Large 3pdt pushbutton footswitch - need source

[multi_s]

you dont have to use sliders. although i haven't seen what you are talking about. how about this, power up with button down = momentary possible, power up with button up = momentary disabled. or vice versa. whichever you think you'll use less? or is that too complex. no additional parts needed. Also im not sure if i expressed the idea correctly. Its not always momentary or always latched. its both. ie if the tap is less than some time t0, its considered a tap and you change the latch. however if after changing the latch, the mcu sees the button is still down for some time longer than t0 then its considered a hold and also flips the latch on release. you cover all 3 cases , latching momentary on and off all at once. the action is to toggle, not to go to absolute states. You coudl use a trimmer or just choose a particular resistor value when building to set the t0 time. I dont really like the trimmer because now my pcb will cost 63 cents instead of 48.

just 3 solder pads to go to a spdt ON-OFF-ON is all it needs. all that dual function stuff is probably lost on most end users. not that they dont get it but they wont use it. if the pcb has that toggle, it can be on internal dip switches or case mounted toggle. I would actually mount the dip switches on the board though. thats just an option for the builder to do off board. if the middle position of the toggle switch is no connection then no connection on the board should = latching mode. then its super simple for anyone not using the fancy stuff but it only takes 3 pads on the pcb.

yes but if you have the ability to change the latching mode without opening the pedal = better and less parts+ less pcb surface area = cheaper. so to me the power on switching is better although that could be subjective. I mean really having to open the pedal to switch the mode seems like a pain in the ass.

to me the momentary thing is super intuitive. if you want to turn on or off your pedal your just going to step on it and release naturally. in your head if you want it on or off for a momentary time you will just step on it and hold. it will work like how you imagine it to do so.

plus if people cant figure that out they probably should not be picking up an instrument. no offence. on top of which it can be disabled easily, or maybe make jacks way the default. the smart mode can be used by smart people who are smart enough to remember to hold down the button on boot. i think it correlates nicely.

[eatyourguitar]

its like an invisible smart strip club with invisible women that only the smart people can hang out in

joking aside, I like your idea

[multi_s]

yes i am joking too. i should have put smart in quotations? if you are using the mcu you could use whatever setup you want anyways.

at 7 bucks a piece i think maybe its better to just make the design but not make apcb, instead have it so people can merge it on their own designs and stick it on the same pcb they are already fabbing (although i know not EVERYONE gets pro boards made) still seems like maybe more useful in terms of builders using it + way less wiring.

[eatyourguitar]

yeah that would cut costs and build times down a lot while keeping it all on one pcb. you dont have to sell it, you can just FSB it for karma. is the pic custom programmed for this application or is it an off the shelf part? sharing the schematic seems kinda funny if no one can get the special DIP8 thing.

[multi_s]

no, obviously you have to program them. a blank pic does nothing.

Use an electronic switching scheme (like the Deville kit) but add a large arcade machine switch in place of the smaller stomp switch. It will be a bigger target with a softer actuator pressure for your customer.

[eatyourguitar]

if he is using his hands then yeah. try videogamesnewyork.com or lizard lick amusements (lizardlick.com) for the sanwa OBSF30

Those switches would probably even stand up to foot use considering some of the pounding they get from hands. I bet they are better protected from dirt and liquids getting into the switch mechanism as well.

I'd also recommend elevator switches but they are extremely expensive and large.

[eatyourguitar]

they protect the switch from dirt but nothing is protecting the button from dirt. you can break them with your hands if you hit them hard enough. they are pretty solid but I would absolutely not recommend using your feet. the plunger on the switch inside the button is very small, much smaller than 30mm.

[whoismarykelly]

Im guessing that a kid mashing on a button with his fist is significantly more abuse than the average footswitch gets. There are probably metal arcade style switches that would be more than tough enough.

Not when you have a birth defect that prevents that.
This build is special case.

ordered some parts to test this out. if it works i will post the schem and i can send you a programmed chip.
