I see you must have done what I did and made an adapter rray. However i Want someway to go directly from the car battery to a 12v 2amp output. Any ideas anyone? I really dont want to burn up another one.
If your handy with a soldering iron you can get a decent heatsink,small amount of pcb a couple of diodes and a 7812ct voltage regulator the 7812 has 3 pins voltage in..ground and vol out.pretty easy and it will cope with 2amp with a decent heat sink....
Can do the same with a 7805 voltage reg for a stable 5v.these can be lined up in a project box so you can have 9-14v in and a stable 12v and 5v out...costs very little and a bit of fun
This is great. I am very handy with a soldering iron. Do you have a schematic?
The problem with using the 7812 is that if alternator/engine is not running, the battery does not provide enough power to work the 7812 properly, most regulators like this need a 2v overhead above the output so technically you need a constant 14v. I am in the same delema, I want to regulate for led lighting, very low draw but not enough input power. Just my 2 cents SNO
Good point Sno it really didn't think bout that.as mine goes on and off with the ingition....the 5v 7805 for my usb parts is happy.
