another dna40 wiring question

[sadlercustompaint]

So everything is ordered, just wait in on the chip and switch. I went with a 2.8v LED switch. I know how I am wiring the switch but do not know what resistor to use. Here is the specs on the switch

 

[dre]

The specs say the correct resistor is included

 

[sadlercustompaint]

For 4.3v. The way I'm wiring it, the led will be connected to the output power of the DNA, so 1v - 9v. If I use the one it comes with it will most likely blow if I take the chip past 4.3v

 

[dre]

Why would you do that doesn't it turn on only when pushed? Your gonna blow it.pushing all that amperage. The led only turns on while pushed by what Tue spec.says so wire it to battery. Unless you know different.

 

[sadlercustompaint]

Unless the voltage to and from the fire button stays at 4.2?

 

[dre]

The dna40 output us around 1-2v usually during temp mod. I'd get a button that uses battery power which by what I'm reading you got.

I'm not sure if the led has a circuit in the switch to only come on when it's pressed. In the pics when I ordered it they just have the neg and pos of the led hooked up to show the color. (Without pressing the button). So that makes me believe it needs to be wired to a hot that is only active when it's fired, witch would either be the return wire from the switch to the bored or the hot wire to the 510

Ig I'll just have to wait till Wed and see what it is. I'll just hook it to the bat with the resistor to see if it lights up without the button bein pressed

What happened?

 

[sadlercustompaint]

It has no internal circuit. But it came with a wireing diagram that shows exactly how I planned to wire it so it must b fine to do it that way. Resistor from LED straight to power out of switch and ground to battery

How's your build going @sadlercustompaint

 

[sadlercustompaint]

Well was going great until Monday. Took it to a new business that just started up for powder coat, and they completely jacked it up. Looked like white bed liner. Had. Hair and sandpaper residue in the clear. So now it's at a buddies shop being redone. After that I just have to airbrush is, clear and put the components in.

 

[sadlercustompaint]

Only pics I have so far

Looks like your holding the soldering iron to long on the contacts. It should only be on there for a second tops. To much heat will shorten the boards life or damage it. Just be careful
Or its just flux ya didn't clean off that looks Lil burned

It's just the flux. I use alot. Seems like the more flux I use the less contact I need on the board to get it hot enough. I cleaned it all up no burns. I have a bad tip on my iron. So if I feel like it's takin to long I pull it away and give it a little wile so I don't hurt the chip. Still waiting on the powder coat was hoping to get it back today but doesnt seem to be happening

 

[dre]

I thought it was flux you can use rubbing alcohol and a paper towel to take it all off

Yup I used alcohol and Qtips

Very smart........great build!
