  1. The HubPages site is down again. How is this project coming along? I came cross this PLC Ladder Logic programming for the Arduino and thought you might be interested. http://soapboxautomation.com/snap/ladder-logic-on-an-arduino-uno-a-sneak-peek/

  3. New panStamp NRG is finally available for purchase http://www.panstamp.com/announcements/panstampnrginstock
  4. Microcenter has Beaglebone Black rev C now through 23rd? for $40 ($15 off) http://www.microcenter.com/product/434844/Element_14_Beaglebone_Black_-_Revision_C
  5. I backed this Kickstarter project https://www.kickstarter.com/projects/1630453569/angelblocks-smart-wireless-building-blocks-for-sma but it didn't quite make its goal. Same developer as the Whisker.
  6. @@Lgbeno If you are still interested in LoRa you may want to take a look at this https://www.kickstarter.com/projects/1630453569/1593959267?token=d64e265c

  8. Well, not an MSP but the Wink home automation hub does have two TI CC1101 for 433Mhz communications with Lutron and Kidde devices. The board is nicely labeled with the 5 different wireless radios (WiFi/BT, Z-wave, Zigbee, Lutron, Kidde) http://community.smartthings.com/t/wink-hub-teardown/3288
  9. The new panStamp NRG is still in beta. If you e-mail them or post in the panStamp forum they may have some they can sell you.
  10. @@pine, I agree the price is a little too high to just tinker. What hardware are you using for openwrt? I would like to find one with a lot of IO expansion capabilities. I was hoping for this one https://www.indiegogo.com/projects/arbor-linux-shield-an-openwrt-wifi-development-board-for-arduino-other-mcus/x/4207492 but it didn't make funding.
  11. Relatively low power 500 MHz X86 CPU, 100 MHz Quark acting as MCU, Wifi, Bluetooth running Linux. What do you think?
  12. @@abecedarian ESI project to monitor his nephew's water and power usage got me thinking about this again. I came across this 6 channel energy measurement IC. Seems like it would work well for monitoring multiple circuits from one location such as your home circuit breaker panel. It would allow offloading all the complex voltage and current phase calculation to an external IC and just collect the values including power factor etc. over an SPI or I2C link. http://www.analog.com/static/imported-files/overviews/ADE7816_Multichannel_Energy_Measurement_IC.pdf
  13. My city water rates are sky high so I was looking for a way to monitor my water usage and hopefully reduce it. I came across his paper "Single-Point Sensing of Whole-Home Water Activity" https://homes.cs.washington.edu/~jfogarty/publications/ubicomp2009.pdf . They call the system HydroSense. Instead of using a water flow sensor at every faucet, tub, shower and appliance that uses water, a single pressure sensor is used to detect the water usage at every location. This is accomplished by learning and recognizing the unique pressure pattern when water is turned on or off at each water usage location. In this way you know not only how much water is used but also which location is using the water without the high cost and complexity of installing sensors at every location. One of the objectives of the HydroSense systems was to make it portable for a quick and easy install. Therefore the single sensor/MCU was battery operated and could be installed on any water outlet including an outside faucet. The following are the major components of the HydroSense system as described in the white paper.
  14. Got my target board today so need to get in gear and start my project log this weekend.
  15. @@nathancrum, If you have not already, you could look at the panStamp for a possible pin layout. http://www.panstamp.com/products Their current battery board is for a AA since their previous design used AVR but their new (NRG) design uses the CC430
