Finally here!

My dna 20 chip is finally here!!!

I think I have everything but a battery holder but could you guys double check?

Also could I make this work as a battery holder?

If i sodder a wire to each contact could that work? I'm thinking I'll plant each end in a small wooden enclosure and make my own battery casing.


EDIT: also just to warn you this thread is going to be picture heavy and filled with questions as I will need your guys help every step of the way. I will be using it also as a tutorial so maybe others can get info.

Afternoon bump with another question. How do I connect the tactile switches to the board?

 

[something_vague]

Your tactile switches need to be checked for continuity on which legs are actually on opposite sides of the switch. Most tactile switches will have 4 legs, you will only use 2. Think of the legs as pairs. Measure resistance between each leg and when you get the open and closed continuity with the operation of the switch then you should get your legs that you want to use. Not sure if I wrote that to make sense. You need to solder a pair of wires of the switch to the up +/- and another pair to the down +/- on the dna board. It doesn't matter which side of each switch goes where in terms of + or -. The tactile switches have no polarity associated with them. And yes a custom made battery holder is perfectly fine but I would consider making one side of the battery holder springy so as to get the battery in and out for charging as well as get a solid connection once in place.

This is my first mod and I have absolutely no experience about electronics.

So unfortunately that made absolutely no sense....

Could you dumb it down a bit more and how would I check the resistance like you mentioned.

Ok, first question is do you have a multi-meter? You basically want to check for resistance between each leg. I am not a photo shop guy so I can't draw a pic. But there will be 2 legs on this switch that show close to 0 ohms (depending on calibration of your meter) no matter if you're pressing the switch or not. Then you need to find the pair of legs that shows an open circuit until you depress the button and hold it which should cause the resistance to go to 0 ohms. This will go back to open when you let the switch go. That is the pair of legs you want to connect to your DNA board.

It is very difficult to explain this but it sounds like you really need to do some more research on the subject. I'm sure there is something out there on the internet that explains this with pictures and all. But you really should have a decent multi-meter and a decent understanding of electricity.

Yes I own a multi meter, and now that makes sense. Sorry I didn't understand your first post but you cleared it up. I know what I gotta do now thank you
