Whooops – Little Registrar sent a note to you all, but shouldn’t have…

Dear Readers,

please accept my apologies that our faithful newsletter informed you about a post that was password protected. This was a mistake, as we are testing our new data logger at the moment and I needed a website to test if we all could have access to our climate dates from all over the world (or, in fact, from all our storages and offices). Didn’t have an idea that this would be sent out via our RSS feed just like any other blog post.

Well, anyway, to keep you in the loop: what is happening at the moment?

Over Christmas I was experimenting with arduino and other microcontroller boards. Of course, even if I try to do something just for fun, I end up doing something museum related. As I needed something to build, I built a data logger. And if it’s already built, why not take it to work with me?

There it glows... the experimentation zone at Christmas.

There it glows… the laboratory at Christmas.

At the moment one little prototype of the “Little Registrar” keeps a good watch over our climate in one of our offsite storages and sends its data to a website. And since this week this other little fellow records the climate in a storage room at our museum and logs it to a SD-Card:


As you see by the q-tip that serves as the restart button this is all in the prototyping stage at the moment. In fact, the “Q-tip Registrar” was a quick answer to an urgency call by our conservators. Assembled with parts I still had at hand, including an old cardboard box, a screw anchor, some ethafoam and, yeah, a q-tip.

Those who follow @RegistrarTrek on twitter know that I promised to write what we did and how and I will do, as soon as we passed the prototyping stage (and stopped creating e-mail bombs).

Have a great weekend, all!
