Having a go at Arduino, VSCP and CAN

Even though I'm still in my planning and initial development phases, I thought I'd share what I'm thinking so if you have any good ideas, I could use them. So, I've looked at VSCP for some time now and it looks very good at the automation stuff. Using CAN seems to be able to provide a stand alone sy...

Re: Ep 5: Installing conduit under an existing footpath

I must say I was very surprised how fast you got under the footpath. What is your soil like there? I've not been game to try that method due to the very hard clay I have here.

Re: Ndrive driver module, PWM, FET open circuit

Hi, I'm not sure what is meant by high loads, but the reference sheet http://cdn.shopify.com/s/files/1/0045/8932/files/NDRIVE_NDriveModule.pdf?100736 says that you may need a heat sink. How hot is the FET getting? I'm no FET expert, but I'd be not using a common ground on those two circuits. The FET...

Why 7V output from PR28V, why not 5V direct?

I'd like to understand why the PR28V doesn't just regulate the voltage down to 5V and skip the onboard regulator? It would seem to reduce the power requirement of the board as my understanding is that he linear regulator does eat a reasonable amount of power.

Re: Ep 3: Power-over-Ethernet for Arduino Home Automation

I wanted to ask about the choice of commercial PoE vs using the 28V switchmode. The commercial PoE is more expensive in client on the Arduino and switch hardware. It is also larger, requiring custom modifications as in this video to allow a shield on top of the EtherTen. The 28V switchmode does not ...

Re: Sourcing buttons used in Superhouse's light switches?

Thanks thats a great help. It did remind me of your walktime blog though. The one where you covered the creation of the light switches. I would be interested in getting hold of the light switch boards or some form of a revision of them. They would be great as plain board and I could easily chose som...

Re: Lighting control 12v switching vs 240v switching

Most excellent! In my houses design I could easily have 2-3 transformers with only 2-4 metres of 12V DC cable to connect up all the lights. The current design is lookings something like; 1 Arduino, 1 8xRelay board, 1x 100W LED driver and up to 8 LED lights connected. That allows individual LED switc...

Re: Sourcing buttons used in Superhouse's light switches?

Yes, $24 worth of switch is a lot, make the idea of having a single on/off switch even more attractive. Only need $4 per light, not $8.

Do you pick them up from Jaycar or some other store?

Mounting PoE module Under EtherTen

Given the recent complaints in the Network stops working thread about heat and the device not working, I wondering about any potential issues with fitting the Power Regulator 28V under the EtherTen rather than on top where it interferes with any shield space you want to use at the front of the board...

Sourcing buttons used in Superhouse's light switches?

Hi,

Where do you source the buttons you use in the light switches, I googled around and found them for $4 each. It feels expensive, but it might not be.

Thanks
