Hi,
With the help of this forum I put a USB plug on my motorcycle using an 7805 with a 10uf cap on the 12v side and a 1uf cap on the 5v side. It works great for running my GPS and Ipod. So great that I have some people that want me to make them one too.
What would happen if a 7805 fails? Does it fail safe? Or is it going to send 12-18v to the device? Any other thing I would need to worry about. Some of the people I know but most are people that seen it in a forum that I don't know.
My first idea was to just sell a kit with all the parts and let them solder it. But a few wanted me to solder it for them.
Here is what I have.
My plan was to put some hear shrink over the 7805 and caps put some silicone in the two ends and then shrink. I have not noticed mine getting warm but it has been cold when I have been tiring it. Most will be going on dirt bikes so water is a problem. There should be plenty of air flow to help keep them cool.
Thanks for any advice.
PS I'm not looking to start a business here, just make a few bucks to fund the hobby, and to give me something to do while I'm off work.
