i find soldering the stipped area flat then running the wire to a traceless area on the pcb and a dot of hot glue can improve longevity of your soldering and the flex in the wire.
You're right that this is just a part of a larger project. I'll have more videos on the larger project soon. As far as accuracy, it can measure well below a single gram, however the readings vary about +/- 5 grams. And over time the values can drift a bit with temperature, so the actual accuracy is probably closer to +/- 50 grams. So it's similar to the accuracy the scale would display out of the box (0.1 lb).
@@SharpWorkshop oh, that's neat, I look forward to seeing what you come up with. Would be cool to have plus or minus 5 g accuracy if you accounted for temperature drift
Hmm, this got me thinking about something... If you had this much trouble soldering since it's quite small and dense, how was this originally mas produced? Robots? Cheers! - 🐧
Now that they offer LabVIEW Community Edition for free, it makes it easier to use on these little hobby projects. I use it mainly because creating a serviceable UI is quick and painless. Full disclosure: I work for NI on the LabVIEW product for my day job.
@@SharpWorkshop So, it's labview. Pretty interesting stuff. Maybe people would look at me puzzled if I use autocad, nowadays nobody uses that stuff. I mean, labview is cool and probably used a lot, what I'm trying to convey it's fascinating to see something which I would never came across because it's not my field.
@@SharpWorkshop I learned labview for work as well, and I'm loving the community edition for special projects! It was a smart move by NI. I think you're the first maker on RUclips with labview, y'all should really encourage more users. LV is great!
Why didn't you put the wires in the holes and then apply solder, if you ask me you're just making it more difficult to solder them like the way you did? 🤔
That's usually how I do this sort of thing, but the wires are so small that it just wasn't working to do it that way. Once I stripped the insulation from the wires, they were stranded wires that were roughly the diameter of a strand of human hair. I'm not sure what gauge they were, but they were tiny. The fastest way I could find to do it was just put a little solder on the pad and then heat up the solder and dip the end of the wire; the wire was so small that that was enough to heat it up and make a decent solder joint.
Hacking a bathroom scale? Dude... there's easier way to get divorced!
but much, much less expensive!

So what is the end goal? And will this be any more accurate than it was out of the box?

all you gotta do is go back in time and say "I dont..."

I'm kind of curious about that as well. Let me know if you find out.
solder paste and a heat gun saves years of time
flow ovens?
First time I've seen a hobbyist use labview in RUclips hack project... very nice. Only question... what's the scale mod for?
You answered my question, what on earth is that software you are using. Thank you, looks like a serious learning curve to use it though

I'll have to leave you with some mystery on what my final project is. :-)
I'll make a video on that project before long.

@@SharpWorkshop Ok, seems like a good reason to do it like that then. 😋
