I 3D printed some AA to C battery adapters to use in my sons Nerf gun (which currently doesn’t work- I can forsee a post on this repair soon) as we have a supply of these because we use rechargeable batteries. I was asked the question “Do those really work in practice? Do you get any appreciable run time from AA’s in something that expects C’s?” to which the short answer is YES, and the long answer is below.
For Christmas my lovely wife got me an Oculus Rift S VR headset which I think is awesome. My kids also think it is awesome and as such I haven’t been able to get much time on it with them hogging it, so I got another second hand one hoping to simply plug it into an older computer with a leftover mining card. There was nothing simple about it.
