Nice looking CROM CNC machine build

I like this build since it allows for you to move the CNC to different surfaces.  It looks really professional and the frame is really well done (hand cut from acrylic sheet).  Unfortunately no plans or dimensions for the sheet … Continue reading

Neat remote LED sign build

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

Interesting dot matrix printer

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

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

$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/

Cool light

This is a nice light build.  I like the jig the author made for carving out the center of a 4×4 post too. https://www.instructables.com/id/FADing-Fall-Asleep-Device/

Arduino controlled finget Jointer

Now this is a build I was looking more for in a jointer for your table saw.  The arduino with a stepper is used to move the wood into each position to make the next joint.  I like the hold … Continue reading
