RIP Nanode.

Nanode was great but now migrated to soldercore which is super great :-)

Alas a gap there methinks.

Nanode was great, but most of the other stuff is the wrong side of the price sweet spot IMO.

Electric Imp is currently holding my attention....

Yup, still a massive gap for a cheap (less than £25), low power, IP connected device.

Nick,

 

Have you tried any of the OpenSDA Freescale dev boards (e.g. FRDM-KL25Z ) ? theyre less than a tenner now...

 

Jon.

[Nicholas Humfrey]

Just had a quick look at the Freedom boards and the pricing is indeed good from Farnell but they don't have any built in Ethernet or Wifi?

When you add a Wifi shield, it brings it up to £70.

That’s why I think the SolderCore board is good value @ £60 (http://www.airsensor.co.uk/index.php?page=shop.product_details&flypage=flypage.tpl&product_id=20&category_id=11&vmcchk=1&option=com_virtuemart&Itemid=2) – arduino form factor, robust on-board Ethernet, SD slot, good support and home grown…… and the BASIC coding is very efficient and easy to read J  Works well for me as an internet connected data logger.

Indeed there is, which is why I am going to make a board that has:

100Mbit ethernet
Micro SD card socket
32 bit processor
USB - device or host
512K Flash
128K RAM

Power consumption is almost entirely set by the ethernet port. If no incoming connections are required then it can be powered down
most of the time, in which case battery powered operation should be feasible.

Currently looking at a parts cost of about �12 in smallish quantities.

Looks like a very nice board but what are the benefits over a Raspberry Pi, which is half the price?

Sounds very interesting Nigel!

What will the development environment/OS be?

Much simpler device, remote access via telnet built in and Arduino shield compatible being my favs.

[Nigel Worsley]

> What will the development environment/OS be?

Microchip's MPLAB-X, which runs in Windows, Linux and Mac:
https://www.microchip.com/pagehandler/en-us/family/mplabx/

There are bootloaders for serial, USB device, USB memory stick, SD card and ethernet available. USB in device mode makes the most
sense.

For debugging, or reprogramming after bricking it, one of these will be needed:

I will also be doing a version of the board designed to plug on the back of one of these:
http://www.ebay.co.uk/itm/120963914141

I have a work project that uses a virtually identical display module, it looks really nice!

On a <£25 connected device a few things are coming together.

Indiegogo for a $12 (~£8.00) Leonardo compatible board 
http://www.indiegogo.com/projects/9-arduino-compatible-electronic-board-anyone-can-learn-electronics

TI CC3000 module is making it's way into products. Adafruit mentioned one today in G+. This is a self contained Wifi adaptor that can be used with an Arduino.

The chip is ~$10 in volume, so hopefully the final products will be about £15.00 from Asia.  I'd expect the Adafruit to be more expensive. Maybe even as an Arduino shield.

https://plus.google.com/u/0/112526208786662512291/posts/PhvnrpB4iMX

With the 2 of these together you would have a Wifi connected Arduino.

Looks like technology is marching onwards and upwards.

Albert.

Ethernet shields for Arduino start at around £7 (direct from China, or £10 from UK) - or if you want even lower cost, there are ENC28J60 based modules (the same chip as the Nanode used) for about £2.70

Nice idea Nigle - Id be interested to hear how you get on.

I do think there is another gap for many of my simple data logging
applications: EThernet is a must, but the demand for power and a ethernet
cable in the same locality are a bit restrictive.
Thats why the ELectric Imp concept is really good (and its 002 incarnation
is around $28) makes it smaller to deploy, as well as keeping power demands
down - and as its wireless enabled it checks the box for 'not tied to an
Ethernet cable route'. However, it has a bit of an Achilles heel - having
all ethernet comms/packets being tied to the cloud based server, it means
high availability and exclusive local network use being a risk...

Those Ethernet modules from China are amazing value - bought a couple of them on eBay myself :)

But I think one of the really great things about Nanode is that everything is on one board (MCU, Ethernet and MAC address). That gave some consistency and a platform that sketches can easily be run on - as soon as there are options and differences you loose the momentum that a community gives you.

Really hope that Nigel's board happens - nothing like it at the £12 price point, that I am aware of.

[Jon Bartlett]

Nick - Agreed.

The Microduino stuff looks interesting too - you could deploy a microdiono module for around £20 ish with Ethernet.

Another area of untapped need IMO is Ethernet over power - the concept I've brought up here before - like those devices which are a microprocessor built into a main power plug - but then using ethernet over the mains.  at the moment, I can only do this by buying a cheap passthrough powerline adapter, a 5v phone power device, and strapping my Nanode (or other device) to the whole thing.  This adds up to over £40 which is way too much to be a node data logger....

[Stuart Poulton]

The problem with mains is exactly that it's mains and introduces all
sorts of fun and games.

[Nigel Worsley]

> Really hope that Nigel's board happens

It will eventually, but been a bit busy at work - with what is a prototype of sorts. Just need to leave out all of the unwanted
hardware ( 8 x 14 bit DAC, 8 x 13 bit ADC etc. ) and shrink it from A4 size down to a business card!

> nothing like it at the �12 price point, that I am aware of.

The �12 is a PARTS cost, unless you like soldering 0.5mm pitch chips then build costs have to be added. Not sure what those will be
yet, I will get the final PCB done before asking for quotes.

Those PowerLine plugs are quite power hungry. They're not particularly
reliable either. Not an ideal solution for creating a LAN although they do
have their uses. For 24x7, mains use costs approx 1 pound per watt per year.

Several cheap options are discussed in this thread...

Am I the only one in here who actually also considers the ethical aspect
of labor?
I'll gladly pay the full price for an Arduino made in Italy or a
Raspberry Pi made in the UK, if the consequence is that people are paid
fair wages and can work in safe and healthy situations.
As far as I know, the Nanode was also a European product, respecting
forementioned aspects.

I'm aware that this is "troll-sensitive" matter, so I won't engage any
further in this discussion if this escalates in that direction.

Grtz,
Jurgen.
