hardware

You may not publish the projects on your website or any other medium; they are for personal use only. You are not allowed to use them commercially (unless stated otherwise).
Many details are missing. I have too little spare time to label all pull-ups as '10k' and decoupling capacitors as '100nF'. And no, I can't help you with such general questions. Unless you have a specific problem (like a misbehaving component or trouble understating some part of the datasheet) you are on your own.
Some projects are incomplete. I can't help that.
Some documentation is written in Polish. I can't help that either (although you can try to convince me to translate it for you).
I take no responsibility for the consequences of using my schematics, etc. If you mess something up, it's your fault.
