My god.. This is definitely a nice PCB design What software did you use?

 

[luka]

LOL did you do that by yourself?
When I saw picture, my first guess was that this was pulled out of some "old" car amp. But if you did it, well hands down, best diy project I've seen in a long time


where is the problem?

The PCB design is like professional Japanese companies, left no spaces, well controlled track pour

about PCB!!

Uploading pictures, well that is easy

Go HERE and register, username, password..

Then upload picture with big blue "Choose Files"

What so that they upload, you will see progress

then you have 3 links to each picture/video

Direct link - if for say forums, so that user clicks on link like this >> www.dfaj... and it opens picture

HTML code - If you have your own page, this could be something you could use, not usefull for forums

IMG code - This is the one you want, post picture on forum directly



Note that your picture will be < 1024x768, you can choose smaller too.


For PCB, you should save it in PDF, so image will be 1:1, so other can try build it themself if you want that
