Hello. My project is a little stable already and I'm pretty sure the diagram won't change anymore, it's all about software now. But I need something more stable and more portable, that I can take with me and try outside of my office.
But that's nearly impossible, with 50 wires hanging out out of the bread board. It is very flimsy.
What would be the next step? All I have is a teensy4.0, a LCD, a steppermotor driver and also an 9 deg IMU that need to talk to each other.
I would think either a soldered proto board like one of these..
There are many configurations. Some have holes with copper on both sides. Some have strips of copper for bus and groups of 5 holes with copper connecting them together.
As @JohnRob says, using a proto board is a good way to go. Just remember.... When You solder wires some tin walks up inside the insulation and makes that piece of the cable a bit more stiff, less elastic. Secure the wires in way that they don't "fly around", move, because when aging it is a weak point.
Could You post a close picture of the bread board showing the wasp nest? Joking! That could give us a good idea about the type of proto board copper pattern.
I make headers, and solder the headers together. A whiteout pen let's you mark the physical orientation of the headers
I make mounting templates in Libre Office Draw for the modules, use those to drill and tap plastic to mount the modules. I prefer long screws through the back side of the plastic, nylon nuts as risers in the front, and nylon standoffs for easy grip nuts to hold the modules
I have some "big plans" to make some custom boards but I ran into "issues" with most of the software (mostly because it's "hard" to learn) and I've been distracted & procrastinating. I think I'm going with DesignSpark.
I have built a few of permanent projects on a breadboard and used them for years. One was a car alarm and it worked for almost 20 years (not an Arduino project). But nothing with 40 wires coming out.
For handbuilt projects with wires I suggest using silicone wire.
I've used PVC, IPVC, Teflon etc and nothing is better than this stuff.
it is super flexible, I would even call it limp. It has so many strands it virtually never breaks from bending.
doesn't melt when soldering. Connections look great and solder doesn't wick up as much.
strips easily.
I use mostly #28 for Arduino inter connections and #24 for power. Don't be fooled by the light gauge I've suggested. It handles all the current you will need.
I'm a big fan of stripboard. It is sometimes possible to make the design a little more compact using standard protoboard, but you have to make every single electrical connection, either with wire jumpers or solder jumpers. The stripboard is nice because the strips provide many of the electrical connections for you. And making efficient designs is a fun exercise. I like the style of stripboard that has solder mask over the strips because the more common kind with the bare strips is a little more difficult to solder due to the solder wicking along the strips. I usually only pull out the protoboard when I have a double sided design and so need plated through holes.
It's hard to see from the picture, but the one JohnRob linked to is like that. Adafruit also sells them as their "Perma-Proto" product line.
If you do end up with a stripboard or similar board. Be sure to clean it with a mild abrasive before starting to solder. I have some very fine steel wool that works great for me. But be gentle, you only want to clean of the oxidation. Then clean it with some dishwashing liquid and dry it off.
The cleaning removes any oxidation on the tin makes it real easy to solder. You will get better "wetting" and take less time with the iron.
