The only thing I don't have at home is the UV light and a good laser printer. Anyway, that problem is solved by using the college's printer and the lab's UV light emitter.
So, at home I basically mix my own developer with water (using some basic judgment) I throw in my whole board and start shaking it for a minute and Poof.... There comes out the board with all the lines drawn =)
Developed board.Next will be the etching session. Now, here is the problem.. My friend told me that they bought for me the liquid Ferric Chloride but when I opened it up, it seems to have DRIED UP!!!
I was like OMG!!! HOW??? This is when i start korek-ing some of the powders into the container and it look excatly fine grained lead.
Ferric Chloride in powder form

Ferric Chloride in powder formIt is than i need to mix it with 60 Celcius water to it and i was like wondering how much water to add in order not to make it too dilute. Again i just simply judge and pour water into it. =D
When the water touches the powder, you can hear the sizzling sound coming out. That's when i lift up the ice cream box to check weather the acid got corrode and create a hole in the container =)
Looks like a galaxy full of stars
After that, throw the whole board into it and start SHAKING.
Shake and shake and shake for 10 minutes till my hand is tired and i just leave it there hoping the chemical can just do its job by removing the copper in the board while i go facebook. Somehow, after another 20 minutes, i returned and checked on the board, it gives me ZERO progress from where i left it.
Thats when i decide to continue shake it again. After 5 minutes..... still not done.

Picked up the board from the acid and wash the board till its clean and start drilling holes, putting the labels at the top, soldering and finally....
Tadaaa
TadaaaThe circuit was done. At the moment the board haven't gone through any testing yet. Therefore I dunno if anything goes wrong during the process =P
If you were to ask me what happen to the developer and the acid mixture... Well, after checking back at the developer bottle, i seem to had mix quite a lot of it. Therefore, i kept it back in a bottle and gonna reuse it in the future.
It changed to a beautiful blue
As for the Ferric Chloride...... I am not an environmental friendly engineering student =D
