Posted on June 8, 2017 by robertwilkie

The write up was interesting.  but what really got my attention was the information on how these DC motors work from the harddrives. https://www.instructables.com/id/Hard-Disk-Sander/ https://en.wikipedia.org/wiki/Brushless_DC_electric_motor

Make a cheap juice press

Posted on June 7, 2017 by robertwilkie

OK so the next time I see a pipe clamp at a garage sale

Posted on June 7, 2017 by robertwilkie

I may convert it to this.  Now I would not buy all this material to make the build.  Harbor Freight seels a drill press vise for $15 (before coupons).    But if I pick up one at a garage sale…. https://www.instructables.com/id/Simple-DIY-Drill-Press-Vise/

Getting Serial data from Arduion ot RPi to MySQL with CoAP

Posted on June 6, 2017 by robertwilkie

I have heard bits about CoAP in the past, never thought past that.  Looks like CoAP could be a good simple interface for IoT builds.  This one is getting sensor data out to the rest of the system https://www.instructables.com/id/Serial-Data-From-Arduino-to-Raspberry-Pi-to-MySQL-/
