Projects – Hobbybotics SHT1x Humidity/Temperature Breakout V1.0

I designed a breakout board for the Sensirion SHT1x Humidity and Temperature Sensors.  The SHT1x family of sensors can measure relative humidity, temperature Celsius and temperature Fahrenheit.  My plans are to use the design for various heating and control projects such as a wireless thermostat, greenhouse controller and some environmental projects.  The project link details a SHT15 but, any of the sensors that share a common footprint can be used with the breakout board.  I also developed (modified) an Arduino library for use with the Sensirion sensors.  Check out the project here.

Tools – FireBall V90 CNC

Today I managed to gather enough nerve to purchase a FireBall V90 CNC machine with all the bells and whistles from Probotix for under $2000.  The V90 has the following features:



  • Approximately 12″ x 18″
  • Thomson precision linear shafts
  • Oilite bearings
  • Precision Acme 2-start lead screws
  • Anti-backlash drive nuts
  • CNC USB controller and software
  • Aluminum T-slot extrusion spoil board
  • Bosh Colt PR20EVSK Router and holder
  • MeshCam software
  • 3-Axis ProboStep Motor/Driver Kit
  • 40 VDC Linear RTR power supply
  • Larger enclosure for power supply and motor controllers
  • 220 in/min rapids

The machine is supported by the  FireBall CNC Yahoo Group.

Projects – Hobbybotics MAX6675 Thermocouple Breakout V1.0

I designed a breakout board for the MAX6675 Cold-Junction Compensated Type-K Thermocouple interface.  My plans are to use the design for various heating control projects such as a Sous-vide cooker, wireless thermostat, smoker controller, beer brew controller, reflow oven and some environmental projects.  Check it out here.
