AI Thread Summary
To trigger a capacitive touchscreen without human touch, the discussion explores using conductive materials like wires and batteries. The user has found that holding the negative pole of a battery or using the edge of a wire can activate the screen, but the effectiveness varies. Suggestions include experimenting with capacitors to see if they can replicate the touch effect. The user seeks specific guidance on materials and methods available at hardware stores, indicating a need for clear, practical advice. The conversation highlights the challenges of mimicking human touch with non-human objects.

I'm trying to trigger a human touch in a capacitive touchscreen without the 'human' part. I've noticed that the negative pole of a battery triggers it if you are currently holding it. Or if you use the edge - why only the edge? - of a wire touching the battery and your hand. I also attached a wire in a metal bottle and connected the battery to it's end (with the battery touching the screen) and it also worked - but sometimes it also didn't.

The question is: How can I trigger a touch on the screen without the human touch, using objects from the hardware store?

I have almost no physics knowledge for this, so you guys have to tell me exactly what to do (which material, where to buy and etc).

Thank you

Have you tried touching it with one lead of a capacitor?
 

Thread 'Underwater piezoelectric sensor array receive sensitivity'

Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...

Thread 'Following up on the recent thread about Earth Resistance measurements'

I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...

Thread 'Beauty of old electrical and measuring things, etc.'

Even as a kid, I saw beauty in old devices. That made me want to understand how they worked. I had lots of old things that I keep and now reviving. Old things need to work to see the beauty. Here's what I've done so far. Two views of the gadgets shelves and my small work space: Here's a close up look at the meters, gauges and other measuring things: This is what I think of as surface-mount electrical components and wiring. The components are very old and shows how...
