AI Thread Summary
Alternatives to the FlexiForce 1lb sensor are being explored due to its high cost of $20 each, especially for projects requiring multiple units. CUI was suggested, but inquiries revealed that their pressure sensors might be more expensive and require large orders. The discussion also highlights that cheap digital scales typically use resistive strain gauge sensors to measure weight, which operate similarly to FlexiForce sensors. It's important to differentiate these sensors from load cells, as they function differently. Overall, finding a cost-effective sensor solution remains a priority for the project.

Is there a alternative to the FlexiForce 1lb sensor. $20.00 a piece is rather high for my project, seeing how I will need multiple ones. Any ideas?

You could try CUI, but i don't know how much their pressure sensors might run you:

I gave them a call, the impression I got is I would need a huge order and is far more expensive than the FlexiForce. How is weight mesuared in those cheap digital scales? I am sure those are accurate enough for my purposes.
 
Electronic scales usually use some type of resistive strain gauge sensor to measure the displacement in a structure and back calculate the force from that which is similar to how the flexiforce things work. This should not be confused with a load cell.
 

Thread 'How might electronics be different if AC voltage was 72V at 45 Hz?'

Hey guys. I have a question related to electricity and alternating current. Say an alien fictional society developed electricity, and settled on a standard like 73V AC current at 46 Hz. How would appliances be designed, and what impact would the lower frequency and voltage have on transformers, wiring, TVs, computers, LEDs, motors, and heating, assuming the laws of physics and technology are the same as on Earth?

Thread 'Why does the amperage go real high if there is a low voltage short?'

I used to be an HVAC technician. One time I had a service call in which there was no power to the thermostat. The thermostat did not have power because the fuse in the air handler was blown. The fuse in the air handler was blown because there was a low voltage short. The rubber coating on one of the thermostat wires was chewed off by a rodent. The exposed metal in the thermostat wire was touching the metal cabinet of the air handler. This was a low voltage short. This low voltage...

Thread 'Electromagnet magnetic field issue'

Hi Guys We are a bunch a mechanical engineers trying to build a simple electromagnet. Our design is based on a very similar magnet. However, our version is about 10 times less magnetic and we are wondering why. Our coil has exactly same length, same number of layers and turns. What is possibly wrong? PIN and bracket are made of iron and are in electrical contact, exactly like the reference design. Any help will be appreciated. Thanks. edit: even same wire diameter and coil was wounded by a...
