The problem was reflected in the electricity bill and I called Ginasena and they sent one of their tec...

Re: How to etch a PCB?

Here I have added a new method. See Another method to make a PCB at home with iron.

Note that you can use an iron instead of UV transfer method in the previous method.

Another method to make a PCB at home with iron

PCB OR a printed circuit board is a component made out of layers of insulating materials with electrical conductors. The insulator can be made of many materials mainly plastic, fibreglass and ceramics. During manufacture , the extra conductors that are not required are etched off, leaving printed ci...

Re: Simple SD Audio Player with an 8-pin IC

2. can we improve this to read usb flash drive?
You might be able to do that. But you'll have to write extra codes to handle USB interface, etc...
You can do all these with a single chip(without coding) from MAXIM. See USB to SD card interface IC.

Re: High Gain UHF Booster

The one added by Magneto is the best and the most commonly used one. Can you put some photos of the circuit board you made. Would like to have top and bottom view clearly. Without these, we can't trust that you made the right thing (or even made it at all ;) ). This is another one. c.png This is an ...
