Thank you for the compliment !
My point of view is that some ideas seem really stupid when you get them. Then 0,00001% of them change to genial invention… even if on this one I’m quite certain to stay in the 99,99999 % category
For the gap thing, of course this would matter… that’s why I wanted to control the beam position by myself.
Actually, I learnt about prerecorded tracks on blank CDRs helping beam positionning servos only after having had my etching idea I guess I’ll have to do some severe modifications to the hardware if I want to have the beam to go where I want, ie not following this spiral track. I guess the way to go would be to use some more sensors, as it’s done with lightscribe technology.
I also heard some people telling me a burner’s beam hasnt a chance to even scratch a layer of copper. Well, that why I’m more and more conviced this crazy idea will just stay in the 9,99999 % (if somebody thinks this is untrue, just let me know!).
But hey, laser pcb etching is soooo interesting that I’ll think about this but… more from scratch if a CD burner cannot achieve this. I saw some homemade CO2 laser designs, I guess that’s the way to go (but then it’s really off topic here).
Nonetheless… I’m still interested in precise burner informations, but for other purposes. I read some things about copy protection, and it seems that there’s things to do for a hardware guy like me in this field. I’d be really interested in having homebrew software booting on a console from a cdr without having to use modchip or exploits.
As an electronician involved in chip design and processors things (I work on compilation and design tools as a PhD student) I’ve always been impressed by the ps2 hardware. Recently, a coworker told me he was playing with its console, and we talked about how to have it boot our code ; we thought about some bootchip modification (that is, try to make an open hardware modchip and manage the boot process ourself).
For sure, the idea of being able to make CDR directly bootable on a console (even if those are just PSX ones) seems to be a really smart way to have our software booting. Well… at the moment I definitively have many things to learn about CDs and so on before being able to understand precisely what has to be done to achieve this. I’m really new to your community, and reading many things, but I hope I’ll be able to contribute So feel free to post any comment and/or contact me by pm if you always dreamt of an hardware guy wasting some time on some problems
I guess it would be better to start another topic, coz what I’m talking about here is very different from the original discution, but… I’m sure I’ll have some clever question to ask after having read what’s already available here and there (at the moment I’d be more like asking noob questions )
