Um Candelabro de LEDs:
I built a few cool projects I found on Instructables.com and now it's time for me to contribute. This is a LED chandelier that I made using Christmas LED string lights. It not difficult to make but it takes some time. I think it's totally worth it and the end product look awesome!

Tomem lá Ciência, um Trans-Iluminador de Ultra-Violetas, para o vosso Laboratório de Biologoa Molecular, e sabe-se lá o que mais:
UV-transilluminators are used in molecular biology labs to view DNA (or RNA) that has been separated by electrophoresis through an agarose gel. During or immediately after electrophoresis, the agarose gel is stained with a fluorescent dye which binds to nucleic acid. Exposing the stained gel to a UVB light source causes the DNA/dye to fluoresce and become visible. This technique is used wherever the researcher needs to be able to view their sample, for example sizing a PCR product, purifying DNA segment after a restriction enzyme digest, quantifying DNA or verifying RNA integrity after extraction.
