    It’s an awfully warm summer here in southern Sweden and it’s too hot to sleep… did this last night…

    <movie>

    An attempt to make a smd version of CFA3. Same board size as the smd version of Dynahi I built some months ago.

    Lots of more work… doubt I’m capable to get this to work though.

    I am into this. I have been thinking about a CFA3 and an SMD version appeals to me a lot. Hope you can get it working!

  2. Finally got the output stage of my amp at least somewhat functioning. Spent a solid few weeks scratching my head and thinking I screwed something up. Nope, both 45 tubes I have had bad heaters. Bought another tube and now everything is as it should be. Next stop: find some output transformers.

  3. I finally got around to servicing my Sony PS-X7. The speed control was acting up by holding a speed but then jerking the table every couple of second.

    Found the service manual online, did a couple of the steps to adjust the speed controller and cleared the problem completely. Also learned a skill I never thought I would have to learn, how to wrap wires.

  4. 220V is also good for welding, surprisingly few have a 120V option. Which I why I ended up with an AHP.

    And Naaman, that is damn sexy. Did you do the modeling off of your badge yourself?

    I picked up an SMD practice kit since I have a few things I want to do that would require it. Tried hand-soldering for the fun of it. The results work, but are not worth the picture.

  5. I have not, though I probably will now. Feed and speeds are still a bit arcane to me. Easy enough for wood now. But I know the Shapeoko can do softer metals and I intend to do that soon. Even picked up a surplus fridge compressor to kit out as an air assist/mist cooler

  6. I goofed around enough in Gimp and Inkscape designing patches in the past to at least be mediocre at making vectors. And like both of you, just cautiously dipping my toes into 3D so far. The motivation problem I have is that if I do not have a project that requires it, I'm not going to really put effort into learning.

  7. Naaman, I've been using predominantly VCarve Desktop since all my work so far has been 2.5D designs. Kinda steep at $350 but it does make simple cutouts real easy. The Cub Scout plaques took me maybe 15 minutes to set up since I was able to easily import a vector file. There's a lot of community support so a G-code post-processor I bet has already been written for your specific machine/controller.

    The bad: the Desktop version only allows a 24x24" work area. Unlimited costs $700, which it looks like you'll need on your machine.

    I will say, having used my little diode laser add-on, it's good for space efficiency. But if you have the space for a whole other machine, I would say a standalone CO2 laser would be way nicer to use, and about the same price.

  8. Cutting has definitely been an uphill battle with a diode laser in my experience. I have not been paying attention to what rig you are running so I may be in a totally different court. Also Lightburn was worth every penny for laser work. $40 is nothing compared to some of the other CAD/CAM programs out there.

    Those cutouts look heckin dope! ....if you wouldn't mind sharing the vectors.....

    I've been doing Arrow of Light plaques for the local cub scout troop. I won't share the finished project because I feel weird sending out names of children but the arrow was cut out with the router then the words cut in with the laser. Arrow was then filled in with yellow paint and the whole thing was stained and varnished.

  9. The thing I have learned working with a lasers is you need to treat it like a weapon: is it loaded/plugged in, is it safed/armed, is it pointed at the thing I am going to shoot and not at the things I do not want to shoot, am I wearing the safety gear, is everyone else safe or with gear on, do I know what I am doing?

    Only then, do you press the button.

    Shitty day out here, trying to motivate myself to head out to the garage and put my words into actions.
