I have a peltier element ( [login to view URL]) and 12 LEDs (1/4 Watt). I need a circuit that boosts the Peltier voltage and with an adjustable constant current driver to drive the LED array.
A reed switch should be used to turn on and off the circuit. The circuit board dimensions should be pretty small maybe 1 inch by 2 inches. I am looking for a circuit board design including schematic, BOM, and gerber files for board manufacturing. The parts should be common parts and newark part numbers are preferred.
Thanks
i have done simillar project.. i used to glow night lamp in summer, using out high temp(water tank) & inner room temp.. but mine was not cost effective, as glow of led was very low.
