Australian version of PowerSwitch Tail

Do you have an idea for a device that you think Freetronics should create? Discuss your ideas here! Sometimes we may even give you a sneak peek at secret projects we have in the pipeline, or ask for feedback on designs before they go into production.

Australian version of PowerSwitch Tail

Post by evan » Mon Jan 30, 2012 12:44 am

(Just emailed this to Jon & Marc before discovering this board (sigh). Thought I'd post it here as well for community feedback.)

Hi Jon & Marc,

Just going back over my notes from LCA and one of them was the idea that I think we discussed on the day for an Australian version of a PowerSwitch Tail like this one:

http://www.sparkfun.com/products/10747

It looks like the manufacturer already has a kit version for switching 240V, where you murder your own extension lead to provide the correct plugs:

I still think there would be a market for a pre-assembled, ready-to-go version.

Possible advanced model feature: PowerSwitch which includes a 12VDC line to power your arduino board.

Best regards,

Evan

There's a relatively large barrier-to-entry for Freetronics or any other company selling a device like this compared to most other devices, because if it's a fully-assembled ready-to-go device with a 240VAC supply then it needs the appropriate approvals or registrations prior to sale.

However it's different for DIY kit devices you assemble yourself (such as many Silicon Chip kit projects you might find at Altronics or Jaycar for example, which use 240VAC) - they don't need to be approved or licensed prior to sale of the kits.

Personally, I think the most constructive, most flexible, most useful thing to do is for people to train themselves in the appropriate knowledge and skills such that they are competent and confident to wire up 240VAC to a relay or solid-state relay themselves with appropriate insulation and enclosure so it is safe. It's not particularly hard.

These days you can get solid-state relay modules which are really extremely simple - two terminals for the AC mains active wire, and two terminals for the control signal, and there is built-in galvanic isolation of the input side, and it will typically accept any old DC signal of anywhere from 3V to 32 V with a very small requirement for current draw, making them extremely easy to connect to an Arduino or whatever.

So will freetronics be making solid-state relay modules single port or 4/8 port modules?
And can ALL there modules come with screw Terminals...

I'll put my +1 vote for this. Lots of potential applications.

I have used these

with a cheap 433Mhz transmitter to turn power on and off. Very easy to get going and works remotely as well, which is a bonus. They are only around $20 on ebay, and the transmitter is a dollar or two.

Nice, thanks.

I found http://www.jaycar.com.au/productView.as ... ID=1001#12 for $18 and then
this http://help.ninjablocks.com/customer/po ... -a-remote- helpful article from Littlebird.

Will have to drop by Jaycar and grab one to play with, with one of my 433MHz transmitters...
