Batches underway !

After several month working of Bee improvements, new PCBs for Jaluino Bee v2.1 have been ordered from SeeedStudio. Several other PCBs have been ordered as well: some more Mini-Crumboard, and a new shield, Mini-ProtoGrove. I’ll post more about all of this when I get PCBs and build new Bees. In the mean time, you can have more details in forums and pre-order PCBs:

Adapting microSD socket hinged type for Bee v2.0

When I designed first versions of Bee, I mostly used Sparkfun Eagle library, as an habit, and browsed eBay on the other side in order to choose components: one that’s available in Eagle and cheap enough on eBay. By this time, I selected a microSD socket Push-Push type:

These were easily found on eBay, at a decent price, I ordered 5pcs (~$5). Since then, these aren’t available anymore, alternatives sources are much more expensive, something like $3 to $4 per socket. This somewhat kills my low cost approach… Another drawback is pins are under the case, which make this part hard to solder, probably the most difficult one.

Building a powermeter with Jaluino Bee

You may have heard about “Internet Of Things”, platforms mixing hardware and software projects to publish and share data accross the web. The idea is to have some hardware collecting data, and publishing it on a website. One successful example, open source & free, is ThingSpeak, used here in this post.

So, Jaluino Bee is cheap (~$10 if you build your kit yourself) and that was one main goal while designing it. A reason is the cheaper it is, the more you can put Bees as things in the internet. This is the idea here: collecting electrical consumption from a power device and publish it on ThingSpeak.

Jaluino Bee v2.0

(but where is v1.0 ?…)

I’ve been working for several months by now on a new Jaluino board, Jaluino Bee. I’ve designed a first PCB (v1.0), tested it with more or less success and now have ordered (and received) a second batch of PCBs (v2.0). From all i could test it seems to work “out of the box”, so now is the time to expose this…

Upper three board: Bee v1.0 with more or less “green wire” fixes. From left to right: Jaluino Bee[z] powered by PIC18F25K22, Jaluino Bee powered by PIC18F27J53 (lots of fixes…) and Jaluino Bee[p] powered by PIC18F2550 (because I had some in my box…). On the bottom, Jaluino Bee v2.0 powered by PIC18F27J53 (no more “green wire” fixes), sweet…
