Enclosed ESP32 Based Game Controller

thingiverse

Hello all! I am once again back with another small project (I say that this is small but it still took me 3 months from start to finish to complete haha). As you might see, this is practically a clone of the Xbox One (?) controller. Its a bit of a cram as you might see in the second picture but it houses a TP4056 Battery charger-protector IC, some custom prototype board PCBs (They are not hard to make, also I am using tactile buttons here but silicone buttons should also work, I just didn't have them available) The main part of the show is the ESP32 dev board. You might ask why I didn't use the chip instead and to that I reply: I am not good at soldering or desoldering, this is just a side project and I used what I had. This is also exactly why I used shift registers instead of counters to drive all the 16 buttons using only 4 pins :D The ESP32 is not the most efficient IC ever but it gives 2-3 hours of battery life with the 330mAh LiPo cell I have in there (on a side note, I also managed to cram a 5V boost circuit behind the ESP32 board, since lower voltages interfered with the joysticks somehow) Another important note is that although this design is fully 3D Printable, I honestly am no perfect designer, and you might see many wrong things in my designs. To counter that I have also shared the STEP file for the project. You can tweak the design however you please! Thanks for reading till this sentence and have a nice day! - Omer Hasanov 2022
