I dont think that this is a good Idea.... 1st: > in the October 1995 edition of ANSI/TIA/EIA-568-A: > > "The amount of untwisting in a pair as a result of termination to > connecting hardware shall be no greater than 13 mm (0.5 in.) for > category 5 cables, and no greater than 25 mm (1.0 in.) for *category 4 > cables*." Thats for CAT4 max data rate of 16 Mbit/s and performance of up to 20 MHz! Cat5e cables must be a least 45 cm long otherwise you have massive drop outs and other nice failures! We checked that with some High End Fluke Cable Testers - and no that no audiophile Humbug translated to Ethernet. Why using an [untwisted] Ethernet Cable to power a Pi over POE (and which device Powers the POE?) Really thats Nonsense and no not all Kickstarter Projects are made from a Genius.
