hi all
a new idea for easy and fast etching
hmm, sry but i can just see a 3 sec video with no infos on it.
1 take one of those plates you can find in ovens or any metal plate
2 place a clothes iron (on) on top of it ant let it warm up
3 take a tupperware box (plastic) with top (lid?) and tape to it your dremel and use any T shaped piece of metal (i used a small screw with T hook
4 prepare your etching chemicals and pour them into the box with the PCB, tape the box to the metal board and start the dremel at minimum rpm
it took 6 minutes to etch an 11 X 11 cm double sided pcb
