I have a 12vac 3 amp transformer and I need to get 24v from the transformer for a project - variable power supply.
There's a cheap kit from yes you guessed it China but it requires 24vac.
Now I know your going to say why not just buy the appropriate transformer but iv not got the money, I have been tempted to use an old laptop charger and ?hack? to increase the voltage to 24v and bypass the bridge rectifier on the power supply kit.
This is the kit I'm working with

I know it's cheap and cheerful but Im making do with what I can afford. And there's a lot of mods people have made to this kit for better results.
Iv got a shed full of salvaged pcb full of components which I reuse.
Any help would be much appreciated
