Adding software features to Artemis

New things! Everything is progressing nicely. Did additional testing on the 230VAC detection circuit and wrote software to read SHT31 digital humidity/temperature sensors. Also added a ClosedLoop function so analog inputs can be used to compare to store values and have an outputs act on the comparison.

230VAC detection

Finally I had the time to properly measure the mains voltage inputs. No shorts or anything… So I decided to go on and plug in the mains voltage into the Artemis.

The 230VAC detection circuit is connected to D48 (ICP5 on the Arduino), which mean I could potentially measure the exact frequency of the mains AC voltage. Still, I do not require to have that, so instead I built a simple timer that resets if the phase comes up, and counts down if the phase disappears. This way I always have a stable reading on the signal, even when the Artemis accidentally measures on an exact phase zero crossing.

        if (digitalRead(PIN_230V_DETECT) == LOW) // Active? Reset Timer.
                TIM_50HzDetect = 10;
                if (TIM_50HzDetect) // Not active -> count 2 zero and stay.

The first two hours playing with Raspberry Pi

Unbelievable what can be accomplished in only two hours. Today I finally unpacked my Raspberry Pi and started to play with it. Pretty soon I had it up and running… This is going to work out just fine 🙂

The Raspberry Pi. This will be the new brains behind the Paludarium v2.0!

Paludarium to be delivered… Tomorrow!

I got an email today, and guess what… The paludarium will be delivered tomorrow!

I just finished prepping the place it should sit:

The protective base where the glass of the paludarium will sit on. Everything is prepped… Let’s hope I drilled the holes at the correct position.

The kitchen cabinet now has holes drilled at the exact position where the sewer drain and the filter drain will sit. These holes to all the way through the wooden top. AT the back of the top plate I removed a strip of material as you can see. Through this strip I will feed any pipes and wires I need to go in and out of the paludarium.

On top of all there is a protective rubber layer. This will prevent the glass from breaking if the plating is not 100% flat (or has any irregularities).

I am fully prepared for the arrival of the paludarium!

Glass has been ordered!

The word is out… The glass is ordered! Measures are now final, I am very thrilled to see the finished product! I ended up ordering at www.terrariumhuis.nl after visiting the shop where they actually glue at all together. It is a very small shop, yet it delivers most of the terrariums and paludariums in Dutch shops.

They were very interested in building my “special” (as they mostly build standard sizes). At one time I ordered a paludarium from the same shop which was of acceptable quality. Since then they have improved a lot I was told, so I cannot wait to receive the order and building out the Paludarium 2.0! The measures are an exact match to the drawings posted in the Definite glass specs.

As soon as the glass arrives I will post pictures on this blog, and of course all the steps required to build it will be documented here as well! Can’t wait!

Paludarium 2.0 definite glass specs

After checking, evaluating, changing, re-evaluating and changing again, I finally came up with the final design of the glass paludarium. I had already put up preliminary specs in the older blog post “Paludarium 2.0: Ordering glass“, but now specs have changed and are definitive. Bring forth the offers from different paludarium building companies!

Changes in the new design

Some adjustments were made in when finalizing the design for the glass. The most important changes: Read more »

Go with the Flow

As I’ve started to think up Paludarium 2.0, more and more ideas are popping up. The most recent one: How to build the water household. With all the things I want, and all the technology I can build, I am now thinking up the specs and features I need/want, and how I can build them so that it will actually work, and most important, KEEP working.

Specs for the flow of water

I have quite an extensive must have / wanna have list. Here they are in random order: Read more »

First idea for the cabinet

As Paludarium 1.0 is sold and gone, I’ve begun to design the cabinet that will be built under the new paludarium. I plan to use kitchen cabinets for this purpose, and include a section to put the TV on as well.

Using kitchen cabinets

When building our new kitchen, it dawned on me that using kitchen cabinets might make the perfect cabinet Read more »

Paludarium 2.0: Ordering glass

Just as Paludarium 1.0, I decided to once again not build the glass tank myself, but have this pre-built. In order to be able to get what I want, I needed a technical drawing of the glass tank.

General sizing

General sizing was quite straightforward. I want to reuse my old paludarium lighting hood, so the top measures should be the same as the old one: 100cm wide and 60cm deep. The current height of the paludarium is 100cm (divided in 30cm water, 70cm land). I found the 30cm of water to be somewhat too low, and really want a water height of 50cm. That would bring the Plaudarium to a total glass height of 50+70 = 120cm. Quite a construction!

1.5 Year stop-motion video from Paludarium 1.0

So why would you put up a webcam to a paludarium and save a screenshot every day? Well, because you can! Now that I was working with videos and youtube anyway, I figured to check out my fileserver and see how many captures where there. I was surprised to see that my fileserver had been capturing screens for over 1,5 year! Now I have strung them all together into a short video for all to see.

Lighting of the Paludarium 2.0

Paludarium 2.0 is going to utilize the same lighting system as the current (1.0) version. Because I am often asked about this technology, I decided to translate my original post (see Verlichting van het paludarium (in Dutch) and post it here.
