I read this is the standard to be able to analyze what you really made. If you read my other page you will realise I know nothing. But of course, a proper chemist will have to be able to assay things. So, if you have any information on building them you can point me to please do.
This is something I'd really like for everyone to be able to have. A few other pieces of equipment too we can build almost from scratch. My dream is the project I create allows you to walk out into world and make everything, from world. Big too dream, but lets get a start on the bits we can do.
