Another use for recycled hard disk platters -- the centre electrode of this capacitor array is a platter from an ancient 133mm hard drive. Probably a ten megabyte MFM. The negative terminals of the capacitors are bolted to holes drilled around the periphery of the platter. Positive terminals are wired together using wire abandoned at a jobsite by contractors. Seperate bits of wire come off of each cap and are all run together to one wire that is shorted to the platter to make the spark.

The camera is a 1Mpx POS held in my hand while I complete the circuit with the other hand.
The Combined Array for Research in Millimeter-wave Astronomy (CARMA) was an astronomical instrument comprising 23 radio telescopes. These telescopes formed an astronomical interferometer where all the signals are combined in a purpose-built computer (a correlator) to produce high-resolution astronomical images. The telescopes ceased operation in April 2015 and were relocated to the Owens Valley Radio Observatory for storage.

April 4, 2019 — The annual student art exhibit displays an impressive array of recent creations by NMH students. The exhibition opens Friday, April 5, with a reception at 6:30 pm in the Gallery at the Rhodes Arts Center, and runs through May 5.
Among the 60-plus works in the exhibition are pencil and charcoal drawings, photographs, oil and watercolor paintings, prints, collages, and photographs. There’s also plenty of three-dimensional art, including assemblages, ceramics, sculptures in Creastone, wood, and metal, and wearable art in the form of customized sneakers.
Styles vary from ultra-realistic to abstract. One painting represents NMH’s Memorial Chapel as Van Gogh might have painted it. A menagerie — bird, fish, rabbit, insect, octopus, and whale among them — has been created from nothing but ingeniously shaped wire. Several pieces make overt commentary on life, from the panic of impending school graduation to the horrors of war.

Este es el árbol de Navidad que he diseñado para el trabajo.
La estructura no es de origami pero si las bolas que lo adornan.Me ha costado un poco hacerlas iguales que el árbol porque lo diseñe primero con los tubos y luego con los Hexabonitos.
Está hecho con mas de 700 tubos huecos de unos 10 ctm de largo de policarbonato unidos con alambre de acero formando tetraedros.
Tiene una tira de luces de Navidad de con 180 bombillas de colores aunque en las fotos no se aprecia la luz..
Es dificilísimo coger el destello. Árboles de hexabonitos tendrá más de cincuenta colocados cada uno en un tetraedro.

One of the 7 radio telescopes that make up the Multi-Element Radio Linked Interferometer Network (MERLIN), an interferometer array spread across England and operated by Jodrell Bank. It is used to observe Radio-loud Galaxies, Quasars and Hydroxl (OH) in intersellar gas clouds.
This antenna is at the Mullard observatory at Barton near Cambridge. _30A4563
