My Interests
I am looking for other Tomoka Heights residents who are interested in any of the following topics.  I can be contacted at Your level of experience is not important - I can help with the learning curve if you wish.  Or you can help me with mine.
  • 3D printing - I have an
    Ultimaker 2
    Ultimaker 2 Extended+.  It has an approx 9"x9"x12" build volume, a heated plate and 20 micron layer resolution.
  • A laser etcher for it - This attaches where the extruder of the 3D printer is located. The printer x-y positioning servos then control the position of the laser over the work. It should be able to etch
    The laser mount
    anodized alumi- num, cut 1/8" plexiglass, wood, foam, etc. The unit I have is the 3.8W version from JTech or search "jtech 3.8w" on Youtube.
  • CAD (and
    A model made using OpenSCAD
    building a higher performance PC to run the modeling programs) - I like OpenSCAD, used to create this adapter to mount the laser to the 3D extruder: Also to make the animation in the lower right corner of this, my MOW Boat Builder's Memorial page (it's an animated gif that takes a while to load but then runs in a loop)
  • Small semi-autonomous drones -
    The "Crazyflie Extended Family"
    I am interested in the open-source Crazyflie 2.0.  They say it was used in the swarm demo at the end of this TED Talk:
  • Macro photography using
    See their site
    a DSLR, 100 mm lens, microscope objective and a rail positioner.  Here is a nice introduction.  This yields 5-10x magnification images.  The rail positioner
    Created using stacking
    (click on image to enlarge)
    From Stackshot's site
    moves the camera a slight amount (e.g. 7-8 microns) closer to the subject between images.  This results in lots of images, each with a different part of the subject in focus.  Then you post-process the images (slices of focus) using “stacking” software which merges the in-focus part of each image into one combined image.  I have the Stackshot rail (also shown above).  It has 1 micron resolution over positioning the rail.  The image to the left was created using image stacking.
  • An Android app
    I wrote for that Stackshot. To the right is a video of an early version of the app.
  • A large format
    Epson 7600
    (23"-24” platten) - I used to have an Epson 7600 and would kind of like to get back into large format prints - e.g. 24"x32" prints using fine art paper and ink.
  • VR & Augmented Reality
    Tango tablet with a Durovis Dive 7 head-mount
    - e.g. Google's Tango (I have one of these tablets with a VR head-mount for it).
  • An MS tablet app

    to collect, organize and annotate heritage artifacts (photos, oral histories, etc). Click on the image to the right to try my web-based prototype. The goal is to port this to the Microsoft tablet (e.g. MS Surface Pro) app and finish it off. Basically, the idea is to make it easy for "Citizen Curators" to annotate heritage artifacts like old photos. Then weave these records together. 
  • Raspberry Pi and Arduino based stuff - e.g. On the Arduino side, I did this a while ago:
  • Website development
  • Traer's Physics library ported to JavaScript for use in Processing.js -
    Lake Placid, 29 June 2016
  • Field Programmable Gate Arrays (FPGA)
    Wow!  This looks like it might be similar to the logic design I did back in the late 70's, as a fresh junior engineer just out of college.  A MUCH different scale, different speed, different tools.  This Field Programmable Gate Arrays (FPGA) development board on Adafruit claims:
    • 22,320 Logic elements (LEs)
    • 594 Embedded memory (Kbits)
    • 66 Embedded 18 x 18 multipliers
    • 4 General-purpose PLLs
    • 153 Maximum FPGA I/O pins
    It would be fun to apply it to Artificial Neural Networks (ANNs), search, etc.

Not technical, but my other interests:
  • Man-O-War Boat Builders’ Memorial - e.g. - the plaques are done and here if anybody might like to see them.
  • Dinghy construction, then dinghy sailing - I'm on my 3rd dinghy construction since retiring.
  • Sailing (Panope in the Med, ANNIE in the Caribbean). My boat is a Crealock 34 located in the Bahamas.
  • Travel (mostly to the Med now, previously Latin America)
