Well, that's it, we're screwed. My 3-kangaroo C program also runs on Raspberry Pi. I also have it an Android app with native JNI bindings to it. So every time I wake it up it runs a few batches to mine DPs. Next step is to implement kang on mobile GPUs using Vulkan.
I'm now looking for a place to rent ASICs where I can run custom software. However, there are firmware restrictions. Most ASICs, such as those from Bitmain (Antminer) or MicroBT (Whatsminer), come with firmware that may limit the ability to install custom software.
