Pretty cool project, the LEDs are pretty nice!
In case the author or someone else knowledgeable reads this, is that application for the load cells used for sensing are able to handle? The load cells are rated for 50 kg (~110 lbs), and even if there are four load cells, the dynamic load might not be evenly distributed. It's also likely that the 50 kg limit is a static load, not a dynamic one.
- wiml 6y agoThe manufacturer's site lists the max load as 150% full scale, so there is a little room there. (And exceeding it probably just makes the cell go out of calibration, which might not be a big deal for a dance pad?)
- jfim 6y agoYeah I'm curious as to what is the failure mode for these sensors when they're run out of spec. As you point out, if the sensor is just returning an inaccurate it's probably fine as you're only interested in a relative load value (loaded vs unloaded), not an accurate reading. I don't have actual data with regards to this, but the instantaneous force applied to the load cells would likely exceed their spec in the case of a heavier adult jumping on the arrows or otherwise hitting them off center with more force than placing a static load on it.
