 These are some cool clicky buttons. JP our resident synth fan and drum machine collector was like hey you know can you get some of those switches that you see in some drum machines or synthesizers or keyboards that have a kind of nice clicky tactile switch and a built-in LED. So I got this sample I just soldered it up to a breadboard so when I press the button the LED lights up. The LED is independent from the switch but I just wired it so that it turns on when I click it and I got this with black and red LED gray with rally and red with red LED. So I think this is a good start. Well we're coming a couple of packs since they're fairly inexpensive and then we'll make a package for them in EagleCAD so folks can DIY their own 808. These are knurled knobs you can tell they're knobs because they're round and they've got a cool pointer I like that the silver one has a black paint pointer the other colors have white paint so it has a good contrast and the side are knurled you can see the machining effect makes them really fun to grip onto and twist on your synthesizer or drum machine and these come with a set screw so you can see here the set screw I've been testing it out with a two millimeter hex wrench and the set screws nice because it means you can use D shaft right so you get a classic D shaft potentiometer or rotary encoders and you can twist just by pressing it in and then setting the set screw or if you have a T18 or round shaft knob you can press fit it in and then also use the set screw to set it so these work with any kind of potentiometer or rotary encoder coming soon to the Adafruit shop and that's top secret okie-dokie
