I forsee folks getting free parking in the future

The author figured out how to sniff some of the garage gates and get them to trip using an 433 MHz OOK module and an arduino.  I see a future here where folks use this to bypass parking garage gates. … Continue reading

This plotter is the perfect build for kids

This plotter could not be easier to build.  4 rulers, 2 steppers, and a servo are all you need…oh and ways to bolt the rulers together.  Oh and an arduino and stepper controllers too. https://www.instructables.com/id/CNC-Dual-Arm-Plotter/

HAHAHAHA this is a pretty clever build for cutting bars the same size

The author uses an arduino and a home made encoder to measure the cuts. http://hackaday.com/2017/06/04/arduino-and-encoder-form-precision-jig-for-cutting-and-drilling/

Getting Serial data from Arduion ot RPi to MySQL with CoAP

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-/

OK adding this to the list of things to build

A sand/zen garden.  This looks easier to make than a CNC since its only two axis and a big magnet.  Making the “sandbox” maybe more of a challenge.  And as the article says, its been done other times too (I … Continue reading

This is cool build, ESP with e-ink

Low power, checks in for new images every so often.  Nice build overall.  Oh and cheap.  Basically the author is building a display that will get updates once every hour and run on solar power.  I could see something like … Continue reading

Another simple CDROM CNC plotter

Another nice build with an arduino.  The author uses an arduino nano and some L293D chips which keeps the cost down compared to some CNC CDROM builds.  I also like the use of a pen spring to help keep the … Continue reading

Make a remote control snowblower

This is a multi year build.  The author took parts from 2 snowblowers, and electric wheelchair, tossed in an arduino and built this.  I think he says the total cost was around 1200…most in the snowblower/wheelchair bit.  Me…I am tempted….but … Continue reading

Microsoft Joining the rest with Linux and IoT

Microsoft has apparently released code for Linux that will allow for IoT devices to contact Azure based systems. https://www.theregister.co.uk/2017/05/11/microsoft_azure_iot_cloud_offering/
