===Friday July 4===
 
Micro Power Cube workshop with Tom Griffing. We need to build three or four power cubes to operate the soil mixer, soil pulverizers, lifetracts, and other machines.

===Wednesday July 2===
 
First tractor lesson on the lifetrac 4 with Aidan. We used needed to replace the battery, as well as the solenoid. Greg made an instructional video on how to repair a solenoin. We began repairing soil mixer, by mounting a hydraulic motor. We made a coupler with a 1 3/8 diameter six spline tube connected to a section of 2 inch pipe. We (Greg, Michael, Aidan, and Moriah) turned the spline in the lathe, which is a magnificent dinosaur of a machine. We also torched a hole in the motor plate using an oxy-acetylene torch.

===Thursday June 26===
Reviewed notes from the brick press build and continued to update the drawer, drawer guides, and secondary cylinder modules. Painted the walls and ceiling of the solar cabins white. The septic tank's leech field is slowly flooding and the plumbing is all disconnected. Woo no water.
 
A note on hydraulics: compression fittings with swivels or ones that have rubber o-rings(sae) dont need thread tape. The reason you dont cover the first two threads on nptm and nptf fittings is because because some of it might end up in the hydraulics.

Reviewed notes from the brick press build and continued to update the drawer, drawer guides, and secondary cylinder modules. Helped mount plywood walls and OSB flooring in the solar cabins. Tim Gravlin from USDA came again and we planted two more rows of tomatoes, edamame, jalapenos, and green peppers.

===Tuesday June 24, 2014===
Reviewed notes from the brick press build. Worked with Anthony trying to document the process of opening and modifying files for the CNC torch table on LD3 of the liberator. We were able to fix all the issues with the part programs. Files should first be opened in libreCAD to create polylines and equidistant polylines .0368 inches off, internally for internal cuts and externally for exterior cuts (This is one half of the 1.87 mm kerf of the torch). You should also delete all the layers in libreCAD except for the visible layer and the layer 0. This reduces file sizes from ~1 MB to ~ 50 kB. Next open the dxf file into inkscape and scale it by 25.4 to convert from inches to millimeters. Set the default units and custom units both to mm and set the custom size to 500 by 500 mm, or whatever the size of the metal you are cutting is. Save it as a .svg file. You can change the order of the paths by using the XML editor in inkscape and dragging the individual paths into the order that you want. Internal holes should be cut first and the perimeter should be cut last. While still in inkscape, use the node tool to select a node where you want to add the lead in and lead out. Break the path at the selected node and then select the node. With the drawing tool you should be able to click once on the node, and then click again where you want the path to start. Do this twice for each node to account for both the lead in and the lead out. For internal cuts this should be the center of the hole, and for external cuts it should be 1-1.5 cm away from the edge of the part. Save the svg file again and upload it to lasersaurApp. We are currently using an ethernet cable to connect to lasersaur.local. This worked for me in mozilla firefox but not in chrome for some reason. Check the tool path preview in lasersaur to ensure that the cuts are starting at the lead in's, and cutting the perimeter last. Export the gcode from lasersaurApp and add the pierce routines in notepad++ after each G0 command. The current pierce code also has G0 commands in it, which makes this slightly confusing. Use find and replace to replace \n with \\n and \r with nothing. Finally, in lasersaurApp, right-click and inspect element to pull up the html. paste "send_gcode([paste gcode here]......) (I'm not sure what the exact command is. Check anthony's documentation.) with the gcode file pasted within the square brackets. Set the nozzle height 7 mm above the surface of the steel (for cutting 1/2 inch thick steel plates). This should produce a successful cut with the correct path order.

*Worked with Tim from USDA to planted agriculture in the field:
**Row 1: Sweet Potatoes
**Row 2: Sweet Potatoes
**Row 3: Sweet Potatoes and Sweet Corn
**Row 4:
**Row 5: First half (West half) edamame, second half jalapenos on the south side of the drip line, bush green beans on the north side of the drip.
**Row 6: Tomatoes: roma and cherry.
 
 
*Seed are stored in the old workshop include 3 lb of sweet corn, zucchini, yellow squash, and edamame.
 
*To Do: Prepare thin metal wires to pin the drip lines in the center of the rows.
 
*Tim's suggestions: Add livestock (chickens/rabbits) Other crops, more drip lines.
