Unfortunately Phant, our data-streaming service, is no longer in service. The system has reached capacity and, like a less-adventurous Cassini, has plunged conclusively into a fiery and permanent retirement. There are several other maker-friendly, data-streaming services and/or IoT platforms available as alternatives. The three we recommend are Blynk, ThingSpeak, and Cayenne. You can read our blog post on the topic for an overview and helpful links for each platform. The code in this tutorial will need to be adjusted to work with the other data streams.
HI. I recently order a couple of these HX711 PCB’s. Currently, i’m trying to get 80Hz sampling rate by using the rate pins on the back side of the PCB (on default the PCB only deliver 10 sps (or Hz) . However, I did not get this to work. Do you have any more specification on how to get the 80 Hz sampling rate to work?
Is it possible to use this with an Raspberry PI 3B+ . I thought that each hx711 chip could be used the same. I bought one on an german site and found a tutorial to use this chip (hx711 in green) with an raspberry. This chip doesn’t seem to work.
this was the tutorial that i followed
I have used two Load Combinators (BOB 13878) which work initially, and then fail unexpectedly. I had soldered on pin connectors and I am wondering why they seem to fail. Should I not make the load cell connections in this way? The guide shows the thin load cell wires apparently soldered directly to the part.
HEY! I’m really quite worried after buying four 200 kg load cells, 1 load combinator and 1 load cell amplifier that I may have screwed up. My load cells have 4 wires and the load combinator has only 3 inputs for the “load sensors” that a “Typical bathroom scale” uses. I understand this has something to do with the wheatstone bridge by I don’t know which 3 wires to use and what to do with the last one! Please help!
Is it possible to use this combinator if the load cells are not equidistant in a square? (and you want to have the same weight on multiple locations on the scale). For example when load cells are placed in a rectangle or an isosceles triangle?
There’s a Fritzing diagram showing this part already modeled, but I haven’t been able to find it anywhere.
Is it available? Many thanks!
