CNC Part 14

images: 

Here is cutting a little drawer that turned out great.

I inadvertently learned that this FLA-100 clone will cut steel when my 1/4" carbide tool path intersected one of the 5/16" washers I was using to hold down the work. At 60ipm there was an ugly chatter but no steps were skipped and the job completed perfectly. I'm pretty excited about trying some aluminum now.

Solar Panel

images: 

A recent hobby has been to build and install a solar panel on our roof. It's comprised of 36 common Evergreen Solar 3"x6" 1.8W cells in a simple wooden frame with a sheet of acrylic to protect them. My Dad helped run conduit and wires last weekend and the open source hardware/software available these days makes it unbelievably easy to setup a voltage logging apparatus. A 10k then a 2.2k resistor straddle the wires coming into our basement from the panel. The junction of those is connected to an analog input on an Arduino Mini.

New Dual VCA

Just finished a new dual VCA as described here. I had the board sitting around half done all summer. The worst haphazard panel layout I have done yet.
