I ended up buying the load cell from another company. What I find odd is that Sparkfun’s load cell selection is for large load load cells. It is almost like they have fallen victim to the “bigger is better” mentality. There isn’t, or at least wasn’t (I haven’t checked again), a single small load cell among the selection. Large load cells have their place, but I suspect that most hobbyists would rather have the smaller cells.

I just received mine. I need one gram resolution, so this will not work for me, but I am also metrically challenged and didn’t realize the dimensions. :/ This thing is MASSIVE! It’s 5 1/8" long x 1 ¼" wide x 7/8" tall!
Of course I could have looked at the picture with the handy rulers, but that’s crazy talk! That’s like reading a manual. No one does that!

2 km of four strand wire for $57?! Screw the load cell! I’ll take two!
Thanks for the reply! That was the information I was looking for. Now that I know, it seems obvious, but before I was struggling to understand load cell ratings.
I ended up ordering the 10 kg wide bar load cell. :/ Seems that may have been a mistake as well…
What is the resolution? I do a lot of baking and need at least 1 gram resolution. I’ve been wanting to make my own scale for quite some time.

I like Sparkfun and I support them. The only time I buy electronics elsewhere is if I need it quickly and Sparkfun is out, or if Sparkfun doesn’t carry what I need. It’s $5 well spent, IMO.

It’s sad that the digit isn’t symmetrical. I’m making a digital clock out of four of these and missed that the center segment is closer to the top of the digit. I was going to flip the 3rd digit over so that the two decimal points would form a colon. :/

Well, I feel stupid! Always read the specifications!
So the shift is required then? If so, that means the TWI library and software libraries I’ve used have a bug in them.
Thanks! I don’t have any tools, so I would never have been able to figure that out. That logic analyzer isn’t that expensive. I need to start collecting tools.
Where does this shift occur and is it part of the i2c specifications? That cannot be right.
No public wish lists :(
