Competition definitely inspires savagery, doesn’t it? So what do you do when you need a bunch of switches push button that allow people to hit or stomp repeatedly without taking damage? You can go to guitar pedal manufacturers and their reliable detent touch switches push button, or you can just make your own shock protection buttons like [wannabemadsci] did.
The main feature of these switches push button is that they are not easily damaged by shoes or evil fists. That’s because the shiny red part of the “click me” button is made by cutting a Styrofoam ball in half.
Check out the less brittle Styrofoam – coated foam that is as soft as an indoor soccer ball. It is mounted on top of a cardboard sandwich and a few pieces of easy-to-squeeze foam from a paint brush.
A brass washer is placed between two pieces of hard cardboard, to which wires are soldered to read button presses. Then connect it to the microcontroller like any other transient.
You can cut various objects in half, such as tennis balls. Or, as [Sprite_TM] does, use an upside down plastic bowl.
GOOD Still not sure if it will last that long in the most hostile environments like schools or public areas – foam balls don’t seem to last that long.
I would probably go for something with no moving parts – a piece of cardboard with a piezo element underneath to detect the stomping noise. A few years ago, I had amazing success detecting table taps with two piezos – perhaps inspired by an old HAD article…
Well, there are those cars with sensors that tell the gas station that you need to refuel. It’s basically a rubber hose with a press sensor.
Oh yes, “Ding the hose”! One of my favorite second hand stores has a section that welcomes workers when you want to donate.
Cool concept, but I would also like to see it after a month of serious use. There’s also a lot of side loading if people stomp it, I don’t think the foam and glue and wires will hold it in place, I wonder which comes first.
On sale there are reset buttons that can be used to flush floor toilets. They withstood a fair amount of pedaling. It is a black elastic rubber with a pneumatic tube inside that triggers a flush when the user pinches it.
The Seacan container is supported by another container with a 3 block high briquette wall… each has hand-sized thick steel cables welded to…
I had to buy something similar for a working project. The only catch: for medical use, it must be completely isolated.
The solution is a rubber bulb like the one pictured above, but with a rubber hose leading to the press switch in the block. Absolutely no wires required, just a rubber dome and tube. Step on it and the waterproof switch in the device will activate.
In 2015, I made a mock quiz button system with giant semi-circular buttons. If I thought about it, I could save $50 of my budget.
