usb miner project

[LGHustle]

Hello from Tampa.  Can someone point me to (or at least list) the asic miners (block erupter, futurebit, gekko science, avalon, ttbit) that are open source or have schematics or a data sheet.  I want to use the schematics in a elementary classroom setting.  Special interest on the antminer, block erupter and gekkoscience tupac and newpac.   Big thanks in advance for this one. I've actually searched the thread and the internet for a few days before posing this question.
