Here is my implementation of Gert's VGA board for Raspberry PI B+.

I was looking forward to testing one and I could not wait the delivery of an official PCB. So I decided to build it myself.

Here is the result.

I am quite lucky, there are already some shops in my town where I can buy electronic components in person. E-commerce is nice, but I prefer to ride my bike, get the components I need in a real shop as if I were buying food or stationery, and return home to solder them.

Some of the resistors listed in Gert's schematics are not available the EIA96 standard (4K 8K and 16K) so they are not available. It is possible to use similar values like: 4.02K 8.06K and 16.2K.

I decided to use only three resistor values 1K, 2K and 16.2K. I was told that these value are quite common, at least these are in the subset of E96 values normally available at my favourite supplier (Arduini Elettronica, Casalecchio).
