Build an EDM Machine (2 Book Set): Robert P. Langlois Ben Fleming: : Books

I’ll start with a much simpler design, offload more to a microcontroller, and end up with more control out of the deal. A little while later, I rkbert a frantic text message, “Pick up your shit! There is a decent chance that the sparking from my electrodes will cause enough interference to mess with my servos.

The transistor’s max pulsed current is 12A, which is great I plan on using 4Abut while I am technically doing pulses, it will be repetitive and ddm high duty cycle as my mechanical system will allow.

It alnglois stuff in it, but after I took that out, there’s plenty of room for me to put all my electronics crap into. Electrodes are on the right. Otherwise when this shows up in the project list there are no images. PIC18F microcontroller one I had kicking around, a very beefy model ten years agodual 7-seg display that is no longer connected and I haven’t finished desolder yet, a row of serial-to-parallel shift registers to drive LED displays in their new location, a row of not-fully-connected 2N BJTs for motor drivers.


Basically when the electrodes get close enough with a high enough potential, then an arc gets created, ionizing the path between them. If you need a square hole, or other unique shape in a part make a square electrode and burn it into the part.

As you can tell, I’m just plowing on roberrt building things for this project. The power bit is the hard, industrial-trade-secret type thing that makes electrodes spark. That is made more difficult by the hackspace being in a state of flux buiild the moment after having our lease unexpectedly terminate recently. As it stands, I have a clean 5v rail and a dirty 80v rail. The rails came from a salvaged scanner, and I have the bushings, they’re just encased in plastic and I haven’t taken them out yet.

I also don’t particularly want to buy a fast isolated IC, and don’t particularly need the precision. Similar Projects The Hackaday Prize. Most of the EDM schematics out there are just rectifiers and timer-based pulse circuits. This will be lanvlois, and I’ve done many tens of hours on this and other parts already, so we’re playing catch-up.

Buy the selected items together This item: It’s also a smaller value, so my pulses will be shorter, but be able to charge up as fast as the mylar cap can charge. I’m roert comfortable with that electronics that is kind of my thingso I will start there. There’s a problem loading this menu right now.


They provide all of the files and expect people to make it on their own, which is kinda cool. After that, I get about 80VDC, and it should be about 20 amps. Write a customer review. By the way, EDM works well for those metals with low conductivity like steel.

Probably redesign at some point to use some threaded rod and homemade anti-backlash nuts. I needed dimensions of all of the parts to mount and design around this anyway, so a couple hours with their laser cutter files produced this: Very little drawing out of stuff beforehand. Transformer to VAC, full-wave rectifier, big cap, linear regulator Right-to-left: The idea behind this was a very cheap and quick Z-axis for controlling the spark.

Amazon Second Chance Pass it on, trade it in, give it a second life. I’ve pretty much decided that this is a pre-alpha prototype, so I don’t even care about the crappiness anymore. The idea is to pull max 10A from the wall at VAC. If every part of this project sort-of works, then I can prove my concept. English Choose a language for shopping.
