March 9, 2016 Sorry but im new to the resistors but why are you using a 100 ohm resistor . Can someone explain that in detail . Can you use a smaller ohm or bigger ohm resistor in its place . What are you using to calculate this for the dna 200 chip to know which one to use?

What are you using to calculate this for the dna 200 chip to know which one to use? you don't need a resistor for smd leds. that set up is for adding a push button with built in LED's here's a link if you want to add LED's. https://forum.evolvapor.com/topic/67162-topic/?do=findComment&comment=904565
Ononewheel2 Posted March 9, 2016 Report Posted March 9, 2016 I don't want to use an smd led my plan was to wire a push button led directly to the board . It has 4 pins . 2 for the led pos neg 2 for the fire . I found this diagram that some said they are gonna use and this is how i want it . Is this possible? .

Is this possible? .yes thats the correct diagram. i thought you wanted to use smd leds. sorryTBH, i'm not 100% sure on the 100 ohm resistor. i think the LED voltage determines the resistor value.

Do you happen to know what info i would need to find what resistor i would need for it to work .
Ononewheel2 Posted March 12, 2016 Report Posted March 12, 2016 I found this online on a resistor calculator but what is the source voltage on the dna200 chip and where are you getting the info from. Source voltage diode forward voltage Help diode forward current (mA) Help

Source voltage diode forward voltage Help diode forward current (mA) Help this what i found for a BLUE (same for WHITE) led mitec switch. supply voltage (pack voltage)=12 diode forward voltage= 3.2 diode forward current=28mA. i would open a ticket with evolv to make sure on what resistors you need, if any, for your led switch. your post (#22) is the correct wiring diagram.
