Soldering for product

[gallus1234]

I want my home project to look like an industrial product, or at least closer to that.
My Arduino board has only one GND (MKR NB 1500) but the attached sensors (4 pieces) all use this GND which I have no pinned together on the bread board.

How can I make this look more "industrial"/"product" like? My inital guess was a PCB board like this where I solder all the ground pins together. But this does not look very pretty. Are there any pin bars that are already connected?

All that, and no images?

Soft Hold Down Attachment for Component Soldering Further to Post #813 The old sharp tipped Hold Down tool, works well for most SMD components like 1206s etc. When it comes to bare wire busbars or MELF diodes, it can be quite challenging to solder them properly on your prototype PCBs.

@anon57585045 you are right, here you go:

...its a mess. Would love to see pictures from other projects, how they did wire and component management.

If your project is completed. You can design a PCB and Mount Arduino on it. Also desoldering female header will give it more industrial look

[gallus1234]

Okay, any link to where to do this for small batches or prototypes?

[amitf]

You can order from PCBway or JLCPCB or any other manufacturers which serve in your region.

If you only want to connect several cables with the same potential you can also use Wago clamps. However, the cables should be min. AWG 28 or thicker...

They are available for 2,3 or 5 cores.

Does (or did) your MKR NB 1500 look like this?

I can't see the male pins under the board on your photo. I would expect to see them where I have drawn red lines here:

Did you cut them off, and that's why you couldn't plug the MKR NB 1500 into your Breadboard?

If they are there, can't you just solder female headers to stripboard and plug the Arduino into those? Or solder directly to stripboard?

Here's a circuit I have just begun building on stripboard, to give you an idea.

So far I have only built the voltage regulator circuit and connected the +3.3V and ground wires to the other components.

You can break the copper strips using this tool, like I did in the image above:

Op already mentioned that he don't want to use that

@PaulRB thanks for input. The stripboard is something I could use at this stage with soldering female headers, or directly soldering the pins. And yes my MKR has male and female headers, which I did not cut off, they are just no visible.

Summerized, I was looking for something like the stripboard, where at least a row of wholes is already connected like in a PCB. But a individual PCB would not pay off at this stage so I think the stripboard is what I am looking for. Thanks also to all the other input. Loved to read every single one.
