Re: [Homebrew_PCBs] Direct Toner - Challenge

Hi Stefan,

I'm not sure whether I am actually interested in a commercial venture 
- I have more than enough to do right now - but I am interested in 
considering it. I haven't really done much with the process so far, 
but I'll try and do more in the next few days. If it has commercial 
viability, it would be only as a prototyping system, not for 
production. It certainly seems much better and faster than the cnc 
board mills that go for thousands of dollars.

My approach to things of this sort tends to be empirical - try it and 
see what happens - rather than look at whether it can be done from a 
theoretical point of view. You'd be surprised how often things that 
"can't be done" really can!  Here is a link to my other products - 
they are "out of the box" type products, as well. <http://www.markkenny.com>.

I'll be happy to answer and questions that you might have. I'm tied 
up for the moment, but I'll try to go through what I did in a step by 
step fashion so that it can be repeated. I can do it on the web site 
or in this forum - any preferences?

Mark
