Michael just shared a new tutorial: “Makerverse Load Cell Kit Guide | Measure Weights and Forces”
Introduction Welcome to the guide for the Makerverse Load Cell kit. With this hardware you will be able to make a set of scales capable of measuring weights up to 3kg with a precision as low as 0.1g!

I am sorry but I don’t believe I read that. I checked and double checked and it is true. That is what is printed.
I have almost seen people sacked over this sort of thing. At best they got a quick lesson in reliable connections.
Cheers and pls revise or think before you print. Bob

Just had another look at this.
It gets worse. From the pics it looks as if you have tinned the wire !!! THAT is a definite no no.
Cheers Bob
I was planning on connecting this to the Seedstudio Seeed Studio XIAO ESP32C3, running ESPHome and connected to Home Assistant. Have you tried this? Do you think it will work?

Hi Martin,
Welcome to the forum!
While I havent tried it, that doesnt mean it wont work!
At a glance the drivers are mostly the same, a basic driver may work with both a HX711 and the HX710 on the Makerverse board.
If you wanted to be on the safe side, ESPHome says it definitely supports the HX711 we stock here: SparkFun Load Cell Amplifier - HX711 | Buy in Australia | SEN-13879 | Sparkfun | Core Electronics

Hi
Thought I’d post the project I made using this Makerverse Load Cell kit. Its a device to remind me and my household to give our pets their daily medication. The medication sits on top of the scales. It has a 10mm LED which illuminates at 7am and 7pm and also has a piezo buzzer which goes off for 3 seconds at the same time. The LED extinguishes when one of the medications is removed from the scales.
The concept is to remind people to give the medication, either at 7 oçlock if they hear the buzzer or later if they walk into the room and see the LED lit up. It removes the need to ask “has anyone given the pets their medication?” as you can instantly tell from the state of the LED. The use of the scales to turn off the LED means there is no need to, say, push a button, to indicate you have given the medication as people will forget to do this and then you are back to asking the question!
It uses a Seeed Studio XIAO ESP32-C3 and a SparkFun HX711 Load Cell Amplifier. It connects to Home Assistant using the ESPHome hx711 sensor platform. I created one automation to turn on the LED and the buzzer using a time trigger and another automation to turn off the LED when the weight from the load cell changes.
I 3D printed the enclosure.

@Martin175958 Fantastic little project, super practical! Nice and clean enclosure as well.
Been looking to do some similar things around the house but by pushing a button or something, might needa see what can be load-cell-ified!

Thanks Jared. This is my second project of this type. The first was a medication reminder for me. I store my tablets in a bathroom cabinet. I added a strip of neopixels to the underside of the cabinet and a small reed switch on the door. Same logic as the pet meds reminder project.
