  1. RTJ hands fixed Honestly, I'm pretty psyched with how these came out and they were a great test bed for figuring out how to accurately combine/sequence engraving and cutting. Now for a light sanding and finishing and then delivery to their owner.

  4. Now if you could just change the one on the left to fold in the index finger, and then point it toward the Whitehouse. Seriously though, nice work!

  8. I'm surprised someone hasn't posted about lighting up the bong tonight. This would be the day for it. Pardon me if the bong is not still in fashion. I haven't kept up with these things.

  9. To see what and how to improve, let's have a look at the original schematic. KSA-5 is designed along the lines of "moderate feedback", that is, it uses very little to no global feedback but lots of local feedback a.k.a degeneration. The pair of input JFET buffers (Q1, red box on the schematic above) run independently of each other and outside of the global feedback loop. With low loop gain, they see very different signal levels, so the differential stage downstream doesn't cancel their distortion. (BTW, because of this JFETs need not be matched. Also, the expensive and hard-to-

  10. Let me first modify the output stage. The mod affects only the performance with lower impedance loads, and even there it can take us only so far, but it is a start. The front end modification that increases the feedback loop gain will be posted separately. The changes are simple. Here is the schematic: R33-R36 are replaced with 0.22ohm 3W resistors, R19 is reduced to 470..560ohm to allow proper biasing, and R37-R38 are replaced by a single 47..51ohm resistor. The bias will need to be re-adjusted. Note that 50mA per transistor that resulted in 100mV between the test points in t

  15. Thank you, I’m kind of also coming to the conclusion I need to learn Illistrator or Inkscape for vector creation. Like guitar, wish I would have picked some of these things up years ago.

  16. I’ve already purchase VCarve Pro and have been learning to use it, seems pretty easy for most tasks. There is a post processor for my machine so it all should (hopefully) work well. I’m also working through Fusion and putting my head into the parametric modeling mindset since I know it’s probably the best thing for long term 3D design. So much to learn, so little time.

  17. Tab "Hunter." I brought him to the vet because he had a nasty cough, almost like whooping cough. We got the devastating news that he has lung cancer, and it could be as little as one week left. Four months later (!) still has the cough, and spits up sometimes because of it. But he loves being with me, purrs up a storm when being pet or brushed, eats and drinks regularly, etc. Is definitely breathing shallower and faster, and pretty much sleeps a lot when not hanging with me. But still great company, and he hasn't told us it's time yet.
