Homebrew PCBs

Thanks everybody , here is a little more information

As both the developer and etchent were from the same company and in 
the same packaging I used an approximation like so:-

Etchent was in a 250 ml Bottle
Developer was in a 250mg Bottle

so knowing that a teaspoon is 5ml, roughly the same amoun of 
deveoper granuales on a teaspoon would be 5mg,

similar to this post

I used 500ml of water with a 10:1 ratio of developer so I would need 
50mg of granuales or 10 teaspoons as an approximation, however as

I also noted this so I only used 5 teaspoons (leveled not heaped to  
be on the safe side)

I did continuously keep the deveoper moving both by rocking and by 
moving a brush around the solution (not brushing the board, this did 
not come into contact with the board, just kept the solution moving)

hope that makes things a little clearer

Kind regards
