Let's make a pocket sized Iron Box. Follow this steps carefully and don't miss any.
The softwood is best suited for this function. Cut the wood by the help of a hack saw blade referring to the same measurement as the one of aluminium sheet carved. Using fine sand paper, smooth the surface altogether with the edges of the wood. The thickness of the finished frame should be around 1 cm thick.
Components to fix on the frame;
Mark the area covered by the components. Use chisels to drill depressions where they’ll be placed.
From the wide collection of thermo electric cooler(TEC), select TEC-12706, to power it 5 v 1 a adapter. You may use up to 12 volts for this type of thermo-electric cooler. While varying voltage, change the value of the potentiometer with respect to the potential. Potentio-meter has a function of adjusting heat in the iron box. The Switch is meant to put on and off the device. The purpose of Power jack is meant to easy plug in. Put the order of the components in the bread board with respect to the diagram. Check to ascertain if it’s working or not.
The side of TEC that is feeling hot or heating, is the one you’ll fix to the base of the iron box.
All components remained should be installed into the frame using normal adhesive. Use male- to -male jumper wire to solder, you may as well use single strand wires.
