Diatom Decorative Bowl

PolymathDesignLab — Wed, 25 Nov 2009 06:01:55 GMT

This intricate bowl is based on the lovely design of a type of tiny algae called diatoms. These phytoplankton come in all sorts of incredible shapes, with silicate cell walls (called frustules) that show nearly ornate patterns of pores under a high-powered microscope. The first edition of this bowl is currently on display at the Phylogenetic Museum at the University of Jena, Germany as part of a Diatom-focused exhibition. To make this bowl, the pattern of one form of diatom was hand drawn, then laser cut from white acrylic. The shape is then heat formed into a bowl with a depth of approximately 2" and measuring around 7.5" diagonally. Attractive and modern enough to stand on its own, it is also sized perfectly to hold things like business cards, keys, or candy. Want another color? Just let me know your preference and I'll set it up- this can be made in any of the 3mm acrylics that Ponoko carries! This will be cut when you order and shipped to me for forming, so please allow 2-4 weeks minimum. Thanks!

Helical Symmetry - laser cut double helix DNA earrings

morphologica — Wed, 14 Jul 2010 15:48:05 GMT

Stunning laser cut earrings formed from elegant intertwined DNA-like strands. Beautiful and unusual. A truly unique piece inspired by the beauty of neuroscience Laser-cut from black acrylic, crafted into beautiful drop earrings with silver hooks. Approximate earring length from top of hook is 2.6 inches (6.7cm). Created using high quality silver-plated components. Sterling silver hooks available on request (smaller hooks without ball feature) via 'message to seller' box during checkout. Earrings are created with new hooks that have not been worn. *This DNA design is also available as a necklace or as earrings in a larger size or different colour* .......................................................................................................

About the design and production process: Each piece starts its life as a sketch on paper, then is modelled digitally and cut by laser beam, before finally being assembled into a truly unique piece. During my PhD research, I have discovered that science can be surprisingly beautiful- single cells viewed under a microscope, intricate networks of cells important for learning and memory, and even the curving structure of the brain itself. I have tried to capture some of this beauty in the Morphologica pieces, focusing on the shape or morphology of a variety of subjects studied in neuroscience. Copyright Morphologica

Articulated Crayfish

chosetec — Sat, 09 Mar 2013 16:54:55 GMT

This fully posable crayfish has moving joints - antennae, eyes, legs, claws, and tail - printed in place. It is inspired by the handmade articulated Japanese sculptures of insects and crustaceans, 'jizai okimono' which were popular in the Meiji era. This modern interpretation is 3D-printed in white sintered nylon plastic, which is relatively tough and can be painted with acrylic paints.

Mouse Recording Studio

LabDaemons — Mon, 15 Apr 2013 16:23:19 GMT

The Mouse Recording Studio is a complete recording solution for monitoring mouse ultrasonic vocalizations. This comprehensive system incorporates various sensors and actuators controlled by a base station that sits outside the chamber to allow user input without disturbing the animals inside. The automated system can monitor environmental variables such as temperature and relative humidity to help you meet animal care standards. Additionally, you can monitor background sound levels through a standard microphone and animal movement through a motion detecting camera. The system is designed to easily integrate with the wide range of ultrasonic recording amplifiers and a microphone (model CM16/CMPA) from Avisoft to automatically start and stop recording sessions. Lighting can be controlled manually (red or white light) or on a timed schedule for long-term housing. Male courtship songs can be triggered by precise delivery of female urine into the recording cage through a peristaltic pump or by releasing a female mouse into a partitioned cage designed to allow olfactory contact but prevent copulation. The system is controlled by Arduino open-source hardware (Uno R3), and open-source code is provided to get you up and running immediately. The following add-on modules easily extend system functionality: 1) Hall sensor to monitor door opening and closing 2) Second camera that can be positioned freely positioned 3) Audio/Video synchronizer to help precisely align recordings 4) Automatic release cage THIS KIT INCLUDES THE FOLLOWING COMPONENTS AND DETAILED BUILD INSTRUCTIONS: Arduino Uno R3 BlinkM RGB LED (x2) RCA Jack (x2) DC Barrel Jack Adapter 9VDC 650mA Wall Adapter Power Supply 12VDC 600mA Wall Adapter Power Supply 6 Foot A to B USB Cable To complete the build you will need to order the additional electronics items listed below.
