I have just ordered a new lab power supply from ebay. It should be arriving between next tuesday and the tuesday after. So Look forward to some work with op-amps after that.

Due to some offcuts of 12mm square bar from the frames of our Heisler loco becoming avaliable I'm going to make some small test runs of making some atomizers for it.

I can't find any open source CAM software for outputting to a lathe so I'm going to be writing the G-Code by hand in gedit. I'm getting the design from here which I've found to be a very good resource for info in the shay and heisler locomotives. I am making some changes to simplify construction with the avaliable tools (rounding to the nearest metric drill size).

I can post up some CAD files of the proposed design and the G-Code if anyone is interested.

Last night I finally got some time to get some prototyping done. I figured that I should start with a regulator circuit so that I have smooth power for using with op-amps. I will build a more efficient and permanent supply when I need it a bit more but using what was on hand I have a half reasonable output from this hobby train controller that was sitting in the garage.

Just about to start work on the triangle wave generator from this page.

Stay tuned.
Cheers,
Rex


EDIT: Just finished compiling LFS on my server so I should have more time to work on this.

I know it's been a while since I've posted but after just finishing my voyage on STS Young Endeavor and now I have some more drive to get some cool stuff done. I've almost finished compiling LFS on my server so soon I'll have some more free time to work on stuff and I've just ordered an AVR programmer and some op-amps from adafruit.com so when they arrive I'll be atarting to get some projects happening.

Stay posted
