Computing stuff tied to the physical world

What a year it’s been…

In Musings on Jul 13, 2010 at 00:01

One year ago, the first serious PCB designs were “taped out” (heh, if that isn’t an anachronism by now!) – this is when the first batch of JeeNode v3 boards was produced, with all the ports and pins that have by now become a standard around here.

One year later, there are 4 JeeNode variants and over 20 “plugs” / add-ons – all part of a happy JeeFamily :)

What’s next? Well, I don’t have a crystal ball. But I do know what’s coming next because of some recent projects behind the scenes … and I can tell you that there will be several new plugs starting mid-August.

Another announcement I’d like to make now, is that after the summer more of the production will be out-sourced (here in the Netherlands), to free my time for work on new hardware and software development.

As you probably know, Jee Labs is just me, moi, and myself – with a few great people helping out behind the scenes. The major difference with traditional companies is that I’m neither driven by a boss, nor (primarily) by revenue, but by interest. Which means that you can have a considerably larger influence on where Jee Labs is going than you might think… all you need to do is speak up, preferably in the discussion forum, and point out neat / useful / practical stuff. I won’t guarantee that I’ll follow everyone’s lead, but I’m as keen as anyone to go where the neat stuff is regarding physical computing.

Speaking of neat stuff…

Franz Achatz sent in a great email today, describing what he’s been doing, complete with pictures and screen dumps. Here’s the latest addition to his RFM12B-based WSN – a fridge sensor (posted with permission):

Dsc05480

All in a neat little box, with the GSM-type antenna sticking out:

Dsc05478

The sensor is a 1-wire Dallas sensor, to allow tracking the current temperature inside the fridge.

And here’s the software side of it, all created by Franz with the current JeeMon software:

Given how young JeeMon currently is, I’m amazed to see just how much it can already be made to do…

The story I’d like you to take home from this is not how great JeeNodes or JeeMon are (they’re not, they are still far too young and simplistic), but how much freedom you have when everything is open source, hardware as well as software.

It’s time for me to start winding down (with 30..39°C of humid heat, it’s almost a necessity, even…). There will be one or two more queued-up posts on the weblog, and then it’ll be set to read-only mode. In fact, all of internet will become read-only a few days from now, as far as I’m concerned. I’ll be away only part of this summer, but even when I’m in I won’t respond to emails – sorry.

If you ever get bored, there are now 550 posts on this weblog – feel free to browse around, and enjoy :)

TTYL, as they say!

  1. Fascinating little project there. What’s the battery life like? Does temperatures of the fridge impact it or is it still warm enough? I guess a freezer sensor would be an entirely different ball game though!

    As for Jeelabs; it’s an absolute pleasure to find someone who is genuinely enthusiastic about the products he sells, and seems to survive purely on the gratification he receives from his customers/fans – because I can’t believe you can be making much of a profit at these prices!

    • The way Jee Labs is going right now, I can assure you that there’s enough to (carefully) grow the shop and recoup all investments made up front. Sustainability is no longer an issue – staying focused on interesting and useful projects will be the name of the game in the year(s) ahead.

  2. I have enjoyed reading your posts and wish you a good vacation away from the site!

    Looking forward to your return. - Jeff aka mightyohm

  3. Which dallas sensor is giving humidity as well?

    • The other nodes in that screen dump probably use Room Boards, i.e. SHT11′s (plus light and motion).
