MogLite Posted December 5, 2006 Share Posted December 5, 2006 There are some neat LED voltmeters on eBay However they appear to need a 5v supply to drive them. Is there a real easy/cheap way to get 5V from 12V ? I guess I only need a few milliamps to drive the voltmeter Quote Link to comment Share on other sites More sharing options...

Mark90 Posted December 5, 2006 Share Posted December 5, 2006 Why not use one of the other models that they sell which use a 5-15V power supply? Quote Link to comment Share on other sites More sharing options...
MogLite Posted December 5, 2006 Author Share Posted December 5, 2006 I've now learned a bit about electronics which is good. But if I comprimise my colour choice from green to blue, I can take Mark90's advice and just plug it in Comprimise on colour - NEVER Quote Link to comment Share on other sites More sharing options...

istruggle2gate11 Posted December 5, 2006 Share Posted December 5, 2006 see this thread The plug n play option is obviously easier, but Lukes response on the thread above worked great for me. But your auction man also sells them Here Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted December 6, 2006 Share Posted December 6, 2006 Andy, whatever it needs I can sort it for you, could graft a small regulator IC onto the back of one of those so it was only the battery supply and ground to connect up.
