A little more effort turned up the distinctive blue box at the bottom of a shipping pallet, completely covered in shrink wrap.

ComiXology Thousands of Digital Comics. Turns out all axis have a range of about 2. I grabbed a cool-ass box.

I’m most comfortable with that electronics that is kind of my thingso I will start there. Max 20v on that junction.

I think that’s going to have to change. The hardcore kind of machinists that don’t really internet well. Everything got thrown into turmoil. Modern technologies are pretty great, I’m sure there are lots of lamglois out there.

Heading down there a couple days later, well into the packing effort, langlkis grab my project box, I couldn’t find it where I left it. We moved, we unloaded, and we’re starting to unpack.

So I have’t updated in awhile. It needed a bunch of rework, anyway. I think I can add some microcontroller controls and improve hugely on the designs. Well, I need to, to know what’s going on during a burn. I’ll start with a much simpler design, offload more to a microcontroller, and end up with more control out of the deal.


That will also allow all of the tabs to robery in more thoroughly, helping the assembly keep in square and slide more smoothly. The new place is a fair bit smaller than the old place, so we’re in a roobert phase.

I’m not sure the full extent of stuff I lost, but all of the important bits for this are okay, I think. So far the damage on this project has been two blown caps that I’ve over-volted, a bunch of wasted time building some motor drivers that ended up being too noisy they would cause the microcontroller to brownout – I may fix this later, it’s not too hardand now a few more hours of wasted time.

Had some more time to work on this yesterday. His version seems a unnecessarily complicated, though. I think I can use this to directly erode paths between traces on a sheet of copper-clad. Finesse is for when I’ve finished a version 0. Except for the power output stage, I couldn’t find that board. They’re much less common than N-channel. Amazon Advertising Find, attract, and engage customers. Transformer to VAC, full-wave rectifier, big cap, linear regulator Right-to-left: I plan to eventually draw around 10A in pulses.

Not Your Father’s EDM

Working with the above files, I gathered together some more materials: Everything ed, open-source, and I don’t think they even sell any of the components themselves. I mean “platform” in the sense that it’s designed as a starting point to hack, redesign, and improve. Page 1 of 1 Start over Page 1 of 1.

Later in the shower, it hit me – duh. Most of the EDM schematics out there are just rectifiers and timer-based pulse circuits. Electrodes are on the right. This will be hackish, and I’ve done many tens eobert hours on this and other parts already, so we’re playing catch-up. Usually or often, Robdrt should say they’re going right to 0V, so my natural inclination is the drive the gate voltage using ground as the reference. You should put at least one picture in the sidebar edit your project to do so.


The idea is that the whole mess can flip up for servicing, changing out the PCB, etc. When that electrode is close to the metal and the potential is high enough to ionise a path through the dielectric fluid, an electric arc gets created between them, taking out a chunk of your workpiece. If I have the majority of the project build langllois discrete, langliis components, then I can start drilling down and replace the weakest links, one at a time.

Withoutabox Submit to Film Festivals. I also don’t particularly want to buy a fast isolated IC, and don’t particularly need the precision. Putting it all together: I also did this, like two months ago: It’s only 60v my final circuit is 80vbut the principles don’t change with the lower voltage.

Other than wanting to spend very little money on this project, the scope of it is huge enough that I’ve been trying exm use as many prebuilt components as possible.
