But my main question is if it’s possible to create your own bitcoin miner and I’ve seen raspberry pi’s and usb sticks turned into miners but could a proper miner be made, obviously not to compete against modern consumer based miners but just enough to make a buck or two.
Note: I have a 3d printer and i tinker with tech in my spare time and though this might be a cool project to try out for fun let me know if there’s any info on projects similar to this or someone else is actually already developing this!!
You should have a look on this project : https://github.com/skot/bitaxe
Here is the topic dedicated to the project Bitaxe on Bitcointalk: https://bitcointalksearch.org/topic/--5400851
Bitaxe was created by Skot. which is an active member of this forum, and very helpful. You could join his Discord server, a lot of people are on it to talk about and discuss DIY Bitcoin ASICs
But as you can imagine, you won't be able to compete with companies in the sector with this. It's more of a hobby project than something to do if you're looking for absolute efficiency. Consider it a DIY alternative to the ASICs produced by Gekkoscience, for example.
