that membrane crap.
According to the discussion: That "membrane crap" is there to keep finger-dirt out when it's used in dirty environments and so that people can sterilize the keypad easily with anti-COVID wipes.
(this was designed during COVID times and we're not the target demographic)
it is still crap to me. i want tactile feedback ! Membrane could work if they put in a haptic driver . then again. membrane i so outdated. you have a touch screen. They should have made it capsense !
My gripes with membrane
- no tactile feedback
- membranes invariably fail. the patterning oxidizes, shorts out or opens.
- the top foil hardens and cracks / splits/peels over time. go take a look at your average membrane keyboard used in fuel pumps.
- they are glued on from the outside which makes them VERY hard to replace.
- if they are used with tactiles underneath the plunger of the actual button starts making indentations in the membrane . splitting / peeling unsightlyness.
- domed tactiles are even more prone to cracks with the dome falling off
- Once the membrane integrity is damaged moisture gets in with disaster results.
use a membrane foil with a rubber key overlay. those rubber mats are easily replaceable. i don't care about covid wipedowns. it's my scope on my bench in my lab. nobody else fingerpokes it
if this is targeted as a handheld , drag into the field. i could live with it. but then they show a fancy bench stand and tout vesa mounting. what is it ? what are we targeting ? handheld , or wall mount ?
another thing that irks me is that there is no tekprobe interface. can't use any active diff or active probe... that's a bit of a bummer. all that is needed is the contact foil and some regulators and an i2c bus.
