I have a great idea for an invention, but I am currently limited to purchasing parts for building a prototype of it with bitcoins. Unfortunately, I do not have that many bitcoins and need a way to ask the bitcoin community for donations. Yes, I have an address, I am not a newbie to bitcoin. I would like to know where I can ask for bitcoin for a scientific project that could benefit the world. If anyone is interested I will disclose some information about my project.
