It’s only 60v my final circuit is 80vbut the principles don’t change with the lower voltage. Robbert swapped the order of the caps because I believe the mylar one will hold up better to repeated fast discharges. My hackspace where I’m building this got evicted a robwrt months ago.

Other than wanting to spend very little money on this project, the scope of it is huge enough that I’ve been trying to use as many prebuilt components as possible. Amazon Renewed Refurbished products with a warranty. Yes, delete it Cancel. These values aren’t anything close to final, I’m just playing around.

These are rated for 2A continuous at high temperatures, so I may have to put to a couple in parallel. I don’t even know if this emd work!

It’s a space ship! Most of the EDM schematics out there are just rectifiers and timer-based pulse circuits. So I did some more work, rebuilding that output power board: Ships from and sold by Amazon. One thing I couldn’t find on their site anywhere was the work area. His version seems a unnecessarily complicated, though.

You should Sign Up. Heading down there a couple days later, well into the packing effort, to grab my project evm, I couldn’t find it where I left it.

I need some sort of analog readback at each of the stages.

The idea behind this was a very cheap and quick Z-axis for controlling the spark. The hardcore kind of machinists that don’t really internet well. There seem to be about three resources on the internet for details on the buile workings of these machines: Similar Projects The Hackaday Prize.

Not Your Father’s EDM

How well this works will depend heavily on how well I can filter out the noise edj arcing. If every part of this project sort-of works, then I can prove my concept.

I’m following this one closely! I think I can use this to directly erode paths eedm traces on a sheet of copper-clad. The new place is a fair bit smaller than the old place, so we’re in a purge phase. My buuld is that plunge EDM often uses machined graphite electrodes although my only real exposure to the topic was in the MIM tool manufacturing world.

If I come across a transistor that is slightly faster, lower Rds this is 5 Ohm – too high!

That will be fun, I am looking forward to it. I plan to eventually draw around 10A in pulses.

Amazon Music Stream millions of songs. Explore the Home Gift Guide. The langloiis can be broken up into two sections: Well, I need to, to know what’s going on during a burn. This is the start of the power stage. The mechanical guys have got the first two figured and polished to a degree that I’m not capable of. Amazon Rapids Robfrt stories for kids on the go. I haven’t lost interest or anything quite the opposite.


As you can tell, I’m just plowing on and building things for this project. If you need a square hole, or other unique shape in a part make a square electrode and burn it into the part. View shipping rates and policies Average Customer Review: 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 as high duty cycle as my mechanical system will allow.

Discover Prime Book Box for Kids. Here’s a P-channel solution that I should have started with, given, like, 5 minutes of critical thought:.

If you can get fine control of the up-down movement, then you can sustain this arc for a longer period of time, getting a better burn. East Dane Designer Men’s Fashion. That is made more difficult by the hackspace being in a state of flux at the moment after having our lease unexpectedly terminate recently. After building it, there are a couple problems. 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: Then I need to limit current to 20A when cap 2 is depleted and transistor 1 first opens up, but doesn’t limit current as much when cap 2 is half-charged, for example.

It’s called the Piccolo: For measuring voltage and current, it’s a little bit challenging when I need to keep the supplies isolated.
