Yep.
The tape transport that was originally partnered with these may still be extant.
(Maybe not.)
Update: It is not. (sad face.)

A schematic diagram for an upcoming project: a crystal set receiver based on the Australian "Mystery Set" designed in 1932 (it's called a "Mystery Set" because the tuner is an incomplete circuit and yet, performs better than a "correctly" designed set). The set will be housed in a wooden box with a lid with lock and key (in the style of an old English crystal set) and a dummy crystal detector for looks only (the actual detector will be a 1N34 type germanium diode). This radio will also have a band switch for longwave, medium wave (standard AM broadcast), and shortwave. Note the use of inductors in series and parallel combinations, and the use of a second detector diode for the signal strength meter. See www.flickr.com/photos/14275763@N08/24133301200/ for photo of some of the parts.
Note: To cover the European LW broadcast band, use 230 turns on L2.
Silicon single crystal grown in a lab, i.e. the element silicon (Si) in totally pure state in a continuous crystal latice.
This material cut in slices is the base of the electronic industry; in expressions such as "silicon age" or "silicon valley" this is the material that fuels the metaphor.
When we hear the word "crystal" we often associate to something with flat faces that meet in edges, as is the case for minerals, naturally grown crystals. Nevertheless the crystaline state of a material refers to the internal structure, the totally aligned organization of the atoms. The process by which the Si crystal on the photo is grown does not yield faces, but still, this is a true crystal.
(on the other hand if we cut a piece of glass in form of a hexagonal quarz crystal that will not be a crystal, just shaped glass.)
Although the element silicon is extremely common in natural rocks (all silicates contain it), it is never found in pure state naturally, only in combination with other elements. (most commonly as quartz and feldspar)

Silicio monocristalino cultivado en un laboratorio, es decir el elemento silicio (Si) en estado completamente pura en una estructura cristalina continua.
Cortado en rodajas este material es la base de la industria electrónica.
Just got some new kit, a logitech c920 for some podcasting, and hangouts. Now just for some lights so it stops looking so grainy.
有幸獲得一台NIKON FM2 BLACK,感謝豪鬼的割愛
話說我人生的第一台相機是一台銀色的FM2
那時讀廣設科的學生,都會被老師勸敗買一台FM2
因為那是一台有著高速快門的全手動機種,有著適宜的售價
通常也都會配著一顆AIS 50mm f1.4
在標準不過的配備,卻也意外地好用
很不幸的,研究所初期實在太窮,所以我賣掉了我第一台的銀色FM2
現在從好友手中接下這台狀況良好的FM2
而且還是黑色的!!!!
我期待著重新再使用它的時候
在為我記錄著全新的時刻
(在廟口夜市吃著紅燒鰻,看著這台美麗的機器)
From some t-shirt scraps, I sewed a pocket to hold the arduino and battery. I added snaps to the pocket and snaps to the back of my dress, so that I could hang the arduino from my clothes. This way, I could plug all the wires into the arduino and be sure they were in the correct pins, and secure them with some tape; put the arduino into the sock; and ask my co-worker, when it was time for the party, to simply snap the sock to my dress--easy.
Similarly, the switch for the red eyes is connected with snaps. Wires (that plug into the arduino) are soldered to the female halves of the metal snaps. The male halves are sewn with conductive thread to my dress. (Conductive thread! Yes!) The conductive thread runs inside my dress, down to my hip, and terminates in two safety pins. I threaded it inside bias tape to prevent the two threads from touching and causing a short. When the arduino wires are snapped to the conductive-thread snaps, the arduino is connected (conductively) to the safety pins. When I touch the safety pins to each other, I close the circuit, triggering the red-eye effect.

Experiment in drawing moving vector dots on a video vectorscope using an FPGA to synthesize a chrominance signal (using only the luminance channel) that is slightly off the colorburst frequency, causing the rotation. The synthetic D1 video signal is sent to an encoder chip to create the analog video signal.
