Re: 3D Electric Potential

Thanks Justin! I've downloaded it and will take a look! I'm hoping to apply some of the techniques I learned in my intermediate ODE's course this fall about analyzing singularities in vector fields to get a better idea of particle behaviour. I've started with the simplest grid shape here, but I have...

Re: Catalytic converter shield augmentation?

This past winter up in Edmonton, my catalytic converter on my Honda CR-V was nearly stolen twice, both times a thief with a sawzall was interrupted and only managed to mangle my exhaust pipe. Was much cheaper than $3000 to get the exhaust welded and repaired but still deeply annoying.

3D Electric Potential

Rather than continuing my previous post on a python simulation I felt it best to break out a new thread with some of the additional work I've been doing on the computer over the holidays. I've chosen to start the next aspect of my simulation project by picking up a new programming language again. It...

Re: Farnsworth Questions

Thanks Frank! Always love to read the original stuff. After reading Joe and Richard's comments I remembered I'd downloaded an archive of documents that had been posted on Fusor.net awhile back (I can't remember who posted them, my apologies!), but with school and other work I'd simply forgotten abou...

The routing is now complete and all that's left to do is send it off to the board house!

Re: LCD Vacuum Sensor

Routing on the board is now completed, I still have to pour the ground plane and place some mounts if I want to put it in a case but progress is progress. I'm never 100% sure about how to route things well, but this is a simple circuit so I don't anticipate too many problems.

Re: LCD Vacuum Sensor

As we're in Christmas holidays I've gotten back to working on the vacuum sensor. I'm currently in the process of laying out the PCB in KiCad. There's lots of finicky details to work through to make sure positioning is correct but the broad outlay of the board is visible. The amplification circuit an...

Re: Farnsworth Questions

Have any of Farnsworth's notes survived to the present day? In reading Richard and Frank's recent posts I was struck by how so much of the discussion of his ideas has to rely on secondary sources. I would love to see any scrap of paper where he wrote down his ideas about what he was trying to accomp...

Re: Python Simulation

Very cool Nathan, as an aside my dad did his undergrad at Kansas State! Yes with 3d I think visualisation is quite difficult, I'm not 100% sure on the tack I'll take yet. From my research the easiest way to do it seems to be to take "slices" of the field at different heights, so you calculate the fi...

Re: Python Simulation

I figured it was time for an update on this little project. Over the summer I monkeyed around a bit more with the code, it correctly simulates a 2d electrical field from a grid, and I can place a particle in the field and watch it move (if you'd like the completed code I can post it here). However, ...
