PCB ASSISTANT LAMINATOR CONTROL:  To make smart looking PCB's, all you need is: A computer, a laser printer, copper clad board, etchant,  A3/A4 laminating machine  and some  glossy photo paper. You can buy special film for making PCB's, but I have found that the  glossy  paper gives better results. I use photo quality glossy paper for inkjet printers. I got an  A3/A4 laminating machine for about $40(N 8000) in the computer store last week, for my sine wave mother board production, and i needed to produce a total sum of 50 pcs control boards for a new consumer of mine... then, i got tried of the forward and the reverse of a single control board for about 25 times  to get it done... well, i was able to press about 12pcs  in 2 days... then i taught of making a pcb  assistant laminator control  with a lcd display... Use a  laser printer  to print the image on the glossy side of the photo paper. Clean the copper ...

Here I present the stabilizer circuit of the IC 78XX and 79XX commonly used for voltage stabilization with a mini PCB design , and practical. In the picture above is looking from top the PCB, with a width of 2 cm and 5 cm height. For input voltage can be directly through the AC because i've put it four rectifier diodes are then forwarded to the Elco and IC , that has a stable output in accordance with IC series. What if the IC series 7805 and 7905 , the output voltage of 5 Volts. If the series IC 7812 and 7912 then the output voltage of 12 volts , and so on. See circuit schematic below : Part List : D1,D2,D3,D4 = 1N4007 C1,C2             = 1000 uF/50V C3,C4             = 470 uF/50V IC1                 = 78xx series IC2            ...
