    You will need a set of needle files, there are some slightly off-square holes in there! As for the keys, I am either going to cut the acrylic so there is about 1/2 mm left on the bottom, or, just cut out 90% of the way around each key, leaving you to snap them off. I should have time to give it a go tomorrow :D

    It's good, and for what it cost to build, it's excellent. Unfortunately, it is slow. Machining with fast spindle speeds, such as with a router, requires an equally fast movement, especially on softer materials, to get a decent surface finnish. I ran mine flat out to cut this, and the result was that the MDF framework flexed a bit, causing some holes to come out slightly skewed. I could rectify it by either beefing up the structure (ie new cnc machine) or by using a slower spindle speed that would allow me to run the machine slower. However if I run the machine slower, you get greater heat build up within the cutter and the plastic. Problems either way, which is why a laser would be far superior.
    I just sent techTV a crispy tenner, so I think you'll win!
    Hyjnx, check your sig, then start dreaming!

    It might stand more chance of getting off the ground if you learn to spell. People might take you more seriously.

    aaaaaand with that...

    back on topic!!!

    ok i got the bl00 smt leds and the capacitors today... just one problem really, the LEDs are really not bright at all lol :) to be fair though they are immensly small (1mm * 1mm *2mm) there is also a fade.. but not much of one, only just quick enough to make it seem as if it hasn't been switched off...

    Malcs, maybe you should consider using the 3mm LEDs from www.lsdiodes.com then? They are only 3 times as big, and they can be sanded down to half size within seconds using a dremel.
    (Could still use smt capacitors, though).

    actually i have been playing around with some plexi and the traces, and when the smt LED is shining, it actually provides a nice blue glow around the keyswitch and then lights up the edges of the small plexi button... i like :D

    Boohoo :waah: I am not a god anymore!
    Back to reality I'm afraid, my machine is not quick enough to route acrylic. Even with coolant, here's all that happens:
    [​IMG]

    See that build-up around the cutter? Caused the machine moving too slow. You can either wait unti lthe completion of the uber router, or I can send you the acrylic for you to cut the keys out yourself. Sorry! :wallbash:

    Of course. I can do the bottom aswell, no probs if you want. Mind you, I'm out of polycarb, so I'll have to get some. Let me know. It really is amazing, the differences between acrylic and polycarbonate!
