20:5920:59, 23 February 2011 diff hist −64 Power over Ethernet removed "pses classify as class 0". Seems to be incorrect. See discussion.
20:5520:55, 23 February 2011 diff hist +2 Power over Ethernet fixed pse detection resistance "correct" range

23:0923:09, 18 February 2011 diff hist +209 User talk:Dicklyon No edit summary
22:0222:02, 18 February 2011 diff hist +161 Power over Ethernet added a few words on how power is supplied in preview.
21:4521:45, 18 February 2011 diff hist −71 Power over Ethernet removed request for clarification: classification probe voltage can be anywhere in that range, that's why 15.5V works.
21:4221:42, 18 February 2011 diff hist +10 Power over Ethernet forgot IEEE before standard number.
21:4121:41, 18 February 2011 diff hist +188 Power over Ethernet fixed >= sign and reference pointer i broke earlier
21:3721:37, 18 February 2011 diff hist +234 Power over Ethernet fixed startup voltages and operating voltage ranges to match those in standard. included references.
20:3820:38, 18 February 2011 diff hist −79 Power over Ethernet removed wattage spec in powered device...it's mentioned *plenty* of times elsewhere. This is just defining what a powered device is.
20:3420:34, 18 February 2011 diff hist +490 Talk:Power over Ethernet pse classify as class 0??
20:3020:30, 18 February 2011 diff hist +61 Power over Ethernet →Powering devices: made class 4 work for af and at with explanation and reference under table.
20:0220:02, 18 February 2011 diff hist +81 Power over Ethernet →Powered device: changed wording, clarified auxiliary power draw, included references.

17:1617:16, 3 January 2011 diff hist +18 Zener diode Regulation explanation is false unless voltage source is current limited. Claiming that internal resistance will regulate it is silly.
17:1317:13, 3 January 2011 diff hist +19 Zener diode Added why conventional diode gets damaged if current isn't limited. No need for guessing.
17:1317:13, 3 January 2011 diff hist −38 Zener diode Undid revision 405713297 by 70.133.83.60 (talk)
17:1217:12, 3 January 2011 diff hist +38 Zener diode added few words saying WHY conventional diode gets damaged. no need to leave guessing.

20:5220:52, 3 September 2010 diff hist −1 Talk:Laplace transform typo in comment
20:5020:50, 3 September 2010 diff hist +237 Talk:Laplace transform Suggest adding transforms used in examples to the transforms table.
