  • Your description needed to be updated. A SPST has no NC contact. This relay will only make a connection when the coil is energized.

  • The cases are nice. But how about this problem:

    In my home weather station (indoor unit), I am using a Mega as the 5" TFT touch panel shield need this. I also am using a Adafruit CC3000 WiFi board (UNO form factor) as well as a Mega type Protoshield that holds my Nordic link to the outdoor portion and a DS1307 and a DHT22. The TFT shield and panel MUST be at the top of the stack. The problem is that the CC3000 board is in the UNO form factor. There is no extension of the added Mega pins. I tried using just stackable header connectors (freestanding) but that was unsatisfactory. I finally modified a Mega to have stackable headers in the UNO area and placed the CC3000 under the Mega board. Does anyone make a mega board with stackable headers (Or for that matter a UNO)?

    My Stack: 1. TFT Touch Panel 2. TFT/Touch Shield (mega) 3. Mega Proto Shield 4. Arduino Mega modified with stackable headers in UNO area 5. Adafruit CC3000 WiFi shield (UNO size)

    BTW: I live in Firestone , CO (however I work in Hillsboro,OR) and have the Ambient weather Solar Shield at my house. It is not really UV resistant and will eventually get brittle and break. I am on my second one in 4 years and I still had to repair it this summer.

    Regards John

  • OK you have the sockets for Vernier. Now when/where can we get the plugs and/or cables? I am in Hillsboro, OR so I may just go down the street to Vernier :-)

  • Just a quick question -

    I am going to be using the PRT-11510 Small Heatsink. Where should I place it? On the top or on the bottom where all the thermal pads and vias are? It seems to me that with this design the bottom would be better.

    Regards JohnK

  • I use a weather tight box that opens on the bottom. I cut an opening on the bottom and covered it with a screen. This fits inside my solar shield (from Ambient Weather) which makes it weather proof and alows the temperature and humidity to be read. This way you get double protection.

  • That sounds like a good idea. Fiber optic will transmit the light with little loss. A multi fiber bundle would get even more light.

    Thanks john

  • Maybe isolation for the temperature sensor? This may keep the heat generated by other components on the board away.

  • What is the i/d of the magnet with the rubber hub removed? The motor drive on my robot uses 3/8" shafts. What is the o/d? I also suspect the magnet will pick up all sorts of cr_p from the ground if mounted to close to the ground. Fortunately my motor mounts are 6+“ above the base.

  • I suspect 1/8 of a revolution based on the 8 poles of the magnet. Edit – I forgot there were 2 sensors. jwatte is correct!

  • Let’s see now - The light sensor is buried on the board. So if we are in an enclosure (ventilated) there is no way to determine the light outside the enclosure. Is there any way to remote the Light sensor? Other than that it looks like a great board. I will be ordering one soon.

No public wish lists :(
