  • DIY grassmaster

    Hi all, I borrowed a Noch grassmaster but I think it's a bit hefty price wise.

    I then saw the article by Luke Towan on how to build your own.

    I didn't like to have to scurry around to find the hardware though ...

    The electronics were all readily available, and I ordered all of it online.

    A friend and I decided to build one each.

    The housing then?

    I would like the ability to alter it and change the cups and nozzles to suit various types of applications.

    I designed it in CAD and made it as small as possible but still be easily assembled.





    It has features I like, as the ability to run on both 12 volt thru a cable or with a 9 volt battery. All controlled with a three way switch.

    The prototype is currently being 3D printed. It will be used to see if any alterations has to be done.

    The print turned out really good!

    Now it's assembly and soldering time.

      That is pretty cool and fancy! Well done. Is it available for purchase? Download? Ordering? I've no idea how 3D printing works....

      cheers,

      Dave

        If interested, I might be able to print one extra at cost plus shipping. It isn't really viable to upload the design to Shapeways as it would be too expensive...

        My homemade will cost around $30-40.

          Michael,

          Very nice design! Where did you get the high voltage module?

            Thanks, the ion generator is from Oatley electronics in Australia.

              First test of the home-built grassmaster with a 9 volt battery for power and Woodland scenics short grass.



              Tomorrow I will test with the 12 volt trafo and longer grass.

              I was surprised how strong the static field is. The hair on my hand stands straight up when I get close ...

              The grass gets really dense and stands up really nice.

              This project gives a good result.

              The cost was really affordable. When summarizing every component and the material for the 3D print, it cost me roughly $50!

              Under half of what equal products on the market costs with the same specs.

                  Hello Dave, people are out there looking for you.

                  Very nice indeed! I like your version. Beats the fly swatter How-to that I did. That ion generator makes all the difference in performance.

                    Michael, at 9v it's working great. At 12v it might work like a Tesla coil. This could be you.
