First post of mine so please bear with me.
AC/DC adapter that came with my WiFi router got busted and I am in need of one. I could go get the replacement but I am looking for alternative solutions. I have computer power supply that is gathering dust. I could simply tap 3.3 V from there. Since my current requirement is around 1 Amp max, that wouldn't be a problem. But the cooling fan's noise bugs me.
Other alternative is to get 3.3 V from automotive battery. That way I won't have to worry about router turning off during power outage. However, getting 3.3 V for 1 Amp current doesn't sound like a easy task.
Sorry if this question has been already answered. I would appreciate to get some pointer for building an affordable (should cost less than $20) PSU for 3.3 V. Or should I simply stick with free solution of using computer power supply?
Thanks in advance.
