These are for my Boy Scout troop. They are being made on my homemade CNC machine. The plans for the CNC I used are here. There are newer plans now - these will be the next machine I build. This is where I got my electronics.

Click through the pictures, and I will tell the story.

Saturday March 27th LVL1 is putting on an Electronic Mischief Soldering workshop. We'll be building TV-B-Gones and a surprise kit for computer pranks. Register online at eventbrite at the link below.

Eagle layout for triple sensor board

This sensor board is for summer 2010 research students to carry out studies of sediment transport in streams. It's for the SALAMANDER project: Serial Amphibious Linear Arrays of Micro And Nano Devices for Environmental Research.

It is mostly connectors with a few chips in between to sense ambient light levels, flow velocity and temperature. For the first time, I tried the SparkFun staggered Eagle footprints that are supposed to hold the connectors tightly during assembly and soldering. A solder stencil for the red pads is also on the way.
