So the Bluetooth to inflatables work - yayee but I’m not sure what connector to put on (at the moment cable ties which keep it airtight but need to be able to able to undo easily). I need to be able to change the inflatables (currently balloons!) or let the air out easily.
Anyone have ideas ? of a type of hose clamp (though still very fiddly ) ? Or 3d print something ?
You might be able to get by with hose clamps sometimes also called jubilee clips. You’ll probably be best to line the inside of the clip with some rubber as the balloons are likely more fragile than hosepipe…
How about something similar to the old fashioned cardboard balloon pumps? They had small hole just big enough to get the end of the balloon in and I think they had a lightweight washer inside that would push up and form a seal / clamp the balloon in place when put under pressure…
