Clean looking sensor node
-
Found a few more things. If something a tad bigger than the OP's puck were needed, then there's this at almost the same price:

Not all of them though. Here's a couple that seem like they wouldn't look too bad, but for most things solar the prices are much higher than for a non-solar version (as you'd expect);
http://www.ebay.com/itm/12000mAh-Portable-Waterproof-Solar-Charger-Dual-USB-External-Battery-Power-Bank-/112160398867?var=&hash=item1a1d47de13:m:mSNAshLEYCjRnRKBS7jvE7Ahttp://www.ebay.com/itm/272407702880?var=571371942032
I like the look of the last one better, but of course it costs more than the other solar cell charger, so that's the trade-off.
From what I've read, most of these portable solar chargers would take a very long time to convert enough solar into enough stored energy to charge a phone, and so people end up mostly charging them from a usb charger, defeating the main purpose purpose of it. However, for powering a wireless sensor node, I suspect they capture enough solar from ambient light that they could be retrofitted for that purpose., at least for nodes that can sleep and don't always need to be running.

Ah yes the "Q8" square charger looks great, I'm waiting for my new credit card to arrive to be able to order one :D It's a bit bigger but it looks slick and it would allow to combine a few sensors inside. It could also contain a charging circuit and lipo to have rechargeable sensor.
For the others, well I believe I would get high WRF (with R like rejection) instead of WAF :D

@Nca78
I'm not really offended by the QB logo, but I'm guessing you would prefer one without the QB logo:or
Mainly because of the lengthy shipping delay, I think I'll get one of each and then decide which I prefer. Things don't always look the same on a website as they do in real life.

Looking at the containers in our pantry here, I notice a lot of them have lids that, though they lack "bottoms", in many respects look a lot like the generic "puck" shape of the OP. For something that sits on a table top, you'd never know it doesn't have a bottom. These would be entirely free, because as my family here uses up a container, we invariably just throw it out. :-)

I just today received an all white version of this (purchased it from ebay), but I wouldn't recommend it (well, at least not this color). The case itself is all white, which is what I wanted, but the silicon ring embedded in it is more of a cream color, and so it ruins the look by making it look old and/or dirty. It doesn't look like the photo on the web page. Also, as perhaps the OP pointed out, there are no vent holes, though they could be drilled.

Here's another one, but this one I like. For a sense of scale, I photographed it with my large TH sensor sitting on top:
-
You're receiving thing pretty quickly (as you received the PCB in less than 2 weeks, too), you're lucky !
I have no problem with the white ring on mine, it's not the same color than the plastic but it's not looking bad to me. Maybe different model, maybe a question of taste ;)

What do you think of the black one above? Thumbs up or thumbs down? I was surprised at the way it photographed. On the sides it's actually the same glossy black color as it is on top, but its so glossy that when I photographed it (with a flash) you're actually seeing a reflection of the white tabletop that it's sitting on. Similarly, you can also see a reflection of the white antenna on the glossy black portion on the top (though not in the matted black top area).The things I received yesterday were shipped domestically. It still takes a long time to get things if they're shipped from China.

In the spirit of KISS, I think in most instances the following might work well for me:
My smallest wireless node can fit inside the case along with 2x AAA batteries positioned to produce 3V, and the case already has an exposed switch to turn it on/off. Total case size is relatively small, around: 6.2 x 4.8 x 1.5cm / 2.4" x 1.9" x 0.6"(LWH)
-
I'll definitely order this and the AA version too, to check.
In the worse case it can be used for hidden node. It should fit a dedicated PCB even with pro mini as long as the radio is SMD to be flat enough. -
Newbie here.
I have used battery casing for sensebender & DC DC step up converter (2.5v to 5v).
Have to do a bit of filing & swapping of battery contacts and drill hole for sensebender.
Attach photos.
Yup, your photo captures the notion of what I'm planning to do:
My original inspiration for it came from this:
http://johan.kanflo.com/the-aaduino/
which I might have done, except that I prefer the RFM69HW, which I don't think would fit in just one battery slot very easily. -

Here I just received the black "pucK' sensor case that was shown in the OP. Pretty fast considering it was free delivery using China Post. So far I like it the best because it has the air vents already a part of it. :smiley: -
That's why I selected it, best suited for temp sensor.
Just received the first version of the PCB but it will need some improvements.
But looks like it will work, not too bad for my first PCB ever :)

I really like the pcb´s you are using @NeverDie, is it possible to buy them anywhere?

I'm just doing this for fun. If you want to buy something pre-made, I'd suggest buying a Moteino.

Ok, but is the PCB availible at OSHpark or is the files availble for sharing?@Cliff-Karlsson
Maybe later. I'm still improving the design.
