we choose to go with a black pipe frame for the z-axis. we cut down the existing head carriage to fit the new design then mounted everything in place. we almost have a fully functional 3D printer. just need lead screw and motor for z-axis, then testing.
we found this great old beat up all sport trike at a farm auction. took it as seen for $5 dollars. also picked up a couple of 3.5hp briggs&stratton motors that we pieced together. with an hour of design prep to inform our purchases we went to the hardware store and grabbed the parts we needed to build a drive train. after some cutting, tweaking, and testing, we had this vehicle running at about 25mph by the end of the day. it was a fun low cost engine hack.
after spending a pretty good portion of the night getting the structural aspect of our z-azis on the 3D printer in completed and built, we spend the rest the night and the next morning putting together this new lab.
this unit has performed at around 2 meter accuracy on a good day. the gps reciever is a LS20031 and the chip is a LOCOSYS MC-1513. we will be interfacing it with an android via usb or bluetooth eventually. we've used tinygps as our software along with arduino.
we recorded the below footage using a video camera adapted to a microscope and output to a laptop. we didn't hack this per se, one of our memebers owns the tool, but we did have to set up the tools, gather the pond water, and chase this guy around. might seem boring now, but we were very excited during.
there was some debate about this life form. some thought it was a recently publicized nuisance. still unresolved. see pictures below.
this is the result of a GPS survey conducted by fredhack. we gathered the GPS survey points and lines with a trimble device then imported to google earth. its nothing special, but shows the possibilities. we had a great time making this one driving around on a supped up golf cart.
this electric pick, or e-pick, was invented by Russel H. it is used to chisel out fossils embedded in rock. the design is simple and effective. it also doubles as an amateur tat-gun. newer versions to be posted soon.
