    I thought I would share a few new photos of one of my vivariums. I have posted a few older photos of it in another thread here, but I thought these updated photos would be better off in their own thread.

    This is an Ecuadorian-themed tank; not exactly a "biotope" as it is somewhat idealized, but from my research all, or most, of the plants can be found in central to east-central Ecuador, or thereabouts.

    The current plant list includes:

    Pearcea hypocyrtiflora
    Peperomia emarginella
    'Ecuador'
    Peperomia sp. 'Baños, Ecuador'
    Philodendron (sect. Pteromischium) sp. 'Ecuador'
    Plagiochila sp.
    Pleurothallis niveoglobula
    Stelis
    sp. 'Ecuador'
    Trichosalpinx sp. 'Ecuador'
    Various mosses

    Definitely one of the most gorgeous terrariums I've yet seen, I've admired this over on dendroboard for a while. If you have time do you mind reposting some of the construction details here?

    Neat! If it is not a forbidden topic, could you please share technical details of the setup?

    Thank you all for the comments! I am quite happy, myself, with how this project has turned out.


    Here are the details of this cylinder:

    The overall dimensions of the cylinder are approximately 14”x20” (~35cm x ~51cm). It is constructed out of 1/32” polycarbonate (Makrolon) sheet that has been bolted together at the back (so, there is a seam). The base is 1/4"x16”x16” polycarbonate that I later framed with 3/4" x 2" mahogany hardwood. The top is 3/16” glass with three 3/4” holes drilled for ventilation and one 40mm fan providing circulation - this runs on the same timer as the lights (12 hours on/12 hours off). The lighting[​IMG] was originally supplied via three 6W CREE LED[​IMG] spotlights, but I recently made a new fixture using a 3/16" thick aluminum plate ring as a heatsink, and three neutral-white and three cool-white CREE XM-L2 LEDs, with 60° optics, running on a home-made driver. The subject piece is made from one large and one small Hygrolon liana accented with a few small pieces of cork bark. The temperatures range from intermediate to warm conditions. It gets watered about once, sometimes twice, per week.

    How do you bolt the edges together and ensure that it is circular? I've tried something similar, but had a hard time making it round.

    Nothing special; I have seen others use a piece of aluminum bar stock (~1/8" x 1/2") running the length of the back to ensure a tight seam. I think the main concern is getting everything square and having a tight-fitting top - if you get your top round, and everything else is square, your bottom should be round too.

    Shaun, beautiful and it sounds like pretty hard-core DIY!

    Is passive cooling enough for XM-L2? What current are you driving them at? XM-L2 is very nice, but it is pricey. Cree announced a couple months ago that the next generation XHP has similar performance, with much cheaper price. They should be available by the end of year. This will be exciting for others who is interested in something similar:

    http://www.cree.com/xhp

    In another thread, Calvin had a link to DIY drivers (in fish forum). I couldn't figure out what is the advantage. Do you know advantages of home-made drivers (vs. pre-made constant current drivers such as Mean Well)?

    Thanks, naoki.

    The driver has the capability of running them at the full 3A, but I'm running them at about 40-45% of full power. At this current they are only slightly warm to the touch.

    I don't know anything about the drivers available on the market, so I can't really comment on the advantages/disadvantages of DIY versus store-bought. The main advantage I can see would be cost - the cost for this driver in parts was less than $5; I didn't see anything in that price range when I did a brief search online.

    $5 sounds really good! Now I'm interested. If you have a pointer to how to make it, I appreciate it!

    Beautiful!
    What is the total cost to have one built, and with all the necessary equipments?
