How to print on fabric

Posted on February 14, 2018 by robertwilkie

Actually on a nylon net.  Pretty cool idea, you start the print, pause it, put the net down, then print some more. https://makezine.com/2018/02/12/3d-print-fabric/

Neat necklace build

Posted on February 14, 2018 by robertwilkie

I like this build, its a bit larger than I would have done, but its neat build overall.  Not sure what the stone is he uses. Beating Life-Force Amulet

Neat remote LED sign build

Posted on February 12, 2018 by robertwilkie

The author is using a variant of an ESP board to send text wirelessly to the sign.  Nice build overall.  I remember when signs like this where pretty common in the 90s.  Its also a really cheap build to do … Continue reading →

A simple water sentry

Posted on February 8, 2018 by robertwilkie

This is funny.  The author needed to get rid of some pesty deer eating his roses.  So he built a water blaster sentry (attached to hose for water ammo) to track and guard them.  I am surprised he didn’t used … Continue reading →

A hockey puck drone

Posted on February 8, 2018 by robertwilkie

This is a pretty neat looking drone.  Seems to move pretty slow and fluid.  Its made by Cleo Robotics.  Its still a prototype right now, and no word on cost. https://spectrum.ieee.org/automaton/robotics/drones/cleo-robotics-demonstrates-uniquely-clever-ducted-fan-drone?utm_source=feedburner-robotics&utm_medium=feed&utm_campaign=Feed%3A+IeeeSpectrumRobotics+%28IEEE+Spectrum%3A+Robotics%29

Now I only need a good sized laser cutter

Posted on February 7, 2018 by robertwilkie

This is a nice build, and the plans are free.  But…you need a laser cutter to cut all the parts out.  I wonder if the author will “kit” this project for those of us without laser cutters. https://www.instructables.com/id/Laser-Cut-Machinist-Toolbox/

Interesting dot matrix printer

Posted on February 5, 2018 by robertwilkie

Interesting build for a dot matrix printer.  Looks pretty easy to modify for muli colors too.  I like how its adjustable for “paper size”. https://www.instructables.com/id/Doter-Huge-Arduino-Based-Dot-Matrix-Printer/

This is one crazy plotter

Posted on February 2, 2018 by robertwilkie

OK its using an old scanner bed, CDROM drive for the Y axis, and a harddrive seeker to whack a pencil on the paper.  Well worth watching the video. Junk Build Printer Uses Pencil To Print

How to convert a BluePill into an Teensy

Posted on January 29, 2018 by robertwilkie

$2 for the board….no wonder the author went thru the trouble to convert it to a Teensy based system.  Teensy’s run around $20.  Typically when I hit that point I start thinking about using RPi’s. http://coytbarringer.com/programming-stm32f103-blue-pill-using-usb-bootloader-platformio/

OK I think I would have spent the 20 minutes cutting the wire
