Forgive me since I am new to this space.

I am trying to build a remote controlled esp32 setup with a small battery pack (3.7V 1000mAh) and a 10mm x 3mm Coin vibrating motor that can be remotely controlled from a nearby computer. In speaking with friends, this seems feasible, but I am more concerned with the containment device.

I am most concerned with what to put this device in. I want it to be somewhat quiet and for it to go on my body. What sort of containment device would be best suited to do this without making a whole bunch of noise that's easily detectable? Thanks!

I’m trying to connect two physical keyboards to my PC, but I want Windows to see only one keyboard device. I tried a USB splitter (y splitter), but that did not work. From what I understand, a normal USB hub or USB switch may still expose the keyboards separately, or cause disconnect/reconnect events when switching.

What I’m looking for is some kind of device that can take two keyboard inputs and present them to the PC as one stable USB HID keyboard. I think this might be called HID emulation, keyboard/mouse emulation, a keyboard merger, or a USB HID proxy.

I do not need the keyboards to work as separate inputs. I just want the PC to receive keyboard input while ideally only recognizing one keyboard-like device.

Is there an affordable device that can do this? Would a KVM with keyboard/mouse emulation work, or would I need something more specific?
