Then I got to thinking: the screw was metal, the top plates were metal… why not try to make the screw into a cap touch side button? I then had the idea of putting the screw on the side, but since the only place it could reasonably go was where the side button was. On my other models I use a single screw through the bottom to lock the sliding mechanism, but that wouldn’t work on this model since the screws I use are longer than the keypad is tall.
The second challenge was that once the design was mostly finished, how would the two halves lock together? I purposely made the halves slide together very snugly, but that’s not enough to keep it from accidentally sliding apart. It was actually a pretty easy design change to get it just as tall as it needed to be to fit all of the components inside. Since this model isn’t using switches, I was able to reduce the height of the top of the case by quite a bit since I didn’t need to accommodate for the bottom halves of the switches being on the inside of the case. Ideally, all of my keypads would be as slim as possible for ergonomics so you don’t need to bend your wrist as much, so I first tried to rearrange where the parts went internally. Since it worked, I looked at the whole model and thought about how best to optimize it. For the initial prototype, I just glued the metal plates to the top of one of my regular keypads to test the concept. The first thing I wanted to figure out was how I wanted to model the case. This is really useful for me since I don’t want to either make room inside of the housing for passive components nor do I want to use a PCB since that would complicate things even more, so this does a great job of keeping everything nice and simple. All you need to do is touch or connect the pin to another piece of conductive material using a wire and you’re good to go. It’s actually using a technology built into the ATSAMD21 called Q-Touch that eliminates the need for any external components. I was having a fun evening reading through the Trinket M0’s documentation when I noticed that it said three of the pins support capacitive touch. I’ve also been trying to play more osu! lately and I took for granted how nice it is to be able to play a rhythm game and not wake up the neighbors. Since getting the extra parts I needed for this newer design didn’t cost me too much, I figured why not give it another go after getting so used to touch controls on my phone. I didn’t put a whole lot of effort into that prototype (it was on a breadboard) and it was using cap touch PCBs that kind of sucked, so I wrote it off at the time. I actually tried making a cap touch keypad years ago (it should be somewhere in the osu thread) because I live in an apartment so noise is a bit of an issue, and I slam down on my keypad like my fingers weigh 50 lbs each.
Thnikk osu keypad issue free#
They are all free, have new songs added once every 1-2 weeks, and they all have gatchas that definitely don’t prey on people’s psychological weaknesses at all! I think these games are actually pretty similar to osu in that they are free and have frequent new songs, with more quality over quantity and less of being in a legal grey area (minus the gatchas.) It’s a long story of a long road to get to that point, mostly involving me being tired of feeling like every paid rhythm game was $60, required a special controller for another $40-130, had a few extra songs as paid DLC that were ridiculously overpriced, and then were abandoned (I’m looking at you, SEGA.) Playing games like CGSS and Garupa felt like a breath of fresh air. It’s the Touch osu! Keypad!įor the past year, I’ve been really into mobile rhythm games. Everyone give a nice, warm welcome to the newest addition to the keypad family, the 7K– sorry not yet.
