So I have a 7812 Vreg without a 0.1uf cap the voltage regulator would heat up pretty fast within seconds, is it standard to put a 0.1uf cap on it regardless of length?
I built this SLA battery charger from here
http://shdesigns.org/gcellchg.html
to add a bit more to this I wanted to add a PWM motor controller which I have here (MIC502) and a voltage monitor to cut power from the battery when it falls under 12.4V (MAX8212)
being as the MIC502 has a max input voltage of 13.2V I have it on a 12V voltage regulator..
This whole project is a emergency lighting, as long as power is going to the SLA charger the lights will be off, but as soon as the power drops the lights would come on
attached is the battery monitor the PWM fan controller I don't think should be too hard to connect, I'm not too sure what size PCB I need.. the fan I will be using is a 12V .60A fan that is temp controlled.
If this sounds like a mash up of stuff it is, I took a break from the project for a few months to do some other stuff so I was wondering if any other improvements could be made and not to take much space up in the project box I have.
