Hey guys , Just wanna share the Cheep Power supply I made using an old SMPS laying around,
Can anyone suggest some more hacking to it 
Or may some of community members might have made one themselves, care to share 
Regards,
GS Gill

Using the Coarse + Fine Control circuit in my new Dual Bench Supply
Oh No! Not another #@&%# Power Supply
and since it was so easy to follow ... I made did this one.
(BTW John it's been very handy)
I used the case from a computer supply
The cooling fan is controlled by a Digispark clone reading a DS8B20 temperature sensor and switching the relay.
Dallas 18B20 poked into the cooling fins behind the output control transistor
Schematic overview.
Note the current meter goes in the negative lead to allow much greater voltages to be monitored.
Cheers
