Hey there, this seemed like the best place to post some projects I have been working on that last year. Using older 80gb 5th gen ipods I added a 3.7v 8000mah battery with a few easy to find parts and a 2tb seagate external 2.5 inch harddrive. Going to post the build soon after I sit down and photograph the steps and post the stl files for anyone interesting in trying to make there own as well as I have a few completed and cases printed for sale. I can get 60 hours if I just let it run non stop and about 40 hours casual use. I only charge it once a week. It only seems to work with beyond winds msata patch installed for rockbox otherwise I get ata error-32 but original firmware installs ok. Much cheaper then the msata mod but with this bulky design gives you a chance to play around with a design and easy to replace everything. Here is a steampunk style I have made for myself, with wood frame and 3D printed parts painted brass. Might ask why, I say why not haha well enjoy and hope to see other people's version of this soon. I've upgraded the battery since taking this picture. Just took 2 months for delivery of the 8000mah battery's. First prototype. Ugly as sin but it worked. Second Version so I could keep it with me to see how it ran and battery performance. This is the design I finished with that's as compact as I can get it with easy to find parts. I have 2 designs, one for the thin harddrive and the thicker 2tb if someone cant find the other but its just a thicker back so easy to upgrade.
