It’s been great to read everyone’s project ideas. Many of your ideas made me think of a couple of resources that could be useful for you:
Miriam Posner, coordinator of the Digital Humanities program at UCLA, wrote a great blog post last year called How Did They Make That? which features several different kinds of digital humanities projects and breaks down the technologies and steps required for each. It’s a good post for getting your head around what’s required for some of the DH projects out there online.
Bamboo DiRT is an enormous resource that’s essentially a database of digital tools for research and teaching. It’s organized by category (e.g. data collection, image editing, etc.) and each category features an annotated list of tools, both free and paid programs/apps. It’s also a great place to browse while you’re germinating project ideas.
