I saw in another thread a regulated 5V power supply from Wellborn that looks the ticket for a DIY project I have in mind. I need to replace the wall wart for my Squeezebox 3( www.slimdevices.com), and would like to create a little PSU that gives 5V DC at up to 2A (The wellborn one seems to offer 1A) I need a minimum 1.2 A for the Squeezebox. The wallwart that comes with the Squeezebox 3 is a 5V Switching, and a number of peeps have posted good results with a linear version (which I assume is the Murrican term for regulated) - I'm not sure I understand the difference between switching/linear/regulated. I have in mind a power supply that takes a IEC kettle lead input from the mains (I have a spare socket on a filter that would support this, and ouputs through stadard pin connector (AKA Laptop power type connector - 2.5mm ID, 5.5mm OD, 11mm long) I cannot find anything off the shelf in this spec that is not a wallwart .. and even then I cannot find anything that gives up to 2 amps regulated/linear! That Wellbornlabs welbornelabs.com/psreg.htm would be perfect (I think) if it gave 2A! Can anyone help with off the shelf .. or something similar to the wellborn board - what else would be required apart from the obvious case IEC connectors and plug terminal.

Oh what a numpty I am .... there's a link from the low amp version to the high amp version. It even mentions the Squeezebox in their blurb!
Doh .... !!

not sure if I follow but if you are asking how to finish off project using the board you need a chassis,wire,.IEC outlet,fuse,DPDT AC rated high current power switch,mounting hardware,mains cord,some type of power on inicator (Neon,LED,Lighted Rocker switch,etc.) and triple out DC power connectors if this is to be an external device.No point in building it then not being able to use it with other devices if they too need a solid +5 VDC If you are asking how to build your own scratch version simple-the schematics are right there on the pages and i can if need be supply you with the parts list ;D
